Abstract
A process for crystallizing an aqueous fructose feed stream uses an alcohol mixture which may be crystallized in either a vacuum evaporator chamber or a cooled atmospheric pressure crystallizer. Various cooling cycles are described. When the atmospheric pressure crystallizer is used, the mixture is stirred continuously; therefore, the temperature of the mixture is held low enough to cause crystals to form, but also high enough not to be too viscous to stir and pump.
