CRYSTALLIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/013540
Kind Code:
A1
Abstract:
[Problem] To provide a crystallization device with a simple structure and high classification performance in crystallization. [Solution] The central upper section inside a vertical container (2) having a classification limb (3) at the bottom (2b) is provided with a rotor blade means (5) for generating a swirling flow of a turbid starting material slurry inside the container (2) along the inner circumferential surface of the container (2), and a fluid flow direction-changing means (6) for causing the starting material fluid to flow upward in the central section of the container (2) is provided in the central section of the bottom surface of the container. The fluid flow direction-changing means (6) is obtained from band-shaped plate baffles (6a) provided in a radial pattern on the bottom surface.
