[challenge] it without having to dirty your hands and clothes, and Ya rice balls that form a more three-dimensional three-dimensional shape to provide a large number moldable rice ball shaper and ingredients shaper at once ingredients. A rice ball forming apparatus 1 includes a plurality of through-holes 21 and mold 2 which are spaced to each other arranged, and a number and dimension corresponding to the through hole 21 and the through hole 21 It includes the extruding member 3 provided with a plurality of extrusion portions 31 insertable in multiple can be inserted and a number and dimension corresponding to the through hole 21 and the through hole 21 and the shape forming unit 4. Through-hole 21 of the mold 2 to accommodate the rice. Shaped molded part 4, confers rice three dimensional rice ball shape is accommodated in the through hole 21 by insert-pressed from the upper side of the mold 2 the shape forming unit 4 to the through hole 21. Extruding member 3, by disposing, inserted from the lower side of the mold 2 the extrusion unit 31 to the through hole 21, the precast multiple rice balls can overcall the mold 2 the top surface at a time.BACKGROUND 1【課題】手や衣服を汚す事無く、より三次元的な立体形状を成すおにぎりや食材を一度に多数成形可能なおにぎり成形器や食材成形器を提供する。【解決手段】おにぎり成形器1は、複数の貫通孔21が互いに離間して配列された型枠2と、貫通孔21に対応した寸法と数とを有しかつ該貫通孔21に挿入可能な複数の押し出し部31が設けられた押し出し部材3と、貫通孔21に対応した寸法と数とを有しかつ該貫通孔21に挿入可能な複数の形状成形部4とを備える。型枠2の貫通孔21はご飯を収容する。形状成形部4は、型枠2の上側から形状成形部4を貫通孔21へ挿入・押圧することで貫通孔21に収容されたご飯に三次元的なおにぎり形状を付与する。押し出し部材3は、型枠2の下側から押し出し部31を貫通孔21へ配置・挿入することで、成形済みの複数のおにぎりを一度に型枠2上面へせり上げることができる。【選択図】図1
