PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a rice ball, capable of manufacturing a rice ball with a rice density as low as possible while surely retaining the rice ball shape after molding, allowing a pressing region on the surface to be evenly displaced without increase in the rice density at a specific spot to be pressed for shaping on the surface of the rice mass, with a reliable shaping operation along the entire surface using a light pressing force, requiring no highly compressive shaping.SOLUTION: A pressing region on the surface of a rice mass molded into a specific shape is pressed for shaping. The pressing region is displaced more than once during shaping by pressing.COPYRIGHT: (C)2016,JPO&INPIT【課題】成形後のおにぎり形状を確実に保形しながら米飯密度を可及的に低くなるようにしたおにぎりを製造可能であり、しかも、米飯塊の表面を所定箇所でのみ押圧整形して米飯の密度を高くすることもなく、満遍なく表面の押圧部位を変位させることができ、高圧迫の整形を要することなく軽い押圧力で全表面に沿った確実な整形作業を達することができるおにぎり製造装置を提供する。【解決手段】所定形状に成形した米飯塊の表面の押圧部位を押圧しながら整形すると共に、押圧部位は押圧整形時に複数回変位すべく構成した。【選択図】図2
