Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to the case where insulating containers filled with food materials are rolled and transferred one after another in one direction. The present invention relates to a container for producing electrically processed foods that automatically applies electricity uniformly up to temperature to sterilize electrically heated foods and promotes mass production of electrically processed foods that have good taste.

Conventional technology Conventionally, energization processing is used to mass-produce energized processed foods with good taste by sterilizing processed materials filled and housed in an insulating thin film packaging cylinder while still being packaged using energization. A food manufacturing container is well known, having been described in, for example, Japanese Patent Publication No. 52-28869 prior to this application, and will be explained with reference to FIGS. 6 and 7. That is, a packaged product 4 is obtained by filling and storing the processed material 3 in an insulating thin film packaging cylinder 2 with both sides open. Next, this packaged product 4 is housed in an insulating container 1 that is open on both sides, and an electrode tube whose surface is covered with a cloth 6 or the like soaked in salt water is placed in the open side of the packaged product 4 on both sides. 5 and 5 respectively to bring the cloth 6 side and the processed material 3 into close contact,
The open portions on both sides of the insulating container 1 are covered with conductive lids 8, 8 having bullets 7, 7, respectively, and the bullets 7, 7 are elastically installed in the electrode tubes 5, 5, and further insulated. A heat detection window 9 is provided on the circumferential surface of the container 1, and a heat sensitive element 10 and a thermocouple 11 are placed in close contact with the heat detection window 9. When the product is manufactured through the process, the current flow is automatically cut off to maintain the proper current state, allowing a good product to be produced while saving electricity, and speeding up the process of increasing the ripening temperature of processed materials. It detects and monitors the finished state of the product, further improving worker safety.

Problems to be Solved by the Invention By the way, in the case of the above-mentioned well-known energized processed food production container, if mass production is attempted while energized processed food is packaged, the processed material will inevitably be contained within the thin film packaging cylinder. In addition, it requires skill to fill processed materials containing a lot of moisture into thin film packaging cylinders one by one, and it may be difficult to increase efficiency. After that, both sides of the thin film packaging cylinder become wet with water, which opens both sides, and this makes it even more difficult to insert the electrode cylinder inside, making it difficult to mass-produce it in a short time. Can not.

In addition, the electrode tubes are fitted into the openings on both sides of the thin film packaging cylinder filled with the processing material, and the conductive lid and the electrode tube are connected via an elastic mechanism, so the processing material For some reason, part of the end of the insulating thin film packaging cylinder was bent inward during the filling process or the insertion process of the electrode cylinder, and the bent piece covered part of the surface side of the electrode cylinder. When this happens, the processed material in the covered area is no longer energized, resulting in poor energization and premature heat sterilization, making it difficult to mass-produce energized packaged foods with constant quality. Of course, it is not possible to detect the ripening temperature of the processed material, but the heat-sensitive body is not brought into direct contact with the processed material, but is instead brought into contact with a glass material that is highly heat resistant and thermally conductive. When applying electricity to processed materials, the body was manually placed against a heat detection window, one at a time.
It has not been possible to more accurately detect the ripening temperature of the processed material during electrical processing and to automate the ripening temperature detection work, and various problems have arisen in mass production.

Means for Solving the Problem The present invention solves the above problems, and includes:
The contents will be explained below using FIGS. 1 to 5 corresponding to the embodiment. That is, an insulating container 101 is provided which is filled with the food material A and whose outer shape is formed into a cylindrical shape so as to be able to roll freely.

The openings provided on both sides of the insulating container 101 are respectively covered by conductive lids 102 and 103 that are removably fitted. And the respective conductive lids 102, 103
There is an electrode 110 in close contact with the food material A,
111, bullets 118, 119 and electrode support 11
4,115 so that it can freely move.

A pair of conductive rings 120 and 121 are wound around the outer circumferential surface of the insulating container 101 at intervals, and are in sliding contact with fixed contact pieces 125 and 126 arranged in advance. The insulating container 101 between the conductive rings 120 and 121 has both ends connected to the conductive rings 120 and 121, respectively, and the inner surface is exposed in the insulating container 101 so as to be in close contact with the food material A. It is constructed by embedding a detection sensor 122.

Operation Now, the raw food material A is filled and contained in the insulating container 101 with both sides open. Next, conductive lids 102 and 103 are fitted to both open sides of the insulating container 101 to cover them. Then, the insulating container 101 between the left and right pair of salt-containing water contact bodies 108 and 109

The electrodes 110 and 111 which are respectively moved toward the food material A side due to the explosive force of the electrodes 119 are pinched and pressed, and the electrodes 110 and 111 are connected to the food material A by the salt-containing water electrical contact 1.
08, 109, respectively, and the conductive lids 102, 103 and the electrodes 110,
111 are connected to each other by electrode supports 114 and 115, and therefore the filled food material A is electrically conductive with the conductive lids 102 and 103 on both the left and right sides.

On the other hand, a ripening temperature detection sensor 122 is embedded in the insulating container 101 so that both ends are connected to conductive rings 120 and 121 wrapped around the outer circumferential surface of the insulating container 101, and the inner surface is exposed inside the insulating container 101. Therefore, the ripening temperature detection sensor 122 is also brought into direct contact with the food material A.

Therefore, in the process of sequentially and intermittently rolling a large number of insulating containers 101 configured as described above on the insulating rail 127 tilted to one side, a preset current-carrying piece is removed. 123,
124 are brought into contact with the conductive lids 102, 103 on both the left and right sides to apply electricity across the conductive lids 102, 103, and at the same time, the fixed contact pieces 125, 126 are brought into sliding contact with the pair of conductive rings 120, 121, respectively.

Then, the current flows through one conductive lid 102 and electrode 1.
10 and a salt-containing water contact member 108 that passes uniformly through the food material A, and a salt-containing water contact member 109 on the opposite side;
Electricity is applied to the electrode 111 and the conductive lid 103, and the food material A is sterilized by heat sterilization within a short time with the generated Joule heat. When the ripening temperature detection sensor 122 accurately detects that the food material A has reached the predetermined ripening temperature, the power to the current-carrying pieces 123 and 124 is automatically cut off, and the food material A has a good flavor and taste. A packaged electrically processed food can be quickly obtained. Therefore, as mentioned above, the insulating container 101...
. . . by simply rolling and moving them one after another along the inclination direction, the current-carrying pieces 1
23 and 124 are also a pair of left and right conductive rings 120,
Fixed contact pieces 125 and 126 are automatically brought into sliding contact with 121 to sterilize food material A by ripening, and then when food material A reaches a predetermined ripening temperature, current-carrying pieces 123,
By cutting off the power supply to 124, it is possible to continuously produce the energized processed food. Even if the food material A expands due to Joule heat during the heat sterilization process as described above, the left and right electrodes 11
Since the particles 0 and 111 are loosely moved to the conductive lids 102 and 103 under the pressure of the bullets 118 and 119, the food material A is imparted with appropriate firmness, and a moderately firm electrically processed food is obtained.
