Co2 Supercritical extraction --> Dewaxing and impurity removal (wax refers to macromolecular organic impurities) --> Evaporation to remove solvent --> Decarboxylation --> Short path wiped film distillation equipment for separation --> Crystallization filtration --> Chromatographic separation (optional) --> Drying (vacuum drying oven).

The dried hemp flower leaves are crushed and dried --> Cryogenic ethanol extraction process (The CBD extraction rate is about 90%) --> Multi-stage filter to remove cellulose and FAT --> Rising film evaporator for desolventize, also be called alcohol recovery --> Decarboxylation to remove residual ethanol, convert CBDA to CBD --> Wiped film molecular distillation equipment for separation & purification to get pure cbd oil --> Crystallization, Repeated crystallization filtration or adding chromatographic treatment after crystallization filtration can increase the purity to 99% --> Get CBD dry powder through vacuum drying oven.
