Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for heating a kneaded product formed into a tubular shape by using fish meat as a raw material.

[0002]

2. Description of the Related Art When manufacturing a cylindrical kneaded product having a through hole in the center thereof, a paste formed by mashing a food material together with seasonings and the like is attached to a stick material, which is protected against gas, electricity, etc. It is used as a heating source for heating.

[0003] Conventionally, when heating a cylindrical kneaded product, the rod material is heated from the outer peripheral surface of the kneaded product by gas, electricity or the like while being transported while attached to a conveyor. In some cases, even if the surface is burned, the inside may not be sufficiently heated. Therefore, it is necessary to increase the conveying distance of the conveyor and gradually increase the heating temperature.

After the heating is completed, the rod material is extracted from the kneaded product, whereby a tubular kneaded product such as a bamboo ring having a through hole in the center is produced, but the kneaded product bites the rod material. The kneaded product tends to shrink in the shortening direction when the bar is pulled out. In particular, if the material is excessively heated, the tendency of the kneaded product to bite into the bar material becomes strong.

[0005]

Therefore, conventionally, in order to heat a cylindrical kneaded product, not only is it difficult to control the temperature of gas, electricity, etc. required for heating, but also to use a relatively large facility for heating. However, there is a problem that it takes a long time to complete the heating, which is a bottleneck in improving the productivity of the kneaded product.

Therefore, the present inventor has studied a technique for rapidly heating a cylindrical kneaded product, and energizes the cylindrical kneaded product by using a rod for forming a through hole in the kneaded product as an electrode. Thus, an experiment was conducted in which Joule heat was generated and heated in the kneaded product itself.

As a result, when the bar material for forming the through holes in the kneaded product is used as an electrode, electric power is supplied from that part, and even in the part near the bar material, which is the central part of the kneaded product, it is sufficient. Since it can be heated to a desired temperature and water can be kept on the surface of the bar, it has been found that the bar or electrode can be easily extracted from the kneaded product after the heating is completed. As in the past, when heating the product by gas or electricity from the outside of the kneaded product with the kneaded product attached to a metal bar, it is difficult to sufficiently heat the portion of the kneaded product that comes into contact with the bar. It was not easy to control the temperature by gas, electricity, etc. to sufficiently heat the material in the vicinity of the material, but if Joule heat is generated in the kneaded product itself and heated, the portion of the through-hole of the kneaded product is heated. Was found to be able to be sufficiently heated to a desired temperature in a short time.

As described above, when the kneaded product is heated by using the bar material for forming the through-holes in the kneaded product as an electrode, moisture is supplied to the outer peripheral surface of the kneaded product, but the whole kneaded product is uniformly heated. In order to obtain a high quality product, it is important to set the water content to a predetermined amount.

An object of the present invention is to use a rod material for forming a through hole of a cylindrical kneaded product as an electrode, and to generate a Joule heat in the kneaded product itself to heat the kneaded product into a desired amount of water. In order to be able to replenish, it is possible to heat a high quality tubular paste product.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

The upper surface of is a current-carrying surface for supplying electric power to the kneaded product 4, and is formed by a quadrilateral edge portion 1a and a water storage portion 1b inside thereof. 1b is formed lower than the edge 1a. Therefore, by supplying water into the water containing portion 1b, the water layer 23 is formed in the water containing portion 1b.

The rod-shaped electrode 3 by the chain conveyors 5 and 6
