Extraction of Grey Tree Flowers

Gray tree flowers have good health benefits and high medicinal value. Gray tree flower polysaccharides are an extract from gray tree flowers, composed of heteropolymer complexes of pectin, glucose, xylose, fucose, xylose, mannose, lactulose, and a small amount of protein.

Coarse filter the fermentation broth of polysaccharides from the ash tree flower, effectively removing most of the solid impurities in the polysaccharide solution. The crude filtrate is further filtered to obtain a high-purity polysaccharide solution; Finally, a ultrafiltration membrane device with a molecular weight of 5-10w is selected to remove impurities and concentrate the polysaccharide solution, resulting in a high-purity concentrated solution of ash tree flower polysaccharides.

Process flow of grey tree flower membrane separation technology

Grey tree flower polysaccharide fermentation broth → coarse filtration → membrane microfiltration → membrane ultrafiltration → subsequent processes

Advantages of Grey Tree Flower Membrane Separation Technology

1. Cross flow operation design, no need to add filter aids, can solve the problem of pollution blockage;

2. Both membrane filtration and membrane concentration processes are pure physical processes, without phase change, and retain the effective ingredients of the product;

3. The world's advanced nanofilm technology materials have strong selectivity and thorough separation of impurities;

4. Design online regeneration cleaning and sewage discharge devices to reduce labor intensity and production costs, and improve production efficiency;

5. Select 304 or 316L stainless steel sanitary grade materials that meet QS and GMP requirements;

6. The membrane element has a large filling area and a small footprint, which facilitates the technological transformation, expansion or new construction projects of old factories, and can effectively reduce production costs and investment.
