ABSTRACT:
A method for refining a sugar liquor by cristobalite and an ion exchange resin, and a method for refining the sugar liquor by a novel ion exchange resin refining system, are disclosed. Cristobalite exhibits specific adsorbant properties for various colloidal or suspended substances, while the ion exchange resin exhibits superior decoloring and desalting properties with respect to colorants and salts. By combining refining by cristobalite and refining by the ion exchange resin, there is provided a sugar refining system whereby even non-washed sugar liquor may be refined. The ion exchange resin refining system of the present invention includes three series of adsorption towers. Each series basically consists of a strongly basic anion exchange resin and a weakly acidic cation exchange resin, and the towers of each of these three series are shifted in a sequence of the pre-stage adsorption tower, the adsorption tower for regeneration, the post-stage adsorption tower and again back to the pre-stage adsorption tower, so that the ability of the strongly basic anion exchange resin may be displayed to the utmost, while the colorant adsorbant properties and the deanionation properties may be exhibited effectively.
