Current extraction methods commonly used in CBD include organic solvent extraction and supercritical carbon dioxide extraction.

In addition, there are individual companies that use subcritical water extraction. Most domestic companies use organic solvent extraction.

Cannabis/hemp is a cannabis plant in the Moraceae family. It is an annual erect herb with a height of 1 to 3 meters. The branches have longitudinal grooves and densely grown gray-white appressed hairs. The leaves are palmately divided, and the lobes are lanceolate or linear-lanceolate, especially the dried flowers and trichomes of female plants.

The tetrahydrocannabinol (THC for short) in cannabis is an addictive drug component. THC has mental and physical activity after inhalation or oral administration. Humans have a history of smoking marijuana for more than a thousand years, and the use of drugs and religion in the 20th century tends to increase

Cannabis refers to marijuana with tetrahydrocannabinol (THC) <0.3%, without drug use value, but with medical and other commercial value.

The flowers and leaves of cannabis/hemp/hash contain an important active ingredient cannabidiol (CBD), which is a non-addictive ingredient in cannabis. The latest research progress shows that CBD has good biological activity and can be used to treat Alzheimer’s Murder disease (Alzheimer’s disease), anti-spasm, anti-anxiety, anti-tumor, psychosis, Parkinson’s disease and other serious diseases.

 Carbon dioxide (CO2) extraction is commonly used in the manufacture of various foods and other products, and is becoming more and more popular for extracting high-quality hemp oil rich in cannabidiol (CBD).

Currently, Cannabis/hemp can be extracted in many ways, and ethanol extraction is the most common method. Supercritical carbon dioxide extraction (SCFE) is to contact the supercritical carbon dioxide with the substance to be separated under the supercritical state, so that it can selectively extract the components with different polarity, boiling point and molecular weight in sequence. This sustainable green technology can be used to extract high-purity oils containing high aromatic compounds.

Hemp Oil CO2 Extraction Process

Drying → crushing → passing through a 30-mesh sieve → entering the extraction kettle → increasing pressure and heating → low pressure separation → Cannabis/hemp essential oil

  • The extraction kettle is filled with crushed Cannabis/hemp material
  • The CO2 high-pressure pump presses the pressurized carbon dioxide gas (SC-CO2) at the optimal temperature into the extraction kettle.
  • Supercritical carbon dioxide interacts with cannabis to dissolve the cannabinoid compounds contained in it.
  • Supercritical CO2 transports hemp oil particles to the separator through a pressure release valve.

  • In the separator, the pressure is lower and the carbon dioxide is separated from the hemp oil.
  • The carbon dioxide rises and is sent back to the carbon dioxide tank for reuse.
  • Cannabis oil, wax and resin fall in the separator and are then captured by the collection container.
  • The resulting material is further processed into various products, such as CBD-rich “hemp oil” without any solvent.

The cannabis extraction test process carried out in the HUAN BIT laboratory obtained the following results:

Effect of extraction pressure on extraction rate

When the fixed extraction temperature is 50 ℃, the extraction time is 2 h, and the CO2 flow rate is ** ML/L/Min, the effects of extraction pressures of 150, 200, 250, 300, and 350 par on the extraction rate of essential oils are investigated respectively. The process extracts Cannabis/hemp essential oil and calculates the extraction rate.

The extraction pressure changes the density of supercritical CO2, thereby affecting the extraction rate of essential oils. Increasing the extraction pressure will increase the extraction rate of essential oils. When the pressure is 300 par, the extraction rate reaches a maximum of 0.271%, but the pressure continues to rise to At 350 par, the extraction rate drops to 0.261% instead. Therefore, 300 par is the optimal extraction pressure.

Effect of extraction temperature on extraction rate

When the fixed extraction pressure is 250 par, the extraction time is 2 h, and the CO2 flow rate is ** ML/L/Min, investigate the effects of extraction temperatures of 40, 45, 50, 55, and 60 ℃ on the extraction rate of essential oils. The process extracts Cannabis/hemp essential oil and calculates the extraction rate.

Increasing the temperature can accelerate the thermal movement of molecules, which in turn increases the diffusion rate of the solute. With the increase of extraction temperature, the extraction rate of essential oils increases, and the extraction rate is 0.266% at 50 ℃, which reaches the maximum. When the extraction temperature continues to increase, the extraction rate of essential oils decreases. Therefore, 50 ℃ is the optimal extraction temperature.

Effect of extraction time on extraction rate

When the fixed extraction pressure is 250 par, the extraction temperature is 50 ℃, and the CO2 flow rate is ** ML/L/Min, investigate the effect of extraction time on the extraction rate of essential oils at 1, 1.5, 2, 3, and 3.5 h. The process extracts Cannabis/hemp essential oil and calculates the extraction rate.

When the extraction time was 1 to 3.5 h, the extraction rate of Cannabis/hemp leaf essential oil increased with the increase of the extraction time, and the maximum extraction rate was 0.272% at 2 h. When the extraction time continues to become longer, the extraction rate decreases instead. It may be that the long extraction time causes other pigments and components in the system to be extracted. Therefore, the extraction time is preferably 2h.

The influence of CO2 fluid flow rate on extraction rate

When the fixed extraction pressure is 250 par, the extraction temperature is 50 ℃, and the extraction time is 2 h, the CO2 fluid flow rate is **, **, **, **, ** ML/L/Min. Influence, extract Cannabis/hemp essential oil according to the extraction process, and calculate the extraction rate.

With the increase of CO2 fluid flow rate, the extraction rate of Cannabis/hemp leaf essential oil also increases. When the CO2 fluid flow rate is ** ML/L/Min, the extraction rate of essential oil reaches the maximum, which is 0.266%. When it continues to increase, The extraction rate decreased slightly. It is speculated that appropriately increasing the CO2 fluid flow rate is beneficial to the extraction of essential oils, but if the flow rate is too large, the contact time between the CO2 fluid and the hemp leaf powder will be reduced, which is not good for the extraction of essential oils. Therefore, the CO2 flow rate is ** ML/L/Min.

CO2 extraction process for cbd oil

The single factor experiment and response surface method were used to optimize the extraction process of hemp leaf essential oil. The results of variance analysis showed that in terms of factors affecting the extraction rate of Cannabis/hemp leaf essential oil, extraction time>CO2 fluid flow>extraction pressure>extraction temperature.

Combined with the actual operability and convenience of the extraction process, finally the process conditions were changed to extraction pressure 290 par, extraction temperature 49 ℃, extraction time 2h, CO2 flow rate ** ML/L/Min, and the actual extraction rate obtained was 0.283 %, which is close to the theoretical value of 0.281%, and the actual deviation between the predicted value and the true value is −0.71%. The two have a good fit, indicating that the optimized extraction process parameters based on the response surface method are accurate and reliable, and have practical value.

How many a CBD extraction machine cost?

Costs for CO2 and ethanol extraction processes vary depending on the type of automation and how large the scale of operation is. Each CBD extraction method requires a different amount of space to house the extraction equipment.
Both CO2 and ethanol extractions from cannabis create changes throughout different phases that use temperature and pressure. There are a number of factors that contribute to the overall costs of a CBD extraction machine.

The truth is a CBD extraction machine can range anywhere from a few thousand dollars to half a million dollars or more depending on the technology itself. A smaller extraction system for R&D purposes can be considered a “desktop co2 extractor” extractor and can use a number of solvents in order to extract CBD. This can be hydrocarbon, ethanol, or CO2.

For any size extractor, hydrocarbon and ethanol extraction equipment are generally much less expensive than supercritical CO2 extraction equipment. This is because CO2 equipment is highly specialized to handle the operating pressures necessary for CO2 to reach the supercritical state which makes it efficient for extraction.

Of course, the size of an extractor no matter the extraction method used is directly proportional to the cost of the machine. While some extractors are designed to process 10 to 80 pounds per day and can cost tens of thousands of dollars, other extractors can be designed for industrial levels of hemp processing that can cost hundreds of thousands.
