2. Milk Processing

(a) Liquid milk processing
Milk is widely considered as one of the world’s most valuable protein food. As a raw material, it is available in various forms, and it is processed into an ever increasing variety of nutritional products. Gte Ltd offers Dairy plants that include small milk processing equipments for handling milk in liter capacity of 1000 to 5000 litres per day. A number of products like ghee, butter, cream, toned milk, double toned milk and skimmed milk can also be manufactured. Milk is first received in a dump tank from the road milk tankers. It is then chilled in a chilling unit to 4ºC. This chilled milk is then pasteurized in a milk pasteurizer and cream is separated from milk in by the cream separator to get skimmed milk. Milk is standardized depending on the requirement of toned milk, double toned milk, skimmed milk or full cream milk. The separated cream is further processed to manufacture ghee and butter. The pasteurized skimmed milk, toned milk or double toned milk is sent for packing in pouches in the packing machine for various capacities like ½ kg, 1 kg pouches. The plant will be in operation for 20 hours in a day.

(b) Milk powder plant
Milk Powder is a processed dairy product made by evaporating milk to dryness. Drying extends the shelf life of milk apart from reducing the weight and volume and lowers the cost of transportation also. The initial solid in the milk varies from 7.5% to 12% depending upon type of milk and the final moisture in the powder, ranges between 2.5% and 5%. Since drying is an energy intensive process, Gte Ltd offers the solution to make the process energy efficient & cost effective.

Milk Powder Plant Consist Of:
· Multistage Evaporator
· Two/Three Stage Dryer

Process Discription
Milk is concentrated up to 45-48% solid concentration in Multiple Effects Falling Film Evaporator with TVR/MVR System. Evaporation of water takes place under vacuum conditions and at low temperature. A Five Effect Falling Film Evaporator with TVR over 3rd effect will have specific steam consumption of 0.12 kg/kg whereas a seven effect plant with TVR over 4th effect gives specific steam consumption of 0.09 kg/kg which is equivalent to energy consumption in MVR evaporator.

During drying in spray dryer, the excess water present in free form between the particles of the dry solids gets evaporated easily. Whereas last stage of evaporation demands more energy as water contained in pores and capillaries of the solid particles need to be evaporated. These last drops of water are removed from milk solid in a Vibro Fluid Bed Dryer which requires less energy for removal of balance moisture.

The combination of multiple effect evaporators, spray dryer with fines recirculation system and use of a ‘Vibro Fluid Bed Dryer’, produces instant quality powder.

Lecithination System
We also offer lecithination system integrated with the milk powder plant to manufacture whole milk powder. Addition of lecithine produces instant quality WMP.

To manufacture sweetened condensed milk the pasteurized milk with added sugar syrup is taken to the evaporator and concentrated to desired level of concentration. The product is then cooled in such a way that lactose forms very small crystals in the supersaturated solution. After cooling & crystallization the sweetened condensed milk is packed in pre-sterilized cans or in barrels.

Evaporated Milk Plant
Evaporated Milk is a sterilized product. The product has a large market in tropical countries. It is used where fresh milk is not available. It is also used in cooking and as a Coffee/Tea Whitener.

The manufacturing process for the evaporated milk involves precision standardization of the fat content and the dry solids contents. This is followed by heat treatment which partly destroys the microbes present in the milk. The heat treated milk is then fed to an evaporator, where it is concentrated up to 26% (8% Fat and 18% SNF). The milk is then homogenized (homogenizer) before being cooled. Checks are carried out on the coagulation stability of the milk before it is packaged in the sterilized cans. The product is then placed in an autoclave for sterilization. Finally the cans are cooled before storage.

The different stages in the production of evaporated milk are:
· Standardization
· Evaporation
· Homogenization through homogenizer
· Cooling & Inspection
· Packaging
· Sterilization
· Cooling
· Storage.

Malted Milk Plant
Malted Milk is a powdered food product made from mixing of standardized milk, malt extract with wheat flour, and cereal grains in such manner as to secure complete hydrolysis of the starchy material, which is evaporated until it forms a high viscous solution which is then dried in a Vacuum Tray Dryer / Vacuum Band Dryer.

The manufacturing process consists of the following stages
· Blending of ingredients like malt extract, milk or milk powder, grain flour etc in required proportion.
· Concentration of the slurry in evaporator.
· Vacuum Drying of the concentrate.
· Pulverization of the dried product.
· Packaging of malted food.
· Storage.

3. Other Processing Projects
Instant coffee plant
Coffee is a brewed beverage prepared from roasted seeds, commonly called coffee beans of the coffee plant. Due to its caffeine content, coffee has a stimulating effect in humans. Today, coffee is one of the most popular beverages worldwide. Approximately 90% of world coffee production is represented by the species Coffea arabica; about 9% by the species Coffea Robusta; with minor production from the species Coffea libericia. Most processed coffee available in the market is differentiated in terms of aroma, blend and flavour which comes from the way it is processed. Processing coffee to a perfect blend and taste is an art and requires excellent techniques of extraction, roasting, concentration, aroma recovery, spray drying and agglomeration.

Gte Ltd has supplied coffee extractors, instant coffee powder plants, aroma recovery systems, evaporators, spray dryers and agglomerator to quite a large number of instant coffee manufacturers in Africa and the systems are running successfully. With core competency lying in the field of evaporation and drying technology, Gte ltd has collaborated with leading manufacturers of green coffee cleaning, blending, roasting and grinding equipment manufacturers to supply instant coffee plants on turnkey basis. We have also collaborated with leading companies for supply of continuous freeze drying equipment for production of freeze dried coffee. Coffee produced from our plants have excellent aroma due to our extensive knowledge and experience on coffee. Gte Ltd offers the most energy efficient soluble coffee processing technology and is in a position to supply upto 15TPD instant coffee production plant. Coffee plants with smaller capacities are also available e.g. 50 kg/hr, 100 kg/hr, 150 kg/hr, 200 kg/hr, 250 kg/hr of instant powder production capacities. Gte Ltd has already designed, engineered and supplied a few complete plant on turnkey basis and is negotiating for more.

The process in brief:
1. Cleaning & blending of green coffee
The first step is thorough cleaning of defective beans and separation of nails, stones, dirt & dusts. Blending of beans is carried out before roasting by installing volumetric feeders at the outlet of the silos. Through this process various kinds of blends are obtained depending on the taste and demand of the market.

Roasting of coffee beans develops the flavor and aroma which depends on various physical & chemical changes which occur during roasting. Degree of roast & roasting temperatures are very important and plays an important role in deciding the flavor and colour of the final product..

Green coffee cleaning

2. Roasting & grinding of green coffee
The third step is extraction of ground coffee through a continuous process in a pressurized vessel with hot water. To get a better yield seven batteries of counter column extractor cell is used featuring extraction under closely controlled system. Extraction is greatly influenced by factors like type of green coffee beans, degree of roast, type of grind, ratio of coffee to water & mode of heat input.

Coffee extraction

3. Clarification system
The extracted coffee solution is passed through a centrifugal clarifier to separate the insoluble solids.

Clarification unit
4. Aroma recovery cum concentration system (ARC system)

This is done after clarification extracted coffee liquor is passed through the aroma recovery cum evaporation plant. In the plant, the volatile aroma is stripped off from the coffee before it enters the evaporator. Based on the boiling points of the aroma constituents Gte Ltd has developed a new technology for the extraction of this aroma without diluting them with the water vapours so the result is more pure and concentrated aroma. This technology is called the ARC System which stands for AROMA RECOVERY CUM CONCENTRATION SYSTEM which is integrated with the evaporation system. In the evaporator concentration of the extract is done through multi-effect evaporators with TVR systems for concentration up to 50-55%. It is possible to concentrate the extract further up to 65-70%, to reduce the load on freeze drying system.

Aroma recovery unit

5. Coffee concentration
the next step is concentration of the extract through multi-effect evaporators with tvr systems upto 50% concentration is achieved.

Evaporation section – Part 2 calandrm section

7. Spray drying system
the concentrated coffee is then converted to instant coffee powder by spray drying. Drying is done under controlled conditions to protect and preserve aroma and flavor in the coffee.

Spray drying section

8. Agglomeration system

Lastly, the Spray dried powder can be converted into soluble (instant) granules in an agglomerator tower by Re-wet agglomeration technique. This technique results in the formation of bigger sized porous particles and reduces the bulk density thereby increasing the instant ability of the powder. Hence when a spoon of this agglomerated powder is put in water, it disperses completely due to the osmotic pressure of the liquid.

Agglomeration section
9. Packing & filling

The instant coffee powder is then taken to the tote-bins for storage and packing. For filling into tins or jars, vacuum operated filling system is used. For filling into sachets, a form fill-sealing machine is used. The filled containers/flexible packing are packed in the shipping cartons and sent for dispatch to the finished goods warehouse.

Unique features of instant coffee plants
• integrated evaporation and aroma recovery system, both of which can be controlled from one plc.
• saves lot of energy as pre-heating is carried out with generated vapours in the evaporator.
• the system provides aroma at a higher concentration and is not diluted with water vapours.
• availability of concentrated aroma allows higher concentration feed to spray dryer, which increases productivity.

· Less down time for maintenance purposes.
· Possibility of expanding capacity upto 100%.
· Gte Ltd has supplied more than 50 spray dryers; the biggest one is having a powder output of 38 TPD.
Freeze drying system
Instant coffee powder is usually made by evaporation of coffee extract upto 40-45% concentration by use of an evaporator followed by spray drying at a high temperature (180-220 °C). This results in change in appearance, colour, loss of aroma and taste.

However, use of freeze dryer retains aroma, improves appearance and taste because freeze drying takes place at a low temperature which minimizes heat damage and retains volatile components (aroma). It also increases the shelf life of the dried product as compared to standard drying practices.

Freeze-drying involves dehydration of food products at low temperature and pressure. As a result only the moisture is removed, leaving the molecular structure intact. The end product is light in weight with least or no change in volume. Worldwide freeze-drying technology is considered as the ultimate amongst all other dehydration methods. Hence this technique is currently being used for the production of instant coffee.

In a freeze drying system, concentrated coffee (42-45%), is first freezed and then exposed to a low partial pressure (4.6 mmHg) of water vapour when ice sublimes directly to vapour leaving behind dried coffee.

Freeze drying is an expensive process in terms of capital, expenditure and operating cost but results in excellent product quality.

Freeze drying of coffee involves four steps:
Pre-freezing coffee concentrate up to -5 / -10 °C followed by foaming.
Freezing of the prefreezed coffee liquor at -50 °C in a blast freezer.
Sizing of the freezed coffee particles to a granular size of 3X3mm.
Sublimation of the ice in a vacuum freeze dryer (VFD) under vacuum (0.5 torr) and controlled temperature.

Gte Ltd has developed this technology successfully in their R&D laboratory, where a pilot plant has been set up for demonstration.

Advantages of freeze dryers are:
· Continuous plant, which needs less space.
· Most energy efficient.
· Minimum heat damages, which helps in retaining good appearance and colour of the product.
· Retaining most of the Aroma due to the use of most innovative Aroma recovery.
· Quick and complete re-hydration due to porous structure (Instant)
· Less man power requirement (fully automated)

Instant tea plant
Gte Ltd has designed this plant to manufacture instant quality tea from leaves. Tea Extraction Plant provides a fine quality of tea. The process in tea processing plant includes extraction, separation of waste, evaporation and spray drying.

Plant size can vary from a minimum of 5 kg/hr of instant tea to a very large capacity like 1000 kg/hr.

The plant is made complete in Stainless Steel wherever product is in touch. The space required for a plant of this size is 500 sq. yard.

Fresh Green leaves of the plant Camellia Sinensis is one of the main raw materials for this instant tea production. This type of plant is available throughout the year in abundance.

The Process
· Instant tea is manufactured from black tea by extracting the brew from processed leaves, tea wastes or undried fermented leaves.
· The extract is concentrated under low pressure and dried to powder by any of the processes including freezing, drying, spray-drying and vacuum-drying.
· Low temperatures are used to minimize the loss of flavor and aroma.
Instant green tea is manufactured by similar methods but hot water is used to extract liquor from powdered leaves. Instant tea needs to be stored in airtight containers or bottles, because they absorb moisture very quickly.
Refined iodised salt processing plant

Main source of salt is rocks, sea and lakes. Maximum consumption of salt is in its natural form after being produced from sea or directly from rock. But with time, awareness of uses of salt has grown manifold and the demand of refined iodised salt is increasing tremendously during the last few years. Refining not only helps in increasing purity of salt but also improves flow-ability and use of anti-caking agents helps in keeping quality too. During refining and drying process, iodization is done which is important for human body to avoid various diseases. Refined salt is further graded for various applications like kitchen salt, table salt and industrial salt.

Salt refinery is mainly of two types:
· Mechanical Refinery.
· Vacuum Refinery

Mechanical salt refinery
Crude Salt is fed into the feeding hopper of suitable capacity and it is then transferred to a belt conveyor. This belt conveyor will be fitted with a magnet to remove rubbish metal and will also be provided with a belt weigher with totaliser. Crude salt is pre-washed in special washing system. This is then fed to the feed in hopper of the wet mill for grinding. Wet mill is used to grind the salt with the help of saturated brine solution. This mixture is then passed to the slurry tank that is fitted with a slow speed agitator.
This slurry is then pumped through centrifuges, high pressure pump, centrifugal pumps, axial flow pumps, gear pump to the wash tank by a slurry pump, wherein dirt is removed from the slurry. The overflow from the wash tank is collected in a clarifier wherein brine is clarified and re-circulated in the plant. This is then pumped to the hydro cyclone by a slurry pump for thickening of the slurry.

Drying & finished product handling section
The salt crystals from the centrifuge are dried in a Fluid-Bed Dryer. The crystals forms a layer on the perforated sheet present in the drying chamber of the fluid bed dryer and is dried by means of hot air from a thermic fluid air heating/Indirect air heating system. The fines are removed from the exhaust stream in the cyclone separator and are collected separately. Dry salt is from the outlet of the fluid-bed dryer and is passed to the sifter through a bucket elevator. The oversized salt is separated in the sifter and the over sized salt crystals is passed to the pin mill for further grinding and salt is passed to the feed in hopper of the blender wherein free flowing agent is added. This free flowing salt is then sent to the storage silo for packing.

Vacuum refinery
The process involves dissolving of salt in water and making a saturated solution of salt. The saturated brine is pumped out to a brine clarifier, where the insolubles settles at the bottom of the clarifier and clear brine solution is taken to a brine tank. In the brine tank required chemicals are added to precipitate out magnesium and calcium salts present along with the salt. The brine is then filtered and taken to the final brine tank. From this tank saturated brine is fed to the continuous evaporation plant where Crystallization takes place and slurry is pumped out to a concentrate tank. This salt slurry is then pumped to a hydro-cyclone battery to get a slurry concentration up to 50-60%. This slurry is fed to a centrifuge, and from the centrifuge salt cakes with 4-5% moisture comes out. The salt with 4-5% moisture is fed to a fluid bed dryer through a screw conveyor where the iodization is completed.

In the Vibro Fluid Bed Dryer, the salt is fluidized by hot and atmospheric air for drying and cooling the salt. The salt is then taken through a bucket elevator to a sieving machine. The oversize particles are collected and sent for re-dissolving in the final brine tank. To the crystallized salt is then added the free flowing agent in a screw mixer and finally sent to a storage silo.

The salt packaging is done from the silo by a FFS machine in 1 kg. Packs or it can be packed in bags as per requirement.
Honey processing plant
Honey being a biological substance and intended for food & pharmaceutical use needs greater attention in quality and its handling. The moisture content in honey plays an important role in deciding the quality of honey. Honey with more than 20% moisture is thinner in consistency. The moisture content in honey increases due to hygroscopic nature of honey in which the surrounding atmospheric moisture is absorbed by honey. If the moisture content is more than 20% the honey is liable to spoilage due to fermentation & granulation. Considering the present practice of collection, storage & handling of honey under uncontrolled conditions including climatic factors the honey needs processing, reduction of moisture and packing by utmost care to protect the valuable natural properties.

Water (Moisture) – 20%
Fructose (Levulose) – 37%
Glucose (Dextrose) – 34%
Sucrose (Non Reducing Sugar) – 5.0%
Total Ash (Minerals) – 0.25%
Acids Organic – 0.20%
Proteins, Amino Acids, etc. – 1.50%
Other ingredients including pollen grains – 1.05%

Brief process description
· Liquification
· Pre-Heating and Straining
· Micro-filtration
· Inactivation of Yeast Cells (Processing)
· Vacuum Evaporation
· Cooling of Honey

Egg processing plant
Eggs are an excellent food containing many essential nutrients. The higher nutrients density of eggs relative to their calorie content makes them excellent food. Two large chicken eggs contains about 12 gms of protein, 1.2 gms of carbohydrate 11 gms of lipids and substantial amount of iron, phosphorous, vitamin A, E, K and most of the B complex vitamins. White portion of the egg contains almost 90% water, but contributes about 50% protein, niacin and riboflavin. Most of the vitamins and minerals are found in egg yolk. The yellow color of egg yolk is due to the presence of xanthophylls pigment.

Eggs are taken from the cold storage and weighed. Dirty eggs are sent to a washing machine before they are broken. Rotten eggs are removed by candling. Egg breaking can be done manually or by using continuous egg breaking & separation machines. A skilled operator can break 500 to 800 eggs per hour. In case of large handling fully automatic machines are available.

For processing egg whites, efficient separation of egg whites from yolks is of great importance as no yolk must contaminate the whites. Even a small amount of yolk oil in albumen greatly reduces the quality of the product. Modern machines can achieve the limits of yolk oil in egg white to the extent of < 0.02%, which is acceptable.
In the production process of whole-egg or egg-yolk powder, whole eggs/egg yolks are homogenized, filtered to remove membranes and fragments of shell pieces. Pasteurization will be done at 64 to 66°C, with a holding time of 2 to 4 min. This ensures inactivation of most of the microbes such as E. coli and Salmonella which can cause ill health, if not inactivation.

After pasteurization whole eggs (solids content 20 to 27%) or egg yolk (solids content 40 to 48%) are fed to the spray dryer. The drying-air inlet temperature ranges between 150°C and 200°C. Final powder has a moisture content of 2 to 4% and bulk density of 0.3 0.35 g/cm³. The powder is then packed suitably after subsequent cooling.

· Homogenization of mixture
· Spray drying

Plant operations
The canisters, stacked in layers on a pallet, are placed on a rotary table that discharges into a downward chute made of twisted metal rods.

The worker can manually place a scoop into each canister as it passes on through the conveyor. The row of cans pass beneath a rotary auger filler set to deposit the correct quantity of coffee. After filling, the canisters pass through a can seamer that applies a metal bottom. This is followed by ink-jet coder that prints the manufacturing date to the metal bottom.

After this, the twister sets the canisters upright on the conveyor that is conveyed to an applicator for plastic overcaps. Side belts move the cans through the unit and the over-caps are fixed on the top portion of the foil membrane. Finally, the cans are delivered to a rotating accumulation table.

Starch, glucose & its derivatives
Starch can be produced from various starch containing materials like maize, cassava / Tapioca roots, potatoes, wheat, rice etc. There are different technologies for each raw material for recovery of starch. Starch is mostly used for industrial purposes

Being a pure renewable natural polymer, starch has many applications, its significance as a polysaccharide being able to breakdown into their monomeric and or oligomeric components leading to production of Dextrose, glucose, fructose, maltose & sorbitol.

Zero liquid discharge section (flow)
distillery waste water handling by evaporation and drying
The technology is based on basic principle of reduction of quantity by concentrating the effluent and subsequently drying it to a Powder / Mixed Fuel form which can be used as an alternative fuel for boilers and as an organic / inorganic fertilizer for plant growth.

The evaporation process:
Distillery Effluent is fed to the vacuum evaporator to concentrate maximum up to 60% solids concentration. The total process is under vacuum and the vapors generated in the system are re-used to economize steam consumption. In order to reduce steam consumption in multiple effect evaporation system the thermal vapour recompression system is used. The thermal vapour recompression system use Vapours generated in the evaporator and compress it by steam and the compressed vapours are used as heating medium in the evaporator. Water recovered from the evaporator has low BOD value and can be recycled in the plant.

The drying process (Zero Liquid Discharge Section):
The resultant slurry (concentrate) is fed to the drying section for converting the liquid concentrate to powder / mixed fuel (mixing with Secondary Fuel e.g. Bagasse, rice husk etc.) form. The air heated by steam radiator or hot air generator is fed into the dryer. The whole system is designed to obtain the optimum results. The emissions from the dryer are within the norms specified by the Govt. of India. This powder / mixed fuel can be used as an alternative fuel to steam boilers.

Main thrust of the technology
The Basic thrust of the technology is to reduce the quantity of Effluent by a maximum possible extent in the first stage.

In many of this kind of processes foaming is a big problem, which carries away lot of suspended particles in the condensate water, which eventually increases the BOD of distillate. Our technology has taken care of this problem and the BOD levels are contained to an extent of 80 mg/l and the distillate produced is colorless and is reusable for other processes.

Key features (General):
· ZERO Liquid Discharge
· Low Operating Cost
· User Friendly

Zero liquid discharge system (ETP) for grain based distilleries (DDGS plant)
GTE Ltd has designed and supplied DDGS plants to various parties in Africa. In today’s business scenario it is imperative for one to address his attention on the economic and environmental aspects that concern the grain-based alcohol producing industries in Africa vis-à-vis processing of stillage obtained as the by-product after distillation.

Gte Ltd is the pioneer in Africa to have indigenously developed a proven, fully integrated technology for manufacturing Distillers Dried Grains with Solubles (DDGS) from whole grain stillage which is the residue obtained after alcohol has been separated by distillation of the fermented mash of feed stock and water.

Scheme for zero liquid discharge system ( etp ) for grain based distilleries :
The zero discharge system for grain based distillery effluent handling (DDGS Plant) consists of following main processes.
· Decantation System: To separate the suspended particles and thin liquor.
· Evaporation System: To concentrate the thin liquor in vacuum evaporator.
· Mixing & Blending System: To mix the Wet cake and the concentrate.
· Spin Flash Drying: To dry the mix to get dried powder (DDGS).

The Process (DDGS):
The grain stillage from the bottom of analyzer column of grain based distillery is introduced to a continuous decanter centrifuge. Suspended particles are separated as a wet cake from the decanter and thin liquor is further processed to the evaporation section.

The thin liquor from decanter is concentrated in multiple effects falling film vacuum evaporator to get maximum water evaporation per kg steam energy supplied. The total process is under vacuum and the vapours generated in the system are re-used to economize steam consumption. In order to reduce steam consumption in multiple effect evaporation system the thermal vapour recompression system is used. The thermal vapour recompression system use vapours generated in the evaporator and compress it by steam and the compressed vapours are used as heating medium in the evaporator. The concentrate obtained from the evaporator is stored and fed to the mixing section. The wet cake and the concentrate is mixed and blended to for a uniform mix. The so formed mix is fed to the spin flash dryer to dry the wet mix to get dried powder DDGS. Fraction of DDGS at 10% moisture content is re-circulated through the blending section so to reduce the water evaporation load on spin flash dryer.

The DDGS thus obtained is a high protein content product and can be used as cattle feed of good nutritional value.

Effluent treatment plant for textile dyeing industry

ETC system for textile dyeing industries

Textile dyeing industries need huge quantity of water for textile dyeing, which they normally pump out repeatedly from the ground or natural water sources resulting in depletion of ground water level.

In the dyeing process textile industries generate huge quantity of toxic effluent containing colours, sodium sulphate, sodium chloride, sodium hydroxide and traces of other salts. These are generated after dyeing and after washing of garments / fabrics. After dyeing the waste water produced is called Dye Bath water and after washing the waste water generated is called wash water. Dye Bath contains higher solids in the range 4-5% whereas wash water contains only 0.5-1% solids.

Based on the above mentioned fact Gte Ltd has developed a technology which can process such harmful toxic effluent water and transform it into reusable water. Thus the textile industries will have the advantage of using the same water in the dying process repeatedly; also the salt used for dyeing can be reused or sold in the market.

The technology offered by Gte Ltd can overcome all problems pertaining to environmental pollution in respect to textile dying industries.

The basic thrust of the technology is to convert entire quantity of effluent to zero level by separating water and salt using evaporation and separation technology.
The concept and the treatment are based on the removal of the entire COD/BOD and the condensate coming out to meet the fresh water quality requirement in the process.

Textile waste water handling by evaporation and solid separation basic principle:
The technology is based on basic principle of reduction of quantity by concentrating the effluent and subsequently separation of salt and water.

The evaporation process:
Textile Effluent is fed to the vacuum evaporator to concentrate up to 40% solids concentration. The total process is under vacuum and the vapors generated in the system are re-used to economize steam consumption in multiple effect evaporation system with thermal vapour recompression system. The thermal vapour recompression system use Vapours generated in the evaporator and compress it by steam and the compressed vapours are used as heating medium in the evaporator, in this way steam consumption is reduced. Water recovered from the evaporator has low COD/BOD value and can be recycled in the plant.

The resultant slurry (concentrate) is fed to the thickener and centrifuging section for converting the liquid concentrate to solid waste. The mother liquor from thickener and centrifuge is recycled back to evaporator.

The water separated out from evaporator is good enough in quality to recycle in the plant for Dyeing.

Effluent treatment solutions for pharmaceutical & bulk drug industries

Pharmaceutical and bulk drug industries emanate effluent which consists of high organic contents with high COD. Gte Ltd has developed a system to treat such effluent, through evaporation & drying technology & by removing the solvent from High COD stream, using stripper column. With the help of this technology, effluent concentrate is dried to a baggable powder with 6 -8% moisture content, which can be reused as a land filling / disposal.

Process description:
For the purpose of treating this effluent, Evaporation and Drying methods are used. A combination of Industrial Evaporators like Falling Film Evaporator, Forced Circulation Evaporator and the Industrial Dryers like Vertical Thin Film Dryer are used. Other auxiliary techniques such as centrifuging, filtration, incineration are also employed depending upon the characteristics of the effluent.
The effluent containing high amount of organics is heated in a reboiler and passed through a Stripper Column to strip off the maximum low boiling organic solvents and their vapours are condensed using a condenser. These condensed vapours are partially refluxed back to the stripper to enrich the column and rest of the condensate (solvent) is collected separately and can be incinerated in an incinerator for making the facility a complete zero pollution plant.

The output liquid stream from the bottom of the Stripper Column which is now almost free of low boiling solvents enters the Multiple Effect Falling Film Evaporator /forced circulation evaporator or combination of two for further concentration. After concentration in the Evaporator, we get a concentrated stream of effluent which can be then further concentrated or dried in different types of evaporators and dryers depending upon the actual composition of the individual stream. The condensate water obtained from the Falling Film Evaporator is of very low COD. In case further reduction in COD is desired, then various techniques can be used like activated carbon treatment or aeration with a high pressure blower for prolonged periods.

Finally, the whole of the effluent is converted into solid/sludge form so that it can be disposed using various ways like land filling.

Gte Ltd strong background and its research team at the Research & Development Centre tried and tested various techniques to bring down the COD of this condensate water so that it can be used back in the industry/ discharged with COD limits well within the range as specified by the Pollution Control Boards.

Zero liquid discharge effluent treatment solution for black liquor from pulp & paper industries
In pulp mills spent liquor produced during washing of pulp after cooking with Caustic is highly toxic and this cannot be discharged. So its treatment in recovery plant is must. Valuable inorganic chemicals recovery is also done to keep pulping cost under control.

Recovering inorganic chemicals is possible only by incineration of black liquor but since the liquor is in very dilute form containing as low as 8 to 10% solids, it is not economical to incinerate directly. For burning this liquor, it is evaporated in Multiple Effect Evaporator to the desired concentration i.e. 48% in case of conventional recovery or 25 % in case of non conventional systems and then subsequently incinerated.

In case of conventional method of recovery, inorganic chemicals are collected in molten form named smelt. The smelt when dissolved in hot water becomes green liquor which is nothing but maximum sodium carbonate. This Green Liquor is further treated with lime to produce sodium hydroxide which is reused in pulp mill for pulping fibrous raw materials.

In case of non-conventional method of recovery, liquor at 25% TS is further concentrated to 50 % in direct contact flue gas evaporator and burnt in fluidized bed reactor in which inorganic chemicals are recovered at pre-melting stage in the form of soda ash pellets which are sold in the market.

This is how pollution abatement and inorganic chemical recovery is achieved in pulp and paper industries.

Key features:
· Zero Liquid Discharge System.
· Produce Black Liquor Concentrate.
· Highly Energy Efficient (Evaporates 7 Kg of water / kg of steam for concentration upto 50% in Seven Effect Evaporator).
· Minimum Space requirement.
· Fully Customized Design System.
· Low Operating Cost.
· Less Downtime for Maintenance.
· Operator friendly.

Dye / dye intermediates industries
The effluent from the dye/dye intermediate industries containing a mix of organic and inorganic salts is treated using Evaporation and Drying Technology to separate the organic and inorganic salts. The organic salts are used as a solid fuel and the inorganic salt can be a marketable product. The scheme shown above depicts that the effluent is crystallized at first and after centrifuging, the concentrate from the centrifuge comprising organic salts is concentrated using evaporator and then the concentrate is dried using the Agitated Thin Film Dryer or Spray Dryer.

On the other hand, the inorganic salts obtained after centrifuging are melted and treated with Activated Carbon. After separation of carbon from the slurry, the resulting slurry is concentrated using an Evaporator. The concentrate from this evaporator is passed through Centrifuge to obtain inorganic salts with high purity. The salt obtained from the centrifuge now can be dried using a Fluidized Bed Dryer

Electroplating Industries
The effluent from the Electroplating Industries is generally low in solids content and contains metals like chromium and manganese in the effluent.

The effluent is preheated and then fed to the Multiple Effect Falling Film Evaporator for concentration. After concentration, the concentrate is dried using an Agitated Thin Film Dryer. This dried powder can be used as solid waste disposal or as a land fill.

The condensate obtained from the evaporator is clean and colourless liquid and it can be used back in the plant as soft water.

Detergent powder projects
detergent powder plant

Synthetic detergents, which are also known as syndets, were developed to overcome the difficulties faced while using soap as a cleaning agent. Soaps when used in hard water precipitate the calcium and magnesium salts, due to its effectiveness as a cleaning agent deteriorates. In addition, edible oil & fats which could be put to other uses are used as raw materials for the manufacture of soaps. These problems are circumvented in synthetic detergents that are highly stable in hard water and do not consume valuable and expensive oil for their manufacture.

Gelatine processing plant
(Edible / Industrial / Pharma)
Gelatine is derived from Degreased Crushed Bones (DCB) through acid treatment followed by alkaline process. DCB are first treated with acid for removal of inorganic salts in bone. The bones after acid treatment are referred to as Ossein.

Ossein is then treated with alkali for partial hydrolysis. During the partial hydrolysis, the collagen material is softened from the non-collagen. Non-Collagen gets removed with weak alkali solution. The temperature is controlled during maceration and liming to avoid any yield losses. Limed Ossein is then washed with water and then treated with dilute solution of weak acid. Ossein after weak acid treatment is taken for Gelatine extraction.

Gelatine is extracted in the form of weak liquor, which is then filtered and passed through ion exchange (deashing system) for reduction of the dissolved ash(dissolved minerals) in the gelatine solution. This de-ionized weak liquor of Gelatine is then concentrated under vacuum to avoid any destruction to the basic tri skeleton structure of gelatine. So our gelatine processing plant or gelatine extraction plant is very useful.

Concentrated liquor is then passed through sterilization system followed by extrusion for making noodles to facilitate proper drying of Gelatine in the next stage.

Gelatine drying is very critical process since fast heating will melt the gelatine instead of drying and slow drying will result in gelatine moisture out of limits so Gelatine is dried very carefully with dehumidified air by gradual increase of temperature gradually to 60OC.

Dried Gelatine is then crushed to required mesh size as per the market demand. During Gelatine manufacturing DCP is produced as a byproduct. Which is a main constituent for the cattle and poultry feed.

Herbal extraction plant
All the plants / herbs have very complex structure. Most of the active ingredients are present in the form of natural organic compounds.

The process of extraction for a particular compound or multiple compounds are dependent on the solubility of the rich components in an extraction media such as aqua (water) or organic solvent or a mixture of organic solvents by using the principle of physical separation and the property of solubility of those compounds in that particular extraction media.

The process and the plant design of extraction system is invariably different from product to product and component to component. It’s very difficult to generalize a process to extract isolated compounds from various herbs. From raw material to isolated compound, a series of processes will be involved. In the first step of process, the rich compound(s) can be extracted in a generalized manner with an extraction media. The second stage is followed by purification and isolation by various physical / chemical processes.

From a generalized extraction process, the rich herbal extracts can be used directly in herbal formulations for herbal, pharmaceuticals, food and cosmetic industries. Some of the herbal extracts can be used as natural dyes for textile, leather, food and cosmetic applications as coloring matters.

Forced circulation evaporator
This is ideal for concentration of high viscous material and products with higher solids. This is also used as evaporative crystallizer. Sometimes these are used in series with falling film evaporator as finishing effect for achieving higher concentration. In this type of evaporator, liquid is pumped through heat exchanger tubes at high velocity (1.5-4.0 m/s) avoiding precipitation and creating high turbulence; liquid is then passed through vapour separator for separation of vapour and finally condensing the vapour in the condenser. Concentrated liquid is continuously discharged from bottom of vapour separator.

· Brine evaporation (Vacuum Salt processing)
· Effluent concentration with High suspended solid.
· Fruits Pulp Concentration
· Tomato Paste
· Sodium Sulphate Crystallization.

Rising Film Evaporator
In a Rising Film Evaporator liquid feed enters from the bottom of steam heated tubes. The parallel movement of liquid and vapor along tube surface imparts effective water evaporation from the liquid feed. This type of evaporator is ideal for liquids which attain high viscosity or have fouling tendency.

· Fruit Juice concentration.
· Sugar Cane Juice Concentration

Agitated Thin Film Evaporator
The agitated thin film evaporator is well suited for concentration of viscous and heat sensitive liquids such as gelatin, antibiotics, fruit juices, and solvent mix etc. The thin film evaporator reduces fouling and liquid residence time in the evaporator. In the vertical agitated thin film evaporator feed liquid is feed at the top of evaporator and is uniformly distributed in the form of thin film by the wiper blades on vertical cylindrical heat transfer area, inside the unit. Evaporation of water / solvent takes place as the thin film moves down the heat transfer area.

Scrapped Surface / Thin Film Evaporator
Scrapped Surface/Thin Film Evaporator is designed for evaporation of highly viscous and sticky products, which cannot be otherwise evaporated. These types of evaporators have been specially designed to provide high degree of agitation, effecting heat transfer as well as scrapping the walls of the evaporator to prevent deposition and subsequent charring of the product.

Vapour Recompression System (Tvr & Mvr)
The vapour is compressed to higher condensation pressure by means of either Thermal Vapour Recompressor (TVR) or Mechanical Vapour Recompressor (MVR), which results in steam economy. In TVR portion of vapour discharged from one effect is sucked and compressed using motive steam and the resulting mixture is used as a heating medium to bring down the specific steam consumption. In MVR the vapour is recompressed by using two stage compressors with mechanical seals. A typical five effect plant with TVR over three effects has a sp. Steam consumption of 0.12. & a seven effect plant with TVR having vapour suction from 4th effect has a specific steam consumption of 0.09

Freeze Dryer
Industrial freeze dryer retains aroma, improves appearance and taste because freeze drying takes place at a low temperature which minimizes heat damage and retains volatile components (aroma). It also increases the shelf life of the dried product as compared to standard drying practices. Freeze-drying involves dehydration of food products at low temperature and pressure. As a result, only the moisture is removed, leaving the molecular structure intact. The end product is light in weight with least or no change in volume. Worldwide freeze-drying technology is considered as the ultimate amongst all other dehydration methods. Hence this technique is currently being used for the production of instant coffee, instant tea, fruit pulp and other heat sensitive products.

Spin Flash Dryer
Spin Flash Dryer is ideal for drying of wet cake, slurry, paste which is normally difficult to dry in other dryers. The material is fed by screw feeder through a variable speed drive into the vertical drying chamber where it is heated by hot air and at the same time disintegrated by a specially designed disintegrator. The heating of air may be direct or indirect depending upon the application. The dry powder is collected through cyclone separator / bag filter or with combination of both.
