A recently granted patent (Publication Number: US11925907B2) discloses a method for producing crystalline cannabinoid particles in a continuous mode. The process involves preparing a cannabinoid-rich solution, inducing it to a supersaturated state, flowing it into a continuous stirred-tank reactor (CSTR), mixing it under turbulent conditions to form crystalline particles, and separating them from the solution. The method specifies the use of specific cannabinoids such as THC, CBD, and others, along with various solvents and operating conditions like temperature, viscosity, and fluid density.

Furthermore, the patent claims include additional steps like cooling the solution, using baffles to redirect flow, adding seed crystals, and evaporating the solution to reduce volume. The method aims to achieve a continuous production process for crystalline cannabinoid particles with precise control over the formation and separation of the particles. By defining critical parameters like Reynolds number and energy dissipation rate, the process ensures efficient mixing and particle size control. Overall, the patent outlines a comprehensive method for the continuous production of crystalline cannabinoids, catering to the growing demand for standardized cannabinoid products in various industries.
