Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an apparatus for manufacturing paste products such as kamaboko (kamaboko).

Conventional technology Pasted products such as kamaboko are usually made by grinding fish meat mixed with salt, adding auxiliary ingredients such as seasonings and starch, and molding the resulting surimi material into a predetermined shape. It is made by heating a molded product to gel it, and then grilling it if necessary. Among these manufacturing processes, the process of molding surimi into a desired shape involves filling a mold with surimi and pulling it out from the mold, or punching surimi with a predetermined mold. The process employed methods such as external heating using steam or hot water, and internal heating using the Joule heat generated by energization. Conventionally, in order to perform molding and heating at the same time, an insulating cylindrical body is filled with surimi, which is then pressed and molded using a pair of electrodes.
A possible method is to simultaneously apply electricity and heat the molded product using Joule heat.

Problems to be Solved by the Invention In the method of externally heating molded surimi products, it is often difficult to sufficiently heat the inside of the molded product, and in such cases, a so-called return phenomenon occurs, causing the product to deteriorate. There is an inconvenience that elasticity is lost.

In addition, in the method of heating a molded product, in order to prevent deformation of the molded product by bringing the electrode into contact with the molded product, the molded product is placed in a moisture-permeable bag such as cellophane paper in advance, and the bag is sandwiched between electrodes and energized.・
A common method is heating. This requires the work of placing the molded product in a bag and the work of removing the molded product from the bag in order to brown marks after heating, resulting in an increase in man-hours and manpower, which poses the problem of increasing costs. Ta.

The above two methods have the problem that the production efficiency is not necessarily good because the surimi molding process and the heating process are separate processes. With this method, manufacturing efficiency can be improved.
However, when molding and heating are performed using electrodes, if the electrodes are brought into direct contact with the surimi, the surimi may adhere to the electrodes, damaging the shape of the molded product, or dirt may gradually accumulate on the electrodes. This causes problems such as adhesion to products. In order to prevent such inconveniences, it is conceivable to place the molded product in a moisture permeable bag in advance and interpose a moisture permeable thin film between the electrode and the molded product. Not only is it troublesome to take it in and out of the molded product, but the liquid that seeps out from the molded product adheres to the electrode, and as the water evaporates, solid content gradually accumulates and becomes dirty. The problem arises that the dirt adheres to the product. In order to prevent such problems, it may be possible to configure the electrical surface to be brushed at predetermined cycles, but brushing causes dirt to scatter around, resulting in a worsening of the working environment and the adhesion of scattered objects to the product. There is a high risk that the quality will deteriorate.

The present invention was made against the background of the above-mentioned circumstances, and an object of the present invention is to provide an apparatus capable of efficiently manufacturing a paste product without impairing the quality of the product.

Means for Solving the Problems In order to achieve the above object, the present invention includes a pair of electrodes that approach and separate from each other, and a side surface facing these electrodes that is open all the way, and the opening is connected to the electrode. an insulating mold having a hollow part that is sealed and a material injection hole extending from the outer surface to the hollow part; a moisture-permeable thin film disposed between the electrode and the mold so as to be freely movable in a fixed direction; The sheet material provided with aluminum provided on the electrode side surface of the moisture permeable thin film and the mold are reciprocated along the running direction of the sheet material between the electrodes and a predetermined position removed from between the electrodes. The apparatus is characterized by comprising a moving means and a nozzle inserted into a material injection hole of a mold located between the electrodes to inject the dough material into the hollow part.

Operation In the apparatus of the present invention, the material for the dough product is filled into the hollow part of the mold while the mold is positioned between a pair of electrodes. In other words, when the mold is located between the electrodes, the nozzle communicates with the material injection hole in the mold, so if the electrodes are brought close to each other here, the electrodes will be connected with the sheet material interposed. The mold is clamped and the hollow opening in the mold is sealed. If the dough material is sent out from the nozzle in this state, the dough material will fill the hollow part of the mold. That is, the dough material is shaped.
The material in the hollow portion, that is, the molded article, is in direct contact with the moisture permeable thin film forming the sheet material, and liquid seeping from the material permeates the moisture permeable material. On the other hand, aluminum is interposed between this moisture-permeable thin film and the electrode, so the electrode and the molded product are electrically connected via the aluminum and the liquid that has permeated the moisture-permeable thin film. . If current is applied between the electrodes in this state, the current will flow through the material in the hollow part of the mold, generating Joule heat and heating the molded product. After applying electricity for a predetermined period of time to perform heating, the current is stopped, and then the electrodes are separated from each other and retreated from the mold, and while the sheet material is running in this state, the mold is moved in the same direction as the sheet material, and then The sheet material is then separated from the mold and peeled off from the molded product, and in this state, the heated molded product is removed from the mold.

A material supply pipe 12 opening on the side is connected through the material supply pipe 12, and a material pump (not shown) connected to the material supply pipe 12 supplies the raw material for the paste product, that is, the paste-like surimi raw material M. .

A sheet material 13 running upward is arranged between the mold 5 and each electrode 9. This sheet material 13 is mainly intended to protect the electrode 9, and is made of a moisture-permeable thin film such as breathable paper (cellophane paper, fine brass, Japanese paper, etc.) to impart conductivity. It has a structure in which an aluminum sheet (or tape) is placed on the side surface, laminated, or integrated with aluminum by vapor deposition, etc., and this sheet material 13
is guided by a plurality of guide rolls 15 from a feed-out roll 14 held in the main body part 1 to the lower side of the mold 5 at the lower limit position, and from there passes through the front side of the electrode 9 and passes through the upper guide roll 16. Furthermore, the sheet material 13 is wound up on a take-up roll 18 held by the main body part 1 via another guide roll 17, and by intermittently rotating the take-up roll 18, the sheet material 13 is made to run at a predetermined pitch.

A second discharge conveyor 24 is provided, and a second grill burner 25 is disposed above the second discharge conveyor 24.

Next, the operation of the apparatus configured as described above will be explained.

First, a material supply pump is connected to the material supply pipe 12. The mold 5 and the mold holder 3 are lowered to the lower limit position by the actuator 8, the nozzle 11 is connected to the material injection hole 7, and each electrode 9 is advanced by the air cylinder 10 in this state. Electrode 9
First, the sheet material 13 stretched between the upper and lower guide rolls 15 and 16 is pressed, and the mold 5 is sandwiched between the sheet material 13 and the mold 5. the result,
The hollow part 6 in the mold 5 is sealed by the left and right electrodes 9 and the sheet material 13. In this state, paste-like surimi raw material M is sent out from the nozzle 11,
The hollow part 6 of the mold 5 is filled. In this case, since the surimi raw material M is fed from the lower side of the hollow part 6, the air in the hollow part 6 is discharged upward, and therefore, air is prevented from being mixed into the surimi raw material M. Further, as the liquid content of the surimi raw material M permeates into the moisture-permeable thin film of the sheet material 13 during filling, the electrode 9 and the surimi raw material M are electrically connected via the liquid content and the aluminum of the sheet material 13. Becomes conductive. Therefore, when a voltage is applied between each electrode 9, a current flows through the surimi raw material M filled in the hollow part 6 of the mold 5, and as a result, Joule heat is generated, so that the surimi raw material M is heated. be done. After energizing and heating for a predetermined period of time, the current is stopped, the electrode 9 is moved back from the mold 5, and then the mold 5 is raised together with the mold holder 3 by the actuator 8 while the sheet material 13 is being wound up. In this case, since the sheet material 13 is guided in a direction away from the mold 5 via the upper guide roll 16, as the mold 5 rises, the sheet material 13 is peeled off from the heated surimi raw material M. When the mold 5 has reached the upper limit position, the sheet material 13 has been completely peeled off, and the hollow portion 6 has been removed from the pusher 20.
Therefore, by advancing the pusher 20 by the discharge cylinder 19 here, the surimi material M that has been formed and heated in the mold 5, that is, the semi-finished product, is transferred to the discharge conveyor 21 side. It is extruded and removed from the mold. While the semi-finished product is conveyed by the discharge conveyor 21, it is heated as it passes under the grill burner 22, and is grilled on one side.Then, it is turned over by the reversing machine 23 and transferred to the second discharge conveyor. It will be posted on the 24th. Then, while being conveyed by the second discharge conveyor 24, a second searing burner 25 burns the other side of the semi-finished product.

After the semi-finished product has been extracted from the mold 5 as described above, while the semi-finished product is being transported, the mold 5 is lowered together with the mold holder 3 to the lower limit position by the actuator 8, and is in a state where they are separated from each other. The material injection hole 7 is positioned between the electrodes 9 of the nozzle 1.
Connected to 1. In this state, since the sheet material 13 is wound up to a predetermined size as described above, a new, unused portion of the sheet material 13 is located between the electrode 9 and the mold 5. Then, if the electrode 9 is advanced in the same way as in the case described above, the mold 5
The hollow part 6 of is sealed, and the surimi raw material M is filled therein from the nozzle 11. By repeating such steps, shaping and heating of the surimi raw material M can be performed continuously.

In the above embodiment, one product is obtained in one cycle, but the present invention is not limited to the above embodiment. It may be configured to obtain a product of In that case, the same number of electrodes, sheet materials, and pushers as the number of hollow parts will be arranged.

Effects of the Invention As is clear from the above description, according to the apparatus of the present invention, since the pair of electrodes constitutes a part of the so-called cavity in which the surimi raw material is formed, the surimi raw material can be formed and heated using Joule heat. The sheet material interposed between the electrode and the surimi raw material is made of a moisture-permeable thin film and aluminum.
Since it runs every cycle and always brings a new part into contact with the electrode and the surimi raw material, it prevents the surimi raw material from getting dirty or the electrode from getting dirty, and allows continuous operation for long periods of time. Product quality does not deteriorate even after aging, and of course there is no need to particularly clean or replace the electrodes, so maintenance and management of the device becomes easier.
