采用UF法精制I+G产品

Refining of I+G production by ultrafiltration

采用截留分子量 (MWCO) 1万的卷式超滤膜和截留分子量 (MWCO) 6 0 0 0的中空纤维超滤膜 ,去除I +G粗品液中影响I +G产品透光的色素、大分子蛋白及可溶性胶体蛋白 ,不需加碳、压滤等工序 ,产品透光合格率达 10 0 % ,产品透光的合格稳定性较现有生产工艺大大提高 ,该工艺不仅可以省去加碳压滤等工序 。

Spiral ultrafiltration membrane(MWCO 10 000) and hollow fiber ultrafiltration membrane (MWCO 6 000) modules were used to refine I+G.Pigment,macrosoluble albumen and soluble colloid albumen,which influenced the I+G transmittance,were removed by ultrafiltration process.The production eligibility without adding carbon and filtration can reach 100%.The stability of production eligibility was higher than that in existence.
