Abstract

The invention relates to the technical field of chemical engineering and in particular to a method for preparing cannabidiol. The method comprises a pretreatment device, a drying device, an extractiondevice, a concentration device and an aftertreatment device, wherein the pretreatment device is connected with the extraction device through the drying device; the extraction device is connected withthe aftertreatment device through the concentration device; the pretreatment device comprises a feeding hole, a cooling device and a crushing device; the feeding hole is formed in the upper end of the cooling device; and the crushing device is arranged at the lower end of the cooling device. Raw materials are fed into the cooling device from the feeding hole, the cooling device is capable of cooling till freezing on the raw materials, then cell sap in cells of the raw materials can be frozen, the raw materials are further fed into the crushing device for a rough crushing process, a medium crushing process and a fine crushing process, the problems that cannabidiol is poor in permeability into an organic solvent because of cell walls and the cannabidiol is damaged because of concentration heating can be solved, the raw materials can be sufficiently utilized, and the yield can be effectively increased.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method of cannabidiol. Background technique [0002] Cannabidiol, English Cannabididiol, referred to as CBD, a kind of cannabinoid, is the main chemical component in industrial hemp, mainly extracted from female cannabis plants. Cannabidiol is characterized by no addiction, anti-spasmodic, anti-anxiety, Anti-inflammatory and other pharmacological effects, which is also the value of cannabidiol, the extraction method mainly adopts the extraction method of soaking in organic solvents, and the following problems exist in the extraction method of soaking in organic solvents in oil production: [0003] (1) Since the extract components are contained in its tissue cells, the periphery of the cells is a cell wall composed of a layer of cellulose, hemicellulose and pectin, and the cell wall is protoplasm. The existence of the cell wall will affect the p...
