Disclosed herein is a method for continuously preparing crystalline cannabinoid particles. The method includes 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 includes flowing the cannabinoid-rich solution into a continuous stirred-tank reactor (CSTR) in a continuous manner, mixing the cannabinoid-rich solution under turbulent mixing conditions to form a plurality of crystalline cannabinoid particles and a cannabinoid-depleted solution within the CSTR, and discharging the plurality of crystalline cannabinoid particles and the cannabinoid-depleted solution from the CSTR in a continuous manner to provide a flow rate through the CSTR. The method includes separating crystalline cannabinoid particles from the plurality of crystalline cannabinoid particles and the cannabinoid-depleted solution in a continuous manner.
