Molecular distillation is a special liquid-liquid separation equipment. Unlike traditional distillation, it relies on the boiling point difference separation principle, but on the difference of the average free path of different substances. When the liquid mixture flows along the inner wall of the main evaporator and is heated, light and heavy molecules will escape from the liquid level and enter the gas phase. Due to the different free paths of light and heavy molecules, the molecules of different substances move different distances after escaping from the liquid level. After passing through the built-in condensate pipe of the main evaporator, the light molecules reach the condensate pipe and are discharged, while the heavy molecules cannot reach the condensate pipe and are discharged along the mixed liquid, So as to achieve the purpose of material separation.
The materials are transported from the feed tank to the jacketed main evaporator. The main evaporator is continuously heated. The built-in scraper evenly scrapes the materials into a layer of flowing liquid film for instant evaporation. The light component materials begin to vaporize and adsorb on the built-in condensing coil, flow into the receiving bottle along the outer wall of the condensing pipe, and the heavy component materials flow into the receiving bottle along the inner wall of the main evaporator.
