Extraction Process of CBD Explained – From Hemp to CBD

THE EXTRACTION PROCESS OF CBD

The extraction process of separating cannabidiol from other plant material effectively is both complex and expensive, requiring professional equipment and experts overseeing the procedure.

Cannabidiol or as most people know it CBD are found in both marijuana and hemp – two different forms of the cannabis plant. Marijuana is less favoured for making CBD oil because it contains high amounts of THC, the psychoactive compound in cannabis.

Industrial hemp plants are preferable because they are widely legal and bred to emphasize high CBD content.

The CBD in these plants can create concentrated oils via extraction. We will explain over the next 3 paragraphs different oil extraction methods.

FROM HEMP TO CBD

cbd extraction process explained

1. CULTIVATING

Organically grown hemp that has been dried and cured to avoid pesticides, chemical fertilisers or heavy metals

2. EXTRACTING

CO2 extraction allows for clean high quality CBD concentrate to be created that is safe to produce and consume

3. QUALITY

Always ask for certificates of quality when purchasing CBD extracts

4. CBD

CBD products give you safe and easy access to the full potential of cannabinoids, anytime, anywhere.

THE CARBON DIOXIDE EXTRACTION PROCESS (CO2)

The carbon dioxide extraction process employs a closed-loop extractor, a machine with 3 chambers.

One pressurised chamber holds solid carbon dioxide, or dry ice. Another chamber contains the dry plant material, and the final chamber receives the extracted product.

The solid carbon dioxide moves into the second chamber with the plant material.

Temperature and pressure change inside the second chamber to turn the carbon dioxide into a liquid.

The liquid CO2 runs through the dry plant material and separates cannabinoids from unwanted plant material. The mixture then moves into the third chamber where it exists at a higher temperature and lower pressure.

This change lets the carbon dioxide turn back into a gas and rise to the top of the chamber.

The CBD oil extracted from dry plant material stays at the bottom of the chamber.

THE OIL EXTRACTION PROCESS

The oil extraction process is the method of choice for many home extraction projects.

It’s a simple extraction method whose use dates back thousands of years. Oils like olive oil soak hemp plants for up to a couple weeks at a time.

After soaking, heating the mixture helps remove any remaining compounds from the plant from getting into the oil.

Since infused oil is delicate, it must be kept in a cool, dark place.

The imprecision associated with this extraction process makes it hard to establish exact concentrations of active compounds in the finished product of CBD oil.

THE SOLVENT EXTRACTION PROCESS

During the solvent extraction process, the plant material resides in one chamber with a liquid solvent.

Ethanol, isopropyl alcohol, butane, and hexane are examples of the solvents this extraction process can employ. These solvents mix with plant matter to suspend the active cannabinoids in solution.

The liquid then evaporates away from the mixture, leaving only concentrated oil.

This extraction process requires minimal equipment. It’s a cheap and simple way of extracting CBD oil, but there are some downsides to keep in mind as well.

One of main issues is that the solvent chosen can remind behind in the oil.

Solvent extraction is affordable, but is less desirable because of the solvents it leaves behind. The right solvent and meticulous processing can reduce this residual content slightly, but the extraction process is not flawless.
