Bona Biology uses inorganic Ceramic membrane separation technology to filter protein, starch, pectin, tannin and other macromolecular substances as well as microorganisms from the extract of traditional Chinese medicine, while the effective components of traditional Chinese medicine are basically not intercepted; At the same time, according to the requirements of some liquid medicine treatment, the integrated membrane separation process organically combining Ceramic membrane separation technology and organic membrane ultrafiltration nanofiltration separation technology is adopted to form a stepped filtration separation refining liquid medicine, and the advantages of the two types of membrane separation are reasonably applied to the extraction and refining of traditional Chinese patent medicines and simple preparations.

Traditional Chinese medicine plays a very important role in the field of medicine. However, the components of traditional Chinese medicine are complex, and traditional methods for extracting and separating traditional Chinese medicine have shortcomings such as complex processes and low separation efficiency. Membrane separation technology can remove impurities from traditional Chinese medicine extracts, enrich effective parts or components, and is one of the high-tech technologies that urgently need to be promoted in the traditional Chinese medicine pharmaceutical industry. Therefore, in order to achieve the modernization of traditional Chinese medicine and truly promote it to the world market, it is imperative to apply and extract traditional Chinese medicine.

Traditional Chinese Medicine Extraction Membrane Separation and Concentration Technology:

The extract of Chinese herbal medicine is pretreated to remove some solid impurities, and then further clarified through membrane separation. The clarified solution is taken and enters the membrane concentration system. During the concentration and solvent removal process, some small molecule impurities are removed, and the concentrated solution continues to be processed through subsequent processes.

Advantages of Traditional Chinese Medicine Extraction Membrane Separation and Concentration:

1. The traditional Chinese medicine extraction solution is subjected to macromolecular ultrafiltration to remove macromolecular proteins, tannins, starch, plant fibers, polysaccharides, etc. from the solution, improving the clarity of the extraction solution, which is beneficial for protecting the subsequent concentration membrane, ensuring the concentration effect, and extending the service life of the concentration membrane.

2. Small molecule ultrafiltration can effectively remove impurities such as soluble macromolecular proteins, polysaccharides, and colloids, improving product purity and quality. The ultrafiltration membrane has a wide range of pore size and material selectivity, which can be analyzed and selected based on specific products.

3. Membrane concentration can effectively intercept target components and remove solvents to achieve concentration; The concentrated effluent is clear and transparent, and can be directly extracted, reused or discharged, saving water resources and reducing environmental pressure.

4. Membrane concentration is a type of room temperature concentration that can reduce the losses caused by the decomposition of active ingredients due to high temperature, ensuring product yield;

5. The concentration cost of membrane concentration is only about one-fifth of the cost of steam thermal concentration, greatly reducing the production cost of enterprises.

6. The membrane concentration process is closed, and if the extraction solvent is ethanol, it can reduce the loss of ethanol and save the cost investment caused by ethanol loss.
