Screw Evaporator

Product Overview

Screw blade film evaporators are equipment that utilizes 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, and are suitable for industries such as food, light industry, petroleum, and chemicals.

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 evaporative section can be quickly removed by the movable scraper. Compared to a scraper evaporator with fixed gaps, the evaporation rate 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; 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 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 self-regulate for continuous production.

7. The equipment occupies a small footprint, features a simple structure, is easy to maintain, and clean.
