1. Minimal pressure loss

    In rotating scraper film evaporator, the material flow and the secondary steam flow "are two separate" channel ": the material is along the evaporation of the inner wall of the cylinder (mandatory film-forming) falling film; And by the evaporation surfaceevaporated out of the center of the secondary steam from the cylinder space is virtually unimpeded leaving the evaporator, so that the pressure loss (or pressure drop) is minimal.

    2. can achieve the operation genuine under vacuum conditions

    Precisely because the secondary steam from the evaporation surface to the condenser resistance is minimal, and thus the entire evaporator evaporation surface of the cylinder wall can maintain a high degree of vacuum (up-750mmHg or more), is almost equal to the the export the degree of vacuum of the vacuum system. Due to the improvement of the degree of vacuum, and effectively reduces the boiling point of the material being processed.

    3. high heat transfer coefficient, high evaporation strength

    The boiling point of the reduction of material, increase the temperature difference with the heat medium; the form of a turbulent state of the liquid film, reducing the thermal resistance; Similarly, inhibition of coke material in the wall, scaling, but also improve the tubular wall by evaporation the stars heat transfer coefficient;the the efficient rotary film evaporator heat transfer coefficient up to 8000KJ / h · ㎡ · ℃, evaporation intensity is high.

    4. Low evaporation

    Since the the evaporation cylinder body able to maintain a high degree of vacuum, the boiling point of the material to be processed is significantly reduced, and therefore particularly suitable for low temperature evaporation of the heat-sensitive materials.

    5. Overcurrent short time

    Materials within the evaporator overcurrent time is very short, about soil about 10 seconds, not coke, no scaling; activities scraper, scraping animal feed end diversion trench, which bevel is typically 45 °, to change the angle of the overcurrent time can change the material, the material in the scraping action of the scraper was spiral down leaving the evaporator section. Shortened overcurrent time, effectively preventing the decomposition of the product during the evaporation process, the polymerization or deterioration.
