Application method of molecular short-range distiller for extracting cannabidiol from medical marijuana

Abstract

The invention discloses an application method of a molecular (short-range) distiller for extracting cannabidiol in medical marijuana, which comprises the following steps of: 1, selecting medical marijuana extract for later use; 2, the extract is put into a feeding tank for heating, and extract solution is pumped into a molecular short-range distiller by a feeding pump when the extract melts and can freely flow, and the extract solution is distilled by a molecular (short-range) distiller. Vacuumizing the molecular short-range distiller through a vacuum pump, controlling the stirring speed, andsimultaneously introducing cooling / heating medium into the condenser in the molecular short-range distiller; 3, collecting the cannabidiol in the material collecting tank 2, collecting the extract residue in the material collecting tank 1, and simultaneously introducing heat medium into the material collecting tank 1 and the jacket of the material collecting tank 2 to carry out heating and heat preservation; 4, heating the freezing medium in a cold well, and obtaining a small amount of tetrahydrocannabinol and a solvent in the material collecting tank 3; 5, when the extract in the feeding tankis almost finished, adding extract into the feeding tank until the extract is finished, and ending the experiment / production.

Description

Technical field [0001] The invention relates to the medical field, in particular to an application method for extracting cannabidiol from medical marijuana by a molecular short-path still. Background technique [0002] Molecular (short-path) distillation is different from traditional distillation which relies on the separation principle of boiling point difference, but relies on the difference in the mean free path of the molecular motion of different substances to achieve separation. The distillation process is when the liquid mixture flows along the heating plate and is heated under a certain pressure condition. The light and heavy molecules will escape from the liquid surface and enter the gas phase. Because the free paths of light and heavy molecules are different, they are different. The molecules of the substance move at different distances after escaping from the liquid surface. If a condensing plate can be properly set up (the distance between the evaporation area and th...
