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 fillmass boiling out. Sugar crystals are initiated in an amount of 10-12 units per 1 mm of the trial lens surface length; the sugar crystals growing is performed till dry substances content in the fillmass is equal to 90-90.5%. One performs fillmass removal from the vacuum apparatus in an amount of 40-50% of the total weight of the fillmass and proceeds with delivering into the receiving fillmass stirrer where sucrose crystallisation is performed by way of cooling till the temperature is equal to 68-70°C during 60-90 minutes with subsequent separation into sugar and runoff in the centrifuges. The runoff is represented by a mixture of two runoffs i.e. inter-crystal runoff and runoff from crystals washing with hot water delivered for sugar crystals washing in an amount of 1.5-2.0% of the fillmass weight with hydrogen peroxide addition in an amount of 0.002-0.010% of sugar sand weight. The remaining fillmass in the vacuum apparatus is diluted with syrup till dry substances content is equal to 88-89%; repeated crystals growing is performed where the runoff return is to be used after termination of the fillmass boiling out on the syrup. The fillmass is condensed till dry substances content is equal to 92-92.5%.

EFFECT: method ensures yield of sugar crystals of high quality due to deeper depletion of fillmass inter-crystal solution.
