Screw Evaporator

Screw 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 perform deodorization, degassing reactions, as well as heating and cooling unit operations, and are suitable for industries such as food, light industry, petrochemicals, 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 moving 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:

1. High thermal conductivity, with a large evaporation capacity, the evaporation intensity can reach 200KG/M2·HR, and high thermal efficiency.

2. Short material heating time, approximately 5 to 10 seconds, and operates under vacuum conditions, benefiting heat-sensitive materials. Ensures no decomposition of various components, guaranteeing 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 direction of the scraper groove rotation 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 adjustment of product specifications. Under sealed conditions, it can perform continuous production automatically.

7. The equipment occupies minimal floor space, has a simple structure, is easy to maintain, and clean.
