Ganoderma lucidum polysaccharide is a component extracted from Ganoderma lucidum with various pharmacological activities and health benefits. It is commonly extracted using hot water extraction (or assisted by ultrasound), with the water volume typically being 40 times the weight of the Ganoderma lucidum itself. During the extraction process, not only is Ganoderma lucidum polysaccharide obtained, but also various soluble components such as plant fibers, colloids, trace elements, plant proteins, as well as insoluble Ganoderma lucidum residues. Therefore, a certain filtration and separation method is required to filter and remove impurities from the extract. The filtrate is then concentrated, dehydrated, and small molecules are removed to purify and enrich Ganoderma lucidum polysaccharide, reduce the volume for subsequent drying, and lower the investment in drying equipment and energy consumption.
Chongqing Jiahe Filtration Technology Co., Ltd. has long been committed to the development and equipment application of processes such as extraction, filtration, refining, decolorization, concentration, and drying of natural plants. By integrating advanced membrane separation technology, these processes can be completed under molecular-level, room-temperature physical, and low-energy consumption conditions.
As a macromolecular active substance, Ganoderma lucidum polysaccharide requires microfiltration equipment for clarification and impurity removal after the extraction process. The selection of microfiltration precision is delicate: if the filtration precision is too low, the extract appears turbid with high impurity content; if it is too high, the loss rate of polysaccharides increases. The JH-MF type polysaccharide microfiltration equipment, with precision selected based on our company's industry application experience, is well-suited for filtering and removing impurities from polysaccharides.
Our ultimate goal is to obtain Ganoderma lucidum polysaccharide powder. In the extraction stage, to achieve a high extraction rate of polysaccharides, the water-to-material ratio is often very high, resulting in a large volume of extract. After microfiltration with JH-MF, the JH-NF membrane concentration equipment is used for dehydration and small molecule removal, enriching Ganoderma lucidum polysaccharide while further purifying it. Polysaccharide membrane concentration technology operates at room temperature physically, without affecting the active components of polysaccharides, preserving the biological activity of polysaccharide molecules. It offers high concentration efficiency, with dehydration energy consumption as low as 8-15 yuan per ton of water (electricity-driven). The membrane concentration system operates online and is cleaned online without disassembling membrane elements, reducing manual labor intensity.
