Description

Dynamic extraction tank for extracting cannabidiol from industrial hemp

Technical Field

The invention belongs to the technical field of plant component extraction and purification, and particularly relates to a dynamic extraction tank for extracting cannabidiol from 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.

Since CBD has a large amount of biological activity and medicinal value, the extraction of CBD from cannabis sativa leaves has a wide market prospect. But the structure of the jar is generally drawn including a jar body now, is provided with the heating intermediate layer on the external wall of jar, and the upper portion of jar body is equipped with the feed inlet, the lower part is equipped with liquid outlet and slag notch, and its theory of operation is: the method comprises the steps of putting medicinal materials and a solvent (generally water or ethanol) into an extraction tank through a feeding hole for mixing, introducing steam into a heating interlayer or directly introducing steam into the tank for heating the mixture, gradually separating out the medicinal materials from active ingredients in the heating process, dissolving the medicinal materials into the solvent to form a liquid medicine, heating for a period of time, finishing extraction, directly discharging the liquid medicine from a liquid outlet and collecting the liquid medicine, and simultaneously pumping out part of the liquid medicine by a pump and sending the liquid medicine back to the feeding hole in the upper part of the tank to form forced circulation of the liquid medicine so as to improve the content of the active ingredients in the final liquid medicine. But the current dynamic extraction jar is difficult for evenly extracting the material, and is inconvenient to slag tap.
