Wiped Film Evaporator

Structure:

1. Feed tank    2. Feed preheater    3. Wiped Film Evaporator    4. Gaseous phase substance    5. Condenser    6. Heavy phase substance    7. Light phase substance

 

Features:

1. Wide adaptability: materials with high viscosity, heat sensitivity, easy to crystallize and scale;

2. High efficiency, large capacity, large evaporation per unit area, evaporation of water and organic solvents and other solutions 80~300Kg/h·m²;

3. The residence time of the material on the evaporation surface is short, about 10 seconds, and it is not easy to coke and scale;

4. It can achieve low-temperature evaporation under high vacuum conditions and save heat source;

5. It can be suitable for automatic continuous production, with large operation flexibility, simple structure, easy maintenance, and automatic control;

6. Change the shape of the scraper (the groove inclination angle on the outside of the scraper) to adjust the time of the material staying in the evaporator to meet the needs of evaporation of materials of different viscosities.

 

Main configurations:

1. Container housings with jacketed or half-tube heating;

2. The rotor can be configured with different scraper forms: movable scraper, fixed scraper, hinged scraper, etc.;

3. The distributor can be evenly distributed with materials;

4. The gas-liquid separator can be entrained by means of mist;

5. Bottom seal head with external or built-in bearing support rotor.
