At present, there are more than 70 kinds of cannabinoids isolated from cannabis plants by extracting tank extractor, of which CBD (cannabinol) and THC (tetrahydrocannabinol) are the highest. The significant difference between CBD and THC is that THC has hallucinogenic addiction. CBD does not make people addicted to fantasy, which has outstanding effects in analgesia, sleep aid, anti-inflammatory, antioxidant, neuroprotection, anti-anxiety, anti-tumor, liver protection and anti-diabetes. With the extensive research on the efficacy of CBD, its application is increasingly rich. In general, you can get CBD from the following hemp plants by closed loop extractor:
lIndustrial hemp: its THC content is less than 0.3%;
lMarijuana: drug marijuana, whose THC content is more than 0.5%;
lMedical marijuana: THC content in 0.3% ~ 0.5%.
A prerequisite for CBD extraction from hemp plants by closed loop BHO extractor is to reduce THC content as much as possible. Therefore, it is feasible to choose industrial hemp with the lowest THC content and the most CBD content. How to extract CBD from industrial hemp? At present, there are three common methods: solvent extraction, supercritical CO2 extraction and olive oil extraction.
Solvent closed loop system is a mature method to obtain CBD from industrial hemp by solvent extraction. Its basic principle is to soak or spray pretreated plant materials with ethanol and then extract phenolic substances from plants. The advantages of solvent closed loop extractor system are economy and simplicity. However, the final extracted CBD oil is a mixture, so some impurities may remain, which may affect the appearance and taste of the product. For example, the residual chlorophyll will make the oil green and taste bitter. In addition, the extraction process is dangerous and ethanol is easy to burn.
CO2 will change its state with the change of air pressure and temperature. Supercritical CO2 is a kind of substance between gas and liquid. On the one hand, it has the liquidity of liquid, so it has the ability to extract some fat-soluble substances. On the other hand, it has good diffusivity similar to gas. Supercritical CO2 active closed loop extractor is a new material extraction technology based on the characteristics of supercritical fluid. This extraction method usually requires the use of a special closed loop extractor parts with three chambers. Although the material extracted by this method is pure and has no chlorophyll, its use is still limited by expensive close loop BHO and complicated operation.
Olive oil closed loop extract system is a simple and convenient method for homemade CBD products at home. Heat the industrial hemp plant to a specific temperature and hold it for a period of time to activate the chemicals in it. After adding to olive oil, the plant material was heated to 100 ℃ for 1-2 hours to obtain cannabinoid and CBD oil. Because olive oil is perishable, it must be stored in a cool and dark place. Moreover, the production capacity of olive oil passive closed loop extractor is too low and not suitable for mass production.
Wholesale closed loop extractor have become more and more popular for extracting cannabinoids. Various kinds of active BHO closed loop extractor in SUNTHAI OEM can be customized according to clients' requirements. There are different designs of closed loop extractors with recovery pump but the basic features and functions are the same. Therefore, please feel free to send us your draft drawing or concept, our technical will refine your design.
