Being called a kind of ten thousand years of product, vitamin is a kind of organic substance that is necessary to maintain animal life activities and it is also an important active substance to keep the body healthy. The application of membrane separation technology and continuous moving bed technology in many kinds of vitamins has achieved remarkable results: such as vitamin C, vitamin B2 and vitamin B12.

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

•   Ceramic membrane and flat membrane is used to replace the traditional filtration methods to clarify the fermentation liquor, improve the quality of filtrate and reduce the resin pollution and solvent dosage in the later process
•   The hyperfiltration membrane is used to remove protein and decoloration and improve 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 reduce unit consumption
•   The continuous chromatography is used to recycle and separate vitamin mother liquids
•   The membrane technology is used to recycle various mother liquors, waste liquids and reclaimed water reuse
