Abstract

The invention discloses an essential oil extraction process method, which is applied to the technical field of plant essential oil extraction and is used for improving the extraction efficiency and yield of essential oil. The process method provided by the invention comprises the following steps of: freezing raw materials in refrigeration equipment into a solid state by controlling the refrigeration time of the refrigeration equipment; grinding the solid raw materials to obtain solid slag, and heating the solid slag to obtain a mixed primary pulp; carrying out material separation on the mixedprimary pulp to obtain a solid residue wet material and a mixed solution; controlling the state of carbon dioxide in the high-pressure boiler by controlling the pressure and temperature of the high-pressure boiler, and extracting the residue wet material in the high-pressure boiler by using the carbon dioxide in different states to obtain first essential oil; carrying out distillation treatment onthe mixed solution through a distillation boiler to obtain second essential oil; and mixing the first essential oil and the second essential oil to obtain the essential oil extracted from the raw materials.

Description

technical field [0001] The invention relates to the technical field of plant essential oil extraction, in particular to a process for extracting essential oil. Background technique [0002] Extracting traditional Chinese medicine components from pomelo (flower) leaves is the most important traditional Chinese medicine production process. The extraction methods of traditional Chinese herbal medicine components in my country mainly include ultra-high pressure extraction, steam distillation, supercritical extraction, enzymatic hydrolysis, semi-bionic extraction, vacuum freeze-drying, ultrasonic extraction, high-speed countercurrent chromatography separation technology, macroporous adsorption resin separation and purification technology, Tissue crushing extraction method and enzymatic extraction technology, etc. However, the current method of extracting traditional Chinese medicine components based on pomelo leaves is relatively inefficient, and the extracted chemical components...
