Screw Film Evaporator

Product Overview

Screw-plate film evaporators utilize high-speed rotation to distribute liquids into a uniform film for evaporation or distillation. They are also capable of deodorization, de-bubbling reactions, and unit operations such as heating and cooling. These are suitable for industries including food, light industry, petroleum, and chemical engineering.

Performance and Features

This equipment utilizes a centrifugal sliding groove rotor, capable of forming a film even at low flow rates. The adhered sediments in the wall 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 value, large evaporation capacity, with evaporation intensity up to 200KG/M2·HR, and high thermal efficiency.

2. Material heating time is short, approximately 5 to 10 seconds, and operates under vacuum conditions, benefiting heat-sensitive materials. It ensures that various components do not decompose, thereby guaranteeing product quality.

3. Wide range of viscosity adaptability; can handle 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 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. Under sealed conditions, it can self-regulate for continuous production.

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