Product Overview
Screw blade film evaporators are a type of evaporation and distillation equipment that uses 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. They are widely applicable in industries such as food, light industry, petrochemical, and chemical industries.

Performance and Features
This equipment features a centrifugal sliding groove rotor, which can form a film even at low flow rates. The adhered sediment in the wall surface of the drum evaporation 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 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. Material heating time is short, approximately 5 to 10 seconds, and operates under vacuum, benefiting heat-sensitive materials. It ensures that various components do not decompose, guaranteeing product quality.
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 evaporator section cylinder has been 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 automatically control continuous production.
7. Compact footprint, simple structure, easy maintenance, and effortless cleaning.
