PROBLEM TO BE SOLVED: To provide a rice powder manufacturing apparatus more compact than a conventional powder manufacturing apparatus and equal to a conventional pulverizer in pulverization ability.SOLUTION: A rice powder manufacturing apparatus comprises a cylindrical housing having a peak/valley surface on the inner surface and a plurality of rotors fixed on a rotary shaft in the housing, where the rotor is radially provided with a plurality of upright blades, the housing top with a fan, the housing bottom with an air introduction port, and the housing top with an exhaust port, so that a raw material cast from the air introduction port is guided into the housing by swirl air streams the fan raises. The raw material introduced to the housing repeatedly goes through introduction into a space between the rotor and a rotor above the same through a gap between the outer peripheral surface of the rotor and a plurality of crests, collection in the outer periphery direction by being given centrifugal force with the blades, and introduction into the top space through a gap between the outer peripheral surface of the rotor and the crests of the housing inner face, and finally pulverized grains are discharged from the exhaust port.SELECTED DRAWING: Figure 1 |
