METHOD FOR PRODUCTION OF FIRST CRYSTALLISATION FILLMASS Russian patent published in 2013 - IPC C13B30/00 

FIELD: food industry.

SUBSTANCE: method envisages syrup condensation in a vacuum apparatus, crystals formation, growing, removal of a part of fillmass from the vacuum apparatus, centrifugation of this part of fillmass with separation into sugar and runoff, the runoff return into the vacuum apparatus and the remaining part boiling out. Sugar crystals sized 0.15-0.20 mm are self-initiated according to the Braunschweig method; then the syrup is condensed till oversaturation is equal to 1.17-1.19; re-formed crystallisation centres are dissolved with water or juice-and-syrup intakes till oversaturation is equal to 1.10-1.12. The treated crystals are grown in the fillmass till dry substances content is equal to 91.0-91.5%. One performs fillmass removal from the vacuum apparatus in an amount of 30-45% of the total weight. The remaining fillmass in the vacuum apparatus is diluted with syrup till dry substances content is equal to 89-90%; repeated crystals growing is performed by way of syrup delivery into the vacuum apparatus; the runoff of the separated fillmass part is returned into the vacuum apparatus after syrup introduction termination. The remaining fillmass in the vacuum apparatus is boiled out till dry substances content is equal to 92.0-92.5%.

EFFECT: increase of sugar sand yield from first crystallisation fillmass.
