Abstract
Crystalline &agr;-lactose monohydrate is recovered from a viscous lactose-containing aqueous liquid by subjecting said liquid to simultaneous heating, removal of evaporated vapor and mechanical agitation at high shear rate to provide a crystallization promoting decrease of the viscosity of the liquid with crystals formed and suspended therein to progressively concentrate the agitated liquid and simultaneously crystallize lactose therefrom. Subsequent cooling, drying, and disintegration yield particulate &agr;-lactose monohydrate.
