Screw Film Evaporator

Screw Film Evaporator

       I. Overview
Screw blade film evaporators utilize high-speed rotation to distribute liquids into a uniform film for evaporation or distillation. They can also be used for deodorization, degassing reactions, as well as heating and cooling unit operations. Suitable for industries such as food, light industry, petrochemicals, environmental protection, and more.
 

       II. Performance & Features
This equipment features a centrifugal sliding groove rotor, which can form a thin film even at low flow rates. The adhered sediment in the inner wall surface of the drum evaporation section can be quickly removed by the moving scraper. Compared to a scraper evaporator with fixed gaps, the evaporation capacity can be increased by 40-69%. It boasts the following performance and features:
1. High thermal conductivity, large evaporation capacity, with evaporation intensity up to 200 kg/m²·hr, and high thermal efficiency.
2. Short material heating time, approximately 5 to 10 seconds, and operates under vacuum, which is beneficial for heat-sensitive materials. It ensures that all components remain undecomposed, guaranteeing product quality.
3. Wide range of viscosity adaptability, 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 section cylinder has been 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 automatically carry out continuous production.
7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
