[0003] As a method of manufacturing a bamboo ring, a paste-like ground fish meat is attached to the outer periphery of a rod-shaped member (skewer) so as to surround a rod-shaped member (skewer) having a circular cross section, and then formed into a cylindrical shape.
The rod-shaped member is exposed to a high-temperature atmosphere (generally, an atmosphere led from a baking furnace described later) and heated from the outer surface to give the fish meat surimi to sit. Then, the rod-shaped member is inserted into a baking furnace (heating furnace). Usually, the surimi is heated and baked by heat transfer or radiant heat from the outer surface side, sterilized, and then taken out of the furnace and the heated food (bamboo ring) is extracted from the rod-shaped member.

[0005] In the method of heating the fish meat surimi from the outer surface to give a sitting position as described above, it is difficult to uniformly raise the temperature to the inside, so that the temperature rise inside the surimi is delayed and the whole surimi is given a sitting position. It takes a long time to sufficiently gel the inside, and there is a problem that the equipment must be enlarged.

[0006] On the other hand, among fish meat kneaded products, kamaboko and the like have recently been formed by shaping a raw fish meat body into a predetermined shape, passing current between the electrodes, and causing self-heating by the electric resistance of the surimi body. Has been developed and put into practical use. According to such a heating method, since heat is generated from the inside of the fish meat surimi, the temperature of the whole surimi can be uniformly and quickly increased from the inside.

[0007] The bamboo ring, which is a hollow kneaded product,
After the fish meat is formed into a cylindrical shape on the outer peripheral surface of the metal rod-shaped member, a voltage is applied between the metal rod-shaped member and the electrode while rolling the formed body together with the rod-shaped member on the smooth electrode surface. In addition, it has been attempted to apply a current to a portion of the cylindrical surimi molded body interposed between the rod-shaped member and the electrode to generate heat by the electric resistance of the surimi. If the electric resistance heating is used to heat the fish meat surimi in the production of bamboo rings, the surimi can be uniformly heated from the inside as described above, so that the heating time is shortened, and the equipment is accordingly installed. It is considered that the size and size of the device can be reduced and the productivity can be improved.

In the conventional method for manufacturing bamboo rings, a step of forming a fish meat surimi into a cylindrical shape on the outer periphery of a rod-shaped member and a step of subsequently heating for sitting or baking are separate. Even when utilizing electric resistance heating to heat the surimi, it is only necessary to apply the electric current again after attaching and forming the surimi in a cylindrical shape on the outer periphery of the rod-shaped member to generate electric resistance heating.
