AI Technical Summary

Problems solved by technology

However, supercritical fluid extraction also has shortcomings: this technology is suitable for the extraction of lipophilic and small molecular weight substances, and the extraction effect on active ingredients with large polarity or large molecular weight is poor
This separation technology is relatively mature, but it is still difficult to promote in industrialization. The main reason is that the output is too small, and the conditions for large-scale production are not yet available, and the production cost is relatively high.

Embodiment Construction

[0035] See Table 1 for examples of microfiltration membranes for purification of traditional Chinese medicines of the present invention.

[0036] Table 1:

[0037]

[0038] The pH regulator in the above-mentioned embodiment can adopt Al 2 (SO 4 ) 3 or NaOH etc.

[0039] Chinese medicine purification microfiltration membrane of the present invention can adopt known following method to make:

[0040] 1. Ingredients in proportion;

[0041] 2. Beat the wood fiber and cotton fiber in the beater until the degree of percussion is 40-70;

[0042] 3. Put other raw materials into the three-dimensional vibration mill and grind them finely. According to the weight percentage, the raw materials with a particle size of less than 1 μm are about 30%, the raw materials with a particle size of 1 μm to 5 μm are about 30%, and the raw materials with a particle size of 5 μm to 10 μm are 40%. about;

[0043] 4. Put the raw materials in steps 2 and 3 into the mixing tank and mix evenly;

Abstract

A micron-filtering membrane for purifying Chinese medicine is proportionally prepared from wooden fibers, cotton fibers, activated carbon, sepiolite, pearlite, zeolite, diatomite, bentone, polyacrylamide epoxy hexapropane, and pH regulator.

Description

Technical field: [0001] The invention relates to a traditional Chinese medicine purification microfiltration membrane used in the traditional Chinese medicine production process, which can well separate effective components and ineffective components. Background technique: [0002] The extraction of traditional Chinese medicine is generally carried out in aqueous solution, which not only extracts active ingredients, but also extracts more ineffective ingredients, such as tannins, gums, etc., thus forming the "black, large, and rough" of Chinese medicine boiled agents. At present, the water extraction and alcohol precipitation process is used. Although the current situation of "black, large, and coarse" has been improved, the alcohol precipitation technology cannot effectively remove invalid impurities such as tannins and gums, and often results in varying degrees of loss of active ingredients. , it is difficult to meet the quality requirements, the production cycle is long, ...
