Glycyrrhiza extracting solution clarification and concentration membrane system

Abstract

The invention discloses a glycyrrhiza extracting solution clarification and concentration membrane system. The glycyrrhiza extracting solution clarification and concentrated membrane system comprises a ceramic membrane clarification system and an RO (reverse osmosis) membrane concentrating system which are connected by a conveying pipeline; a glycyrrhiza crude extracting solution is pumped into the ceramic membrane clarification system for membrane system internal circulation to obtain a glycyrrhiza clarification solution; the obtained glycyrrhiza clarification solution is pumped into the RO membrane concentrating system by the conveying pipeline for concentration processing of the membrane system internal circulation to obtain dialysate; the dialysate enters a dialysate storage tank, and returns to the previous glycyrrhiza extracting working procedure for recycling; a concentration solution enters a concentration solution tank for subsequent processing treatment. The glycyrrhiza extracting solution clarification and concentration membrane system provided by the invention removes residual impurities in the glycyrrhiza extracting solution by utilizing the ceramic membrane clarification system so as to enrich effective ingredients; the RO membrane concentration system further purify and concentrate the clarification solution to obtain the high-quality glycyrrhiza concentration solution; the system operates at the normal temperature, has little loss of effective ingredients, and has no chemical change, and a product is not polluted because of the physical separation process.

Description

technical field [0001] The invention relates to equipment for extracting and concentrating licorice, in particular to a membrane system for clarifying and concentrating licorice extract. Background technique [0002] Extracting traditional Chinese medicine with water is the most widely used process step in traditional Chinese medicine preparations. Water is used as a solvent, which is cheap and easy to obtain, easy to operate, and low in production cost. However, the water extract of traditional Chinese medicine is generally large in volume, and there are a large number of macromolecular substances such as tannins, proteins, mucus, polysaccharides, pectin, and many particles, subparticles, and flocs in the solution. Most of them have no pharmacological effects. , and affect the quality of the product. How to scientifically and rationally purify, refine, and extract the essence from the extract, not only retain the active ingredients and curative effects of traditional Chine...
