Molecular Distillation Equipment


Molecular distillation is also called short path molecular distillation, which is a distillation method under high vacuum. The average free path of the vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so that the difference in evaporation rate of each component in the liquid can be used. Molecular distillation is to separate the mixtures of liquids.

molecular distillation technology

  Molecular distillation is depending on the difference of molecular motion mean free path of different substances. Molecular distillation is more complicated than simple and traditional distillation, because it has more advanced technology. And molecular distillation has a high working efficiency because of it’s high technology.

molecular distillation pressure range

  Molecular distillation is a liquid-liquid separation method that works under high vacuum. Generally, the pressure range of molecular distillation is under 0.01 torr, which is under 1.3 Pa. This very high vacuum environment makes sample materials can boil at the temperatures that are much lower than sample materials’ boiling points, which saves a lot of energy.

molecular distillation essential oils

  Essential oils are made through the extraction and concentration of substances by molecular distillation. Essential oils have high concentration, so making essential oils takes a lot energy for molecular distillation. Therefore, essential oils have a very high nutrition and can be very beneficial for people, which is the reason that essential oils are quite hot and popular in the market.

molecular distillation cannabis

  Molecular distillation has a very high efficiency on the concentration and extraction of substances. Therefore, people always use molecular distillation to extract cannabis, because molecular distillation can process a big bulk of cannabis at the same time. There are so many popular cannabis production made by molecular distillation in the market.

uses of molecular distillation

  Molecular distillation is a special and complicated liquid-liquid separation method working under high pressure, which can separate substances at the temperatures that are much lower than the boiling points of the substances. So molecular distillation is widely in many fields, for example, daily chemical, recycling and other industrial fields, petrochemicals, pharmaceuticals, plastics, food and so on.

principle of molecular distillation

  The working principle of molecular distillation is to separate substances by the differences in mean free path of molecular motion of different substances. Because the weight of different substances are different, the different substances will run into different ways during the working process. Therefore, that’s why the different substances are separated by molecular distillation.

disadvantage of molecular distillation

  Molecular distillation is widely used by many people because of it’s high efficiency. However, it also has some disadvantages. For example, it is more complicated than the traditional and simple separation methods, which means it is harder to operate; the equipment and technique requirements of molecular distillation are very high, which means it costs a lot more than the traditional and simple separation methods.

advantages of molecular distillation

  As we all know, molecular distillation is an effective liquid-liquid separation method. Therefore, it has several advantages: it has low evaporation temperature, which means it can save more energy; it has less pollution and does not produce toxic substances, which is very helpful to our environment; it takes less time to produce more end products. Besides these advantages, molecular distillation also has other advantages.

application of molecular distillation

  There are so many applications of molecular distillation in many fields. For example, molecular distillation can distill food and protect the nature at the same time in food-making field; molecular distillation can extract essential oil, lanolin and other substances in make-up field; molecular distillation can distill Vitamin A and Vitamin E from mixture in pharmaceutical field. Besides above, there are still more applications of molecular distillation.

Molecular distillation theory

  Molecular distillation is a distillation technology being operated under high vacuum. It is a special liquid-liquid separation method and is different from traditional distillation method, which works depending on the boiling points difference. Molecular distillation works depending on molecular weight difference among different substance molecules.

Molecular distillation process

  The material is added from the top of the evaporator, and is continuously and evenly distributed on the heating surface through the liquid distributor on the rotor. Then the wiper scrapes the liquid into a very thin, turbulent liquid film and spirals. During this process, the light molecules that escape from the heating surface are condense into a liquid on the built-in condenser after a short route and flow down the condenser tube through the discharge tube at the bottom of the evaporator. The heavy molecules are collected in a circular passage under the heating zone, and then flows out through the discharge pipe on the side.

Molecular distillation cbd

  Molecular distillation is widely used to separate heat sensitive, viscous and/or high boiling point materials from mixtures and can guarantee the materials quality. So molecular distillation is widely used on distilling cbd from hemp. And the cbd extracted from hemp can be used in many different fields, for example, pharmaceutical field, industrial field, chemical field, biochemical field, cooking field, textile field and other popular field.

what is molecular distillation

  Molecular distillation is a complicated liquid-liquid separation method, which is more effective than simple and traditional liquid-liquid separation methods. Molecular distillation is to separate substances by the differences in mean free path of molecular motion of different substances. Molecular distillation is widely used in many fields, for example, chemical labs, industrial factories and other fields.

what does molecular distillation do

  Molecular distillation is widely used in the concentration, purification, distillation and separation of substances, which can separate different molecules effectively on a chemical level. Molecular distillation can be used to distill substances from mixture, purify substances into purer substances and separate two kinds of substances from the one mixture. Therefore, molecular distillation is quite popular in the market.

how does molecular distillation work

  Molecular distillation works through the differences in mean free path of molecular motion of different substances. During the working process, there are mainly four parts: molecules diffuse from the liquid body to the evaporation surface; free evaporation of molecules on the surface of the liquid layer; molecules fly from the evaporation surface to the condensation surface; molecules get condensed on the condensation surface.
