METHOD FOR CENTRIFUGAL SEPARATION OF FIRST CRYSTALLISATION FILLMASS IN SUGAR PRODUCTION Russian patent published in 2017 - IPC C13B30/10 

FIELD: food industry.

SUBSTANCE: invention relates to sugar industry. A method of separating the first crystallization fillmass comprising loading the fillmass in the filtering batch centrifuge rotor, separating the first runoff from the sugar crystals, washing them with separating the second runoff and slight drying the sugar crystals before discharging them from the rotor. Previously in the fillmass charged to the rotor soft distilled monoglyceride is administered, heated to the fillmass temperature, in an amount of 0.002-0.006% of its weight. Thereafter, the mixture is loosened with the syrup of the concentration of 60-65%, until the dry substances content of the fillmass is equal to 91.7-92.5%. Thereafter, the centrifuge rotor is filled with the fillmass, simultaneously with administering air saturated with moisture, with the temperature of 5-7°C higher than that of the fillmass. Wherein after separating the first runoff bulk of the fillmass layer, washing sugar crystals is started. It is carried out in two steps: first, by means of sugar containing solution, then with hot water mixed with ozone.

EFFECT: invention provides the increased yield of white crystal sugar from the centrifuge and the improvement of its quality parameters.
