Description

Efficient and energy-saving traditional Chinese medicine micro powder extraction and concentration system Technical Field The invention relates to the technical field of traditional Chinese medicine extraction and concentration, in particular to an efficient and energy-saving traditional Chinese medicine micro powder extraction and concentration system. Background The technology of extracting and concentrating traditional Chinese medicine is used as a key link of modern production of traditional Chinese medicine, and the technological level is directly related to medicine quality, energy consumption and production cost. Although the traditional method is widely applied, the traditional method has obvious limitations, and technical innovation is needed. Generally, the traditional Chinese medicine extraction and concentration mainly comprises liquid medicine extraction, medicine residue separation and liquid medicine concentration. In the traditional Chinese medicine extraction step, the traditional Chinese medicine extraction usually adopts a water decoction method, namely under normal pressure or pressurized condition, water or an organic solvent is used as a medium, and the dissolution of active ingredients is realized through long-time heating (such as decoction and reflux). The method relies on natural gas, coal and other energy sources for heating, and has the advantages of extremely high energy consumption and low thermal efficiency. More seriously, the cell structure of the medicinal material is not fully broken, and the cell wall barrier leads to insufficient dissolution rate and incomplete extraction of intracellular active ingredients (such as alkaloids, flavonoids and polysaccharides). For example, some volatile components (such as peppermint volatile oil and rhynchophylline) are easy to decompose or dissipate at high temperature for a long time, and the efficacy is remarkably reduced. Researches show that the utilization rate of the effective components of the traditional decoction method is generally lower than that of the traditional decoction method, so that the medicinal material resources are seriously wasted. In addition, the traditional process has the defects of more impurities (such as starch, protein and tannin) in the extracting solution, and heavy burden of subsequent impurity removal. In the liquid medicine concentrating step, the liquid medicine concentrating step is realized by adopting a water decoction concentrating or vacuum evaporation technology and evaporating a solvent through heating. The enterprises have to use natural gas for heating to meet the environmental protection requirement, and the energy consumption is huge. The evaporation process needs to maintain high temperature, so that not only is the thermosensitive components (such as glycosides and polysaccharides) degraded, but also the energy consumption and maintenance cost are further increased due to the problems of equipment scaling, reduced heat transfer efficiency and the like. For example, astragalus polysaccharides undergo Maillard reaction at high temperature concentration Shi Yifa, and the product color deepens and activity decreases. The traditional concentration process has low energy efficiency ratio, and the residual solvent is easy to cause environmental pollution. Disclosure of Invention Aiming at the defects in the prior art, the method aims to effectively solve the problems of high energy consumption, low efficiency, component destruction and the like of the traditional Chinese medicine extraction and concentration technology. The invention provides an efficient and energy-saving traditional Chinese medicine micro powder extraction and concentration system, which uses the combination of superfine grinding and membrane technology, and provides conditions for energy conservation, consumption reduction and efficient resource utilization in the traditional Chinese medicine industry by improving the cell wall breaking rate and the normal-temperature concentration efficiency. In order to achieve the above object, the present invention provides the following technical solutions. An efficient and energy-saving extraction and concentration system for traditional Chinese medicine micropowder, comprising: The superfine crusher is used for breaking the wall of the traditional Chinese medicinal materials into micro powder materials; A storage tank for receiving and storing the micro powder material of the ultra-micro crusher; a first micropowder extraction tank for receiving micropowder materials from the storage tank, and injecting an extraction solvent for extracting components of the micropowder materials; the first-stage separation device receives the material solution output by the first micro powder extraction tank and performs solid-liquid separation on the material solution; A first transfer tank for receiving the liquid medicine output by the first-stage separation device; the second-stage separation dev
