Problems solved by technology

[0009] The technical problem to be solved by the present invention is to overcome the traditional decarboxylation drying method for increasing the CBD content of industrial hemp flowers and / or leaves, which is to dry at high temperature under dry conditions, and there are side decarboxylation, CBD side degradation and broken rings, high temperature, and large energy consumption. , long cycle, no comprehensive utilization of industrial hemp flower and / or leaf aromatic water in the drying and decarboxylation process, so that the downstream products do not have the unique aroma of industrial hemp, and cannot highlight the shortcomings of product characteristics, etc.

Embodiment 1

[0040] (1) Get 10kg of fresh industrial hemp flowers and leaves, cut into sections, open the airtight door of the vacuum microwave dryer, put the sectioned industrial hemp flowers and leaves into the drying tray in the vacuum microwave dryer, the drying tray is not Cover the lid, close the airtight door tightly, and seal a condenser on the vacuum tube of the vacuum microwave dryer, and a fragrant water receiver is sealed at the lower end of the condenser.

[0041] (2) Turn on the vacuum, adjust the vacuum exhaust valve, maintain the vacuum at -0.005MPa ~ -0.03MPa, then tighten the airtight door, start the cooling water circulation in the condenser on the vacuum tube, the cooling water temperature is 1 ° C ~ 4 ° C, open Microwaves are used to extract aromatic water and dry materials. The microwave temperature is maintained at 50°C to 70°C. The mixture of volatile components in the vacuum tube and water vapor (water vapor generated by heating fresh industrial hemp flowers and lea...

Embodiment 2

[0047] Embodiment 2 is the same as Embodiment 1 except that the specific parameters of the following steps are different.

[0048] Step (2) The vacuum degree is maintained at -0.04Mpa to -0.05MPa, the cooling water temperature is 5°C to 8°C, and the microwave temperature is maintained at 40°C to 65°C.

[0049] Step (3) Vacuum microwave extraction and drying until the moisture content of the material is 24% by sampling and testing, and 4.45 L of industrial hemp aromatic water is collected, which does not contain CBD components after testing.

[0050] Step (4) opens the airtight door, puts a lid on the drying tray that detects the moisture content of 24% industrial hemp flowers and leaves, and then puts a lid on the drying tray that detects the moisture content of 24% industrial hemp flowers and leaves The drying dish with the lid is placed in a vacuum microwave desiccator, the airtight door is closed and screwed tightly. When the microwave is turned on for the wet heat decarbo...

Embodiment 3

[0054] Embodiment 3 is the same as Embodiment 1 except that the specific parameters of the following steps are different.

[0055] Step (2) The vacuum degree is maintained at -0.07MPa~-0.1Mpa. The cooling water temperature is 9°C to 10°C. The microwave temperature is maintained at 35°C to 45°C

[0056] Step (3) Vacuum microwave extraction and drying until the material moisture is 15%. 3.73L of the collected industrial hemp aromatic water has been tested and does not contain CBD ingredients.

[0057] Step (4) Open the airtight door, put a lid on the drying tray with detected moisture content of 15% industrial hemp flowers and leaves, and then cover the drying tray with detected moisture content of 15% industrial hemp flowers and leaves The drying dish with the lid is placed in a vacuum microwave desiccator, the airtight door is closed and screwed tightly. When the microwave is turned on for the wet heat decarboxylation reaction, the temperature is raised to the microwave te...

Abstract

The invention provides a pretreatment drying method for simultaneously extracting industrial hemp aromatic water and increasing the CBD content of an industrial hemp raw material, and belongs to the technical field of industrial hemp processing. The method mainly comprises the following steps: (1) taking industrial hemp flowers and / or leaves, performing vacuum microwave extraction and drying, and condensing and collecting aromatic water; (2) carrying out wet heat decarboxylation by microwaves to improve the CBD content; and (3) conducting vacuum microwave drying. According to the method, in the process of drying the industrial hemp flowers and / or leaves, the aromatic water is comprehensively utilized and extracted under the low-temperature and low-oxygen conditions and is added into industrial hemp downstream products, and the original fragrance and flavor of the industrial hemp are reserved; and meanwhile, drying of the industrial hemp is completed, CBDA decarboxylation is achieved, and the dried industrial flower and / or leaf raw material with the CBD content increased is obtained.

Description

technical field [0001] The invention belongs to the technical field of industrial hemp flower and / or leaf processing, and specifically relates to a pretreatment drying method for simultaneously extracting industrial hemp aromatic water and increasing the CBD content of industrial hemp raw materials. Background technique [0002] Industrial hemp, also known as hemp (Hemp), is a hemp with very low (<0.3%) content of Tetrahydrocannabinol (THC). Its seeds, fibers, leaves and other by-products are widely used in textiles, materials, Cosmetic, pharmaceutical and food industries. Cannabidiol (CBD) is an important non-psychoactive substance in hemp. It can not only antagonize the hallucinogenic effect of THC, but also has anti-oxidation, anti-tumor, anti-inflammatory, anti-anxiety, anti-spasm, and anti-drug resistance. Sexual epilepsy and other physiological activities. [0003] Industrial hemp flowers and / or leaves contain a large amount of volatile components, which have a sp...
