Abstract

Sugar (sucrose or glucose) is crystallized by passing a hot supersaturated syrup to a continuous screw extruder such that progressive nucleation of the syrup is induced during a mean residence time of below 25 seconds and then discharging the nucleated syrup onto a surface, e.g. a conveyor belt, to crystallise without agitation.
