Traditional Chinese medicine extraction technology to extract compositae sauce herb extracts
mainly containing triterpene composition: chrysanthemum defeat sauce saponin A ~ F, ivy saponins, oleanolic acid, etc. Flavonoids ingredients: wood � � � grass, quercetin, rutin, prince 's-feather glycosides, different negundo jing glycosides, etc. ; Coumarin constituents: east belladonna lactone, seven leaf lactones, etc. ; Also contain volatile oil, cycloalkene ether terpenoids, sterols, etc. Raw material liquid mixed with the extracting agent fully contact, complete the solute mass transfer process;
weight according to certain proportion respectively from two two phase solution and feeding tube into the drum shell ring gap formed between the mixed zone, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer. Complete mixing and mass transfer process. Extraction and extraction residual phase separation process;
mixture under the action of vortex disk into the rotary drum, in the plate to form the bulkhead area, mixture quickly with synchronous rotary drum, in under the action of centrifugal force, the heavier than major phase fluid in the process of upward mobility and gradually away from the drum center on the drum wall; Small proportion of liquid phase gradually away from the drum wall and on to the center, after clarification of two phase fluid end respectively through their weir plate into the collection chamber and the tube was closed to derivation, respectively, to complete two phase separation process. From the extraction phase and extraction phase extractant recycling process.
usually use the method of distillation recycling extracting agent. Removal after extraction of proportion as the extractant extract; After removal from the extraction agent over extraction of proportion of extraction liquid.
