Has been.
Further, the filling device supply apparatus is arranged so that the supply port faces downward, and is configured by a tapered hopper portion and a quantitative supply cylindrical portion, and has a filling member extrusion screw member therein. .
Furthermore, the cutting mechanism is provided with a cutting blade that is substantially S-shaped and that forms a blade portion at its vertically curved bulge.

  The rolled sushi obtained by the above configuration is a rice roll that is plump and has a stable supply of ingredients, and the cut surface of the rolled sushi is the same as when cut with a kitchen knife. It was what was.

  However, the manufacturing apparatuses of Patent Documents 1 and 2 each have only one sushi rice molding pattern, and if you want to manufacture both bowl-shaped shawl and rolled sushi, you must introduce two apparatuses. In addition, the equipment cost increases, and a certain amount of installation space is required.
