Molecular Distiller
Molecular distillation is a distillation method that operates in a high vacuum, where the mean free path of the vapor molecules is greater than the distance between the evaporating surface and the condensing surface, so that the liquid mixture can be separated by the difference in the evaporation rate of the components in the feed liquid.
Molecular distillation is a special liquid-liquid separation technology, which is different from traditional distillation by the separation principle of boiling point difference, but by the difference of the mean free path of molecular motion of different substances to achieve separation. When the liquid mixture flows along the heating plate and is heated, the light and heavy molecules will escape the liquid surface and enter the gas phase, because the free path of the light and heavy molecules is different, so the molecules of different substances after escaping from the liquid surface are different distances, if a condensing plate can be properly set, the light molecules reach the condensing plate is condensed and discharged, while the heavy molecules can not reach the condensing plate along the mixed liquid discharge. In this way, the purpose of material separation is achieved.
