Centrifugal scraper type film evaporator

Online Inquiry

Scraper type film evaporator is a kind of high-efficiency evaporation and distillation equipment that uses high-speed rotation to distribute liquid into uniform film for evaporation or distillation, and can also carry out deodorization, defoaming reaction and heating, cooling and other unit operations, which can be widely used in Chinese and western pharmaceutical, food, light industry, petroleum, chemical, environmental protection and other industries.

The centrifugal scraper film evaporator adopts advanced technology from abroad and has the leading position of international level in the field of domestic scraper film evaporator. This equipment has been used as the host of "scraper type vacuum refining unit" and won the third prize of scientific and technological progress of National Pharmaceutical Administration.

Performance and characteristics

This equipment adopts centrifugal sliding groove rotor, which is the latest structure evaporator abroad, and it can form film even under the condition of very small flow, and the silt in the treatment liquid attached to the inner wall surface of the evaporation section of the cylinder can be quickly removed by the movable scraper, and the evaporation volume can be increased by 40-69% compared with the fixed gap scraper evaporator.

1、High value of heat transfer coefficient, large evaporation capacity, evaporation intensity can reach 200kg/m2-hr, high thermal efficiency.

2、The heating time of material is short, about 5 seconds to 10 seconds, and it works under vacuum condition, which is more favorable to heat-sensitive material, keeping all kinds of ingredients without any decomposition and ensuring product quality.

3、Adapt to the viscosity changes in a wide range, high and low viscosity materials can be handled, material viscosity can be as high as 100,000 centipoise (CP)

4、Change the direction of rotation of the scraper groove, can adjust the material in the evaporator to take care of time.

5、The evaporation section barrel inner wall has been precision boring and polishing treatment, the surface is not easy to produce coking and scaling.

6、Convenient operation, easy to adjust the product index, under the closed condition, it can be self-controlled for continuous production.

7、The equipment covers an area of small, simple structure, convenient maintenance and easy cleaning.
