Title:
CONTINUOUS CRYSTALLIZER
Document Type and Number:
Japanese Patent JP2011083768
Kind Code:
A
Abstract:
To provide a continuous crystallizer which achieves crystallization having an excellent specific crystal form.
In a first reactor which includes a first inner cylinder rotating by forming a first interspace with the inside wall of a first outer tube, a reaction mixture is allowed to pass through as a spiral flow in the first interspace in a Taylor vortex state to cause blending of the reaction mixture and to cause nucleation. Further, in a second reactor which include a second inner cylinder rotating by forming a second interspace with the inside wall of a second outer tube, the reaction mixture extracted from the first reactor is blended in the second interspace, so that crystals are grown therein.
