LG series centrifugal scraper film evaporator

summary
The scraper type film evaporator is a kind of high-efficiency evaporation and distillation equipment which uses high-speed rotation to distribute liquid into uniform film for evaporation or distillation. It can also carry out deodorization, defoaming reaction, heating, cooling and other unit operations. It can be widely used in Chinese and Western medicine, food, light industry, petroleum, chemical industry, environmental protection and other industries.
 
Performance and characteristics
This equipment adopts centrifugal sliding grooved rotor, which is a new structure evaporator abroad. It can form thin film in the case of small flow rate. The deposit in the treatment liquid can be quickly removed by the movable scraper. Compared with the fixed gap scraper evaporator, the evaporation capacity can be increased by 40-69%. It has the following performance and characteristics:
1. High heat transfer coefficient, high evaporation capacity, evaporation intensity of 200kg / m2 · HR and high thermal efficiency.
2. The heating time of materials is short, about 5 seconds to 10 seconds, and working under vacuum conditions is more favorable for heat sensitive materials. It can keep all kinds of components from decomposition and ensure the product quality.
3. It can adapt to a wide range of viscosity changes. High and low viscosity materials can be processed. The viscosity of materials can be as high as 100000 centipoise (CP)
4. Changing the rotation direction of scraper groove can adjust the material handling time in the evaporator.
5. After precision boring and polishing, the inner wall of evaporation section cylinder is not easy to produce coking and scaling.
6. It is easy to operate and adjust the product index. Under the closed condition, the continuous production can be controlled automatically.
7. The equipment covers a small area with simple structure, convenient maintenance and easy cleaning.
