DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a technique for heating a kneaded product formed into a cylinder using fish meat or the like as a raw material according to the present invention.

[0002]

2. Description of the Related Art When manufacturing a cylindrical kneaded product having a through hole in the center, a paste-like kneaded product formed by grinding a food material together with a seasoning or the like is adhered to a rod-shaped electrode, and the outer peripheral surface of the kneaded product is manufactured. Japanese Patent Application Laid-Open No. 9-47261 discloses a technique in which electric power is supplied between a plate electrode and a rod electrode in contact with each other to generate Joule heat in the kneaded product and heat the kneaded product. Has been developed.

[0003]

As described above, when the kneaded product is heated by supplying electric power to the plate-shaped common electrode with which the outer peripheral surface of the cylindrical kneaded product is in contact and the respective bar-shaped electrodes. In this method, one of the power supply terminals is always connected to the common electrode, and the power supply member is brought into contact with the rod-shaped electrode within a predetermined heating stroke.

Therefore, when the rod-shaped electrode is conveyed by the heating stroke, the heating of the kneaded product is completed, and the rod-shaped electrode is separated from the power supply member.
At this time, a spark may be generated between the rod-shaped electrode and the power supply member. When the spark is generated, not only does the rod-shaped electrode and the power supply member wear, but also the rod-shaped electrode becomes dirty, and when the rod-shaped electrode is removed from the kneaded product, there is a possibility that the kneaded product may be stained. In addition, there is a problem in that it takes time to clean the rod-shaped electrode that is repeatedly used in circulation and the heating efficiency is reduced.

If the rod-shaped electrode is separated from the power supply member in a state where the power supply from the power supply is stopped, no spark is generated, but power cannot be supplied to other rod-shaped electrodes. Therefore, the present inventor has conducted various studies on the timing of stopping the energization under the state where power is supplied. It was found that no spark was generated between the common electrode and the common electrode. By separating the kneaded product from the common electrode and subsequently separating the rod-shaped electrode from the power supply member, no spark was generated between them. Therefore, when the energization is stopped by separating the kneaded product from the common electrode, it is possible to prevent the generation of dirt on the rod-shaped electrode due to the generation of sparks, and to prevent the generation of dirt on the kneaded product and to obtain a high-quality kneaded product. Was found to be able to be efficiently heated.

An object of the present invention is to prevent a spark from being generated in a rod-shaped electrode when heating a cylindrical kneaded product so that a high-quality kneaded product can be efficiently heated.

The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the scope of the invention.

For example, two kneaded products P are wound around one rod-shaped electrode 21 and two cylindrical kneaded products P are simultaneously wound.
Is manufactured, but one rod-shaped electrode 21 is
It is also possible to wind three kneaded products. Although a chain with claws is used as the rod-shaped electrode transporting means for transporting the rod-shaped electrodes 21, various means such as a belt-type conveyor may be used. further,
