Abstract

The invention discloses a method and equipment for continuous countercurrent extraction of traditional Chinese medicine, belonging to the technical field of traditional Chinese medicine extraction. The first rotating part of the continuous countercurrent extraction equipment for traditional Chinese medicine is located at the center of the cylinder; an annular channel is formed between the first rotating part and the second rotating part and the inner wall of the cylinder, and the rotation of the first rotating part and the second rotating part The direction is opposite; the traditional Chinese medicine storage device is evenly distributed on the outer wall of the second rotating part, the top of the traditional Chinese medicine storage device is provided with a material inlet, the bottom is provided with a material outlet, and the material outlet is provided with a first electromagnetic valve. The surrounding wall of the traditional Chinese medicine storage device is provided with a plurality of permeable holes for the solvent to enter the interior of the traditional Chinese medicine storage device and contact with the traditional Chinese medicine; a plurality of traditional Chinese medicine stirring mechanisms are used to stir the medicine in the traditional Chinese medicine storage device. The traditional Chinese medicine continuous countercurrent extraction equipment of the present invention is compact in volume, simple in structure and lower in production cost, and overcomes the disadvantages of the spiral continuous countercurrent extraction equipment being bulky, long and large in loss.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine extraction, in particular to a method and equipment for continuous countercurrent extraction of traditional Chinese medicines. Background technique [0002] For the extraction of active ingredients of medicines, the traditional methods mainly include dipping method, decoction method, etc. Such extraction methods are mainly manual operation and static extraction, and the production efficiency is low. [0003] Continuous dynamic countercurrent extraction means that in the process of extraction, the material and solvent move continuously at the same time, but the movement method is opposite, through mechanical transmission, continuous quantitative feeding, so that the material and the solvent are fully contacted, the solvent in the equipment is continuously updated, and the production cycle can be shortened. It has the advantages of reducing the amount of solvent, and at the same...
