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 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, capable of forming 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, with a large evaporation capacity, the evaporation intensity can reach 200 kg/m²·hr, and high thermal efficiency.
2. Short material heating time of approximately 5 to 10 seconds, operates under vacuum, benefiting heat-sensitive materials, ensuring no decomposition of various components and maintaining 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 coking and scaling.
6. Easy to operate, with simple adjustment of product specifications. Under sealed conditions, it can autonomously perform continuous production.
7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
