摘要：
Raw cannabis plant material is mixed with ethanol and spun-dry to extract cannabinoids. The ethanol may be chilled before adding it to the raw cannabis plant material, and a non-polar solvent stage may be used to increase the yield of the extraction. The resulting crude oil and ethanol with the dissolved cannabinoids is separated from the raw cannabis plant material and filtered to remove particulates, waxes, lipids, fats and dissolved impurities. The ethanol is then evaporated from the resulting mixture of oil and ethanol, and the remaining oil then undergoes brine- washing, decarboxylation and distillation to obtain the cannabinoids and other desirable volatile phytochemicals.
