  • With inside rotary scraping film device, the raw material can be forced into film continuously and uniformly. The rotary thin film evaporator is similar to falling film evaporation under high vacuum conditions. For the heat sensitive material evaporation and concentration, distillation and purification, Rotary film evaporator can avoid bad product quality by long time; improve the evaporation efficiency.

    The material first enters the rotating distribution plate, and the distribution plate will distribute the raw material evenly to the vertical cylinder heating surface. The material will decline by gravity , at the same time, the raw material will be scraped into film evenly by rotating scraping device. The vaporized light component steam goes up and condenses from the upper outlet into condenser, while the non-evaporated portion is discharged from the bottom of the agitated thin film dryer.

    Main features of performance:

    • Open scraper system, small pressure drop
    • High heat transfer coefficient and higher evaporation efficiency
    • Short heating time, low evaporation temperature
    • Have strong adaptability, flexible operation

    Main features of structure:

    • High precision transmission and mechanical seal design, to ensure the smooth operation for long time
    • Processed by whole evaporating cylinder molding, without intermediate flange connection;
    • The cylinder surface is much smooth and clean, no easy to paste. Degree of smoothness for fine grinding surface can reach up to Ra0.8μm; Degree of smoothness for special polishing surface can reach up to Ra0.2μm;
    • With unique demister structure, can effectively prevent the steam entrainment;
    • Bottom scraper structure, much better for discharge of high viscosity materials;

    Applications of agitated thin film evaporator:

    Mainly used for Evaporative concentration, dissolving, stripping, reaction, degassing, deodorization (gas) taste of heat sensitive materials and easily oxidized material. It has been widely used in the fields of medicine, pesticide, oil chemical industry, petroleum chemical industry, fine chemical industry, daily use chemical, biological industry and so on.

    It can replace conventional falling film evaporator, which is used for distillation, purification, concentration and decolorization of petrochemical and chemical products.
