short path molecular distillation

Category:

  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.

  Advantages:

  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.

Extraction cycle

  The procedures about molecular distillation extracts cannabidiol from medical hemp are as follows:

  Step one:select medical hemp extractum to be used;

  Step two:put extractum into feeding tank to be heated. Put liquid-phase extractum into molecular distillation by

  feeding pump after solid extractum is turned into liquid-phase. Distilling extractum liquid with molecular

  distillation. Vacuuming the molecular distillation with a vacuum pump, and control the stirring speed. Put the

  cooling or heating medium into the condenser in the molecular distillation at the same time.

  Step three:collect cannabidiol in the collection tank 2,collect extractum residue in the collection tank 2, and pass

  the heat medium into the jacket of collection tank 1 and collection tank 2 at the same time which should also be

  heated to keep the temperature.

  Step four:heat the cold medium in cold trap. A small amount of tetrahydrocannabinol and solvent are obtained in

  the collection tank 3.

  Step five:put extractum into feeding tank when the extractum almost runs out, and end the working process until

  the extractum runs out.
