Abstract:
     The invention provides a sugar-making decolorizing purifier, containing a high-molecular weight aluminum polymer shown by the general formula: Ala(OH)bXc, where X is selected from one or several ones of monovalent or bivalent acid radical ions: Cl-, ClO-, ClO4-, Br-, NO3-, SO42-, H2PO4-, HPO42-, HCOO- and CH3COO-, and the ratio of a to b to c = 1 : 2.1 : 0.9 -1 : 2.9 : 0.1. It contains 20-60% macromolecular polymer or colloid particles with molecular weight 5X10 to the power 4-1X10 to the power 5, 40-80% multinuclear hydroxy aluminic complex polymer with molecular weight less than 1X10 to the power 4, and 0-10% hexaccordianted hydrated aluminum ions or mononuclear hydroxy aluminic complex. Its basicity is 70-93%. It can be applied to decolorizing and purifying process of different-stage and different-color value sugar juices. It has high decoloration ratio, good effect of eliminate colloids, improving sugar product quality and can directly produce refined white sugars by sugarcane, sugar beets, etc.
