Scraper Ttype Film Evaporator
The scraper thin film evaporator is a type of evaporation and distillation equipment that uses high-speed rotation to distribute liquid into a uniform thin film for evaporation or distillation. It can also perform unit operations such as deodorization, defoaming reactions, heating, and cooling. It is suitable for In Chinese and Western pharmaceutical, food, light industry, petroleum, chemical and other industries.
This equipment adopts a centrifugal sliding groove rotor, which can form a thin film even when the flow rate is very small. The sludge in the treatment liquid attached to the inner wall surface of the cylinder evaporation section 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:
- High heat transfer coefficient, large evaporation capacity, and evaporation intensity can reach 200KG/M2`HR , high thermal efficiency.
- The material heating time is short, about 5 seconds to 10 seconds, and it works under vacuum conditions, which is beneficial to heat-sensitive materials. It keeps various components from decomposing and ensures product quality.
- It can adapt to a wide range of viscosity changes and can handle both high and low viscosity materials. The material viscosity can be as high as 100,000 centipoise (CP).
- Changing the rotation direction of the scraper groove can adjust the processing time of the material in the evaporator.
- The inner wall of the evaporation section cylinder has been precision bored and polished, and the surface is not prone to coking and scaling.
- It is easy to operate and adjust product indicators easily. Under closed conditions, continuous production can be carried out under automatic control.
- The equipment occupies a small area, has a simple structure, is easy to maintain and clean.
