Beschreibung
Zusammenfassung:	The present invention enhances productivity in separating a microcapsule from an aqueous dispersion and reduces labor required for ensuring safety. A method for producing a microcapsule powder comprises a concentration step. In the concentration step, an aqueous dispersion of a microcapsule is supplied into a cyclone 10, and the aqueous dispersion is then concentrated. The concentration step comprises an aqueous dispersion-supplying step S100 and a concentrated dispersion-recovering step S102. In the aqueous dispersion-supplying step S100, the aqueous dispersion is supplied into a cylindrical member inlet. In the concentrated dispersion-recovering step S102, a microcapsule dispersion is recovered. The microcapsule dispersion is discharged through a conical member outlet.
