Abstract:

        We investigated the influences of glucose solution concentration, diatomite model, volume of mixed decolorants, ratio of activated charcoal and diatomite on decoloring efficiency with the running time in the deckleboard of mixture of glucose raw materials and decolorants as a parameter to increase decoloring efficiency and to decrease the costs in the production of medical anhydrous glucose. Orthogonal experiment shows that the parameter can reach the maximum in the conditions of 69% glucose liquid concentration, 700# diatomite, 7‰ volume of decolorants and 5:2 ratio of activated charcoal and diatomite. Moreover, the employment of mixed decolorants decreases the amount of activated charcoal and filter cloth by almost 30%, so production costs are reduced.

Key words: ecolorization, anhydrous glucose, mixed decolorants, orthogonal experiment design
