Rotary film evaporator
Scraper type thin film evaporator is an efficient 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 deodorization, defoaming reactions, heating, cooling and other unit operations, and can be widely used in industries such as pharmaceuticals, food, light industry, petroleum, chemical industry, and environmental protection in China and the West.
This equipment adopts a centrifugal sliding groove rotor, which is a new structure evaporator in foreign countries. It can form a thin film even at very low flow rates. The sediment 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 cofficient value, large evaporation capacity, evaporation intensity can reach 200kg/m2. hr, and high thermal efficiency.
- The heating time of the material is short, about 5 to 10 seconds, and it works under vacuum conditions, which is more advantageous for heat sensitive materials, keeping various components from decomposing and ensuring product quality.
- It can adapt to a wide range of viscosity changes and handle both high and low viscosity materials. The material viscosity can reach up to 100000 centipoise (CP).
- Changing the rotation direction of the scraper groove can adjust the maintenance time of the material in the evaporator.
- The inner wall of the evaporation section cylinder is precision bored and polished, making the surface less prone to coking and scaling.
- Easy to operate, easy to adjust product indicators, and can be controlled for continuous production under closed conditions.
- The equipment has a small footprint, simple structure, easy maintenance, and easy cleaning.
