Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
