Screw Blade Film Evaporator

Product Description
Screw plate film evaporators are high-efficiency 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, de-foaming reactions, as well as heating and cooling operations. These are widely applicable in industries such as Chinese and Western pharmaceuticals, food, light industry, petrochemicals, environmental protection, and more.

Performance and Features
This equipment utilizes a centrifugal sliding groove rotor, which can form a film even at low flow rates. The sediment in the treatment liquid adhering to the inner surface of the drum's evaporating 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 features the following performance and characteristics:
1. High thermal conductivity value, large evaporation capacity, with evaporation intensity up to 200 kg/m²·hr, and high thermal efficiency.
2. Material heating time is short, approximately 5 to 10 seconds, and operates under vacuum, benefiting heat-sensitive materials. It ensures that various components do not decompose, guaranteeing product quality.
3. Wide adaptability to viscosity range; 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 handling time in the evaporator.
5. The inner wall of the evaporator section cylinder has been precision bored and polished, making it resistant to scale and fouling buildup.
6. Easy to operate, with simple adjustment of product specifications. Under closed conditions, it can automatically carry out continuous production.
7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
