As a result, the sprinkled food h clogged in the spray hole s of the intermediate slide plate 74 is forcibly shaken downward from the spray hole s of the lower fixed plate 72. Further, in the reversing step H, the driving source 75 is driven in a timing with the operation of the conveyor 83, and the three reversing plates 84 on the front end side of the rotating shaft are intermittently rotated 180 degrees in accordance with this timing operation. The rice ball W fitted and held in the fitting portion 84a of the reversing plate 84 is reversed from one surface to the other surface.

  In the automatic packaging process J, the rice ball W is lifted and moved by the lift mechanism 52 of the automatic packaging mechanism 51, and the packaging turntable is rotated intermittently after being automatically wrapped while being folded from above with a sheet member Q containing nori. It is pushed out to the 53 side by the transport block 60 and supplied to the inside of the rice ball insertion hole R. That is, the rice ball W on the mounting table 57 is supplied into the insertion portion 59A of the insertion block 59 in a state where the seaweed-containing sheet member Q supplied and arranged by the conveyor 64 is wound, and pressed by the pressing member 59B. Then, with the shape retaining rod member 58 locked, only the mounting table 57 is raised to the position of the transport block 60 and is placed in the vicinity of the packaging turntable 53. Then, the conveyance block 60 is slid forward, and the rice ball W in the insertion block 59 is conveyed to the rice ball insertion hole R side of the packaging turntable 53 in a state in which the sheet member Q with seaweed is wound around the lower surface of the rice ball W. Let

  Finally, in the sealing step K, the overlapped portion of the sheet member Q with seaweed after packaging is fixed by thermocompression bonding using the heat press device 103 of the seal portion 61. That is, the corners of the seaweed-containing sheet member Q in a state in which the rice ball W conveyed into the rice ball insertion hole R is rolled up and a part of the rice ball is protruded upward, are folded inward by the folding baffle plate 101 and the folding lever piece 102. After folding, it is fixed by crimping with the heating rod of the heat press apparatus 103.
