Abstract:
A crystallization apparatus for the crystallization of solids from their solutions, comprising an upper part (2) and a lower part (1)having a heatable and coolable stirred vessel (1) with an agitator (6), optionally a feed line (12) for the crystallization solution and optionally a discharge line (14) for the suspension of the crystallized product, as the lower part and a conical, heatable and coolable sedimentation section (2) having a stirring element (9, 10) running around the wall, optionally a discharge line (13) for the solution depleted in product and an opening (18) to the stirred vessel (1), as the upper partwherein the agitator (6) generates, in the region of the opening (18), a flow of the crystallization solution directed away from the opening (18).
