specific Embodiment

[0051] Extraction process: (see figure 2 )

[0052] The roasted industrial hemp mosaic raw materials enter the soaking pool 3 through the feeding port, and the soaking pool 3 is added with the specified dose of 6# solvent oil through its solvent inlet, soaked at room temperature for more than 2 hours, and enter the first solvent pool 4 through the solvent outlet B in turn And the second solvent pool 5, in the second solvent pool 5, utilize steam heating method to remove most of 6# solvent oil, obtain industrial hemp raw material extract, 6# solvent oil is reclaimed by condensation pool 1 and volatile oil solvent tank 2 successively And recycle, can repeatedly input in the soaking pool 3 and use.

[0053] Flow chart of industrial hemp essential oil: (see figure 1 )

[0054] The industrial hemp raw material extract liquid enters the ultrasonic stirring tank 6 through the extract liquid inlet, heats to remove the remaining 6# solvent, adds absolute ethanol, and ultrasonically...

Abstract

The invention discloses an extraction method and an extraction device for cannabidiol-enriched industrial hemp essential oil. By adopting devices such as a screening machine, an oven, a soaking tank, a rotary evaporator, an ultrasonic agitation tank, a butterfly centrifuge, a first climbing-film evaporator, a proportioning tank, a pressurized chromatography silica gel column, an eluate tank, a second climbing-film evaporator, a rotary evaporator, a finished product tank and a solvent recovery tank which are sequentially connected by virtue of pipelines, industrial hemps are stepwise subjected to the operation steps comprising screening, baking, extracting, re-treating, filtering, monitoring, sampling, chromatography and concentrating to obtain the finished product and the effective component cannabidiol-enriched industrial hemp essential oil is finally extracted. By virtue of the extraction device disclosed by the invention, the defects of low efficiency, large consumption and inconvenience in scale production of the conventional process are overcome, the semi-finished product containing tetrahydrocannabinol in the processing does not artificially contact and flow, is legal, safe and efficient, the process method is simple and can be easily promoted and the product has high purity, complete active ingredients and low cost.

Description

technical field [0001] The invention relates to the field of plant extraction, in particular to a method for extracting cannabidiol-rich industrial hemp essential oil, and also relates to extraction equipment used in the process of producing cannabidiol-rich industrial hemp essential oil. Background technique [0002] At present, the extraction method of industrial hemp essential oil mainly adopts the extraction method of soaking in organic solvents. Since the extract components are contained in its tissue cells, the periphery of the cells is a layer of cell walls composed of cellulose, hemicellulose and pectin. The inside is the protoplasm. During the pretreatment process, the physiological functions of the protoplast are destroyed by heating, ultrasonic and other operations, so that the active ingredients and other soluble substances in the industrial hemp cells penetrate to the outside of the cells. Therefore, we need to separate out what we need. The active ingredients m...
