  The following forming apparatuses are known as one form of such cooked rice forming apparatuses. That is, the strip-shaped cooked rice previously shaped to a predetermined width by the feeding means for feeding the cooked rice is fed in the vertical direction, and the strip-shaped cooked rice is molded into a predetermined shape by the molding means disposed below the feeding means It is.

  In particular, the molding means is configured by arranging a left side molded body and a right side molded body of a pentagonal prism on each of the left and right sides of a strip-shaped cooked rice, and the left and right side molded bodies are rotated while rotating the left and right side molded bodies. A band-shaped cooked rice is sandwiched between the surfaces to form, for example, nigiri sushi balls (see, for example, Patent Document 1).

That is, in this molding mechanism, the mold holes are respectively provided in the five peripheral surfaces of the pentagonal prism body in the left molded body and the right molded body, and the mold holes of the left molded body and the right molded body are respectively provided. While the cooked rice is being fed, the peripheral surface of the left molded body and the peripheral surface of the right molded body are overlapped to press the cooked rice from the left and right directions, so that the left molded body and the right molded body have the mold holes. A ball is formed.

A cooked rice receiving surface for receiving the dropped sheet-shaped cooked rice R is formed.

  At this time, the left support mold 22a and the right support mold 23a form an insertion hole 27 in the left pressing mold 22b and the right pressing mold 23b, and the central mold support 26 is formed in the insertion hole 27. Let it be in the inserted state.

  Such a state of the left supporting mold 22a, the right supporting mold 23a, the left pressing mold 22b, and the right pressing mold 23b is referred to as an initial position. In FIG. 5, G is an ingredient placed on the sheet-like cooked rice R. The ingredient G is desirably placed in an area supported by the central mold 21 of the sheet-like cooked rice R.

  Next, in the molding unit 20 in which the sheet-shaped cooked rice R is dropped from the supply unit 10 and received by the rice receiving surface, the center molding mold 21 is inserted through the insertion hole 27 formed by the left support mold 22a and the right support mold 23a. FIG. 6 shows the edges of the sheet-shaped cooked rice R supported by the left pressing mold 22b and the right pressing mold 23b by lowering to a part and rotating the left pressing mold 22b and the right pressing mold 23b, respectively. As shown, it is folded over the central mold 21.

  In addition, by winding the sheet-shaped cooked rice R around the ingredients G, the ingredients G are cooked while exposing a part of the ingredients G having a relatively large size from the cooked rice, such as shrimp fries such as tempura. And can be applied to various ingredients G.

  Furthermore, by using the sheet-shaped cooked rice R in the supply unit 10, the cooked rice can not only reliably cover the ingredients G with the sheet-shaped cooked rice R, but also the rice balls T without causing density variation in the cooked rice. Therefore, the rice ball T having a high texture and improved handmade feeling can be produced.

  Further, after the rice ball T is formed, the left pressing mold 22b and the right pressing mold 23b are not reversely rotated, but the left pressing mold 22b and the right pressing mold 23b are replaced with the left supporting mold 22a and the right supporting mold. By rotating together with 23a in the rotation direction and returning to the initial state, the control mechanism of the left molding mold 22 and the right molding mold 23 can be simplified, and a compact food molding apparatus can be obtained.

  Moreover, it is possible to smoothly remove the mold from the left-hand support mold 22a, the right-hand support mold 23a, the left-pressing mold 22b, and the right-pressing mold 23b from the formed rice ball T. It is possible to prevent the rice ball T from falling.
