Extraction method of essential oil suitable for human body

Abstract

The invention discloses an extraction method of an essential oil suitable for a human body; the method comprises the following steps: a high pressure distilling step, simultaneously pressurizing and heating a high pressure distilling vessel filled with pure water and a to-be-extracted matter; a decompression step, decompressing the fluid formed by the high pressure distilling step, thus forming anormal pressure fluid; a cooling step, cooling the normal pressure fluid after the decompression step, and forming a condensed oil-water mixture liquid; an oil-water separation step, separating the oil-water mixture liquid into the essential oil and hydrosol, collecting the essential oil for usage, and gathering hydrosol into a hydrosol storage vessel; a hydrosol cycle import step, importing the hydrosol from the hydrosol storage vessel into the high pressure distilling vessel for re-extraction.

Description

technical field [0001] The present invention relates to an extraction method of essential oil, more specifically, relates to an extraction method of essential oil applicable to human body for wiping and drinking. Background technique [0002] At present, there are different methods of extracting essential oils on the market, such as "distillation extraction" and "supercritical extraction". [0003] Among them, "distillation extraction" is to use pure water to add "pre-distillate", and use pure water to heat and boil to dissolve the aroma components of "pre-distillate" in steam, and then condense the steam, separate oil and water to obtain essential oil and pure dew. [0004] "Supercritical extraction" uses high pressure and a solvent to destroy and dissolve the aroma components of the "pre-distillate" with a solvent, and then uses high pressure to extract the solvent in which the aroma components are dissolved. [0005] However, in "distillation and extraction", boiling pu...

Problems solved by technology

[0005] However, in "distillation and extraction", boiling pure water to dissolve the aroma components of the "pre-distillate" often cannot effectively extract the aroma components of the "pre-distillate", and the water after oil-water separation (also Hydrosol) will also contain a small amount of aroma components, which will lead to the problem of "incomplete extraction of pure water boiling"; while in the process of "supercritical extraction", it is dissolved by a solvent, which will cause aroma components broken problem
