  However, in the above-described conventional food heating apparatus, the food is baked by burning the burned material such as soot disposed below, so that the lower half of the food is heated intensively and the upper half is sufficient. There was a problem that it was not heated.

  In order to solve such a problem, it is conceivable that each food is turned upside down and reheated or heated from above using a gas burner or the like. However, in the former method of reversing, it is difficult to surely invert each food, and further, it is necessary to heat again, so that the production efficiency is greatly reduced. Further, the latter method of heating from above with a gas burner overturns the original purpose of burning firewood, pine needles, firewood, chips, etc. and baked richly and is difficult to adopt.

As a result, the entire object can be baked from above and below evenly. At the same time, since smoke stays in the portion of the flame reflecting member, smoke from different directions is applied to the object to be heated, so that the entire object to be heated can be smoked. Since the residence time and the residence distance of smoke become long, it becomes possible to perform more effective soot.

  Of course, the object to be heated is placed on the first conveyance zone and conveyed, and the object to be heated is heated while being burnt on the second conveyance zone. In addition, the heating temperature of the heated product can be kept substantially constant, and the baking condition between foods can be made uniform and the food can be cooked with a rich flavor.

  The flame reflecting member is preferably a member having a plurality of grooves on the reflecting surface. The plurality of grooves include grooves that run parallel to each other in the same direction as the traveling direction of the first transport belt, or grooves that run parallel to each other in a direction oblique or perpendicular to the travel direction of the first transport belt. More preferably. It is also preferable that each of the plurality of grooves is a square cross-section groove or a round cross-section groove.
