Screw Evaporator

Screw Evaporator

Product Overview
A scraper evaporator is a type of evaporation and distillation equipment that uses high-speed rotation to distribute liquids into a uniform film for evaporation or distillation. It can also perform deodorization, degassing reactions, as well as heating and cooling unit operations. It is suitable for industries such as food, light industry, petroleum, and chemical engineering.

Performance and Features
This equipment utilizes a centrifugal sliding groove rotor, which can form a film even at very low flow rates. The adhered sediments on the inner wall surface of the drum's evaporating section can be quickly removed by the moving scraper. Compared to a fixed gap scraper evaporator, the evaporation capacity can be increased by 40-69%. It features the following performance and characteristics:
1. High thermal conductivity, large evaporation capacity, with evaporation intensity up to 200KG/M2·HR, and high thermal efficiency.
2. Short material heating time, approximately 5 to 10 seconds, and operates under vacuum conditions, benefiting thermally sensitive materials by preventing any decomposition of various components, ensuring product quality.
3. Wide viscosity range adaptation; capable of handling both high and low viscosity materials. Material viscosity can reach up to 100,000 centipoise (CP).
4. Changing the scraper groove rotation direction can adjust the material's residence time in the evaporator.
5. The inner wall of the evaporator tube body is precision bored and polished, making the surface less prone to scaling and fouling.
6. User-friendly operation, easy to adjust product specifications. Under sealed conditions, it can self-regulate for continuous production.
7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
