PROBLEM TO BE SOLVED: To provide a rice ball making device with which a rice ball having steady outside and airy inside like those of a hand-made one is easily formed, which does not cause damage such as kneading of rice on the rice ball, and which easily and reliably forms a filling hole.SOLUTION: The device works through: a process (A) of supplying boiled rice P in a supply mechanism 25 a process B of fraying the boiled rice P in a fray mechanism 25a and a process C of dividing the boiled rice P in a dividing mechanism 24. In the device, one divided side in the dividing process C includes: a main measuring process D of using a main measuring part 11 measuring part of the target value of the weight of the boiled rice P a pre-forming process E of using the pre-forming part 12 of the measured boiled rice P and an ingredient supply process F in an ingredient supply mechanism 15 after the pre-forming process E. Another divided side in the dividing process C includes an auxiliary measuring process G with an auxiliary measurement part 13 measuring the remaining amount of the weight of the boiled rice P, and an ingredient-enclosing/forming process H of enclosing the boiled rice P measured in the auxiliary measuring process G with the boiled rice P obtained after the ingredient supply process F to block the filling hole.COPYRIGHT: (C)2010,JPO&INPIT【課題】手作りのように外側がしっかりとして内部がふんわりとしたおにぎりが容易に成形でき、シャリを練る等の障害がなく、容易且つ確実に具穴を形成できるようにする。【解決手段】供給機構25によるシャリPの供給工程Aと、解し機構25aによるシャリPの解し工程Bと、分岐機構24によるシャリPの分岐工程Cとを備え、分岐工程Cによる一方の分岐側は、シャリP重量の目標値の一部を計量する主計量部11による主計量工程Dと、主計量後のシャリPの予備成形部12による予備成形工程Eと、予備成形工程E後の具材供給機構15による具材供給工程Fとを有し、分岐工程Cによる他方の分岐側は、シャリP重量の目標値の残量を計量する補助計量部13による補助計量工程Gと、補助計量工程Gで計量したシャリPを具材供給工程F後のシャリPに包餡して具材供給後の具穴を塞ぐ包餡・成形工程Hとを有する。【選択図】図7
