A closed-loop extractor mainly consists of three parts: a solvent tank, a material column and a receiving foundation. Some upgraded versions add a dewaxing column as the fourth part, or equip the material column with a dewaxing structure directly. The closed loop hydrocarbon extraction system is used to conduct a plant extraction in a sealed vacuum system. The closed-loop system can be kept during the plant extraction without exposing any solvent to the air. The butane, propane or the combination of them are generally used as the solvent.
It’s well-known that a closed loop extractor is widely used for the extraction and concentration of substances in chemical, biochemical, industrial fields and other fields. In the whole closed loop extraction equipment, people usually use ethanol as the washing solvent to extract substances from the sample materials. And a closed loop extractor is mainly used for cannabinoid extraction. In the process, cannabis leaves will be put into solvent and fully washed by ethanol. During the washing process, the cannabinoid that is soluble will be removed out and then collected in the receiving tank. The extracted cannabinoid can be used as not only medicine, but also entertainment supplies.
