METHOD OF PREPARING FIRST-CRYSTALLIZATION STRIKE Russian patent published in 2001 - IPC

FIELD: sugar industry. SUBSTANCE: mixture of syrup with melt liquor is concentrated to 82.0-83.0% solids, after which crystals are inoculated and grown, while crystal mass is simultaneously blown with steam to prevent formation of conglomerates. Crystal growth is continued as strike is concentrated to 88.0-88.5% solids at temperature 72.0-76.0 C, which is optimal for maximum sucrose crystallization. Strike is finally concentrated to 92.0-93.0% solids after preliminary addition of the second liquor, and process is carried out at temperature 66.0-72.0 corresponding to minimum viscosity. EFFECT: increased sugar crystal level and improved quality of sugar crystals in the first- crystallization strike, accelerated process, and reduced loss of sugar in crystallization zone.
