METHOD OF OBTAINING CRYSTALLINE ANHYDRIDE GLUCOSE Russian patent published in 2014 - IPC C13K1/10 

FIELD: chemistry.

SUBSTANCE: method of obtaining crystalline anhydrite glucose includes obtaining a syrup, the syrup evaporation and its supply into a crystalliser, crystal nucleation in the syrup and growing crystalline mass with cooling massecuite, centrifugation of massecuite, to separate and wash crystals from the inetrcrystal liquid, drying of crystals. Crystal nucleation is carried out in an evaporation apparatus at the syrup concentration of DS 82-83%. Crystals of anhydrite glucose are added in an amount of 10-15 per 1 t of the syrup. Fixation of the formed nuclei of crystals in the evaporation apparatus is carried out until DS of massecuite is 84-85%. After that, massecuite is poured into the crystalliser. Growth of crystalline weight is performed in the crystalliser with cooling massecuite from 77-80°C to 45-50°C for 6-10 h.

EFFECT: invention makes it possible to considerably reduce duration of the crystallisation process, increase output of crystals from massecuite, and improve the quality of crystals by a degree of homogeneity and purity.
