Scraper Film Evaporator
Product Overview
Screw blade 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 are also capable of deodorization, degassing reactions, as well as heating and cooling unit operations. They are widely applicable in industries such as food, light industry, petrochemical, environmental protection, and more.
Performance and Features
This equipment utilizes a centrifugal sliding groove rotor, which is a new type of evaporator capable of forming a film even at low flow rates. The adhered sediment in the inner wall surface of the cylinder's evaporation section can be quickly removed by the movable 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:
High thermal conductivity value, large evaporation capacity, with evaporation intensity reaching 200kg/m²·hr, and high thermal efficiency.
2. Short material heating time, approximately 5 to 10 seconds, and operates under vacuum, which is beneficial for heat-sensitive materials, preventing decomposition of various components and ensuring product quality.
3. Wide range of adaptability to viscosity changes, 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, with simple product specification adjustments. Under sealed 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.
