A collection device for volatile substances of traditional Chinese medicine

Abstract

The invention discloses a multifunction collecting device for traditional Chinese medicine volatility materials. In the two processes of extraction and concentration of the traditional Chinese medicine, through a cooling device, water vapor with volatile traditional Chinese medicine active ingredients in the extraction and the concentration process is liquefied and passes through a volatile material separating device, according to the difference of the proportions of volatile materials and water, the separation purpose is achieved. In the extraction process, through opening a backwater switch, water liquid generated in the extraction process is automatically returned to an extraction tank, and the extraction effect is not influenced. In the concentration process, through closing the backwater switch, water liquid generated in the concentration process is discharged outside, and the concentration purpose is achieved. According to the device, an ingenious vacuum device is designed, and the extraction and the concentration of the traditional Chinese medicine under the condition of low pressure are achieved.

Description

technical field [0001] The invention relates to a device for collecting volatile substances with certain effects in Chinese medicine during the process of extracting and concentrating Chinese medicine, in particular to a collection device for volatile substances in Chinese medicine, which belongs to the equipment technology of Chinese medicine extraction, concentration or volatile oil extraction field. Background technique [0002] Most traditional Chinese medicines contain volatile components. Such volatile components have certain effects and are the material basis of the "nature and flavor" of traditional Chinese medicines. In particular, various volatile substances often play a divergent role in anti-surface medicines. The extraction process is inseparable from the preparation process of Chinese patent medicines and formula granules. In the modern Chinese medicine extraction process, the most commonly used method is water extraction. In order to extract completely, it is...

AI Technical Summary

Problems solved by technology

For the needs of preparations, it is often necessary to concentrate and dry these aqueous solutions, and this process also takes a long time. During the long-term heating and concentration project, the volatile components in traditional Chinese medicine that have certain curative effects evaporate with the water vapor, basically completely lost

Especially for traditional Chinese medicine formula granules, in addition to the special process requirements, the volatile effective substances contained in the original medicinal materials are generally lost, resulting in certain differences in the properties of traditional Chinese medicine formula granules compared with the original medicinal materials, which cannot fully reflect the original medicinal materials. at the same time, it does not conform to the traditional habit of clinical medicine in traditional Chinese medicine
