Latest company news about Scraper film evaporator

Scraper film evaporator is a high-efficiency evaporation and distillation equipment that uses high-speed rotation to distribute liquid into uniform film for evaporation or distillation. It can also carry out unit operations such as deodorization, defoaming reaction, heating and cooling. It can be widely used in Chinese and Western pharmaceutical, food, light industry, petroleum, chemical industry, environmental protection and other industries.
Centrifugal scraper film evaporator adopts foreign advanced technology and has a leading position at the international level in the field of domestic scraper film evaporator.

Performance and characteristics:
This equipment is the latest evaporator in foreign countries. It can also form a film under the condition of small flow. The sediment 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. Compared with the scraper evaporator with fixed gap, the evaporation capacity can be increased by 40-69%. It has the following properties and characteristics:

1. The heat transfer coefficient is high, the evaporation capacity is large, the evaporation intensity can reach 100kg / m2 · HR, and the thermal efficiency is high.
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, so as to keep various components from any decomposition and ensure product quality.
3. It is suitable for a wide range of viscosity changes. High and low viscosity materials can be processed, and the material viscosity can be as high as 100000 centipoise (CP)
4. Changing the rotation direction of the scraper groove can adjust the handling time of the material in the evaporator.
5. The inner wall of the evaporation section cylinder is precisely bored and polished, and the surface is not easy to coke and scale.
6. It is easy to operate and adjust product indexes. Under closed conditions, it can carry out continuous production automatically.
7. The equipment has the advantages of small floor area, simple structure, convenient maintenance and easy cleaning.
