Problems solved by technology

[0004] Existing conventional techniques for extracting cannabidiol generally use ordinary extraction tanks for solvent extraction. The disadvantage is that the CBDA (cannabidiolic acid) in the raw material can be converted into CBD (cannabidiol) after high-temperature decarboxylation, which leads to the extraction yield. Not high, and the existing technology generally has the defects of low efficiency, low purity, and low production efficiency

Embodiment 1

[0084] Such as figure 1 As shown, a kind of CBD extracting method that the present embodiment provides, specifically comprises the following steps:

[0085] (1) Sorting / crushing: remove impurities from industrial hemp raw materials (including industrial hemp flowers and / or leaves), and then grind them to 50-120 mesh for later use.

[0086] (2) Drying and decarboxylation: put the pulverized industrial hemp raw material in the extraction tank, and heat the temperature in the extraction tank to 120-180° C. for 1-1.5 hours of decarboxylation reaction by means of oil bath heating;

[0087] (3) Continuous countercurrent extraction: the temperature in the extraction tank is lowered below the boiling point of the extraction solvent, the extraction solvent is injected into the extraction tank, the raw material of industrial hemp is kept warm and extracted, and the extract is obtained; among them, multiple extraction tanks are connected in series end to end Set, the solvent extraction ...

Embodiment 2

[0108] Such as figure 2 As shown, the present invention also discloses a CBD extracting device, which includes: A module, B module and C module.

[0109] The decarboxylation and extraction in module A are carried out in six 210×1000mm circular extraction tanks T1, T2, T3, T4, T5, T6, and 100L extraction solvent storage tanks VB and 200L are connected at the inlet end of the series extraction tanks / h infusion pump P1, the end of the series extraction tank is connected to a 100L extract storage tank VA, and the extract storage tank VA is connected to a 100L decolorization tank T1; the extract is decolorized and 0.5M 2 After being filtered by the plate and frame filter B1, it enters the 200L / h scraper concentrator N1, and the solvent recovered by the scraper concentrator returns to the solvent storage tank VB through the pipeline G6. The extracted extract obtained enters the extraction process through the valve K4. The heat source for the concentration, decarboxylation and ex...

Abstract

The invention provides a CBD extraction device and method. The extraction device comprises a module A, a module B and a module C, wherein the module A comprises a decarboxylation extraction unit for drying and decarboxylating an industrial hemp raw material and carrying out solvent extraction on the de-carboxylated industrial hemp raw material, a de-colorization unit for carrying out a de-colorization treatment on the extract, and a primary concentration unit for carrying out primary concentration on the decolorized extract; the module B is used for refining industrial hemp seed oil; and the module C is used for realizing separation and purification of CBD. The production process is enclosed and integrated, the product purity is high, the operation is convenient, the cost is low, and the method is suitable for preparing a CBD product with a purity of 99% or more from industrial hemp.

Description

technical field [0001] The invention relates to the technical field of extraction and purification of plant components, in particular to a fast, fully enclosed, process-based high-purity CBD extraction device and method. Background technique [0002] Marijuana (Cannabis sativa L.) is an annual herb of the Cannabis family Cannabis genus. The phenolic substances isolated from the cannabis plant mainly include THC (tetrahydrocannabinol, tetrahydrocannabinol), CBD (cannabidiol, cannabidiol), CBC ( Cannabichromene, cannabichromene), CBN (cannabinol, cannabidiol), CBG (cannabigerol, cannabigerol), etc., among which CBD has high medicinal value. GW UK has developed Epidiolex (a liquid formulation containing CBD) for the treatment of onset epilepsy in children. [0003] In 1988, the United Nations clearly stipulated that industrial hemp with a THC content of less than 0.3% in the flower leaves of hemp during the growth period can be legally carried out in large-scale planting and i...
