short path molecular distillation


  Working Process:

  Feed material is delivered from a feed flask into the main jacketed evaporator, having

  heating frompei the jacket,and adiagonally slotted wiper mechanism forcing liquidaround

  and downward in a thin film on the inside. In the center of the body is a closely positioned

  internal condenser, providing a short path for vapor molecules traveling from the heated

  surface to the condenser surface. During the journey downward, lighter (lowerboiling

  point) fractions of the liquid begin to vaporize, move to the internal condenser and

  condense, falling down as a liquid into a well that captures and separates the distilled

  liquid which flows into the Distillate receiving flask. Heavier residue material (like

  chlorophyll, salts, sugars, heavy wax) does not evaporate and instead travels the length of

  the main evaporator body and flows into the Residue receiving flask.


  1. Thermal separation of heat sensitive chemical compounds.

  2. The purification of organic synthetic material.

  3. The separation of effective components from the biological extracting solution.

  4.Lower the oxidation speed of heating oil, lengthen the work life of heating oil, so that can reduce the change frequency of heating oil.

  5.Used in wide temperature range, the maximum point can reach 300°C

  6,More safe, because of fully enclosing, it can avoid the high temperature oil hurt operators.

  What is Short Path (Molecular) Distillation?

  Short Path (Molecular) Distillation is a special liquid-liquid separation technology, which is different from the traditional distillation by boiling point difference separation principle, but by different substances molecular movement of the average free path difference to achieve separation.

  Process of the Short Path (Molecular) Distillation

  The process of Short Path (Molecular) Distillation when carried out in an apparatus designed for high vacuum in order to allow the molecules escape from the warm liquid into a cooler surface inside a condenser before coming in contact other molecules and finally settle down into the liquid is known as molecular distillation. This method is applied to purify heat sensitive, high boiling point, and high molecular weight materials.
