Screw Plate Film Evaporator

Product Overview
Screw blade film evaporators utilize high-speed rotation to distribute liquids into a uniform film for evaporation or distillation. They can also perform deodorization, de-bubbling reactions, as well as heating and cooling unit operations. They are widely applicable in industries such as food, light industry, petroleum, chemical, and more.

Performance and Features
This equipment utilizes a centrifugal sliding groove rotor, which can form a thin film even at low flow rates. The sediment in the treatment liquid adhering to the inner surface of the drum's evaporative 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, 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 residence time in the evaporator.
5. The inner wall of the evaporation section cylinder has been precision bored and polished, making it resistant to coking and scaling on the surface.
6. Easy to operate, with simple product parameter adjustments. Under sealed conditions, it can automatically carry out continuous production.
7. The equipment occupies minimal floor space, has a simple structure, is easy to maintain, and clean.
