Method for extracting plant essential oil fragrance through water jet grinding and centrifugal membrane microwave distillation

Abstract

The invention relates to a method for extracting plant essential oil fragrance through water jet grinding and centrifugal membrane microwave distillation. The method comprises the following steps: S1, adding extraction raw materials of the ground plant essential oil fragrance into a mixing tank, adding water, stirring, and feeding the materials into a centrifugal machine; S2, conveying the separated heavy substance into a water jet mill for performing water jet grinding; S3, conveying the light substance solution obtained in the step S2 to a charging hole in the upper end of a low-temperature evaporation device, wherein the low-temperature evaporation device comprises a rotary conical disc and a fixed conical disc which are coaxially laminated; and the rotary conical disc is fixed on a central shaft to make a rotary motion; and S4, sucking gaseous aromatic oil substances into a condenser along with steam, and condensing into a liquid along with the water vapor; and allowing the aromatic oil substances to be separated from condensate water by virtue of a separator, thereby obtaining the plant essential oil fragrance in a liquid state. According to the method disclosed by the invention, high-quality plant essential oil fragrance is obtained by cell disruption and distillation extraction by virtue of a pure physical method.

Description

technical field [0001] The invention relates to the technical field of aromatic plant processing, and more specifically relates to a method for extracting plant essential oil aroma by water jet crushing and centrifugal membrane microwave distillation. Background technique [0002] With the improvement of the health level of modern society and people's recognition of the concept of "returning to nature", more and more attention has been paid to medicines, food, health care and skin care products using natural plants as raw materials. Among them, plant essential oils are not only pleasant In addition to the aroma components, most of them have strong penetrating power, enter the skin, assist body circulation, relieve nerves and other effects, and also have anti-oxidation, scavenging free radicals, soft skin, antibacterial and antibacterial, anti-aging, etc., in advocating "green consumption "Today, it is favored by people, so it is widely used in industries such as medical care...

AI Technical Summary

Problems solved by technology

[0026] Based on the above analysis, it can be seen that in this field, there is no wet grinding process at present. The force application mode of its pulverization not only has the functions of grinding and crushing, but also directly breaks the cells with stretching effect, and uses The method of distilling and extracting the aroma of plant essential oils in the form of a liquid film layer, heated by microwave irradiation
