A . Summary
Scraper film evaporator was used for high speed rotating liquid distribution into uniform thin film evaporation and distillation of a highly efficient evaporation, distillation equipment, can also be used for deodorization, deaeration reaction, heating and cooling unit operations, can be widely applicable to the Chinese and western pharmaceutical, food, light industry, petroleum, chemical industry, environment protection, etc.
Centrifugal scraper membrane evaporator using advanced foreign technology, in the domestic scraper film evaporator area has a leading position in the international level. The device as a "scraper vacuum refining mill unit" host, and won the state drug administration science and technology progress third prize. B . Performance and features
1, high coefficient of heat transfer value, evaporation capacity is big, the evaporation intensity can reach 200 kg/m2, hr, high thermal efficiency.
2 short heating time, material, between about 5 seconds to 10 seconds, and work in a vacuum conditions are more favorable for heat-sensitive materials, keep all kinds of ingredients do not produce any decomposition, ensure the quality of products.
3, to adapt to changes in viscosity range, both high and low viscosity can be processing, material viscosity can be as high as 100000 centipoise (CP)
4, change the scraper groove direction of rotation, can adjust the running time of the material in the evaporator.
5, after evaporation section of cylinder precision boring and polishing processing, surface is not easy to produce coking, scaling.
6, convenient operation, the product index adjustment easy, in an airtight conditions, can be continuous automatic production.
7, equipment cover an area of an area small, simple structure, convenient maintenance, easy washing.
