Screw Plate Film Evaporator



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

Performance & Features
This equipment features a centrifugal sliding groove rotor, capable of forming a film even at low flow rates. The adhered sludge in the cylinder's evaporative section inner surface can be quickly removed by an adjustable scraper. Compared to a fixed gap scraper evaporator, the evaporation capacity can be increased by 40-69%. It boasts the following performance and characteristics:
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, benefiting heat-sensitive materials. Ensures no decomposition of various components, 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 it resistant to scaling and fouling on the surface.
6. Easy to operate, with simple product parameter adjustments. Under sealed conditions, it can automatically perform continuous production.
7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
