[Industrial applications]

 The present invention relates to an apparatus for inverting food dough such as dorayaki and pancake. More specifically, the food dough having one side baked in the baking process of the food dough is turned upside down to backfire the food dough. It relates to a food dough reversing device.

[0002]

[Prior art]

 As a device for reversing food dough, those shown in FIGS. 10 and 11 are already known. In this reversing device, a horizontal rotating shaft 105 is fed to the conveyor 103 above a copper conveyor 103 which feeds the food dough 101 while heating the food dough 101 by a heating means 102 such as a gas burner. The scraper 107 is provided on the rotary shaft 105 so as to project forward, and the rotary shaft 105 is rotated when the food dough 101 rides on the scraper 107 from the conveyor 103. By doing so, the scraper 107 is rotated backward, and the food dough 101 on the scraper 107 is thrown backward so that the food dough 101 is turned upside down.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional food dough reversing device has the following problems. (1) The scraper 107 is provided on the rotary shaft 105 so as to project forward, and the scraper 107 is rotated about the rotary shaft 105 so that the food dough 101 on the scraper 107 is turned upside down. In other words, the food dough is dropped together with the scraper 107 over the rotary shaft 105 and behind the rotary shaft 105, so that the food dough is thrown down from a high position. As a result, the food material is damaged and the texture is reduced. (2) Since the food material is thrown down from a high position, the material will be scattered when the surface of the food material is not dry. (3) In order to avoid the problem of (2) above, it is necessary to dry the food dough by overheating before inversion. However, when the food dough is dried by heating over heat, the food dough becomes too dry and dry, and the texture deteriorates. (4) In the case of Dorayaki, if the top heat is used, it becomes different from the original Dorayaki, that is, the original Dorayaki. (5) In the case of dorayaki, when top heat is used, the upper part 101a of the food dough 101 is heated by the top heat and swells as shown in FIG. Therefore, when the food dough 101 is turned upside down, the area of the portion (upper portion 1a) of the food dough 101 that contacts the conveyor 103 becomes smaller. As a result, the baked area of the surface of the food dough (upper part 101a) is reduced, and both the appearance and texture of dorayaki are impaired. The present invention has been made in order to solve the above-mentioned problems in the conventional food dough inverting device.
