Washing Sugar Crystals — Differential Dissolution of Corners, Edges and Faces



It has been common knowledge within the sugar industry that when sugar crystals are washed in a perforated basket centifuge the corners and edges quickly become rounded. From a systematic study of washing effects values for the relative sensitivity to dissolving of all zones of the sucrose crystal have been evaluated as well as the effects of growing additional faces with varying degrees of development. 


The fastest dissolving zones of a sugar crystal are the top and bottom right hand comers which on the average raw sugar crystal dissolve approximately twice as fast as the front face or orthopinacoid which is commonly the slowest dissolving portion and the most difficult area from which to wash away the residual film of impurities left by the receding mother liquor. Elongation of a crystal along the c-axis only aggravates the Problem of washing the orthopinacoid faces with increases of differentials of up to 40 or 50 % having been observed.
