  The folding mold with such a small and simple configuration and good operability does not lose the shape of the surface and can easily reproduce the fluffy feeling and texture that are similar to those of a sharp ball when grasped by hand. In addition, since the entire folding mold after folding is a small and simple structure that forms a slab-shaped casing, that is, a rectangular parallelepiped casing, the folding operation is easy and is not bulky during conveyance.

  Further, in the present invention, after the folding mold is folded, the sealed and shaped rice-forming space surrounded by the bottom mold, the one-side recessed mold, and the other-side recessed mold has a constant internal space volume. Depending on the measurement of the sheet-like cooked rice (for example, change of sheet thickness, etc.), the rice balls themselves can be set to have a desired hardness that does not impair the texture.

  In addition, when the folding mold is folded, the long cylindrical rice-forming space surrounded by the bottom mold, the one-side concave mold, and the other-side concave mold has a groove hole that opens upward. Even if there is an excess amount due to some error in the measurement of the supplied sheet-shaped cooked rice (for example, due to changes in sheet thickness, etc.), the sheet-shaped cooked rice by folding the one side concave mold and the other concave mold At the time of forming the peripheral side surface, the excess amount of the cooked rice escapes upward along the groove, so that the texture is not impaired by inserting and pressing the upper mold for upper molding into the groove thereafter. It can be set to be a hard ball.

  Furthermore, since it includes a rice cracking step for performing a rusting operation on the sheet-shaped cooked rice after the rice-feeding step, the sheet-shaped cooked rice can be reliably folded with a uniform thickness when folding the folding mold. .
