Embodiment Construction

[0036] figure 1 The crystallization apparatus 1 provided with the fluid mixing unit 3 which concerns on 1st Embodiment of this invention is shown, This crystallization apparatus 1 is comprised so that a poor solvent (poor solvent, poor solvent) crystallization may be continuously performed. The crystallization device 1 is equipped with: a raw material liquid supply part 11; a poor solvent supply part 21; a fluid mixing unit 3, which mixes a raw material liquid and a poor solvent to generate a mixed liquid (mixed fluid); an aging tube 5, which makes the crystallization of the target substance Precipitation / growth from the mixed liquid flowing out from the fluid mixing unit 3; solid-liquid separation part 50, which separates the crystals grown in the aging tube 5; exhaust part, which captures and removes the mixed liquid towards the aging tube 5 bubbles. In addition, the crystallization apparatus 1 is configured as a downward flow type device in which the raw material liquid a...

Abstract

To generate a mixed fluid by reliably mixing a plurality of fluids flowing in a circulation space and to perform mixing so that the concentration of one fluid in another fluid gradually increases. Provided is a fluid mixing unit comprising: a container to which first fluid and second fluid are supplied, respectively; a cylinder that comprises a porous body to divide the inside of a container intoa first circulation space and a second circulation space enclosing the first circulation space; a first supply opening that supplies a first fluid to one circulation space of the first circulation space and the second circulation space; a second supply opening that is provided on one end side of the container in the axial direction of the cylinder in order to supply a second fluid to the other circulation space; a fluid outlet that is provided on the other end side of the container so as to open only to the other circulation space; and occlusion members that are provided at multiple steps along the axial direction in the other circulation space so as to block the left and right alternately in the other circulation space as viewed in the axial direction in order to form a meandering flow inthe other circulation space and thereby generate a mixed fluid.

Description

technical field [0001] The present invention relates to a fluid mixing unit and a fluid mixing method for mixing multiple fluids in a container to generate a mixed fluid. Background technique [0002] In manufacturing processes such as pharmaceuticals, processing of mixing various liquids is performed. As an example of this mixing treatment, crystallization to obtain crystals of a target substance from a raw material liquid is mentioned. For example, poor-solvent crystallization involves mixing a poor solvent that reduces the solubility of the target substance with a raw material solution in which the target substance is dissolved, and depositing crystals of the target substance in the obtained mixed solution. In addition, the reaction crystallization is to precipitate the crystals of the target substance by mixing the raw material solution containing the raw material substance and reacting with the raw material substance to generate a reaction solution of the target substa...
