These operation switches 41 and 42 and timers 43 and 44 are installed in the main control room 4, and the control device 40 controls the operations of the first and second motors 11 and 21 based on these operations. By controlling, the drive shaft 8 is rotated and reciprocated.

  Next, the operation | movement and usage method are demonstrated in detail about the sweet potato heating apparatus 1 of an above-described structure. First, as shown in FIG. 5, the net member 92 is in an open state in which an opening 95 is formed, and the sweet potato F is accommodated in the accommodating portion 90 from the opening 95. Thereafter, the base member 93a, 93b at one end and the other end of the mesh member 92 are coupled by magnetic adsorption, and the fasteners 94a, 94b are engaged to form the rotating body 9 (FIGS. 1 and FIG. 1). 2).

  When the first operation switch 41 is operated to drive the first motor 11 of the rotary drive device 10, the drive shaft 8 rotates in a fixed direction and the rotating body 9 rotates integrally with the drive shaft 8. . When the rotating body 9 rotates, the sweet potato F rotates in the housing portion 90 by the projection 96 projecting from the inner peripheral surface of the rotating body 9 being caught on the surface. Thereby, since the heat released from the heating means 7 is uniformly applied to the surface of the sweet potato F, the sweet potato F is uniformly heated without unevenness.

  When the sweet potato F is sufficiently heated, the first operation switch 41 is operated to stop the rotation of the drive shaft 8 and the rotating body 9, and the base members 93a and 93b of the net member 92 of the rotating body 9 are separated. Then, the heated sweet potato F is taken out from the opening 95, and a new sweet potato F is stored in the storage unit 90. Then, the new sweet potato F is continuously heated.

By driving the second motor 21, the drive shaft 8 and the rotating body 9 are moved downward as shown in FIG. 7, and the sweet potato F is brought into contact with a large number of pebbles 52 provided in the main body 30.・ Immerse it. Thereby, the sweet potato F is first stone-baked by the pebbles 52 whose lower surface (referred to as “surface 1”, see FIG. 7) is heated by the heating means 7.

  When the surface 1 of the sweet potato F is sufficiently stone-baked, the drive shaft 8 and the rotating body 9 are moved upward by operating the second operation switch 42 to reversely drive the second motor 21. Thus, the longitudinal movement gear 14 of the drive shaft 8 is engaged with the drive gear 13. At this time, the heating time may be set by the second timer 44, and when the second timer 44 is up, the drive shaft 8 and the rotating body 9 may be automatically moved upward. In this state, the first operation switch 41 is operated to drive the first motor 11, and the drive shaft 8 and the rotating body 9 are rotated, so that the sweet potato F rotates in the housing portion 90, and the sweet potato F The face 2 that has not yet been stone-fired (opposite the face 1; see FIG. 7) faces downward.

  Then, after the first operating switch 41 is operated to stop the rotation of the drive shaft 8 and the rotating body 9, the second operating switch 42 is operated to move the driving shaft 8 and the rotating body 9 downward. Thus, the sweet potato F is brought into contact with or buried in the layer of pebbles 52 with its surface 2 facing downward. Thereby, the surface 2 of the sweet potato F is stone-baked by the pebbles 52. The same operation is repeated, and the surface 3 and surface 4 (see FIG. 7) of the sweet potato F are stone-fired in order and the entire surface thereof is uniformly stone-fired, so that the sweet potato F is heated uniformly and evenly. It is baked into the grilled rice cake.

  According to the sweet potato heating device 1 having the above-described configuration, the protrusion 96 is provided on the inner peripheral surface of the rotator 9 to rotate the sweet potato F together with the rotator 9 so that the heat released from the heating means 7 is Since the surface is uniformly applied to the surface, the structure of the sweet potato heating device 1 can be simplified and downsized. Furthermore, it is not necessary to install the heating means 7 at a plurality of locations in the main body, and it is only necessary to install the heating means 7 at one location. Therefore, the sweet potato F is not overheated, and the cooked sweet potato F is less sweet. No problem arises.

  In the present embodiment, two rotating bodies 9 are arranged in parallel in the main body 30, but one rotating body 9 may be used, and three or more rotating bodies 9 are arranged. Is also possible.

  In addition, the layer of the pebbles 52 positioned above the heating means 7 is not necessarily provided, and the sweet potato F is heated by moving the drive shaft 8 and the rotating body 9 in the vertical direction as needed during the heating of the sweet potato F. Heating strength to cook sweet potato F deliciously, such as by heating close to the means 7 and heating the surface strongly, such as by baking the sweet potato F away from the heating means 7 You may make it selectable.
