subject: Real Airborne Multi-effect Film Evaporator [print this page] Principle and Application of a Principle and Application of a
Airborne multi-effect film evaporator temperature really is my company for many years on the basis of biochemical engineering practice self-development and design of advanced modern separation unit. The unit is really airborne film evaporation theory, the solution will be diluted to one part of the boiling heat of vaporization of water, so as to achieve the purpose of concentrated solution. With advanced technology, energy consumption, low evaporation temperature, the material and heat transfer surface contact time is short and concentrated than the big, large capacity and so on. The unit uses a continuous crystallization method can produce the heat-sensitive materials to be processed according to the design, can use waste steam as heat source, evaporation can be carried out in the ammonia recovery, thermal efficiency and high degree of automation. Apply to lysine, glutamic acid, organic acid, concentrated sugar processing of agricultural products. Can also be used for fine chemical wastewater treatment.

Structure and performance characteristics of the three
low energy consumption, consumption than evaporation (evaporate 1kg of water need to consume raw steam units KG): Three Four Efficiency 0.28 Efficiency 021 5 0175;
DC-type falling film evaporator, short of materials and steam heat exchanger 30 to-40 seconds;
high vacuum, evaporation temperature is low, the application of evaporation heat sensitive materials;
high degree of automation, small size;
device selection according to the characteristics of materials and customer decisions, and strive to affordable, high quality.
