Membrane separation technology is an emerging high-efficiency separation technology with a molecular weight cut-off range of 100Da-300kDa. By utilizing the principle of selective sieving, it can address challenges such as clarification, impurity removal, concentration, and purification of fermentation broth, while simultaneously achieving clean production, energy conservation, and consumption reduction. The process flow of membrane separation for fermentation broth is as follows:
       Fermentation broth → Membrane filtration (clarification, recovery of cells) → Membrane concentration (dehydration, desalination, removal of small molecular impurities) → Subsequent processes
       Advantages of fermentation broth membrane separation technology:
       1. Separation at room temperature with mild conditions and no component damage, particularly suitable for heat-sensitive substances;
       2. Pure physical filtration, no phase change or quality change, preserving active ingredients;
       3. High filtration precision with uniform pore size distribution, enabling purification and concentration of active ingredients in fermentation broth;
       4. Simple system operation, short process flow, easy cleaning and maintenance;
       5. After filtration and concentration of fermentation broth, it not only reduces volume, speeds up column loading time, and minimizes resin consumption but also allows for the simultaneous recovery of mycelium, improving production efficiency, resin lifespan, and regeneration cycle;
       6. Cross-flow system design eliminates the need for filter aids, thoroughly resolving pollution and clogging issues;
       7. Modular system design facilitates filter media replacement, with built-in online regeneration cleaning and discharge devices, reducing labor intensity and production costs while enhancing production efficiency;
       8. Use of 304 or 316L stainless steel sanitary materials, compliant with QS quality standards.
       Typical applications:
         1. Clarification and separation of fermentation sugar solutions;
         2. Impurity removal, concentration, and desalination of vitamins and antibiotics;
         3. Clarification, removal of mycelium, concentration, and dehydration of enzyme preparations;
         4. Various types of biological fermentation broths.
