Abstract

See full text

Disclosed herein is a method for producing crystalline cannabinoid particles in continuous mode. The method comprises preparing a cannabinoid-rich solution that comprises a first cannabinoid, and inducing the cannabinoid-rich solution to a supersaturated state in which the first cannabinoid has a supersaturated concentration that is greater than a corresponding saturation concentration of the first cannabinoid. The method further comprises flowing the cannabinoid-rich solution through a tubular reactor in a continuous manner under turbulent flow conditions to form a plurality of crystalline cannabinoid particles and a cannabinoid-depleted solution within the tubular reactor, and separating crystalline cannabinoid particles from the plurality of crystalline cannabinoid particles and the cannabinoid-depleted solution. The turbulent flow conditions are defined by a Reynold number that is greater than a critical Reynolds number for the cannabinoid-rich solution and the tubular reactor.
