Centrifugal Screw Film Evaporator

Centrifugal Scraped Film Evaporator

Centrifugal Screw Film Evaporator Overview
Screw blade film evaporators are a type of evaporation and distillation equipment that use high-speed rotation to distribute liquids into a uniform film for evaporation or distillation. They can also perform deodorization, degassing reactions, as well as heating and cooling unit operations. They are suitable for industries such as food, light industry, petrochemical, chemical, and environmental protection.

Performance and Features
This equipment utilizes a centrifugal sliding groove rotor, which can form a film even at low flow rates. The sediment in the treatment liquid adhering to the inner surface of the drum's evaporating section can be quickly removed by the movable 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 value, large evaporation capacity, with evaporation intensity up to 200 kg/m³.²· High thermal efficiency.
2. Material heating time is short, approximately 5 to 10 seconds, and operates under vacuum, which is more beneficial for heat-sensitive materials, ensuring no decomposition of any components.
3. Wide range of viscosity adaptability; can handle 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 evaporation section cylinder is precision bored and polished, making the surface less prone to scaling and fouling.
6. Easy to operate, with simple product specification adjustments. Under sealed conditions, it can automatically carry out continuous production.
7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
