You may make it have a control means which controls discharge | emission amount and adjusts the outer peripheral surface temperature of the said heating rotating drum.

  As described above, the processed food manufacturing apparatus of the present invention forms the introduction path for introducing the thermal fluid into the heating rotary drum in the shaft body that rotates the heating rotary drum, and the thermal fluid in the heating rotary drum or a change thereof. Since a discharge path for discharging the material is formed and heat transfer means for transferring heat from the thermal fluid to the outside in the radial direction is arranged in the heating rotary drum, the rotary drum can be configured with a simple configuration. There is an effect that the processed food can be stably manufactured by keeping the outer peripheral surface temperature distribution uniform and maintaining the outer peripheral surface temperature of the rotating drum constant.

  In the present invention, the outer surface temperature of the heated rotating drum is adjusted by controlling the discharge amount of the thermal fluid or the change material, so that the outer surface temperature of the heated rotating drum can be easily adjusted.

  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

  Referring also to FIG. 2, a hollow shaft body 19 extends in parallel to the upper surface of the housing 11, and a steam inlet passage which will be described later is formed on the shaft body 19 and a drain water delivery passage is provided. Is formed. The shaft body 19 is rotatably supported by the first and second bearing bodies 20a and 20b attached to the support base 20 disposed on the upper surface of the housing 11, and one end of the shaft body 19 (the left end in FIG. 2). ) Is connected to the central portion of the cylindrical heating rotary drum 21, and the heating rotary drum 21 rotates around the shaft body 19 by the rotation of the shaft body 19.

  The other end (right end in FIG. 2) of the shaft body 19 is coupled to a supply / discharge pipe 23 by a rotary joint (rotary coupling portion) 22 and, as will be described later, high-pressure steam from the supply / discharge pipe 23 to the steam inlet path. (Thermal fluid) is supplied, high-pressure steam is fed into the heating rotary drum 21 from the steam feed passage, and drain water (changed matter) is discharged from the supply / discharge pipe 23 through the drain water feed passage. The As shown in FIG. 2, a steam supply port (steam supply) and a drain water discharge port (drain discharge) are formed in the supply / discharge pipe 23, and a drain water discharge device 24 is disposed on the drain water discharge side. As will be described later, the drain water accumulated in the heating rotary drum 21 is discharged by the drain water discharge device.

  As a result, when the drive motor 25 is driven, the gear 27 rotates through the gear 26, and the shaft body 19 rotates. That is, the heating rotary drum 21 rotates. At this time, since the supply / discharge pipe 23 is connected to the shaft body 19 via the rotary joint 22, the supply / discharge pipe 23 does not rotate.

  FIG. 3 is a diagram showing a side cross-section of the processed food manufacturing apparatus. As shown in the figure, a plurality of inner parts of the heating rotary drum 21 are concentrically with the outer peripheral surface of the heating rotary drum 21 at predetermined intervals in the radial direction. The partition wall heat transfer members (ring-shaped members) 28 are arranged, and these partition wall heat transfer members 28 are supported by support members 29 that extend radially from the vicinity of the center of the heating rotary drum 21 (FIG. 4). See also).

  Although not shown, each partition heat transfer member 28 and support member 29 are formed with a plurality of passage passage holes through which high-pressure steam passes, and the high-pressure steam supplied near the center of the heating rotary drum 21 passes through the passage passage. It will diffuse through to the outside in the radial direction. The partition heat transfer member is heated by contact with the high-pressure steam, and heat is transferred to the outer peripheral surface of the heating rotary drum 21 and the heat is accumulated.

  Referring again to FIG. 1, the heating rotary drum 21 rotates in the direction indicated by the solid arrow in FIG. 1, but a scraper (peeling member) 30 is disposed downstream of the rotation direction, A conveyor 31 is arranged on the side. When manufacturing thin-skinned processed foods such as spring rolls, the dough is pressure-fed from the dough liquid hopper 14 to the nozzle 17, and the dough having a predetermined thickness is continuously provided on the outer peripheral surface of the heating rotary drum 21 from the nozzle 17. Supplied. In addition, slits with a predetermined interval are formed in the nozzle 17, and a cloth having a predetermined thickness is supplied from the slits.

The outer surface temperature of the rotating drum 21 can be kept uniform. That is, the drain water discharge device 24 controls the discharge amount of the drain water, and the outer peripheral surface temperature of the heating rotary drum 21 is adjusted.

  Furthermore, as described above, the partition heat transfer member 28 transfers heat to the outer peripheral surface of the heating rotary drum 21 and accumulates heat, so that the heating rotary drum 21 can be easily heated. That is, the heating rotary drum 21 can be controlled by heating with a reduced amount of water vapor.

  In the above-described first embodiment, the heating rotary drum 21 is heated using high-pressure steam, but pressurized hot water or heat transfer oil may be used as the thermal fluid instead of the high-pressure steam. When the pressurized hot water is used, the steam supply path 23a and the steam inlet path 18b described above become the hot water supply path and the hot water inlet path, respectively, and the drain water delivery path 18a and the drain water discharge path 23b are respectively the hot water delivery path. And a hot water discharge channel. Further, the drain water discharge device 24 is a hot water discharge device. Then, the hot water discharge amount is adjusted by the hot water discharge device, and the heating rotary drum 21 is heated.

  Similarly, when heat medium oil is used, the steam supply path 23a and the steam inlet path 18b described above become the heat medium oil supply path and the heat medium oil inlet path, respectively, and the drain water discharge device 24 is the heat medium oil. It becomes a discharge device. The drain water delivery path 18a and the drain water discharge path 23b serve as a heat medium oil delivery path and a heat medium oil discharge path, respectively. Further, the heating medium drum discharge amount is adjusted by the heating medium oil discharging device, and the heating rotary drum 21 is heated. In any case, various heating media can be used.

  A heating rotary drum is formed by forming an introduction path for introducing the thermal fluid into the heating rotary drum and a discharge path for discharging the thermal fluid in the heating rotary drum or a variation thereof in the shaft rotating the heating rotary drum. A heat transfer means for transferring heat from the heat fluid to the outside in the radial direction is arranged in the inside so that the heating rotary drum is heated by the heat fluid, so that it is easy to manufacture thin processed foods Temperature control can be applied to an apparatus for producing a thin processed food.
