Continuous-circulating extracting concentration method of Chinese medicineand equipment thereof

Abstract

The invention relates to a traditional medicine continuous circulate extracting concentrating method and relative device, wherein said device comprises drug extracting pot, solvent pot, and distill pot. The inventive method comprises that: adding extracting solvent into distill pot, heating, condensing via tube, flowing into extracting pot, immerging drug, reaching some level, adsorbing extracted liquid into distill pot, circulating until complete extraction; heating extracted liquid in distill pot, condensing solvent, guiding into one storage pot, entering into next process, and the solvent in storage pot can be extracted again. The invention concentrates after extraction, with high efficiency, reduced energy consumption and saved time, while the solvent can be saved more than 50%.

Description

technical field

[0001] The invention relates to a method and equipment for extracting traditional Chinese medicine, in particular to a method and equipment for continuously extracting traditional Chinese medicine. Background technique

[0002] The existing traditional Chinese medicine preparation technology usually adopts the intermittent extraction method, that is, put the traditional Chinese medicine in the extraction tank, add water and heat it for a certain period of time, then release the medicinal liquid, and then extract it 2-3 times in the same way, and finally pour it out Medicinal dregs, this extraction method is inefficient and takes a long time, and has been replaced by a new method. For example, in recent years, some pharmaceutical factories have adopted the dynamic warming extraction method. The equipment includes percolators, multi-functional extraction tanks, etc. The extraction rate of active ingredients is relatively high, and the extraction process does no...
