Screw-Blade Film Evaporator

Product Overview

Screw blade film evaporators are a type of evaporation and distillation equipment that use 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, petrochemical, and chemical industries.

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 wall surface of the cylinder's evaporation 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, 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 conditions, beneficial for heat-sensitive materials, ensuring no decomposition of various components and maintaining 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'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 scaling and fouling.

6. User-friendly operation, easy to adjust product specifications; capable of continuous production under sealed conditions.

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