About CO2 extraction machines for CBD Oil

With the successful 300L C-50S CO2 extractor of HUAN BIT selling well all over the world, we realized that we could do better, so we set out to design the system to meet the needs of commercial-scale manufacturers and launched the C-150D supercritical CO2fluid extraction equipment. The commercial-grade supercritical CO2 extraction system is automated and can be operated without any special skills.

Supercritical CO2 Extraction for High Quality CBD Oil

C-150D has dual 150-liter extractors for processing plant matter. The flow rate is 15.7 KG/Min, and it has a hydraulically driven extractor cover, which can easily load and unload the prepared plant material for you. It can process 720-1000 pounds of dry plant material per day. The C-150D supercritical CO2 extraction system is optimized for Cannabis/hemp extraction. If you customize the HUAN BIT supercritical fractionation column, you can use the SFF technology provided by us to separate more wax during the extraction process without too much More post-processing.

C-150D can also carry out subcritical treatment (low pressure/low temperature), so using this system, you will get the best of both worlds!

The C-150D supercritical CO2 extraction machine is used to extract different molecules from plants using CO2 fluid. The use of CO2 means that there is no longer a need to worry about typical solvents that may harm the use but also affect the chemical composition of the extracted oil, thus creating a high-performance extraction system for many applications.

In our commercial-grade supercritical extraction equipment, the plant material is decomposed at the molecular level through the container of plant material that allows supercritical CO2 to pass through. When CO2 passes through plant materials, it will deprive you of the plant components of the required extract and provide you with ready-made pure vegetable oils (terpenes, full spectrum, etc.).

HUAN BIT provides a complete engineering and design process. This includes on-site engineering reviews, detailed design and drawing packages, and project management plans. After installation, we will provide you with complete training and method development.

About Cannabis oil

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.

How to extraction hash oil

 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.

It has the characteristics of simple operation process, short extraction time, low extraction temperature, high extraction efficiency, and no solvent residue pollution. At present, this technology is used in many research fields, especially in the extraction of plant essential oils, such as the extraction of agarwood, capsaicin, turmeric, CBD, and other essential oils or pigments, as well as the extraction of many other plant essential oils. Applied to this technology, the above fully demonstrates that SCFE technology has advantages in essential oil extraction.

Method for Supercritical CO2 extraction of CBD oil


Cannabis/hemp flowers and leaves are picked at the mature stage, dried, crushed and sieved.

Extraction method

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.

Research of method for Supercritical CO2 extraction of CBD oil

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.


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.
