Overview
The scraper-type thin film evaporator is a high-efficiency evaporation and distillation device that uses a high-speed rotation to distribute a liquid into a uniform film for evaporation or distillation. It can also perform unit operations such as deodorization, defoaming reaction, heating and cooling, and can be widely applied to , Western pharmaceutical, food, light industry, petroleum, chemical, environmental protection and other industries.
Centrifugal scraper film evaporator adopts professional technology and has a certain position in the field of domestic scraper thin film evaporator.

Performance and characteristics
The device adopts centrifugal sliding groove rotor, which is a new structure evaporator in foreign countries. It can also form a film when the flow rate is small. The sludge in the treatment liquid attached to the inner wall surface of the evaporation section of the barrel can be moved by the movable scraper. Quickly removed, the evaporation can be increased by 40-69% compared to the fixed gap scraper evaporator, which has the following performance and features:
1. The heat transfer coefficient is high, the evaporation capacity is large, the evaporation strength can reach 200kg/m2·hr, and the thermal efficiency is high.
2. The heating time of the material is short, about 5 seconds to 10 seconds, and it works under vacuum conditions, which is beneficial to the heat sensitive material, keeping the various components from any decomposition and ensuring the product quality.
3, adapt to a wide range of viscosity changes, high and low viscosity materials can be processed, the material viscosity can be as high as 100,000 centipoise (CP).
4. Change the direction of rotation of the scraper groove to adjust the time of the material in the evaporator.
5. The inner wall of the evaporation section cylinder is precision boring and polished, and the surface is not easy to produce coking and scaling.
6, easy to operate, product indicators are easy to adjust, under closed conditions, can be controlled for continuous production.
7. The equipment has small floor space, simple structure, convenient maintenance and easy cleaning.
