Micro-filtration membrane cleaning compound used for clarifying compound traditional Chinese medicine extract

Abstract

The invention discloses a micro-filtration membrane cleaning compound used for clarifying a compound traditional Chinese medicine extract, which relates to the technical field of a micro-filtration membrane. The micro-filtration membrane cleaning compound comprises the following raw materials in parts by weight: 15-25 parts of glyceryl monostearate-polyglutamic acid-laurinol, 5-10 parts of sesbania gum, 5-10 parts of black rice flour, 1-5 parts of rice bran wax, 0.5-2 parts of sodium citrate, 0.5-2 parts of hydrolytic polymaleic anhydride, 0.05-0.5 parts of hydrogenated castor oil, 0.05-0.5 parts of N-methylolacrylamide, and 250-400 parts of deionized water. The prepared cleaning compound is used for cleaning the micro-filtration membrane for clarifying compound traditional Chinese medicine extract, the pollutants on the micro-filtration membrane can be rapidly removed through flushing by the cleaning compound, the penetration flux of the compound traditional Chinese medicine extract by the micro-filtration membrane can be effectively recovered, the clarification speed of the compound traditional Chinese medicine extract is guaranteed, and the usage life of the micro-filtration membrane is prolonged.

Description

Technical field: [0001] The invention relates to the technical field of microfiltration membranes, in particular to a microfiltration membrane cleaning agent for clarification of compound Chinese medicine extracts. Background technique: [0002] At present, one of the urgent problems to be solved in the modernization of the Chinese medicine pharmaceutical industry is the clarification of the Chinese medicine extract. The traditional clarification process is not only low in efficiency, but also causes serious loss of the total solid content and active ingredients of traditional Chinese medicine. It is difficult for traditional Chinese medicine preparations to reflect the characteristics of high efficiency, quick effect and long-term effect. [0003] In recent years, the application of membrane separation technology in the pharmaceutical industry has attracted more and more attention. People have conducted a lot of research on the extraction of various single and compound Chinese med...

Problems solved by technology

Membrane cleaning usually includes physical methods and chemical methods. At present, it is difficult to restore the permeation flux of the membrane to a satisfactory effect only by existing physical cleaning methods, while conventional chemical cleaning methods use strong acids and strong alkalis. Alternate cleaning, and adding oxidants and surfactants, etc. Although this method can quickly remove membrane pollutants, it is easy to cause corrosion to the membrane and shorten the service life of the membrane

[0004] Due to the complex composition of the compound Chinese medicine extract, it is easy to pollute the microfiltration membrane used for clarification. At the same time, in order to avoid the various defects of the above-mentioned conventional cleaning methods, our company has developed a microfiltration membrane cleaning agent for the clarification of the compound Chinese medicine extract. The cleaning agent effectively removes the pollutants on the microfiltration membrane through emulsification, dispersion, adsorption, and flocculation, so as to restore the separation performance of the microfiltration membrane, thereby ensuring its permeation flux and prolonging its service life
