Winterization equipment for CBD purification and winterization method thereof

Abstract

The invention discloses winterization equipment for CBD purification and a winterization method thereof. The winterization equipment comprises a feeding pipeline, crystallization winterization bins, crystal growing winterization bins, a discharging pipeline, a filter, a refrigeration system, a refrigeration pipeline and a refrigeration backflow pipeline; a first feeding port and a first refrigerant outlet are formed in the top of the crystallization winterization bin; a first discharging port and a first refrigerant inlet are formed in the bottom of each crystallization winterization bin; the refrigeration pipeline and the refrigeration backflow pipeline are both connected with the refrigeration system; and a second feeding port and a second refrigerant outlet are formed in the top of each crystal growing winterization bin, and a second discharging port and a second refrigerant inlet are formed in the bottom of each crystal growing winterization bin. One crystallization winterization bin and one crystal growing winterization bin form a group of winterization devices, and the winterization equipment comprises at least two groups of winterization devices; the equipment and the method are good in impurity removal effect and wide in application range, the continuity of the winterization process is realized, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of CBD purification, and in particular relates to a winterization device and a winterization method for CBD purification. Background technique [0002] Cannabidiol (CBD), a cannabinoid found in the cannabis plant, is different from another cannabinoid tetrahydrocannabinol (THC) found in the cannabis plant. CBD has no psychoactive effects, but under the premise of ensuring the extraction rate, There will be waxes on the surface of industrial hemp plants that will dissolve, increasing the amount of impurities, which will also cause pressure and influence on the subsequent separation of CBD. Therefore, removing the waxes dissolved in the solvent is to improve the accuracy of subsequent CBD separations and reduce CBD. The key to separation difficulty. Usually, winterization technology is used to complete the impurity removal process. On the premise of ensuring the basic conditions of winterization, the precipit...

AI Technical Summary

Problems solved by technology

[0004] The first technical problem to be solved by the present invention is to provide a winterization equipment for CBD purification, which realizes continuous feeding and continuous discharge, and solves the problem that winterization cannot be continuously produced in the past. The volume of the equipment can be adjusted and expanded according to the volume of winterized materials, and the use range is wider, which solves the problem that the volume of winterized equipment in the past is fixed and cannot adapt to the different volumes of materials that need to be winterized. This equipment does not use stirring equipment , which solves the problem that the stirring paddles used in the winterization equipment are easy to break the crystallized crystals, and the effect of purification and impurity removal is better

[0005] The second technical problem to be solved by the present invention is to provide a winterization method, which utilizes the above-mentioned winterization equipment, and solves the problem that the past winterization methods cannot continuously winterize and cannot adapt to the need for winterization. The problem of different volumes also solves the problem that the stirring paddles are used to easily break the crystallized crystals during winterization
