摘要： Raw plant material is mixed with ethanol under pressure to extract essential elements. The resulting crude oil and ethanol with the dissolved essential elements is separated from the raw plant material and filtered to remove particulates, waxes, lipids, fats and dissolved impurities. The ethanol is then evaporated from the resulting mixture of crude oil and ethanol, and the remaining crude oil then undergoes decarboxylation and distillation to obtain the essential elements. The ethanol may be chilled before adding it to the raw plant material.

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.

摘要： Concentrated cannabis extract is obtained from raw cannabis plant material using a mixed solvent extraction process. The cannabis is soaked and agitated in a chilled mixture of butane, propane and isobutane. After removing the solid plant material, the remaining solvent mixture, now with dissolved extracts, is heated to remove the solvents. The remaining, viscous oil is then heated in a vacuum oven to purge the traces of solvent and result in a brittle shatter.
