Detail Description

Equipment Features

Rotary film evaporator possess the following unique advantages, is a conventional film evaporator can not match:

1.Small Pressure LossIn efficient rotary film evaporator, evaporation material flow and the secondary steam flow is two independent channels: evaporation materials along the cylinder wall (mandatory deposition) Falling film down; evaporation surface evaporation by the secondary steam from the center of the cylinder space is almost unhindered leaving the evaporator, so the pressure loss (or pressure drop) is minimal.

2.Can Be True Operation Under Vacuum ConditionsPrecisely because the secondary vapor from the evaporator to the condenser surface resistance is extremely small, so that evaporation of the evaporation surface of the cylinder wall to maintain a high vacuum (up-750mmHg), almost equal to the degree of vacuum in the vacuum system outlet, the vacuum degree increase, effectively reducing the boiling point of the material being processed.

3.High Heat Transfer Coefficient, High Evaporation IntensityThe lower boiling point, increasing the temperature difference between the heat medium; was turbulent liquid film, reducing the thermal resistance; while suppressing coke on the wall material, scale, also improves the evaporation heat transfer coefficient of the tube wall; so high Italian rotary film evaporator heat transfer coefficient can be as high 8000KJ/h.m2℃, so the evaporation intensity is high.

4.Low Temperature EvaporationThe cylinder body due to evaporation to maintain a high vacuum, the boiling point of the material being processed greatly reduced, therefore particularly suitable for low temperature evaporation heat-sensitive materials.

5.Overcurrent Short TimeThe material in the evaporator overcurrent short time, about 10 seconds or so; scraper for common activities, its end face scraping animal materials diversion groove, which angle is generally 45℃change the angle of the angle, can change the material time overcurrent, scrape the material in the squeegee, the downward spiral leaving the evaporator section. Shorter time overcurrent, to effectively prevent product decomposition during the evaporation process, the polymerization or deterioration.

6.Can Use Low-Grade SteamSteam is used for the heat medium, the boiling point of the material due to the reduction in ensuring the same condition △ t, can reduce the temperature of the heating medium, the use of low-grade steam, beneficial utilization of energy.

7.Adaptability, Easy To OperateUnique structural design, so that the product can be difficult to deal with some conventional evaporator handle high viscosity, containing particles, heat-sensitive and easily crystallized materials.Rotary film evaporator operating flexibility, stable operating conditions, and less maintenance, easy maintenance.
