METHOD FOR COMPLEX TREATMENT OF THICK SUGAR-CONTAINING SOLUTIONS TO EXTRACT SACCHAROSE Russian patent published in 2017 - IPC C13B35/00 

FIELD: food industry.

SUBSTANCE: invention relates to sugar industry. Method for complex treatment of thick sugar-containing solutions to extract saccharose provides for dissolution of thick sugar-containing solution by water or treated sugar juice. Then reagent treatment of the produced solution is carried out from non-sugars by introduction of reagents into it. Reagents are a mix of inorganic coagulant, acid reagent, cationic flocculant, a reagent accelerating flocculation process, a decoloring reagent, an anionic flocculant and lime milk. Solution is heated to temperature of 45-95°C, the produced residue of non-sugars is removed, solution is sent for electric dialysis treatment from salts of alkaline and rare earth metals and then introduced into the process flow of sugar production. Sugar-containing solution is dissolved down to 20-55% of dry substances. After electric dialysis treatment the treated solution is either thickened down to 60-75% of dry substances and introduced into technological flow of sugar production at the stage of fillmass B or C boiling, or introduced at the stage of B or C sugar remelt.

EFFECT: invention makes it possible to reduce treatment time, to improve extent of solution treatment from salts of alkaline and rare earth metals and to reduce its colour.
