Abstract
The invention addresses the problem of providing a method for producing microparticles. Provided is a method for producing microparticles. For the first process, seed microparticles are separated in a thin film fluid that forms between at least two processing surfaces, which are disposed facing each other, which can approach or separate from each other and at least one of which rotates relative to the other, and the fluid comprising the separated seed microparticles is discharged as a discharge fluid. Subsequently, for the second process, the separated seed microparticles are grown in the discharged discharge fluid to obtain the intended microparticles. Uniform and homogeneous micropartcles are obtained as a result of the microparticle producing method comprising the two process.

A method for producing a microparticle wherein the method comprises at least two steps as following:
- (I) a first step of separating a seed microparticle in a thin film fluid formed between at least two processing surfaces which are disposed in a position they are faced with each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, whereby discharging a fluid which contains the seed microparticle thus separated as a discharge fluid, and
- (II) a second step of growing the separated seed microparticle in the discharge fluid whereby obtaining a prescribed microparticle.
A method for producing a microparticle wherein
- the method is to mix a raw material fluid in which at least one substance to be separated is dissolved or molecular dispersed in a solvent with a separating fluid to separate the substance to be separated, whereby separating the substance to be separated,
- the method comprises at least two steps as following:
- (I) a first step in which the raw material fluid is mixed with the separating fluid in a thin film fluid formed between at least two processing surfaces which are disposed in a position they are faced with each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, whereby separating a seed microparticle of the substance to be separated and discharging a fluid which contains the seed microparticle thus separated as a discharge fluid, and
- (II) a second step of growing the separated seed microparticle in the discharge fluid whereby obtaining a prescribed microparticle.
