Abstract

A crystallization apparatus with a closed cylindrical tank has radial dividing walls in the lower tank portion to define therebetween a plurality of compartments ranging from a first compartment upstream to an output compartment downstream. All the walls, except the one between the output compartment and the first compartment upstream thereof, have ports permitting communication between the compartments for continuous flow therethrough of a solution whose solute is to be crystallized by evaporation. A feeding means for feeding an undersaturated solution of the solute into successive compartments is arranged in the upper portion of the tank for rotation about the vertical tank axis to sweep over the successive compartments, and shutters are provided for controlling the amount of the undersaturated solution fed to each of the compartments.
