Title:
CRYSTALLIZER AND CRYSTALLIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/239550
Kind Code:
A1
Abstract:
[Problem] To provide a technique for continuously performing a poor solvent crystallization or a reactive crystallization. [Solution] According to the present invention, a porous film 21 in which a number of pores allowing a liquid to pass therethrough are formed to partition a treatment container 2 into a first circulation space 201 and a second circulation space 202. A raw material liquid supply part 11 continuously supplies a raw material liquid to the first circulation space 201, and a treatment liquid supply part 12 continuously supplies a treatment liquid to the second circulation space 202 at a pressure under which the treatment liquid passes through the porous film 21 and enters the first circulation space 201. An extraction part 23 continuously extracts a liquid mixture of the raw material liquid and the treatment liquid from the first circulation space 201, and an aging part 3 deposits and grows the crystal of a target substance from the liquid mixture.
