Screw Film Evaporator

Scraper Film Evaporator

Product Overview

Screw blade thin film evaporators 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. Suitable for industries such as food, light industry, petrochemical, and chemical sectors.

Performance & Features

This equipment utilizes a centrifugal sliding groove rotor, which can form a film even at very low flow rates. The adhered sludge in the internal wall surface of the drum's evaporative section can be rapidly 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, large evaporation capacity, with evaporation intensity up to 200KG/M2·HR, and high thermal efficiency.

2. Short material heating time, 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 range of viscosity adaptability; can handle both high and low viscosity materials, with material viscosity 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 evaporation section cylinder has been precision bored and polished, making the surface less prone to coking and scaling.

6. User-friendly operation, easy to adjust product specifications. Under sealed conditions, it can perform continuous production automatically.

7. The equipment has a small footprint, simple structure, easy maintenance, and convenient cleaning.
