Abstract: A granulating method is a method in which powder containing a water-soluble component is granulated. In the disclosed granulating method, a dispersion element, wherein fine water droplets are dispersed in superheated steam, is expelled from a nozzle, and thus the dispersion element and powder in a flowing state come into contact with one another. It is preferable that the mass ratio of superheated steam contained in the dispersion element, as a mass ratio found from the theoretical flow amount of superheated steam expelled from the nozzle, and the actual flow amount of water supplied to the nozzle, be set in a range of 20-70 mass %.
