Applicable scope
The scraper type thin film evaporator is a highly efficient evaporation and distillation apparatus which can be used for the evaporation or distillation of the liquid to form a uniform film by high rotation. It can also be used for deodorization, defoaming reaction, heating and cooling, and can be widely used , Especially in the heat-sensitive materials, high viscosity materials and easy to crystallize with the evaporation of granular materials, degassing and desolvation, distillation and purification.

 

Equipment composition
The equipment consists of motor, reducer, separation Jane, cloth feeder, gas-liquid separator, evaporation of the body, rotor, scraper, the end of the head and other components.

 

Working principle
The material is preheated by the upper part of the evaporator in the tangential direction, due to gravity, centrifugal force and rotary scraper scraping action, the solution in the inner wall of the device to form a spin under the film, and in this process is concentrated by evaporation, Discharge, secondary steam overflow from the top.

 

Main feature
The equipment uses centrifugal sliding groove rotor, is the latest structure of the current evaporator, in the case of very small flow can also form a thin film, in the cylinder evaporation section of the wall surface of the treatment solution attached to the sludge can be moved quickly Removal, compared with the fixed gap of the scraper evaporator, the evaporation can be increased by 40% -69%, it has the following performance and characteristics:
1. High heat transfer coefficient, large evaporation capacity, evaporation intensity can reach 200kg / m2 · h, high thermal efficiency
2. Material heating time is short, about 5 seconds to 10 seconds, and under vacuum conditions work on the heat-sensitive materials more favorable to keep the various components do not produce any decomposition to ensure product quality.
3. Adapt to a wide range of viscosity changes, a high degree of viscosity can be handled, the material viscosity can be as high as 10 cm (CP).
4. Change the direction of rotation of the scraper groove, you can adjust the material in the evaporator processing time asked.

5. Evaporation of the inner wall of the tube through the precision boring and polishing, the surface is not easy to produce coking, scaling.

6. Easy to operate, easy adjustment of product specifications, in a closed condition, you can carry out continuous production.

7. Equipment covers an area of small, simple structure, easy maintenance, easy to clean.
