Description

Cold settling tank for defatted cannabidiol in industrial hemp

Technical Field

The utility model belongs to the technical field of natural plant chemical composition extraction and separation, in particular to a cold settling tank for degreased cannabidiol in industrial hemp.

Background

Cannabis is an annual herb plant of significant medicinal value, belonging to the family Moraceae, the subfamily Cannabis. The main active ingredients of the hemp plant extract are three types: cannabidiol CBD, cannabinol CBN, tetrahydrocannabis THC, wherein THC is an addictive component. The hemp plant is mainly dependent on the concentration of THC, and the variety with THC less than 0.3% has no mental activity. Therefore, the European Union Committee sets a unified standard, and the THC content in the dry product of the planted hemp can not be higher than 0.3 percent, namely the dry product is called as 'industrial hemp'.

At present, more than 80 cannabinoids separated from cannabis are available, mainly comprising cannabidiol CBD, tetrahydrocannabis THC, cannabinol CBN, cannabigerol CBC and the like, and the research finds that CBD can block THC from influencing the human nervous system and has important pharmacological activity. In addition, in recent years, the research finds that CBD has a series of physiological functions of sedation and hypnosis, epilepsy treatment, neuroprotection, multiple sclerosis, rheumatoid arthritis, tumor treatment and the like, and is a natural active component with great application prospects in the fields of medicines and the like.

A cold precipitation tank, namely a cooling precipitation tank, is used in the dewaxing step of the process for extracting the degreased cannabidiol from the industrial hemp, and the crude extract of the extract generated after crushing, baking and leaching is dissolved by using ethanol solution, then the crude extract is frozen at the temperature of between 40 ℃ below zero and 5 ℃ below zero and filtered at the temperature, and the filtrate is collected to obtain CBDV enrichment;

the existing cryoprecipitation tank has poor dewaxing effect, long degreasing time and low efficiency, meshes are easy to be blocked due to excessive wax accumulated on a filter screen, but flocculent floaters are generated at low temperature of a CBD extract and are a continuous process, so that the cryoprecipitation tank which can be dynamically dewaxed and separated and is not easy to be blocked is urgently sought.
