Plant aromatic essential oil preparation and extraction process

Abstract

The invention belongs to the technical field of essential oil production, and particularly relates to a plant aromatic essential oil preparation and extraction process which comprises the following steps: 1, steam heating: putting a plant containing aromatic substances into a distiller, and introducing water vapor into the distiller from the bottom of the distiller; 2, condensing and standing: introducing the water vapor mixed with the aromatic essential oil component into a condenser, and standing to obtain an oil-water mixed solution; 3, filling and shaking: filling the oil-water mixed solution into a separating funnel, and then shaking the separating funnel; and 4, layered extraction: standing the shaken separating funnel, and carrying out layered extraction after the oil-water mixed solution is layered; The step 3 is completed by adopting a plant aromatic essential oil preparation and extraction device in a matching manner. The uniformity of the filling amount when the oil-water mixed solution is filled into the separating funnel is improved, meanwhile, the mixing effect of the oil-water mixed solution is improved, and the situation that the separating funnel is broken is avoided.

Description

technical field [0001] The invention belongs to the technical field of essential oil production, and in particular relates to a preparation and extraction process of plant aromatic essential oil. Background technique [0002] Plant aromatic essential oils are volatile aromatic substances extracted from the flowers, leaves, stems, roots or fruits of plants through steam distillation, extrusion, cold soaking or solvent extraction. Extracting plant aromatic essential oils by steam distillation is to put the plant parts containing aromatic substances into a still, and inject water vapor at the bottom of the still. The aromatic essential oil components in the plant evaporate with the water vapor, and enter the condenser with the water vapor, so that the steam is cooled and converted into an oil-water mixture, and finally the oil-water mixture is extracted in layers. Before the oil-water mixture is subjected to layered extraction, it is necessary to fill the oil-water mixture int...

Problems solved by technology

[0004] The invention provides a preparation and extraction process of plant aromatic essential oils, the purpose of which is to solve the following problems that exist when the oil-water mixture is filled and shaken: (1) Since the oil-water mixture has a certain viscosity, each time the oil-water mixture is filled into the separating funnel After the oil-water mixture is finished, part of the oil-water mixture adhering to the liquid outlet will continue to fall into the separatory funnel during the process of closing the liquid outlet, resulting in uneven filling volume; (2) During the process of shaking the separatory funnel , the oil-water mixture will produce a certain amount of volatilization, which will cause the air pressure in the separatory funnel to increase, which will not only affect the full mixing of the oil-water mixture, but also cause the separatory funnel to rupture in severe cases
