Abstract
The invention discloses a method for pretreatment of flowers and leaves of industrial hemp before supercritical extraction. The invention belongs to the field of plant extraction, and particularly relates to a pretreatment method for the flowers and leaves of industrial hemp. The invention aims to solve the problems of low extraction amount, influence on extraction efficiency, non-uniform accumulation, easy generation of dust accumulation locally and influence on extraction effect due to low bulk density of the flowers and leaves in direct supercritical extraction of crushed flowers and leavesof industrial hemp in the prior art. The pretreatment method comprises the following steps: 1, conducting mixing to obtain mixed raw materials; 2, conducting granulating to obtain wet pellets; and 3,conducting drying to obtain prefabricated pellets of the flowers and leaves of industrial hemp. The method has the advantages that 1, unit bulk density is increased by 30-50%, stacking is stable, andcarbon dioxide gas can stably and uniformly flow among substances; and 2, certain pressure resistance is achieved, and breaking is not likely to happen. Little fine dust is generated, and during extraction, dust accumulation is not likely to be generated locally. The method is mainly used for pretreatment of the flowers and leaves of industrial hemp and faciliates supercritical extraction of cannabidiol.
