Title
(EN) Crystallization Apparatus and Crystallization Method
Abstract
(EN)

Provided is a technique for continuously performing poor solvent crystallization or reactive crystallization. A porous membrane in which multiple pores through which a liquid passes are formed internally partitions the treatment container into a first flow space and a second flow space. A raw material liquid supply unit continuously supplies a raw material liquid to the first flow space. A treatment liquid supply unit continuously supplies a treatment liquid to the second flow space at a pressure at which the treatment liquid passes through the porous membrane and enters the first flow space. An extraction unit continuously extracts a mixed liquid of the raw material liquid and the treatment liquid from the first flow space. An aging unit precipitates and grows crystals of a target substance from a mixed liquid.
