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 and Features
This equipment features a centrifugal sliding groove rotor, which can form a film even at low flow rates. The adhered sediments on the inner surface of the drum's evaporative section can be quickly removed by the movable scraper. Compared to a scraper evaporator with fixed gaps, the evaporation rate can be increased by 40-69%. It boasts the following performance and features:
1. High thermal conductivity, large evaporation capacity; evaporation intensity can reach 200kg/m²2·HR, high thermal efficiency.
2. Short material heating time of about 5 to 10 seconds, operates under vacuum conditions, benefits heat-sensitive materials, maintains all components without decomposition, ensuring 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 precision bored and polished, making the surface less prone to coking and scaling.
6. Easy to operate, product specifications are easily adjustable; under sealed conditions, it can perform continuous production automatically.
7. The equipment occupies minimal floor space, has a simple structure, is easy to maintain, and can be cleaned effortlessly.
