CRYSTALLINE WHITE SUGAR PRODUCTION METHOD Russian patent published in 2014 - IPC C13B30/02 

FIELD: food industry.

SUBSTANCE: method envisages second crystallisation sugar melt production by way of sugar dilution with 80-90°C syrup in centrifuges till dry substances concentration is equal to 70-76% with subsequent treatment in a cavitator at a transmission rate equal to 10-15 m/s. Then one performs crystals formation in the process of boiling out first, second crystallisation fillmass and a crystalline base of third crystallisation fillmass using seed fillmass. Seed fillmass has crystals sized 0.120-0.160 mm. Seed fillmass for first crystallisation fillmass is prepared based on second crystallisation sugar melt and is boiled out till dry substances content is equal to 92.5% in the mixture of syrup with melt. Seed fillmass for second crystallisation fillmass is boiled out till dry substances content is equal to 94.0%. The crystalline base of third crystallisation fillmass is prepared based on third crystallisation sugar melt and then boiled out till dry substances content is equal to 94.5%. Then first crystallisation fillmass is centrifuged with separation into crystalline white sugar and runoffs.

EFFECT: invention allows to increase yield and enhance the quality of crystalline white sugar due to fillmasses purity regulation.
