METHOD OF SEPARATING FIRST CRYSTALLISATION FILL MASS Russian patent published in 2016 - IPC C13B30/06 

FIELD: chemistry.

SUBSTANCE: disclosed method comprises dividing first crystallisation fillmass, which involves loading of fillmass from a receiving crystalliser tank in rotor filtering centrifuge periodic action, first runoff separation from sugar crystals, washing with second runoff separation and direction of separated effluents by segregator into separate collectors. Fillmass loaded in centrifuge rotor, is preliminarily diluted with its first runoff with addition of distilled monoglyceride in amount of 0.04-0.06 % of weight of fillmass. First runoff separation is accompanied by entry in centrifuge rotor moisture-saturated air temperature higher than fillmass at 3-5 ° C, washing sugar crystals with second runoff separation is started 15-25 s after loading fillmass in centrifuge rotor water temperature 80-95 °C, wherein it is preliminarily dissolved hydrogen peroxide in amount of 0.002-0.010 % of weight of sugar. Segregator is switched to second runoff 10-12 s after start of supply of wash water on a layer of sugar crystals with direction of first and second runoff in separate collectors.

EFFECT: method provides higher yield of sugar from centrifuge, shorter cycle of centrifuging fillmass and improved sugar quality.
