Abstract:
A method of separating biologically ingestible microparticles is used to obtain biologically ingestible microparticles in a thin film fluid formed between two processing formed by a fluid to be processed containing at least a first solvent in which an objective substance to be pulverized is dissolved and a second solvent in which the solubility of the microparticles is lower than in the first solvent. The biologically ingestible microparticles are separated by a neutralization reaction in the thin film fluid.
