Abstract

PURPOSE:To efficiently produce a fish-paste product of good quality by constructing a cavity from a pair of electrodes and a mold, placing sheet materials composed of moisture-permeable thin films and aluminum between the electrodes and a ground fish meat raw material and simultaneously carrying out forming and heating of the ground fish meat raw material. CONSTITUTION:Sheet materials 13 composed of moisture-permeable thin films and aluminum are placed between electrodes 9 and a mold 5 is sandwiched therebetween. In this state, a pasty ground fish meat raw material (M) is then filled from a nozzle 11 through a material injection hole 7 into a hollow part 6 of the mold 5. At this time, since liquids exuded from the ground fish meat raw material (M) are permeated through the moisture-permeable thin films thereof, the electrodes 9 and the ground fish meat raw material (M) attain an electrically conductive state through the liquids permeated through the aluminum and moisture-permeable thin films. Thereby, if a voltage is applied across the respective electrodes 9 to flow a current through the ground fish meat raw material (M), which is then heated. The current is subsequently stopped to mutually separate and retreat the electrodes 9 and run the sheet materials 13. The sheet materials are subsequently isolated from the mold 5 and peeled from the obtained formed product. Thereby, in this state, the formed product after completing the heating is taken out of the mold 5.

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 Techniques Pasted products such as Nhoko are usually made by grinding fish meat mixed with salt, adding auxiliary materials such as seasonings and starch, and shaping the resulting surimi material into a predetermined shape. It is made by heating the molded product to gel it, and then baking it if necessary. Among these manufacturing processes, the process of molding the surimi into a desired shape involves filling a mold with the surimi and pulling it out from the mold, or punching the surimi with a predetermined mold, and also involves a heating process. Methods such as external heating using steam or hot water, and internal heating using Joule heat caused by energization were adopted. Conventionally, in order to perform molding and heating at the same time, the method used was to fill an insulating cylinder with surimi, pressurize it with a pair of electrodes, mold it, and simultaneously apply electricity to heat the molded product using Joule heat. It is considered.

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, so-called return rings occur and the product deteriorates. There is an inconvenience that the elasticity of the material is lost.

In addition, in the Joule heating method for molded products, in order to prevent deformation of the molded product due to contact of the electrode with the molded product, the molded product is placed in a moisture-permeable bag such as cellophane paper in advance.
A common method is to sandwich this between electrodes and energize and heat it. As a result, it is necessary to put the molded product into a bag and take it out of the bag after heating to give it a brown mark, which increases the number of man-hours and manpower, which leads to an increase in costs. there were.

The above two methods have the problem that the production efficiency is not necessarily good because the surimi forming process and the heating process are separate processes.・The heating method can improve manufacturing efficiency.

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 moisture-permeable 1llF1 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 seeping out from the molded product adheres to the electrode, and as the water evaporates, solid content gradually accumulates and becomes dirty, and as molding and heating are repeated. A problem arises in 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 risk of particles adhering to the product. There is a high risk that the quality will deteriorate.

This invention was made in view of the above circumstances, and it is an object of the present invention 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 opened by the electrodes. An insulating mold having a hollow part that is sealed and having a material injection hole extending from the outer surface to the hollow part, and a moisture permeable thin film disposed between the electrode and the mold so as to be freely movable in a fixed direction. A sheet material provided with aluminum provided on the electrode side surface of the wet 77iWA, and a moving means for reciprocating the mold along the running direction of the sheet material between the electrodes and a predetermined position removed from between the electrodes. and a nozzle that communicates with the material injection hole of the mold located between the electrodes and injects 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 fill the mold with the sheet material interposed. By pinching, 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 the moisture permeable thin film and the electrode, and therefore the electrode and the molded product are electrically connected via the aluminum and the liquid that has permeated the moisture permeable S film. If current is applied between each electrode in this state,
Electric current flows through the material inside 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 in this state, the sheet material is run, and the mold is moved in the same direction as the sheet material,
Thereafter, the sheet material is separated from the mold and peeled off from the molded product, and in this state, the heated molded product is removed from the mold.

The mold holder 3 is for holding a mold 5 that is filled with a paste product material, that is, a paste-like raw material to be molded into a predetermined shape, and an example of the mold 5 is shown in Fig. 3. be. That is, the mold 5 is a frame-shaped member having a hollow part 6 opening on the left and right sides, and is made of an insulating material or has an insulated structure, and the lower end part has a hollow part 6 opened from the bottom surface. A material injection hole 7 extending up to 6 is formed. The mold holder 3 is connected to an actuator 8 serving as a moving means, such as an air cylinder arranged vertically in the main body part 1.
It is configured so that it can be moved back and forth between two positions in the vertical direction.

A pair of electrodes 9 are arranged close to each other and separated from each other with the mold 5 at the lower limit position sandwiched therebetween. This electrode 9 is set in a shape that covers the open end of the hollow part 6 in the mold 5 and seals the hollow part 6. In other words, the electrode 9 has a tip area larger than the opening area of the hollow part 6. cylinder 10
It is attached to the tip of the rod so that it can move freely forward, and is connected to a predetermined power source.

Further, on the upper surface of the main body part 1, a nozzle 11 is arranged upward, which is connected to the material injection hole 7 of the mold 5 at the lower limit position while maintaining an airtight state. A material supply pipe 12 which passes through and opens on the side thereof is connected, and a material pump (not shown) connected to the material supply pipe 12 supplies the raw material for the paste product, that is, the pasty 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 in order to impart conductivity, the surface of the electrode 9 side of a moisture-permeable thin film such as breathable paper (cellophane paper, Fine Plus, Japanese paper, etc.) is used. An aluminum sheet (or tape) is arranged, laminated, or integrated with aluminum by steaming etc.*a, and this sheet material 13 is rolled out from a plurality of feed rolls 14 held in the main body part 1. It is guided to the lower side of the mold 5 at the lower limit position by the guide roll 15, passes through the front side of the electrode 9, passes through the upper guide roll 16, and then passes through another guide roll 17 to be held in the main body part 1. The sheet material 13 is wound around a winding roll 18, and by intermittently rotating the winding roll 18, the sheet material 13 is made to run at a predetermined pitch.

At the upper end of the gate-shaped support 2, that is, at a position facing the mold 5 placed at the upper limit position, a bushing 20 is arranged to be moved back and forth by a discharge cylinder 19 toward the hollow portion 6 of the mold 5. In addition, a discharge conveyor 21 is arranged on the opposite side of this bushing 20 across the mold 5, facing away from the mold 5, and above the discharge conveyor 21, the product on the discharge conveyor 21 is heated and baked. 1st to add

is provided, and a second grill burner 25 is arranged 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. The electrode 9 first pushes the sheet material 13 stretched between the upper and lower guide rolls 15 and 16, and then sandwiches the sheet material 13 between the mold 5 and the mold 5. the result,
The hollow part 6 in the mold 5 contains the left and right electrodes 9 and the sheet material 1.
It is sealed by 3. In this state, paste material M is sent out from the nozzle 11 and filled into the hollow part 6 of the mold 5. In that case, since the raw material M for scraping is fed from the lower side of the hollow part 6, the air in the hollow part 6 is discharged upward, and therefore, the mixing of air into the raw material M for scraping is prevented.

In addition, as the liquid valve of the raw material M permeates into the moisture-permeable thin film of the sheet material 13 during filling, the electrode 9 and the raw material M are electrically connected to each other through the liquid valve and the aluminum of the sheet material 13. becomes electrically conductive. Therefore, when a voltage is applied between each electrode 9, a current flows through the raw material M filled in the hollow part 6 of the mold 5, and Joule heat is generated accordingly, so the raw material M is heated. be done.

After energization and heating have continued 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 that case, the sheet material 13 is guided in the direction away from the mold 5 via the upper guide roll 16, so as the mold 5 rises, the sheet material 13 is peeled off from the heated raw material M. . When the mold 5 reaches the upper limit position, the sheet 4i113 has been completely peeled off, and the hollow portion 6 is positioned opposite the pusher 20, so that the pusher 172
By advancing the 0 with the ejection cylinder 19,
The surimi material M that has been molded and heated in the mold 5, that is, the product, is ejected to the discharge conveyor 21 side and extracted from the mold. While the 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.The product is then turned over by the quick reversing machine 23 and transferred to the second discharge conveyor 24. It will be posted on.

Then, while the product is being conveyed by the second discharge conveyor 24, a second searing burner 25 burns the other side of the product.

After the product is extracted from the mold 5 as described above, and while the product is being transported, the mold 5 is lowered to the lower limit position together with the mold holder 3 by the actuator 8, and the electric current 4j9, which is spaced apart from each other, is lowered to the lower limit position by the actuator 8. The material injection hole 7 is connected to the nozzle 11. 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 hollow part 6 of the mold 5
is sealed, and the raw material M is filled therein from the nozzle 11. By repeating these steps, the molding and heating of the raw material M can be continuously performed.

In addition, 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. In that case, the same number of electrodes, sheet materials, and bushings as the number of hollow parts will be arranged.

Effects of the Invention As is clear from the above description, according to No. 81 of the present invention, since the pair of electrodes constitutes a part of the so-called cavity in which the raw material is formed, it is possible to form the raw material and utilize Joule heat. In addition, the sheet material interposed between the electrode and the material to be rubbed is made of moisture permeable aluminum and aluminum, and is run in each cycle. Since the new part is constantly brought into contact with the electrode and the raw material, it prevents the raw material from getting dirty or the electrode from getting dirty, and the product remains stable even after long periods of continuous operation. Since the quality is not impaired and, of course, there is no need to particularly clean or replace the electrodes, it is possible to obtain effects such as easier maintenance and management of the device.
