1. Material be heated in short time
Rotating scraper push the material on the heating surface and the material liquid spiraling continuously moves down and escape from the heating surface, the material which is separated escape from the heating surface was quickly collected by condenser cooling, this method has to minimize the contact time of material and heating surface.
Successfully eliminates the thermal decomposition, polymerization, or metamorphic.
2. Low evaporation temperature
Compared with conventional distillation, short path distillation apparatus through material liquid distributor and rotating scraper to make material be uniform distribution on the heating surface, reducing the pressure difference which is generated on material static liquid surface.
Heating surface and condensation surface distance is short, light molecules escape from the heating surface then quickly condensation, reducing the pressure drop during gas transfer, which is more likely to achieve low evaporation pressure.
As long as the light molecular movement free path is greater than the distance from the evaporation surface to the condensation surface, then material can be separated, and material don't need be heated to boiling point, thus the distillation temperature was much lower than the conventional distillation method.
3. Self-cleaning heating surface
Rotating scraper sliding in the heating surface, the liquid film constant agitation and updates, to prevent the material in the heating surface bubble, scraping wall scaling, etc.
It can successfully be applied to the material consentration and separation which is easily bubble, in the heating surface fouling in conventional distillation.
4. High efficiency evaporation, strong adaptability, easy operation
Rotating scraper makes the material be uniform distributed on heating surface as a film, the liquid film always maintain high turbulence state, which accelerates the heat transfer to reduce the heat loss.
Simple structure, convenient cleaning, freedom of start-up and shut-down, suitable for many varieties, discontinuous small chemical production.
