Abstract: A method of cannabinoid preservation includes separating a cannabinoid ethanol (EtOH) mixture from a cannabis extract through a filtration process; forming a slurry by combining a crystalline compound with the cannabinoid EtOH mixture; heating and agitating the slurry in a pressurized chamber to form a colloidal cannabinoid EtOH mixture; distributing the colloidal cannabinoid EtOH mixture into a tray to form an evenly distributed mixture layer; forming an evaporation vessel for the evenly distributed mixture layer through the attachment of a detachable cover to the tray; positioning and heating the evaporation vessel within a heating chamber; performing a rapid cools process as the evenly distributed mixture layer approaches approaches saturation temperature; repeating the rapid cooling process until crystal formation is detected within the evenly distributed mixture layer; and/or removing the evaporation vessel from the heating chamber upon detection of crystal formation.
