METHOD OF MANUFACTURING RAW SUGAR MELT LIQUOR Russian patent published in 2008 - IPC C13F1/14 C13D3/00 C13F1/00 

FIELD: food products, chemistry.

SUBSTANCE: method implies melting raw sugar by hot sweet washed filtrate up to solids content of 53-57%, liming melt liquor, carbonatation up to pH of 9.2-9.5 and filtration. During melting raw sugar solution is treated by ozone-air mixture with the ozone concentration in the mixture equal to 5-15 g/nm³ and with the amount of ozone-air mixture equal to 3.0-4.5 nm³/m³ of the solution.

EFFECT: proposed method allows decreasing colour degree of the melt liquor, improving purification efficiency and reducing lime consumption as compared to the known process.
