Abstract
A method of extracting CBD, THC, desirable oils, and other compounds from the cannabis plant includes drying the plant, grinding or chopping the plant, mixing the resulting pieces of the plant with a fluid to form a mixture, circulating the mixture through a controlled cavitation reactor to liberate CBD, THC, desirable oils, and other compounds from the pieces, and separating the liberated CBD, THC, desirable oils, and other compounds from the fluid. The method may be used as an adjunct to or in combination with traditional extraction techniques such as leaching to increase yields.
Claims11
A method of extracting oils from the cannabis plant comprising the steps of:
- (a) drying the cannabis plant;
- (b) chopping or grinding the dried cannabis plant into pieces;
- (c) combining the pieces of cannabis plant with a fluid to form a mixture;
- (d) passing the mixture through a cavitation zone;
- (e) causing cavitation events in the fluid that produce shock waves and pressure variations in the cavitation zone, the cavitation zone being defined between the outer peripheral surface of a rotor and an interior surface of a housing within which the rotor is rotatably mounted, the rotor having cavitation inducing structures on its outer peripheral surface, and wherein the step of causing cavitation events comprises rotating the rotor within the housing as the mixture passes through the cavitation zone;
- (f) as a result of step (e), liberating oils from the pieces of the cannabis plant, the liberated oils becoming entrained within the fluid;
- and
- (g) separating the oils from the fluid;
- where in step (e), the shock waves and pressure variations are controlled by varying the rotation rate of the rotor to reverse hornification caused by step (a).
