A fluid mixing unit includes a cylindrical porous body partitioning a container into a first flow space and a second flow space surrounding the first flow space. A first supply port supplies a first fluid to one of the first and second flow spaces. A second supply port provided on one end side of the container in an axial direction of the cylindrical body supplies a second fluid to the other flow space. An outlet for a mixed fluid is provided on the other end side of the container to be open only to the other flow space. Closing members are provided in a plurality of stages along the axial direction to alternately close a right and a left of the other flow space as seen in the axial direction in the other flow space. A meandering flow is formed in the other flow space to create the mixed fluid.

A calculation device () includes a calculation unit () that: acquires culture data over time indicating a relationship between a DO value detected in a culture solution and an oxygen supply amount controlled by a freely-selected control method, the culture solution being stored in a first culture tank () in which a culturing target material is cultured; identifies a culture model indicating a relationship between the oxygen supply amount for the culturing target material increasing over time and the DO value, based on the culture data; and executes simulation of virtually culturing the culturing target material in a second culture tank () using a culture control method of culturing the culturing target material based on the culture model and the oxygen supply amount in the second culture tank, and calculates parameters to be used in the culture control method based on the simulation result.

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.

Crystallization apparatus and crystallization method

A reciprocating stirrer device with which favorable gas absorption into the stirred substance can be obtained. The reciprocating stirrer device is obtained from: a stirring vessel in which the substance to be stirred is placed; a reciprocating drive shaft provided inside the stirring vessel; a stirring blade connected and affixed so as to intersect the drive shaft; and a microbubble-generating unit. The microbubble-generating unit is obtained from a sparger that is made of a porous body and a gas supply means for supplying a gas to the sparger. Bubbles are generated in the substance being stirred by passing gas supplied to the sparger by the gas supply means through pores of the porous body.
