PROBLEM TO BE SOLVED: To provide a method for producing particles, in the method of producing particles by an injection granulation method, capable of preventing the coalescence of droplets each other after spraying and stably achieving a narrower grain size distribution.SOLUTION: The method for producing grains comprises: a droplet discharge step of discharging a grain component liquid from at least one discharge hole and making the same into droplets; and a solidification step of solidifying the droplets, where a nozzle for droplet formation and an opening for an air flow addition are formed into the nozzle plate of a droplet discharging means used for the droplet discharge step. |
