Food And Biotech Engineers (India) Private Limited

• Uniform drying with high vacuum.
• Control of residual solvent.

• Best option for large extraction capacities.
• Based on solid- liquid mixing hence high rate of mass- transfer is available.
• Recovery of solvent is done with indirect steam heating.
• Less manual handling is required for discharge of exhausted materials.
• Suitable for GMP

• Forced recirculation evaporator is most suitable evaporator to concentrate the product up to 55-65% total solids, whereas falling film evaporator is suitable to concentrate only 45-48% Total solids.
• Forced recirculation evaporator can be run for 30-40 days without any scaling, whereas falling film evaporator can only be run for 20 hrs only. 4 hours are required to clean the falling film evaporator daily.
• Cleaning shall be required after 30 to 40 days of continuous running of the forced recirculation plant, so there is saving of chemicals, steam and power consumption used for cleaning. Where as cleaning of falling film is required on daily basis for 4 hours, so there will be extra cost for chemicals, steam and power.
• In forced recirculation evaporator, capacity of the plant is designed at lower side with respect to falling film evaporator.
• Despite of having high power consumption in forced recirculation evaporator, processing cost per lit of distillery effluent is less than falling film evaporator.

• Liquid distribution is through distributor plates placed at top of calandria.
• The film is going with gravity.
• Thinner film formation throughout the tubes.
• Shorter product contact time.
• Concentration of highly-sensitive materials.
• Can be operated at much lower del T.
• The lower del T is favorable to vapor recompression and consequently the energy consumption is low.
• Concentration level can be achieved upto 45% TS.
• Useful for the concentration of milk, fuit juice, malt etc.

• Adjustable and controllable direct contact heat treatment units.
• Shortest possible residence time
• Special design to prevent bacteriological growth including thermophiles.
• Special design of liquid distribution systems to ensure correct tube coverage
• Extended tube length
• Efficient design of separators

• Continuous operation brings down the solvent consumption.
• Maximum extraction efficiency
• No emulsion problem

• Purification of high valve compounds using flash chromatography.
• Resin application for isolation of active principles.

• Liquid circulated at high rate through the calandria.
• Higher coefficients are obtained.
• Boiling being prevented within the unit by virtue of a hydrostatic head maintained above the top tube plate. As the liquid enters the separator where the absolute pressure is slightly less than in the tube bundle, the liquid flashes to form a vapor.
• Since the velocity of flashing is very high, impingement deflector/ baffles are important to minimize entrainment.
• Liquid returns to the pump inlet from Vapor separator and meets incoming feed, vapor leave the top of evaporator body to a condenser, part of the liquid leaving the separator is continuously withdrawn as concentrate.
• Require large circulating pumps.
• The concentration level can be achieved upto 65 % TS.
• Useful for concentration of inversely soluble material or for material which is susceptible to scaling or crystallizing like distillery effluent, mango/tomato juice, Malt concentrate (70% TS).

• Malt mix slurry
• Tomato paste
• Mango pulp paste
• Sugar Syrup
• Glucose
• Black
• Distillery effluent
• The concentrate upto 70% TS.

• High heat transfer co-efficient.
• Suitable for medium solid concentration.

• Most suitable for heat sensitive materials.
• Least residence time in heating one.
• Avoid over heating of the products.
• Inter cooler causes immediate condensation of vapor hence no deterioration of distillate.
