How to Extract CBD from Hemp – A Step by Step Guide

CBD isolate is one of the most popular and valuable products in the hemp industry. It is a pure form of CBD that contains up to 99 percent CBD and can be used for various applications such as edibles, vape pens, and tinctures. But how do you extract CBD isolate from hemp biomass? In this article, we will show you how to do it using the state-of-the-art equipment that we sell at Plygen Industries.

What is Hemp Biomass?

Hemp biomass is the raw material that is used to extract CBD and other cannabinoids. It consists of the dried and ground parts of the hemp plant, such as the flowers, leaves, stems, and seeds. Hemp biomass can vary in quality and potency depending on the strain, growing conditions, harvesting methods, and storage methods.

What is CBD Isolate?

CBD isolate is a crystalline powder that contains pure CBD. It is made by refining and purifying hemp extract until all other compounds are removed. CBD isolate has no taste, smell, or color and can be easily measured and dosed. CBD isolate can be used to make various products such as oils, capsules, gummies, creams, and more.

If you are looking for high-quality CBD isolate for your products or customers, we can help you produce it using our advanced equipment and labs. We also offer third-party lab testing and certificates of analysis for our CBD isolate.

How to Extract CBD from Hemp

The process of extracting CBD isolate from hemp biomass involves several steps:

Step 1: Crude Oil Extraction from Hemp Biomass

The first step is to extract the crude oil from the hemp biomass. This can be done using different solvents, such as butane, ethanol, or supercritical CO2, that dissolve the plant resins. The crude oil is a thick and dark substance that contains all the phytochemicals in the hemp plant, including cannabinoids, terpenes, flavonoids, chlorophyll, and waxes.

To extract the crude oil, you will need a reliable and efficient extraction system that can handle large volumes of hemp biomass. One of the best options for this is the Closed Loop Hydrocarbon Extraction System that we sell at Plygen Industries. This system uses butane or propane as solvents and has a closed-loop design that prevents any solvent loss or contamination. It also has a high recovery rate and a low operating cost. Another popular method is to pre-chill ethanol using Pre-chilled ethanol tank and then extract the CBD using Centrifuge extractor.

Step 2: Winterization and Filtration of Crude Oil

The next step is to remove the fats and chlorophyll from the crude oil. These compounds can affect the taste, color, and texture of the CBD products and are not desirable for consumers. To remove them, the crude oil is exposed to cold temperatures that cause the fats and other substances to solidify and separate from the oil. This process is called winterization and can be done using a Ultra-low temperature chiller.

Filtration equipment can then be used to filter out the solidified fats and chlorophyll.

Step 3: Solvent Recovery from Crude Oil

After winterization, the solvent needs to be completely removed from the crude oil. Solvents are safe to use in a lab setting and during production, but they should not be present in the final product. To remove them, a rotary evaporator or Falling film evaporator is used. A rotary evaporator reduces the volume of the solvent by spinning and heating it under a vacuum, while a Falling film evaporator create a film along the tube walls thus greatly increasing the surface area and speed up the evaporation process.

Step 4: Decarboxylation of Crude Oil

The crude oil contains mostly CBDa, which is an inactive form of CBD. To activate CBDa into CBD, heat is applied to the crude oil. This process is called decarboxylation and it converts CBDa into CBD by removing a carboxyl group.

To decarboxylate your crude oil efficiently and safely, you will need a Decarboxylation Reactor.

Step 5: Distillation of Decarboxylated Oil

To get CBD isolate from decarboxylated oil, it needs to go through a distillation process. This process separates CBD from other cannabinoids and terpenes in the oil. The distillation process involves steps including evaporating and condensing.

One of the most advanced distillation systems for CBD production is the Thin Film Distillation system, also known as wiped film evaporator. This system uses a thin film of oil that is spread over a heated surface and a high vacuum to achieve high purity and efficiency. It can separate CBD from other cannabinoids and terpenes with up to 99 percent accuracy and has a low residence time that prevents thermal degradation.

Step 6: Crystallization and Purification of Distilled Oil

The final step is to crystallize and purify the distilled oil. This step removes any remaining impurities and produces pure CBD crystals. The crystallization process involves dissolving the distilled oil in a solvent such as pentane or hexane and then cooling it down slowly. This causes CBD crystals to form and precipitate out of the solution. The crystals are then washed with cold solvent and dried.

To crystallize your distilled oil, you will need a Crystallization Reactor. This reactor can control the temperature, pressure, and stirring of your solution and has a jacketed design that allows for heating and cooling. It also has a filtration system that can separate the crystals from the solvent. The crystals can then be dried in a vacuum oven.

Conclusion

As you can see, extracting CBD isolate from hemp biomass is a complex and delicate process that requires advanced equipment.
