Centrifugal scraper film evaporator

summary

Centrifugal scraper film evaporator is an efficient evaporation and distillation equipment that uses high-speed rotation to distribute liquid into a uniform film for evaporation or distillation. It can also perform unit operations such as deodorization, defoaming reactions, heating, and cooling,It can be widely applied to industries such as pharmaceuticals, food, light industry, petroleum, chemical, and environmental protection in China and the West.

Performance and characteristics: This equipment adopts a centrifugal sliding groove rotor, which can form a thin film even at low flow rates. The sediment in the treatment liquid attached to the inner wall surface of the evaporation section of the cylinder can be quickly removed by a movable scraper. Compared with a 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 value, large evaporation capacity, evaporation intensity can reach 200kg í m hr, and high thermal efficiency.
2. The heating time of the material is short, about 5 seconds to 10 seconds, and it works under vacuum conditions, which is more advantageous for thermosensitive materials and ensures product quality.

3. It can adapt to a wide range of viscosity changes and handle both high and low viscosity materials, with material viscosity up to 100000 centipoise (CP).
4. Changing the inclination direction of the scraper groove can adjust the processing time of the material in the evaporator.

5. The inner wall of the evaporation section cylinder is precision bored and polished, making the surface less prone to coking and scaling.
6. Easy to operate, easy to adjust product indicators, and can be self controlled for continuous production under closed conditions.
7. The equipment has a small footprint, simple structure, easy maintenance, and easy cleaning.
