    What are Some of the Methods of Extracting CBD Oil?

    Since the extraction and sale of CBD became legal in America in 2018, more countries are set to relax their laws around cannabis. As with everything else, America leads the way.

    The CBD industry is one of the hottest in the global economy. It has made such an impact because of the many sectors that it touches: service, health, disruptive technology, e-com, food, education, and so on.

    As the industry expands, and more people become aware of the benefits of CBD, their curiosity is awakened, and they start digging up as much information as they can.

    This post will answer all your questions concerning how CBD oil is extracted.

    Different companies will employ different methods to extract CBD oil. But the top 1% of companies share one extraction method because it is incredibly convenient. Others stay out because of the exorbitant initial cost.

    The best method of extracting CBD oil is the one that bends toward safety and quality. These are some of the things that need to be considered while extracting CBD.

    • The extraction vessels must be designed to withstand the chemical properties of the solvents.
    • The extraction vessels must be used for one purpose only; multiple-use lowers CBD quality.
    • CBD oil must be extracted in an appropriate facility and environment.
    • All the ingredients used in the extraction process must be approved for industrial use by the FDA.
    • The extraction process must be supervised by trained personnel.

    Carbon Dioxide Extraction Method

    Why do most top companies use this method to extract CBD oil? It’s because it results in high yields while keeping the CBD oil as pure as can be. Most other extraction methods that require less money to set up a plant usually produce impure CBD oil not to mention the yield is many levels down.

    In this extraction method, carbon dioxide is blown at high pressure, and low temperature, against industrial hemp, effectively stripping CBD oil, terpenes, and other essential oils.

    Several pressurized chambers and pumps are used as carbon dioxide passes in a state of half gas and half liquid; beating the raw material, and then going back to storage.

    • The raw material (industrial hemp) is crammed into a high-pressure chamber
    • The supercritical carbon dioxide is guided into the chamber containing industrial hemp
    • The supercritical carbon dioxide strips CBD oil from the industrial hemp
    • The carbon dioxide and CBD oil flow into a separate chamber
    • Carbon dioxide flows back into storage, leaving pure CBD oil

    Manufacturers love this extraction method because they can automate the whole process, adjust the concentration levels, and also reuse the carbon dioxide.

    Why Manufacturers Like Using Carbon Dioxide Extraction Method?

    • You can make adjustments depending on molecular weights
    • The solvent (C02) doesn’t stick to CBD oil
    • Facilities are temperature controlled

    CBD Oil Distillation Extraction Method

    As the name suggests, steam is used to separate CBD oil from industrial hemp. The industrial hemp is crammed into a vessel with an inlet and an outlet. The inlet is attached to a steam dispenser while the outlet is attached to a tube for collecting the condensed CBD oil.

    • The steam heats the industrial hemp, resulting in vapor laden with CBD oil
    • The vapor is pushed into the collecting tube and it condenses into CBD oil and water
    • The water is distilled to separate it from CBD oil

    This method makes for significantly less yield when compared to the supercritical C02 extraction method, and thus you have to use more industrial hemp. Also, it’s difficult to adjust the concentration levels of the CBD oil. Additionally, this method has an element of risk to it, because if you heat the industrial hemp too much, you can damage the chemical properties of CBD oil.

    Hydrocarbons Extraction Method

    This extraction method shares a similarity with the distillation process, except that water is replaced by a hydrocarbon solvent in stripping the CBD oil and terpenes.

    Once the solvent is introduced into the raw material (industrial hemp) it binds the CBD oil, and the solution is collected in a separate chamber, but at room temperature the solvent evaporates, leaving behind CBD oil.

    The hydrocarbons extraction method is significantly low-cost, has a high rate of extraction, and even the levels of potency are high.

    But one of the big concerns with this extraction method is that should the solvent residue exceed the limit, then you have the question of toxicity.

    Carrier Oil Extraction Method

    As the name suggests, it involves the use of carrier oils. First off, the industrial hemp is heated for a certain length of time, bringing its chemical properties to life.

    Then the carrier oil is added into the industrial hemp, and the heating continues, causing the CBD oil and terpenes to come out of the industrial hemp, and they are dissolved into the carrier oil.

    The solution flows into another chamber, where the carrier oil is separated, but the CBD oil gotten through this method doesn’t have high potency.

    What the Best Method of Extracting CBD Oil?

    From the standpoint of a manufacturer, the C02 supercritical extraction method is hands down the best. Not only is it safe but the yield is high. Also, the carbon dioxide can be used many times over.

    It’s well worth it investing in a plant for supercritical C02 extraction method because it will help you produce quality CBD products.

    In the CBD industry, your reputation precedes you, and if you want to get sales, people must say good things about your product.
