Abstract

The dynamic circulation staged continuous countercurrent extraction process is characterized by that it has several extraction units, the effective component contents in effective materials of all the extraction units and effective component contents in the solvents successively are decreased progressively, and its complete extraction process is continuously implemented by stages whose stage number is idential to the number of extraction units, and every unit can respectively independently make extraction operation. When the extraction process of some stage is completed, the unit whose effective component is completely extracted, it can make residue-removing and charging operations.

Description

technical field

[0001] The invention relates to a technology for extracting effective ingredients (such as medicinal ingredients) from animals and plants, specifically a continuous countercurrent extraction technology in a dynamic circulation stage, which can be widely used in the fields of pharmacy, chemical industry, food processing and the like. Background technique

[0002] The existing traditional Chinese medicine extraction process usually uses extraction methods such as decoction, dipping, and heat reflux. Most of them use a single extraction tank for extraction operations. Generally, 2 to 3 extractions are required. The amount of solvent used is as high as 10 times the weight of the medicinal material. The extraction temperature up to the boiling point of the solvent. Mainly there are the following problems: ①Excessive temperature will lead to the excessive cracking and gelatinization of starch and the loss of azeotropic distillation components wi...
