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, petroleum, chemicals, and more.

Performance and Features
  This equipment utilizes a centrifugal sliding groove rotor, which can form a film even at very low flow rates. The accumulation in the treatment fluid on the inner wall 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 rate can be increased by 40-69%. It possesses the following performance and features:
1. High thermal conductivity value, large evaporation capacity, with evaporation intensity up to 200 kg/m²·hr, and high thermal efficiency.
2. Short material heating time of approximately 5 to 10 seconds, operating under vacuum, benefits heat-sensitive materials by preventing any decomposition of various components, ensuring 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 evaporator tube body is 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. The equipment has a small footprint, a simple structure, easy maintenance, and is easy to clean.
