The equipment is an ideal choice for materials that are heat-sensitive, viscous or have a high boiling point, which cannot be processed by conventional distillation.

Main feature:

1. Low-pressure drop is the main advantage of the thin film evaporator: a certain pressure difference is required to transport the evaporated material from the heating surface to the designated condenser in the state of steam. In a typical evaporator, this pressure drop is usually quite high, and sometimes it is too high to be acceptable. However, in the thin film evaporator, the gas has a greater ability to pass through the space, the pressure in the evaporator is almost equal to the pressure in the condenser, and the pressure drop loss is small.

 

2. High vacuum and low evaporation temperature: Due to the low-pressure drop of the thin film evaporator, the evaporation process of the thin film evaporator can be carried out under the conditions of high vacuum and corresponding lower temperature, which is especially suitable for the low-temperature evaporation of heat-sensitive materials.

 

3. Self-cleaning heating surface: thin film evaporator with a scraper. The scraper will slide on the heating surface, so the liquid film is constantly agitated and renewed, which can be successfully applied to the evaporation and evaporation of potentially polluting materials on the heater.

 

4. High overall heat transfer coefficient: Because the thickness of the liquid film on the heating surface is one of the most important parameters to control the overall heat transfer coefficient, it can easily control it by using the continuous contact of the scraper.

 

5. The material flow time is short: the chute on the end face of the scraper pushes the material liquid downward in a spiral shape and continuously leaves the heating surface on the heating surface. Using this method can reduce the residence time and eliminate thermal decomposition. Aggregate or deteriorate. The dwell time can control the dwell time by changing the rotational speed of the rotor or the angle of the scraper slot.

Laboratory vacuum distillation equipment has undergone significant advancements in recent years, driven by the need for higher efficiency, improved safety, and enhanced user experience.
