Description

[Detailed Description of the Invention] Industrial Field of Application This invention is intended to produce a fish paste, which is produced by molding a fish paste such as fish meat on a plate and producing the product with the plate. The present invention relates to a device for heating surimi by Joule heat generated by energizing surimi on a plate.

2. Description of the Related Art In the manufacturing process of a plate-shaped kamaboko, generally, surimi such as fish meat is kneaded and formed into a predetermined shape on a plate, and then heated. As one of the heating means in this case, recently, it has been attempted to use a heating device that utilizes Joule heat accompanying energization.

In a heating device using Joule heat, it is necessary to bring a pair of electrodes into contact with the surimi formed on a plate and to pass an electric current from the electrodes into the surimi, but the electrodes were pressed directly against the surimi. In this case, there is a problem that the surface of the electrode is soiled due to the adherence of the surimi or salt contained therein, and the surface of the electrode is corroded or oxidized, and the surimi itself is also contaminated. Therefore, it has been considered to interpose a water-permeable film such as cellophane between the surimi and the electrode. In this case, if the water-permeable film is previously dipped in water to be moistened, the film is removed from the electrode. It is possible to energize the surimi through it, and when the surimi itself contains a large amount of water, the water content of the surimi wets the water-permeable film, and the surimi can be energized from the electrode through the film. . And if a water-permeable film is interposed between the electrode and the surimi in this way, the electrode does not directly contact the surimi, so that the contamination by the surimi is prevented from adhering to the electrode surface and corrosion or oxidation of the electrode surface is prevented. It is also possible to prevent the surface of the surimi itself from becoming dirty.

By the way, as a food material heating device by Joule heat generation in which a water-permeable film is interposed between an electrode and a food material such as fish meat as described above, the present inventors have already disclosed in Japanese Patent Laid-Open No. 3-103155 (Japanese Patent Application No. 3-103155). (Head 1-314340)
In this, a device schematically shown in FIG. 8 is proposed.

That is, in FIG. 8, the plate-shaped kamaboko 1 that has been molded as a food material is placed horizontally on an appropriate conveying member 2 such as a tray or a belt conveyor, that is, in the direction perpendicular to the paper surface of FIG. Is intermittently transported along the transport system path, and the horizontal sides of the predetermined position in the transport system path face the horizontal sides of the plate-shaped kamaboko 1 on the transport member 2. Is provided with a pair of electrodes 3A and 3B, and the electrodes 3A and 3B are configured to be moved in directions toward and away from each other by advancing and retracting drive mechanisms 4A and 4B such as a fluid pressure cylinder. .
Further, a strip-shaped long water-permeable film 5 made of cellophane or the like is provided between the transport system path and the left and right electrodes 3A and 3B.
A and 5B are arranged so that they can travel vertically. The water-permeable films 5A and 5B are electrodes 3A and 3B.
Delivery rolls 6A and 6B arranged at a position lower than
Is taken out of the water tank, passes through the water tanks 7A, 7B for wetting, reaches the position between the electrodes 3A, 3B and the plate-shaped kamaboko 1, and is further arranged above the electrodes 3A, 3B. It is designed to be wound on 8A and 8B.

Here, the transport member 2 is stopped and the water-permeable film 5
If the electrodes 3A and 3B are moved forward as shown by the phantom lines in FIG. 8 with the running of A and 5B stopped, the water permeability of both sides of the surimi 1B on the plate 1A of the plate-shaped kamaboko 1 is increased. Electrodes 3A and 3B with films 5A and 5B interposed
Is pressed against the water-permeable film 5 from the electrodes 3A and 3B.
A current flows through the surimi 1B through A and 5B, and the surimi 1B is heated by energization. After the heating is completed, the electrodes 3A and 3B are retracted, and then the winding rolls 8A and 8B are rotated by a predetermined rotation number or a rotation angle, whereby the water-permeable films 5A and 5B run upward by a predetermined distance, The water-permeable film 5A,
The unused portion of 5B is located at the portion corresponding to the electrodes 3A and 3B. Therefore, when the following new plate-shaped kamaboko is positioned between the electrodes by the conveyance member 2 along the conveyance system path and the surimi of the new plate-shaped kamaboko is electrically heated, it is not used in the water-permeable film. The new part of the will be sandwiched between the electrode and the surimi. In other words, each time the electric heating is performed once, an unused portion of the water-permeable film that is not soiled is used, so even if the water-permeable film is soiled by contact with surimi, the soiling will not occur. It is possible to prevent the situation that the accumulated electricity does not adversely affect the next energization heating, and that the dirt of the film adheres to the electrode and the surface of the electrode is corroded or oxidized.

Problems to be Solved by the Invention As described above, the plate-shaped kamaboko heating device by electric heating shown in FIG. 8 has excellent advantages, but the present inventors have conducted experiments and studies for practical use. Repeatedly, it was found that the following problems exist.

That is, when the electrodes 3A and 3B are advanced and the water permeable films 5A and 5B are sandwiched between them, the electrodes 3A and 3B are pressed against the surimi 1B of the plate-shaped kamaboko 1 to be electrically heated. , 5B are in a state of being bent by being pressed in the lateral direction from the vertical state as shown by the phantom line in FIG. Then, after the electric heating is completed, the electrodes 3A and 3B are retracted. At this time, the pressing force from the side of the water-permeable films 5A and 5B is also released,
The vertical state is restored by the tension applied in the vertical direction of the water-permeable films 5A and 5B. However, the surimi 1B usually has a certain degree of adhesiveness on the surface, so that when the electrodes 3A, 3B are pressed against the surimi with the water-permeable films 5A, 5B sandwiched between them for electric heating, 5A and 5B may stick to the surface of surimi 1B with a certain binding force. In this case, when the electrodes 3A and 3B are retracted after the electric heating is finished and the water permeable films 5A and 5B are returned to the vertical state by the tension, the surimi 1B of the plate-shaped kamaboko 1 is permeable to water on either side. While sticking to the flexible film, the plate-shaped kamaboko 1 may move on the conveying member 2 in either the left or right direction, and in extreme cases, may fall from the conveying member 2. In addition, electric heating may cause microscopic scorching between the surface of the surimi and the surface of the water-permeable film. If such scorching occurs, the above-mentioned problems are more likely to occur.

If the plate-shaped kamaboko moves laterally on the conveying member at the end of the electric heating as described above, it is often impossible to smoothly carry out the subsequent conveyance or transfer to the next step. Further, if the plate-shaped kamaboko falls from the conveying member, it not only causes a failure of the apparatus, but also the line has to be stopped in order to remove the dropped plate-shaped kamaboko, resulting in a significant decrease in productivity.

The present invention has been made in view of the above circumstances, and an improved kamaboko heating device with a plate as shown in FIG. 8 is provided so that the plate and the water-permeable film are restored at the end of electric heating. It is an object of the present invention to provide a device capable of effectively preventing the attached hoop from moving or falling in the width direction of the transport system path.

Means for Solving the Problems In order to solve the above problems, in the present invention, a molded plate-shaped kamaboko is placed on a conveying member and conveyed horizontally along a predetermined conveying system path. And a pair of electrodes that can move toward and away from each other are arranged on both sides in the width direction at a predetermined position in the transport system path, and each electrode is disposed between the transport system path and each electrode. The water permeable film is arranged to be drawn out from the lower feeding roll and wound by the upper winding roll, and in the state where the water permeable film is interposed between the pair of electrodes at the predetermined position of the transport system path. In a plate-shaped kamaboko heating device in which the paste on the plate of the plate-shaped kamaboko is sandwiched from both sides and heated by energization heating, a plate-shaped kamaboko is provided on both sides in the width direction at the predetermined position in the transport system path. It is characterized in that stoppers for restricting both end positions of the plate are arranged.

In this invention, the water-permeable film may be any thin film having properties including water such as cellophane, paper, cloth, and non-woven fabric, and is usually a hydrophilic film, a water-absorbent film, or a water-retaining film. Various film materials or film materials, which are also referred to as a flexible film, can be used. In this specification, these films are collectively referred to as a water-permeable film.

In the plate-shaped kamaboko heating device of the present invention, the electrode of the plate-shaped kamaboko is interposed with the water-permeable film at both sides in the width direction at the predetermined position in the conveying system path for conveying the plate-shaped kamaboko in the horizontal direction. Stoppers for restricting both end positions of the plate of the kamaboko with a plate are provided on both sides of a position where electric heating is performed by being pressed against the surimi portion. Therefore, when the electrode retreats and the water-permeable film returns to the vertical position accordingly, after the electric heating is completed,
Even if the surimi of plate-shaped kamaboko sticks to the water-permeable film, the movement of the plate-shaped kamaboko in the width direction of the transport system is restricted by the stopper, so that the film can be restored while the surimi part is stuck to the water-permeable film. Along with this, it is possible to effectively prevent the plate-shaped kamaboko from moving in the width direction of the conveying system or dropping from the conveying member.
