Cold precipitation tank for degreasing cannabidiol in industrial cannabis sativa

Abstract

The invention discloses a cold precipitation tank for degreased cannabidiol in industrial cannabis sativa, the cold precipitation tank comprises a cold precipitation tank body, a fine control blanking device, a support frame, a refrigerator, a controller, a material stirring and dissolving device and a dynamic wax removal filtering device, the support frame is arranged on the upper wall of the cold precipitation tank body, the fine control blanking device is arranged at the upper end of the support frame, and the refrigerator, the controller, the material stirring and dissolving device and the dynamic wax removal filtering device are arranged in the cold precipitation tank body; and the material stirring and dissolving device comprises a stirring and filtering tank, a stirring motor, an electric push rod, a motor fixing plate, a rotating shaft, stirring blades, a lower fixing frame, a bearing plate, a lower connecting rod and a lower baffle. The invention belongs to the technical field of extraction and separation of chemical components of natural plants, and particularly provides the cold precipitation tank for degreased cannabidiol in industrial cannabis sativa, which is convenient for accurately controlling the ratio of ethanol to an extract, facilitating uniform mixing and dissolving of materials and effectively separating filtrate and flocculent floating objects.

Description

technical field [0001] The invention belongs to the technical field of extraction and separation of natural phytochemical components, and specifically refers to a cooling tank for defatting cannabidiol in industrial hemp. Background technique [0002] Cannabis is an annual herb with important medicinal value, belonging to the genus Cannabis subfamily Cannabis in the family Moraceae. There are three main active ingredients in cannabis plant extracts: cannabidiol CBD, cannabinol CBN, and tetrahydrocannabinoid THC, among which THC is an addictive ingredient. The hallucinogenic effect of marijuana plants on humans is mainly determined by the concentration of THC, and varieties with THC<0.3% have no psychoactive effect. Therefore, the European Commission has formulated a unified standard that the THC content in dry cannabis products can not be higher than 0.3%, which is called "industrial hemp". [0003] At present, there are more than 80 kinds of cannabinoids isolated from ...

AI Technical Summary

Problems solved by technology

[0005] The existing cold sinking tank has poor dewaxing effect, long degreasing time, low efficiency, and the mesh is easily blocked by too much wax accumulated on the filter, but the generation of flocculent floating objects when the CBD extract is low temperature is a continuous process. Therefore, it is imminent to seek a cold sink tank that can be dynamically dewaxed and separated, and is not easy to be blocked.
