Cosmetic plant essence extraction method

Abstract

The invention relates to a cosmetic plant essence extraction method. Distillation extraction equipment is used in the method. The distillation extraction equipment comprises a shell, a material containing frame, a ventilation device and a condensation device, the specific method for preparing the plant essence by adopting the extraction equipment comprises the following steps: crushing raw materials, introducing steam, distilling, extracting, condensing, collecting, standing and layering, wherein the ventilation device comprises a ventilation pipe, a rotating mechanism, a lifting pipe, a lifting plate, a dispersion frame, a connecting rod, a lifting rod, a lifting frame, a lifting cam and a driving motor. Steam is continuously sprayed to materials in the material containing frame through the ventilation device; essential oil gas is cooled into essential oil liquid through the condensing device to be collected, the vent pipe can rotate in a reciprocating mode in the gas spraying process, the gas spraying range is enlarged, and meanwhile the gas spraying position of the vent pipe is intermittently changed through vertical reciprocating motion between the vent pipe and the lifting pipe so as to increase the steam spraying distance.

Description

Technical field [0001] The invention relates to the technical field of cosmetics, in particular to a method for extracting cosmetic plant essences. Background technique [0002] Extraction, also known as solvent extraction or liquid-liquid extraction, also known as extraction, uses the difference in solubility or partition coefficient of a substance in two immiscible (or slightly soluble) solvents to transfer solute substances from one solvent Into another solvent. [0003] Plant essence is a high-concentration substance extracted from plants by means of extraction. It is also called plant essential oil. Because of its hydrophilic nature, it is more convenient to add and use. Many essences can stimulate blood circulation, remove toxins and help different The active ingredient is evenly distributed in the deep layer of the skin, so it is often used to make cosmetics. [0004] At present, most plant essences are prepared by steam distillation extraction method, and there are some pro...

AI Technical Summary

Problems solved by technology

[0005] (1) Most of the steam enters from the bottom, and the material on the upper layer has less contact with the steam than the material on the lower layer, and the position of the vent hole is fixed, and the heating speed of the material not directly facing the vent hole is obviously slower, and the heated Inhomogeneity directly leads to uneven distillation speed of essential oil;

[0006] (2) When the essential oil vapor is cooled by the spiral condenser tube, some essential oils will adhere to the inner wall of the condenser tube. Mixing with other batches of essential oils, resulting in lower purity of other batches of essential oils
