Screw-Type Film Evaporator

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 operations. They are suitable for industries such as food, light industry, petroleum, and chemical engineering.

Performance & Features

This equipment features a centrifugal sliding groove rotor, which can form a film even at low flow rates. The adhered sediments in the treatment liquid on the inner surface of the drum's evaporative section can be quickly removed by the moving scraper. Compared to a fixed gap scraper evaporator, the evaporation capacity can be increased by 40-69%. It possesses the following performance and features:

1. 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. Ensures no decomposition of various components, guaranteeing product quality.

3. Wide adaptability to viscosity range, 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 evaporation section cylinder has been precisely bored and polished, making the surface less prone to scaling and fouling.

6. Easy to operate, with simple adjustment of product specifications. Under sealed conditions, it can perform continuous production with self-control.

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