Cannabis plant raw material is mixed with ethanol and spin-dried to extract cannabinoids. The ethanol can be cooled before adding it to the cannabis plant raw material, and a non-polar solvent stage can be used to increase the extraction yield. The resulting crude oil and ethanol with the dissolved cannabinoids are separated from the plant raw material. cannabis and is filtered to remove particles; Waxes, lipids, fats and dissolved impurities. Then; Ethanol is evaporated from the resulting oil and ethanol mixture, and the remaining oil is subjected to brine washing, decarboxylation, and distillation to obtain the cannabinoids and other desirable volatile phytochemicals. |
