Abstract

An extracting and concentrating process for Chinese medicine includes such steps as loading raw Chinese-medicinal materials in extractor adding solvent, steam heating to obtain liquid, boiling evaporating in vacuum state, condensing the secondary vapour to obtain liquid, switching it to the liquid distributor of extractor, spraying it on the surface of Chinese-medicinal materials, and repeating said steps for extracting while concentrating. Its apparatus is composed of extractor, condenser, vacuum switching device, heater and evaporator. Its advantages are simple and compact structure, simple process, high extraction rate, less loss and low secondary pollution.

Description

technical field

[0001] The invention relates to a process and equipment for extracting and concentrating raw materials of Chinese medicinal materials. Background technique

[0002] With the wide application of dynamic extraction technology of traditional Chinese medicine, dynamic extraction-concentration unit equipment is also popularized accordingly. Check the Chinese ZL96118248.2 patent, which describes a heat reflux extraction and concentration process, which is characterized in that the process flow is: a. Extraction: put Chinese medicinal materials or food and other raw materials into the extraction tank, add water or organic solvents and use The steam is heated, and after boiling, the dilute drug solution is continuously pumped into the heater and evaporator through the suction filter tube. b. Concentration: After the liquid medicine enters the heater, close the steam valve of the extraction tank, open the steam valve of the heater, the heater is...
