Molecular Distillation:
Molecular distillation is a special liquid-liquid separation technology, which is different from the traditional distillation which relies on the principle of boiling point difference, but relies on the difference in 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 from the liquid surface and enter the gas phase. Due to the different free paths of the light and heavy molecules, the molecules of different substances move at different distances after escaping from the liquid surface. If a condensing plate can be properly installed, light molecules will be condensed and discharged when they reach the condensing plate, while heavy molecules cannot reach the condensing plate and be discharged along the mixed liquid. In this way, the purpose of material separation is achieved.
Molecular distillation technology, as a high-tech separation technology that is synchronized with the world, has the advantages that other separation technologies cannot match:
1. Low operating temperature (much lower than the boiling point), high vacuum degree, short heating time, high separation efficiency, especially suitable for the separation of high boiling point, heat sensitivity, and easily oxidizable substances;
2. It can effectively remove low molecular substances (deodorization), heavy molecular substances (decolorization) and remove impurities in the mixture;
3. The separation process is a physical separation process, which can well protect the separated substances from being polluted, especially the original quality of natural extracts;
4. The degree of separation is high, which is higher than that of traditional distillation and ordinary thin-film evaporators.
