Continuous concentration device of traditional Chinese medicine thermal-refluxing extracting liquid

Abstract

The invention relates to a Chinese medicine hot reflux extracting solution continuous enrichment device and the extraction, enrichment an evaporation of Chinese medicine. The device comprises an extracting tank (1), a filter (2), a middle liquid medicine tank (3), a liquid medicine pump (4), a rotary thin film evaporating concentrator (5), a concentrated solution receiving tank (6), a first condenser (7), a second condenser (8), a solvent receiving tank (9) and a vacuum system (10). A liquid medicine outlet of the extracting tank (1) is communicated with a liquid medicine inlet of the filter(2); the liquid medicine outlet of the filter is communicated with the liquid medicine inlet of the middle liquid medicine tank (3); the liquid medicine outlet of the middle liquid medicine tank is communicated with the liquid medicine outlet of the liquid medicine pump (4); the liquid medicine outlet of the liquid medicine pump is communicated with the liquid medicine inlet of the rotary thin film evaporating concentrator (5); steam produced in the extracting tank (1) is sent to the first condenser(7); the condensed hot fluid in the first condenser(7) is switched into the extracting tank (1); and a high density concentration solution extractum outlet of the rotary thin film evaporating concentrator(5) is communicated with the concentrated solution receiving tank (6). The device is characterized by short heating time, low temperature, stable evaporation capacity and comparatively small amount of solvent, which can realize continuous evaporation and concentration.

Description

(1) Technical field [0001] The invention relates to a device for continuously concentrating traditional Chinese medicine hot reflux extracts. It is mainly used for the extraction, concentration and evaporation of traditional Chinese medicine in the pharmaceutical, health care products and food industries. It belongs to the technical field of traditional Chinese medicine extraction and concentration equipment. (2) Background technology [0002] Extraction, concentration and evaporation processes are a frequently involved operating unit in the pharmaceutical, nutraceutical and food industries. Especially in the process of processing the extracts of Chinese herbal medicines, concentration is an essential process. In terms of extract concentration methods, traditional single-effect evaporation and double-effect evaporation, and external circulation (or pot type) intermittent concentration are still used by most Chinese medicine factories. In the process of concentrating the e...
