Ceramic membrane filtration is an advanced membrane separation technology, using porous ceramic material as membrane carrier, realizing solid-liquid separation, clarification, concentration and other processes through microporous sieving action. It has many advantages such as high temperature resistance, acid and alkali resistance, organic solvent resistance, high mechanical strength, good chemical stability, long service life, strong regeneration performance, etc. It can effectively remove suspended solids, colloids, large molecules of proteins, tannins, starch, plant fibers, polysaccharides, and other impurities in the extracted solution, and at the same time, achieve the concentration of the active ingredients, improve the purity and quality of the product, which is getting more and more widely used in the field of plant extraction.

Application of ceramic membrane filtration in bitter melon extracts
In the traditional production process of bitter melon extract, the appearance, color and odor of the finished product are unstable, and the content of active ingredients is low. The traditional filtration and impurity removal process adopts plate and frame or diatomaceous earth filtration, which is incomplete in removing impurities and has low product purity; the traditional concentration process adopts low-temperature concentration, which is characterized by large volume of extract, high energy consumption for concentration, increased cost, and long time of concentration, serious loss of active ingredients, and low yield of the product.
Advantages of Ceramic Membrane Filtration
1. Efficient removal of impurities and clarification: Using the microporous sieving effect of ceramic membrane, the macromolecular impurities in the bitter melon extract are completely retained at the molecular level, such as plant proteins, colloids, fibers, etc., so as to improve the clarity of the extract, and make the appearance, color and odor more stable, effectively solving the turbidity problem of the traditional filtration method, and providing a good raw material base for the subsequent processing and application.
2. Protecting the active ingredients: The ceramic membrane filtration process is carried out at room temperature or lower temperature, avoiding the destruction of heat-sensitive active ingredients in bitter melon extract by high temperature, such as bitter melon pigment, glucagon-like peptides, etc., retaining the biological activity and medicinal value of bitter melon extract to the maximum extent, and improving the quality and efficacy of the product.
3. Reduce the difficulty of concentration: After ceramic membrane filtration, the impurity content of bitter melon extract is greatly reduced, and when subsequently concentrated, the viscosity of the concentrate can be effectively reduced to reduce the energy consumption and time in the concentration process, improve the concentration efficiency, and also help to prevent the loss of the active ingredients in the concentration process, to ensure the yield of the product.
4. Stable and reliable system: The ceramic membrane is resistant to flushing, can be backwashed and sterilized at high temperature, is not easy to be contaminated and clogged, has a long service life and low maintenance cost. Its high degree of automation, easy to operate, easy to control and manage, can realize stable industrialized production, and bring good economic benefits for the enterprise.

Application of ceramic membrane filtration in kidney bean extracts
Kidney bean extracts are usually rich in proteins, polysaccharides, flavonoids and other bioactive components, which have certain health and medicinal values. In the extraction process, it is also necessary to face the key problems of how to improve the purity of the extract, remove impurities, and concentrate the active ingredients in order to meet the requirements of subsequent preparations and applications.
1. Optimize the quality of the extracted liquid: By choosing the appropriate pore size and operating parameters of the ceramic membrane, it can effectively remove the suspended matter, residue, microorganisms and other impurities in the extracted liquid of kidney bean, so that the extracted liquid becomes clarified and transparent, and improves its degree of clarification and stability, and provides high-quality raw material liquid for the subsequent deep processing.
2. Concentration of active ingredients: ceramic membrane can retain large molecules of active ingredients in the extract, such as proteins, polysaccharides, etc., while allowing water and small molecules of impurities to pass through, in order to achieve the clarification of the extract at the same time, but also the concentration of the active ingredients, to improve the content and quality of the extract, reduce the subsequent drying and other processes to reduce the load, reduce production costs.
3. Reduce the subsequent processing procedures: Compared with the traditional extraction process, ceramic membrane filtration technology can realize the double function of removing impurities and concentration in one step operation, reducing the process links in the production process, reducing the complexity of the operation and the production risk, and at the same time avoiding the loss of the product and contamination that may be caused by the multiple transfers and treatments, improving the efficiency of the entire production process and economy.
