Thus, as shown in FIG. 9, the divided plate 4c of the upper forming plate 4 ′ is brought into contact with the connecting region 7c portion of the lower forming plate 7, and the cooked rice a inside the rice ball forming hole 8 is divided into two, One cooked rice a can be formed into a rice ball shape by narrowly pressing the first upper forming plate 4a and the first lower forming plate 7a, and the other cooked rice a can be formed into the second upper forming plate 4b and the second lower plate. It can be formed in a rice ball shape by narrowing pressure with the forming plate 7b. In addition, the rice storage a can be pressed by the material storage hole forming projection 20 to form a recess for storing the material in the center of the upper surface of the rice ball.

  In particular, in this embodiment, since the amount of lowering of the operation lever 5 is regulated by the stopper 28, the cooked rice a accommodated in the forming frame 1 can always be pressed with a constant pressing force, and skill is required. The rice balls b that are press-molded at a constant pressure can be formed.

  After the rice ball b is formed from the cooked rice a as described above, the upper forming plate 4 ′ is removed from the rice ball formation hole 8 by raising the operation lever 5. As described above, in the present embodiment, the upper forming plate 4 ′ can be easily inserted into and removed from the forming frame 1 by the operation lever 5, and the rice balls can be efficiently formed.

  Next, the forming frame body 1 is removed from the support base 2 and moved to the rice ball extraction region 30, and the lower surface of the lower forming plate 7 is brought into contact with the push-up operation body 29 in the rice ball extraction region 30 as shown in FIG. Thus, the lower forming plate 7 is moved upward relative to the forming frame 1 to push down the forming frame 1. By this operation, as shown in FIG. 11, the rice ball b can be pushed out of the rice ball formation hole 8. In particular, since the rice balls b can be taken out without removing the lower forming plate 7 from the inside of the forming frame 1, workability when continuously forming the rice balls b can be improved. Further, the formed frame 1 that has been pushed down can be held by the horizontal piece of the rice ball take-out frame 6.
