Molecular distillation is a special liquid-liquid separation technology. It is different from traditional distillation. It depends on the boiling point difference separation principle, but is related to the molecular weight of the distilled mixture. It can realize the operation far away from the boiling point. The greater the molecular weight difference, the greater the molecular free path difference, and the purer the distillate. The molecular free path here λ Is the distance traveled between two adjacent collisions of a molecule.

Under the condition of high vacuum, the liquid mixture flows along the heating plate and is heated. According to the different molecular average free path of substances with different molecular weight, the size and degree of evaporation of their molecular average free path between the vaporization surface and the condensation surface are also significantly different. The molecular average free path of light component molecules is large, while the molecular average free path of recombinant component molecules is small, So that the light component can just reach the condensing plate and be condensed, leaving it along the condensing plate; The recombinant molecules are left along the heating plate because they can not reach the condensing plate, so as to separate different substances.

As a high-tech separation technology synchronized with the world, molecular distillation technology has incomparable advantages over other separation technologies:

1. Operate at a temperature far below the boiling point of the material, and the residence time of the material is short; It is conducive to the separation of high boiling point, heat sensitive and easily oxidized materials;

2. Effectively remove substances in liquid, such as organic solvent and odor, which is a very effective method for the desolvation of liquid after solvent extraction;

3. The product can be evaporated selectively to remove other impurities. More than 2 substances can be separated at the same time through multistage separation;

4. It can effectively remove light molecular substances (deodorization), heavy molecular substances (decolorization) and impurities in the mixture;

5. The separation process is a physical separation process, which can well protect the separated substances from pollution, especially maintain the original quality of the natural extract;

6. There is no boiling and bubbling phenomenon. Molecular distillation is free evaporation on the surface of the liquid layer. It is carried out under low pressure and there is no dissolved air in the liquid. Therefore, the whole liquid cannot boil and there is no bubbling phenomenon in the distillation process;

7. High separation, higher than traditional distillation and ordinary thin film evaporator;

8. Easy to form continuous production and simple operation;

9. Molecular distillation has a short evaporation range, the average free path of the molecule is generally no more than 25mm, and the energy consumption is small.

10. The feed tank can optionally realize the pre heating function, and the preheating temperature can be adjusted;

11. Each interface is sealed with fluororubber gasket with good air tightness. If the customer needs corrosion resistance, it can be replaced with Teflon material.
