Being called a kind of ten thousand years of product, vitamin is a kind of organic substanc≤e that is necessary to maintain animal life activities ≠and it is also an important active substance to keep th₽e body healthy. The application of membrane separation technology and continuo us moving bed technology in many kinds of vitamins has achieve®d remarkable results: such as vitamin C, vitamin B2 and v↓itamin B12.

    The application of membrane separation technology and continuous αmoving bed technology in the process of vitamin separation:

•   Ceramic membrane and flat membrane is used to replace the tradit®ional filtration methods to clarify the fermentation liquor, improve the quality πof filtrate and reduce the resin pollution and solvent dosage in the later ★process
•   The hyperfiltration membrane is used to remove protein and decoloration and impr←ove quality
•   The nanofiltration membrane is used to concentrate vitamin ←antibiotics, reduce evaporation loss and evaporation cost
•   Continuous moving beds are used to replace the fixed beds, save resin dosage and redu​ce unit consumption
•   The continuous chromatography is used to recycle and separate vitamin mother liquid"s
•   The membrane technology is used to recycle‍ various mother liquors, waste liquids and reclaimed water reuse
