Description basic configuration Technical Parameters Characteristics
Principle of molecular distillation :

Molecular distillation is a special liquid-liquid separation technique. It 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. Here, the molecular motion free path (indicated by λ) refers to the distance traveled between two collisions of one molecule.
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. Since the free paths of the light and heavy molecules are different, the molecules of different substances move away from the liquid surface and have different moving distances. If a condensing plate can be properly set, the light molecules reach the condensing plate and are condensed and discharged, and the heavy molecules do not reach the condensing plate and are discharged along the mixed liquid. In this way, the purpose of material separation is achieved.

Characteristics of molecular distillation technology:

As a high-tech separation technology that is synchronized with the international, molecular distillation technology has the advantages that other separation technologies can't match:
1. Low operating temperature (far below boiling point), high vacuum (no load ≤ 1Pa), short heating time (in seconds), high separation efficiency, etc., especially suitable for separation of high boiling point, heat sensitive and oxidizable substances;
2, 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 contaminated, in particular, can maintain the original quality of the natural extract;
4, high degree of separation, higher than traditional distillation and ordinary thin film evaporator.
