Scraper thin-film evaporator

■ ZGB type rotating scraper film evaporator, by rotating scraper is forced into a membrane, can be falling film evaporation under vacuum conditions in a new type of high efficiency evaporator, its heat transfer coefficient is big, high evaporation strength, flow time is short, large elasticity of operation, especially suitable for heat-sensitive material, high viscosity material and crystallizable materials including particle evaporation concentration, degassing desolventizing, distillation purification. Therefore, in the chemical, pharmaceutical, food, chemical and other industries widely used.
 

Performance and features
■ this evaporator USES centrifugal rotor of the sliding groove, is currently the foreign latest evaporator structure, under the condition of the traffic is very small also can form a thin film, evaporation in simplified the vicinity of well-bore can be adhered on the surface of the wall treatment fluid activity scraper removed rapidly, and compared to fixed clearance scraper evaporator, evaporation can increase 40-69%, it has the following properties and features:
1. Heat transfer coefficient value is high, the evaporation capacity is big, the evaporation intensity can reach 200 kg/m2, hr, high thermal efficiency.
2. To adapt to changes in viscosity range, both high and low viscosity can be processing, material secco 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. Easy to operate, product indicators to adjust easily, in an airtight conditions, can be continuous automatic production.
7. The evaporator cover an area of an area small, simple structure, convenient maintenance, easy washing.
