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 becomes dirty due to the adherence of the surimi or the salt contained therein, the electrode surface is corroded or oxidized, and the surimi itself becomes dirty. 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 and moistened, the film is removed from the electrode. The surimi can be energized via the water, and when the surimi itself contains a large amount of water, the water in 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,
Since the electrode does not come into direct contact with the surimi, it is possible to prevent dirt from the surimi from adhering to the electrode surface, prevent corrosion and oxidation of the electrode surface, and 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 the above, an apparatus as schematically shown in FIGS. 8 and 9 is proposed.

That is, in FIGS. 8 and 9, the plate-shaped kamaboko 1 as a food material is placed on a tray 2, and the tray 2 is slidably placed on a horizontal traveling bed 31. . Tray guides 32 for guiding the side surface of the tray 2 are provided at upper portions on both sides of the traveling bed 31. And the tray 2 by the pusher (not shown)
The tray 2 can be intermittently moved along the horizontal direction (that is, the direction perpendicular to the paper surface of FIG. 8) by pushing in the horizontal direction. Therefore, the tray 2 on which the plate-shaped kamaboko 1 is placed, the traveling bed 31, and the tray guide 32 form a conveyance system path for conveying the plate-shaped kamaboko 1 in the horizontal direction. As shown in FIG. 9, the tray 2 has a plurality of recesses 2A formed in the width direction (that is, a direction orthogonal to the transport direction) on its upper surface, and one recess is provided in each recess 2A. Each one is made to hold and hold the plate-shaped kamaboko 1. The width W of the tray 2 is made shorter than the length L of the plate-shaped kamaboko 1, and both ends of the plate-shaped kamaboko 1 are trays 2.
It is placed so as to project outward from both edges in the width direction.

A pair of electrodes 3A and 3B are arranged on both sides of a predetermined position in the transport system path in the horizontal direction so as to face both sides of the plate-shaped kamaboko 1 on the tray 2 in the horizontal direction.
A and 3B are forward / backward drive mechanisms 4 such as fluid pressure cylinders.
A and 4B are configured so that they can be moved toward and away from each other. Further, a strip-shaped long water-permeable film 5A, 5B made of cellophane or the like is disposed between the transport system path and the left and right electrodes 3A, 3B so as to be vertically movable. This water permeable film 5
A and 5B are drawn out from the feeding rolls 6A and 6B arranged below the electrodes 3A and 3B, pass through the water tanks 7A and 7B for wetting, and then the electrodes 3A and 3B and the plate-shaped kamaboko 1 to the position between the electrodes 3A, 3
Winding rolls 8A and 8B arranged above B are wound up.

Here, if the electrodes 3A and 3B are moved forward as shown by the phantom lines in FIG. 8 with the tray 2 stopped and the water permeable films 5A and 5b stopped, the plate-shaped kamaboko 1 The electrodes 3A, 3 with the water-permeable films 5A, 5B interposed on the left and right sides of the surimi 1B on the plate 1A in FIG.
B is pressed, and an electric current flows from the electrodes 3A, 3B through the water-permeable films 5A, 5B into the surimi 1B, and is electrically heated. After heating, the electrodes 3A and 3B are retracted, and then the take-up rolls 8A and 8B are rotated by a predetermined number of rotations or rotation angles.
Runs upwards for a certain distance and its water-permeable film 5
The unused portions of A and 5B are located at the portions corresponding to the electrodes 3A and 3B. Therefore, when a new plate-shaped kamaboko is placed between the electrodes by the tray 2 along the transport system path and the surimi of the plate-shaped kamaboko is heated electrically, it is not used in the water-permeable film. A new part 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.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, the plate-shaped kamaboko heating device by electric heating shown in FIG. 8 and FIG. 9 has an excellent advantage, but the inventors of the present invention put it into practical use. After repeating the experiment and examination, the following problems were found.

That is, in the apparatus shown in FIG. 8 and FIG. 9, a tray is used as a transport member for placing the plate-shaped kamaboko and transporting it horizontally, and the tray is pushed forward by a pusher. However, in such a structure, after discharging the plate-shaped kamaboko after completion of electric heating from the tray on the outlet side of the heating device, another tray is provided to return the empty tray to the inlet side of the heating device again. Tray returning means must be provided, which complicates the device and increases the number of drive sources. In addition, such a complicated device and a large number of power sources cause an increase in cost and troublesome maintenance and inspection. Furthermore, in the equipment that handles food materials such as Kamaboko with a plate, since it is strictly required to be clean from the viewpoint of hygiene management, it is necessary to perform regular cleaning and sterilization. The complicated device causes a problem that cleaning and sterilization are not easy at all.
