How to Do Ethanol Extraction?

Ethanol extraction is not only popular at chemical and industrial fields, but also used in people’s daily life, because ethanol has a pretty good solubility. So many people have been extracting substances by using ethanol as washing solvent for a while. And next let’s go through the process of making extraction at home and the equipment we need:

How to Do Ethanol Extraction?

  1. The first step is to wash the hemp plant, in order to extract cbd from hemp plant. For this step, you can make it at a set of glassware. After this step, you could get a liquid mixture of cbd and ethanol and solid residue, then next step what you need to do is to separate the two substances.

  2. The second step is to separate the liquid and the solid. For separating liquid and solid substances, we often use the filtration method. The equipment we need is a filter. And then pour the mixture on the filter, then the solid substances will stay on the filter, while the liquid substances will flow into the other container. In this case, we can generally get the cbd liquid.

  3. The third step is to get the ethanol within liquid evaporated, in order to concentrate the cbd. After evaporating ethanol, you will get a highly concentrated form of the botanical components harvested from the hemp plant.

  Ethanol is very suitable for extracting the THC, CBD, terpenes, chlorophyll, fats, lipids and wax compounds from all kinds of plants, which is widely used in many fields. For example, it is widely used to wash plant materials in chemical experiments, chemical purification, chemical pharmacy, preparation of traditional Chinese medicines and many other fields.

How do You Extract Ethanol?

In industry, ethanol is produced by two methods, which are starch fermentation or ethylene direct hydration. Fermentation method, the raw material of fermentation method can be agricultural products containing starch, such as cereals, potatoes or wild plant fruits and so on. Waste molasses from sugar mills can also be used or cellulose-containing wood chips, plant stems and so on. After certain pretreatments, these substances are hydrolyzed (with waste honey as raw material without this step) and fermented to produce ethanol. Ethylene hydration method, ethylene direct hydration method, which is the direct reaction of ethylene and water to produce ethanol under the conditions of heating, pressurization and the presence of a catalyst. The raw material of this method-ethylene can be obtained from petroleum cracking gas. Low cost and large output, which can save a lot of food.

What is the Best Ethanol Extraction Equipment for Cannabis?

There are many equipment for extracting cannabis, such as rotary evaporator, short path distillation, industrial centrifuge and so on. However, the best cannabis extraction equipment is industrial centrifuge, which is very high-efficiency and energy-saving.

What Equipment do I Need to Shatter Materials?

At present, there are three main methods for extracting cannabinoids: solvent extraction, supercritical CO2 fluid extraction and subcritical fluid extraction. The purification methods are all column chromatography, but the chromatographic packing is different. After extracting the cannabis extract by the solvent extraction method, the industrial cannabis oil rich in CBD is further obtained by the column chromatography separation and purification method. The main processes include screening, baking, leaching, column chromatography and so on.
