Short Path Distillation


What is Short Path Distillation?

Short path distillation is an effective separation method that is used to separate liquid and liquid, which is much more effective than traditional separation method. Short path distillation is a special separation method that can operate under extremely high vacuum.

Short path distillation can protect the specialty of substances and also save energy. Short path distillation is specially used for the extraction of natural health care products, which can get rid of chemical reaction to keep the nature of products.

Why Use Short Path Distillation?

The short path distillation is a technique that removes solvents from mixtures through evaporation, which is mainly used for liquid-liquid separation. As one of the most high-efficiency distillation techniques in people’s using, it can solve the problems that conventional distillation technology can’t.

As well, there are other possible reasons why the short path distillation is so widely used. Firstly, it requires a smaller working space compared to most conventional distillation techniques, which is much easier to use. And the desired purity level can also be reached. Secondly, it has a relatively low distillation temperature. Compared to the simple distillation, the materials can be separated even though there is a small temperature difference. Thirdly, the short path distillation is a physical process, which can well protect separated substances from being polluted and damaged. Furthermore, the less material will be lost because the liquid only need travel a short distance in the short path distillation. It efficiently reduces material waste. Therefore, the short path distillation has become more and more well-received.


Introduction to Short Path Distillation


What are Short Path Distillation Used for?

  Distilling cannabis oil

  The CBD extraction is made by distillation (by separation of the components or substances of the liquid mixture by separation of selective evaporation and condensation). Vaporable liquid with alcoholic herbaceous plants (leaves and flowers), a mixture of all the cannabinoids dissolved. Then evaporate the solution and mix with a hemp seed oil at a certain ratio.

  Homemade short path distillation

  Technically, people manufacture short path distillation in professional factory and make it with high-quality glass and other materials. Nowadays, people could make short path distillation at home by themselves. With the basic theory of short path distillation, people could use some simple materials to make a short path distillation. The most popular materials people like are metal tubes and containers. Connecting these materials together could work like a real short path distillation.

  Distillation apparatus parts

  There are several kinds of distillation equipment used nowadays. Even though these kinds of distillation equipment are used for different situations, their distillation apparatus parts are very similar, including evaporation flask, receiving flask, condensing part and other parts. These three parts play a very essential role in distillation process, each of them is indispensable.

  Fractional distillation of ethanol

  Fractional distillation of ethanol is to separate or extract substances from mixtures by using ethanol as the washing liquid, because the solubleness of ethanol is suitable to be a washing liquid. This method is widely used in chemical experiment, chemical purification, chemical pharmaceutical, Chinese traditional medicine and so on. Ethanol is always used to be the washing liquid because of its solubleness.

  CBD boiling point

  As we all know, the boiling points of substances can be influenced by temperature, pressure and any other factors. cbd is widely used and processed by people in chemical field, industrial field, and any other fields. The boiling point of cbd is 463.9℃at760mmHg, while the boiling point of cbd is 200℃ under pressure 2.66Pa.

  Short path distillation principle

  Short-path distillation equipment is a new separation technology operating under high vacuum conditions. This kit has the advantages of low distillation temperature, short heating time and high separation efficiency. It is especially suitable for the separation of high boiling point, heat sensitive and easy oxide system.The principle of short path distillation is to extract substances through getting mixtures evaporated and then condensing them. What’s more, short path distillation is also used on concentrating liquid through evaporation process.

  Application of short path distillation

  Short path distillation is mainly used in the separation and extraction of unstable heat-sensitive chemistry. It is widely used in industrial field, chemical field, cooking field,essential oil field, hemp-processing field, pharmaceutical field, regeneration of waste oil field and so on. With the development of society, all these fields will use short path distillation more and more.

  Short path distillation CBD oil

  With the rapid development of society, government now has been setting more space for hemp and its related fields. Therefore, cbd oil is becoming more and more popular, which is one of the most popular hemp-related fields in society. Short path distillation has a very high efficiency on distilling cbd from hemp, in order to make cbd oil next step.

  Using short path distillation to distill cbd from hemp, not only guarantees the purity of extracted cbd, but also saves a lot energy, including heat resource and hemp material.

  Short path distillation is an effective device for making cbd oil. When you make cbd oil by short path distillation, the first step is to check if the short path distillation is ready for operating. Then put hemp into feeding flask. Under the action of knifing, the hemp is spread evenly and cbd gets evaporated into gas phase. The materials that haven’t been evaporated will be collected in the recombination flask.

Difference

Extraction vs Distillation

  Extraction is to extract one certain substance from mixture through technology, while distillation is to distill one or more substances from mixture. They are pretty similar, but there are still some differences. Extraction is more precise, and distillation is more simple to separate substances.

Short path distillation vs Wiped film

  Short path distillation is to make distillate through molecular free path, and then set a condensing area to separate evaporated substances out of the air. Compared with short path distillation, wiped film evaporator divides the sample material into a thin film evenly, in order to accelerate the evaporation speed and improve the heating efficiency. These two distillation methods are both to make distillate but have different working theory.

What does distillation separate?

  Distillation is to separate liquid and liquid, liquid and solid depending on their different boiling points. The substances with lower boiling points will be evaporated and so separated with the other substances in the mixture. Then condensing the evaporated substances from gas-phase into liquid-phase for users to get. So the substances that distillation separates can be liquid and liquid, also liquid and solid.

Difference between evaporation and distillation

  Evaporation and distillation are very similar, which are to separate different substances within one mixture liquid. But there is still one essential difference between evaporation and distillation. Evaporation is to separate solid substances out of the mixture. For example, separate salt from sodium chloride solution. And distillation is to separate different liquid substances with different boiling points. For example water and ethanol.

Difference between short path distillation and molecular distillation

  As we all know, short path distillation and molecular distillation are quite similar in many ways, but there are still some differences between them. Molecular distillation is more complicated than short path distillation. Short path distillation can process more kinds of materials than molecular distillation can. What’s more, molecular distillation has to work under specific pressure.
