Extraction device and method of extracting active ingredient from solid matter

Abstract

The invention relates to an extracting device for extracting active ingredients in solid matter and a method for extracting active ingredients in solid matter. The extraction device includes an extraction tower and a vaporization kettle for vaporizing the solvent. The extraction tower has a cavity, and the cavity is used for the heat exchange between the solvent gas and the solid extract therein, which is partially condensed into a solvent, and further dissolves the effective substance in the solid extract. Components, and the solvent gas sent into the cavity at the same time drives the extraction liquid and solid extract in the cavity to turbulence. The method comprises: vaporizing the initial solvent to form a solvent gas; sending the solvent gas into an extraction tower containing a solid extract, and the solvent gas sent into the extraction tower is partially condensed to form a solvent after exchanging heat with the solid extract, and further dissolves the solid extract. The active ingredients in the extract and the solvent gas sent to the extraction tower at the same time drive the extraction liquid and solids in the extraction tower to be turbulent by the extract. The above method and extraction device have a wide range of applications and can efficiently extract active ingredients in solid substances.

Description

technical field [0001] The invention relates to the field of solid substance extraction, in particular to an extraction device for extracting active ingredients in solid substances and a method for extracting active ingredients in solid substances. Background technique [0002] At present, solvent extraction methods for active ingredients in solid substances, especially for natural active ingredients in Chinese herbal medicines and spices, include maceration, percolation, decoction, reflux extraction, and continuous reflux extraction. method, supercritical fluid extraction, ultrasonic extraction, microwave extraction, dynamic countercurrent extraction, etc. [0003] Among them, maceration, percolation, and decoction are traditional extraction processes. In these processes, affected by the concentration of the active ingredients in the extract, the driving force for the diffusion and mass transfer of the active ingredients in the solid to the solution is small, and the extra...
