BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for electrically heating a molded fish meat paste when producing a paste product such as a kamaboko.

[0002]

2. Description of the Related Art Recently, a method has been developed in which electric heating is applied to a step of heating a molded surimi in the process of manufacturing a kneaded product such as kamaboko. This method will be explained in the case of a plate-shaped kamaboko. The fish meat surimi prepared by adding seasonings and the like is molded on the plate, and a sitting is given if necessary, and then the plate 1 is prepared as shown in FIG. A method in which the upper surimi molding 2 is sandwiched between a pair of electrodes 3A and 3B, an electric current is passed between the electrodes 3A and 3B, Joule heat is generated by the resistance of the surimi molding 2, and the surimi molding 2 is heated from the inside thereof. Is. According to such energization heating, it is possible to raise the temperature of the surimi compact in a relatively short time, and if the energization current is uniform, uniform heating is possible.

Since the ground meat before heating is still extremely soft and has a slight fluidity, when the electrodes 3A and 3B are pressed only to the portion of the ground body 2 on the plate 1, The surimi compact may be largely deformed by the pressure from the electrodes. Therefore, generally, as shown in FIG. 7, the dimensions and positions of the electrodes 3A and 3B are set so that a part of the electrodes 3A and 3B is a plate. It is usual that the first part is defined so as to face it, and the part of the plate 1 can receive the pressure of the electrodes 3A and 3B.

[0004]

When the electric heating is actually applied to the production of the plate-shaped kamaboko as described above, it has been found that the following problems occur. That is, as shown in FIG. 7, when both ends of the surimi molding 2 on the plate 1 bulge outward evenly outside the positions of both ends of the plate 1, the electrode 3
A and 3B can be entirely pressed against both end surfaces of the surimi molding 2, so that the current also flows relatively uniformly throughout the surimi molding 2 and uniform heating is possible. However, as shown in FIG. 8, for example, in the case where the upper portions of both ends of the surimi compact on the plate 1 are largely retracted in a curved shape due to the "drip" of the surimi, the electrodes 3A and 3B have the surimi compact 2 The situation may occur in which it cannot be pressed sufficiently onto the upper end face of the. In this case, almost no electric current flows in the upper part of the surimi compact, and that part is not sufficiently heated. Further, in this case, a spark may occur between the upper portion of the end surface of the surimi molding 2 and the electrodes 3A, 3B, and yellowing or browning may occur on the surface of the surimi molding 2 at that portion.

Further, for example, as shown in FIG. 9, both end positions of the surimi molding 2 on the plate 1 are the same as the both end positions of the plate 1 or, conversely, are pulled inward from the both end positions of the plate 1. In this case, even if the electrodes 3A, 3B are in contact with both ends of the plate 1, the electrodes 3A, 3B
3B does not abut uniformly, so that the electric current does not flow evenly in the surimi molding 1, resulting in non-uniform heating, or as described above, the sparks cause discoloration on the surface of the surimi molding. Sometimes.

The present invention has been made in view of the above circumstances. As a device for electrically heating a surimi molding in the process of manufacturing a paste product such as a kamaboko with a plate, the surimi without causing the above-mentioned problems. It is an object of the present invention to provide an electric heating device capable of uniformly heating a molded body and causing no spark.

SUMMARY OF THE INVENTION The present invention relates to an electric heating apparatus for sandwiching a molded fish meat paste from both sides with electrodes and heating the surimi by Joule heat by energizing between the electrodes. A sheet-like cushion material made of a material having water content and elastically compressible and deformable in the thickness direction is interposed between the body and the body, and the sheet-like cushion material is electrically conductive by being impregnated with an electrolyte solution. It is characterized in that it is configured to be imparted with sex.

[0008]

When the energization heating device of the present invention electrically heats the surimi molding, a sheet-like cushion material is interposed between the surimi molding and the electrode. This sheet-shaped cushioning material has water content, and conductivity is imparted by being impregnated with an electrolyte solution such as saline solution. Therefore, it is possible to energize the surimi molded body from the electrode through the sheet-shaped cushioning material. And since the sheet-shaped cushioning material is elastically compressible and deformable in the thickness direction, even when the upper end surface of the surimi molded body on the plate is greatly curved, for example, in the production of the plate-shaped kamaboko,
Due to the pressure from the electrodes, the sheet-shaped cushioning material is compressed and deformed following the shape of that portion, so that the sheet-shaped cushioning material comes into uniform contact with almost the entire end surface of the surimi compact. Therefore, the electric current from the electrode uniformly flows through the sheet-shaped cushion material to almost the entire surimi compact, and uniform heating is performed. In addition, when manufacturing a plate-shaped kamaboko, even if the end face position of the plate-shaped surimi molding is the same as the end face position of the plate or slightly retracted,
Due to the elastic compressive deformation of the sheet-like cushion material in the thickness direction due to the pressure from the electrode, the sheet-like cushion material uniformly contacts the end surface of the surimi compact, and the current from the electrode passes through the sheet-like cushion material. It flows evenly into the surimi compact and is heated uniformly.

Further, as described above, since the sheet-shaped cushioning material uniformly contacts the surimi molding, there is no possibility of sparks, and therefore discoloration is prevented.

Incidentally, in the case of manufacturing a kneaded product other than the plate-shaped kamaboko, it goes without saying that the same action as described above can be obtained. That is, when the surimi molded product without a plate is heated electrically, even if there is unevenness on the surface of the surimi molded product on the side facing the electrode, the sheet-shaped cushion material is pressed against that surface by compressive deformation of the sheet-shaped cushion material. The contact of the electrodes through the electrodes can be made uniform, so that an electric current can be evenly applied to perform uniform heating.

[0011]

1 to 3 show an electric heating apparatus according to a first embodiment of the present invention applied to the production of a plate-shaped kamaboko.

In FIGS. 1 and 2, a surimi molding 2 is molded on a plate 1 and is in a state with a plate.
The plate-formed surimi body 2 is placed on the belt 12 of the belt conveyor 10 at predetermined intervals, and is sequentially sent from the molding machine (not shown) to the electric heating device 11. Here, the width of the belt 12 is set to be slightly shorter than the length of the plate-formed surimi molded body 2, and therefore, both ends of the plate-containing surimi molded body 2 slightly project from the widthwise edges of the belt 12. It will be.

The electric heating device 11 includes a pair of belt electrodes 15A and 15B arranged on both sides of the belt 12 in parallel with the belt 12 and the belt electrodes 15A and 15B.
The sheet-shaped cushioning members 16A and 16B are wound around the outer periphery of the sheet-shaped cushioning members 16A and 16B. The belt electrodes 15A and 15B are made of, for example, titanium or a titanium alloy, and have pulleys 17A and 15A, respectively .
18A; 17B, 18B endlessly wrapped around,
It can be continuously rotated by a driving device such as a motor (not shown). As shown in detail in FIG. 3, the sheet-like cushion materials 16A and 16B are made of, for example, cotton or the like, and have two relatively permeable water-permeable outer cloths 1
A water-containing cushioning inclusion 19 made of non-woven fabric, absorbent cotton, or one or more towel cloths is sandwiched between 7 and 18 to form a multilayer structure.
Therefore, the sheet-like cushion materials 16A and 16B as a whole have a water content (a property capable of being impregnated with an aqueous solution) and can be elastically compressed and deformed in the thickness direction.

Further, on the back side of the belt electrodes 15A, 15B, a spray for impregnating a sheet-like cushion material 16A, 16B wound around the outer periphery of the belt electrodes 15A, 15B with a solution harmless to food as an electrolyte solution, for example, saline solution. Device 20
Is provided.

In the apparatus of the above-mentioned embodiment, the plate-formed surimi body 2 is sequentially mounted on the belt 12 and is transferred toward the electric heating device 11 as the belt 12 travels. It In the electric heating device 11, the plate-shaped surimi molding 2 has sheet-shaped cushioning material 16 formed by belt electrodes 15A and 15B having opposite end surfaces on both sides.
It is sandwiched via A and 16B. Here, the belt electrode 15
A, 15B and sheet-like cushioning materials 16A, 16B
Are circulated in synchronism with the running of the belt 12, and the sheet-shaped cushion materials 16A and 16B are impregnated with saline solution by the spray device 20, whereby the sheet-shaped cushion materials 16A and 16B are made conductive. Is given.

The surimi molding 2 is a sheet-like cushion material 1.
In the state of being sandwiched between the belt electrodes 15A and 15B via 6A and 16B, the current supplied between the belt electrodes 15A and 15B flows to the surimi molded body 2 via the sheet-like cushioning materials 16A and 16B, and the surimi molded body is formed. Heat is generated by the resistance of 2. At this time, the sheet-like cushion material 16
Since A and 16B can be elastically compressed and deformed in the thickness direction, even if the upper portion 21a of the end surface 21 of the surimi molding 2 is curved and retracted as shown in FIG. The cushion material 16A (16B) is compressed and deformed along the shape of the end surface 21 of the surimi molded body 2, and the sheet-shaped cushion material 16A (16B) also comes into uniform contact with the upper portion 21a thereof. Therefore, the electric current from the belt electrode 15A (15B) surely flows to the upper part of the surimi molding 2, and the electric heating is sufficiently performed also in the upper part. Further, for example, as shown in FIG. 5, the end surface 21 of the surimi molded body 2 has the plate 1
Even if the seat cushion 16A (16B) is retracted more than the end face position of the end face 21
The entire surface of the ground surface, and therefore the end surface 2 of the surimi molding 2
An electric current from the belt electrode 15A (15B) flows over the entire surface of 1, and as a result, the surimi compact 2 is uniformly heated.

As described above, the surimi molding 2 with a plate is
While being conveyed by the belt 12, the electric heating is uniformly performed while being sandwiched by the belt electrodes 15A and 15B via the sheet-like cushioning materials 16A and 16B, and then, when the belt electrodes 15A and 15B are disengaged, the electric heating is performed. Will not stop. Then, the surimi compact 2 with the plate after the heating is sent to the next packaging step or the like.

FIG. 6 shows a second embodiment of the present invention.
Also in this second embodiment, the surimi compact 2 with a plate
Is sequentially conveyed by the belt 12 of the belt conveyor 10 to the electric heating device 11, but the constitution of the electric heating device 11 is the same as that of the first embodiment shown in FIGS. Is different.

That is, the electrodes for energization in the electric heating device 11 are a pair of plate-shaped electrodes 30A and 30B facing each other on both sides of the belt 12, and these plate-shaped electrodes 30A and 30B are fluid pressure cylinders or the like. Forward / backward drive mechanism 3
It is possible to move back and forth in the direction toward and away from each other by 1A and 31B. And the sheet-shaped cushioning material 16
A and 16B are delivered from the delivery rolls 32A and 32B on one side of the plate-shaped electrodes 30A and 30B, and the plate-shaped electrode 3
0A, 30B, the plate electrodes 30A, 30B
It is adapted to be wound by the winding rolls 33A and 33B on the other side of B. The sheet-like cushion members 16A and 16B are provided with feeding rolls 32A and 32B.
At the position where the salt solution is fed out, the spray device 20 sprays a harmless electrolyte solution, for example, a saline solution onto the food to impregnate the saline solution.

In the second embodiment, the belt 12 of the belt conveyor 10 is driven intermittently. That is, the belt 12 travels with the plate electrodes 30A and 30B retracted, and the belt 12 travels with a predetermined number of plate-formed surimi bodies 2 positioned between the plate electrodes 30A and 30B. Stops once. And the plate electrode 30
A and 30B move forward to sandwich the plurality of surimi molded bodies 2 on the belt 12 from both sides thereof. At this time, as in the case of the first embodiment, the sheet-shaped cushion materials 16A and 16B are interposed between the plate-shaped electrodes 30A and 30B and the end surface of the surimi molded body 2, and as described above, the sheet-shaped cushion materials are used. 16
A and 16B are compressed and deformed, and evenly contact both end surfaces of the surimi molding 2. Therefore, the plate electrode 30A,
The current supplied between 30B is applied to the sheet-like cushion material 16
It flows evenly over the entire surimi molding 2 via A and 16B, and the electric heating is carried out uniformly.

In this way, the sheet-like cushion material 16
Electric heating is performed in a state of being sandwiched between the plate-shaped electrodes 30A and 30B via A and 16B, and when heating for a predetermined time is completed, the plate-shaped electrodes 30A and 30B retreat and traveling of the belt 12 resumes. The heated surimi molded body 2 with a plate is sent to the next packaging step or the like. Further, the sheet-like cushion materials 16A and 16B are wound rolls 33A and 33B.
Is wound by a predetermined length (more than the length of the plate electrodes 30A and 30B), and a new unused portion is replaced by the plate electrode 30.
It is positioned in front of A and 30B to prepare for the next heating. In the second embodiment, the feeding roll 32 for the sheet-like cushion materials 16A and 16B is used.
A, 32B and the winding rolls 33A, 33B are also synchronized with the plate electrodes 30A, 30B, or the plate electrodes 30.
It is usually configured to move forward and backward together with A and 30B.

In each of the above embodiments, the plate-formed surimi body 2 is transferred by the belt conveyor 11, but the transfer means is not limited to this, and for example, a tray and a pusher may be used. The surimi molding to be heated is not limited to the one with a plate, but it can be applied to surimi molding for various paste products, and a transfer means is also provided according to the shape and size of the surimi molding. It can be changed arbitrarily.

In each of the above-described embodiments, the spray device 20 is used as a means for impregnating the sheet-shaped cushioning materials 16A and 16B with an electrolyte solution such as saline.
For example, it goes without saying that the electrolyte solution may be dropped on the sheet-shaped cushion material, or the sheet-shaped cushion material may be dipped in the electrolyte solution tank.

Further, the sheet-shaped cushioning materials 16A, 1
6B has only the property of being capable of being impregnated with an electrolyte solution such as saline (hydrous) and elastically compressible and deformable in the thickness direction, and has a multilayer structure as described above. Although it is not limited to this, it is desirable to have a certain thickness or more in order to make uniform contact with the end surface of the surimi molding. Generally, in a free state (uncompressed state), a thickness of about 2 mm or 3 mm It is appropriate to have.

[0025]

According to the electric heating device of the present invention, when electric power is applied to the surimi molding, an electric current is evenly applied to the entire surimi molding regardless of the shape of the surface facing the electrode or the unevenness. Therefore, it is possible to effectively prevent the occurrence of local heating shortage, and
It is also possible to effectively prevent the occurrence of sparks due to poor contact during energization, which causes a product appearance failure due to discoloration.
