Glass Wiped Film Molecular Distillation Equipment

Molecular distillation is a special liquid-liquid separation technology, which is different from traditional distillation which relies on the principle of boiling point difference separation. This is a process of distillation and purification of heat-sensitive material or high boiling points material using the difference in the free path of molecular motion under high vacuum. Mainly used in chemical, pharmaceutical, petrochemical, spices, plastics and oil and other industrial fields.

The material is transferred from the feeding vessel to the main distillation jacketed evaporator. Through the rotation of the rotor and continuous heating, the material liquid is scrape into an extremely thin, turbulent liquid film, and pushed downward in a spiral shape. In the process of descent, the lighter material (with low boiling point) in the material liquid begins to vaporize, move to the internal condenser, and become liquid flowing down to the light phase receiving flask. Heavier materials (such as chlorophyll, salts, sugars, waxy, etc.) do not evaporate, instead, it flows along the inner wall of the main evaporator into the heavy phase receiving flask.
