Problems solved by technology

However, no matter what method is used to extract traditional Chinese medicine, most of the current extraction processes of traditional Chinese medicine are unitary extraction, and there is no effective means for effective monitoring of the extraction process and scientific extraction end point judgment. The extraction efficiency is low, the energy consumption is large, and the quality Uncontrollable, unable to produce continuously

Abstract

According to the continuous countercurrent extraction equipment and method for the traditional Chinese medicine, a single-screw device is used for conveying medicinal materials, and heating, ultrasonic and stirring devices are arranged for continuous countercurrent extraction of the traditional Chinese medicine; the second near infrared spectrum sampling device is used for monitoring liquid medicine to monitor the continuous countercurrent extraction process in real time, then the traditional Chinese medicine extraction end point is determined, and the first near infrared spectrum sampling device is used for monitoring extracted medicine residues to judge the medicine extraction end point. When it is detected that extraction of the medicinal materials is completed, medicine residues are continuously discharged through the single-screw device, in the extraction process, a solvent and the medicinal materials continuously enter the extraction tank body, a traditional Chinese medicine extracting solution and the medicine residues are continuously discharged out of the extraction tank body, and efficient, rapid and economical continuous extraction of the traditional Chinese medicine is achieved.

Description

technical field [0001] The invention relates to the technical field of separation and extraction of traditional Chinese medicines, in particular to a device and method for continuous countercurrent extraction of traditional Chinese medicines. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the production process of modern traditional Chinese medicine, extraction is a key step in the process of "removing crude oil and extracting essence", and it is a key link in the pharmaceutical process of traditional Chinese medicine. The extraction methods of traditional Chinese medicine include decoction, percolation, dipping, etc. With the development of the modernization of Chinese medicine, the modern Chinese medicine extraction process has gradually developed new methods such as ultrasonic extraction, microwave extraction, and supercritical flui...
