Products Description

Wiped film molecular still differs from traditional distillation by the principle of separation of boiling points, but by the difference in the mean free path of molecular motion of different substances.

 

Using the working principle of molecular distillation, our wiped film molecular still are highly efficient plant essential oil purification equipment for high purity essential oils.

working principle

molecular distillation unit

The separation process is as shown in the figure. The material is added from the top of the evaporator and distributed continuously and uniformly on the heating surface through the material-liquid distributor. The film scraper scrapes the product into a very thin, turbulent liquid film. In this process, the light molecules escaping from the heating surface reach the condenser and condense into liquid, and flow down the condenser tube, and discharge through the discharge tube at the bottom of the evaporator; Residues, or heavy molecules, are collected in a circular channel under the heating zone and then discharged through a side discharge tube.
