Abstract

The invention relates to a continuous dynamic countercurrent extracting process for an effective component of plants, which is characterized in that a discharge hatch of a batching bunker is connected to a feed inlet of a pre-dip device through a pipeline, a discharge hatch of the pre-dip device is connected to a feed inlet of an extruding extractor through the pipeline, a discharge hatch of the extruding extractor is connected to a feed inlet of a countercurrent dynamic extractor, a discharge hatch of the countercurrent dynamic extractor is provided on the countercurrent dynamic extractor, a solvent inlet of the pre-dip device is provided on the pre-dip device, a solvent inlet of the extruding extractor is provided on the extruding extractor, a solvent inlet of the countercurrent dynamic extractor is provided on the countercurrent dynamic extractor, and a liquid outlet of the pre-dip device is connected to a second storage tank through the pipeline. The continuous dynamic countercurrent extracting process for the effective component of plant enables countercurrent relative movement of plant material and a solvent, therefore the material and the solvent can fully mixed and contacted, the extraction power is effectively increased, the extraction time can be shortened, the raw material and the solvent can be continuously and automatically separated.

Description

Technical field: [0001] The invention relates to a device for continuous dynamic countercurrent extraction of plant active ingredients and a process thereof. Background technique: [0002] At present, the extraction process commonly used in the plant extraction industry is a single-stage batch operation and a multi-stage series contact operation, and the extraction device used is a leaching tank (and a combination of multiple tanks). Because in the single-stage intermittent and multi-stage series contact operation, the material to be leached does not move, but only the solvent flows countercurrently, or the movement of the raw material does not play a significant role in the extraction; therefore, there is no relationship between the raw material and the solvent. Full and effective contact, large mass transfer resistance, and an ideal concentration gradient cannot be formed throughout the extraction process. In terms of process flow, when the last stage of leaching is over,...
