inTraditional Chinese Medicine extractionDuring the process, we mostly use water extraction and alcohol precipitation, alcohol extraction and water precipitation processes, combined with single effect, multi effect concentration, vacuum concentration and other methods and techniques to concentrate and remove impurities from the extracted liquid, in order to obtain the effective ingredients and products we need. In the production process, many filtration methods are often used, such as the dead end filtration method with titanium rods and plate frames. Due to the large amount of soluble macromolecular impurities in the liquid medicine, such as macromolecular proteins, pigments, tannins, polysaccharides, etc., traditional filtration methods can only achieve temporary clarification of the liquid medicine. Over time, these soluble impurities will still precipitate and form a precipitate, which we call "secondary precipitation", greatly affecting product quality, sensory quality, shelf life, and even drug efficacy.
The use of ultrafiltration membrane technology and membrane system has the following advantages in the production process of traditional Chinese medicine preparations:
1. Short production cycle;2. Low consumption of filtering consumables;
3. Long service life and low production cost;
4. Molecular level filtration, high precision, can effectively remove impurities such as macromolecular proteins, pigments, tannins, resins, etc., and maintain product stability;
5. Guaranteed filtration, which can effectively control the heat source and ensure product quality;
6. The equipment has a small footprint, automated control, and is easy to operate and control;
7. The separation membrane adopts cross flow filtration method, which is not easy to clog and has a slow attenuation of filtration speed;
Membrane separation components are easy to clean, regenerate, maintain, and have a long service life.
