FIELD: sugar production technology. SUBSTANCE: process provides for cleaning of sugar crystals with washing fluid and drying of crystals. Fraction of crystals with size of 0.4-1.5 mm is separated prior to cleaning and is subjected to three-stage washing. Waste fluid is used as washing fluid at two of three stages, water having temperature of 25-40 C is used at third stage. Waste fluid is separated from crystals at each stage after washing and is recycled to preceding stage. Waste fluid recycled from second stage of washing to first stage is heated to temperature of 60-70 C and waste fluid recycled to second stage is heated to 45-55 C. EFFECT: simplified process of production of sugar from raw sugar, improved crystal structure of sugar.
