2. Description of the Related Art Conventionally, a raw material for marine animal raw materials mixed with salt evenly, a material for kneading livestock meat, or a mixed material obtained by mixing them is used as a dilute salt solution having a salt concentration lower than that of the material. Prior to the present application, a method for producing an electrically processed food, which is housed in a contained insulative container under a flooded condition and subjected to a heat sterilization treatment of the material by an electricity application, is disclosed in Japanese Patent Application Laid-Open No. 1-5037.
It is described in Japanese Patent Publication No. 5 and is publicly known.

By the way, in the conventional method for producing an electrically processed food of this kind, a pair of counter electrode bodies respectively disposed on the counter walls of an insulating container having a predetermined size have the same structure. Since it is provided in a state where it cannot be moved, for example, as shown in FIG. 6, a small amount of food material is housed in an insulating container, and a small amount of food is fed by the energizing action between a pair of opposing electrode bodies. When trying to sterilize the material by heat aging, due to the small amount of the food material contained,
It will settle on the bottom of the insulating container without contacting each other, and the amount of electricity to the food material will be significantly reduced compared to the amount of conductive liquid contained, that is, the conductive area, resulting in wasted current. There is a problem that a large amount of loss occurs and that the aging heat sterilization process takes a lot of time and that a uniform electroprocessed food cannot be efficiently produced.

According to the present invention, a pair of opposed electrode bodies can be moved to and approach the food material side in accordance with the amount of food material stored in the insulating container, and even a small amount of food material can be stored in the insulating container. Even when stored in, the food material is subjected to aging heat sterilization treatment for a short time without causing current loss, and a method for producing an electrically processed food capable of continuously producing a uniform electrically processed food and a method thereof. The purpose is to provide a device.

[0005]

In order to achieve the above object, in the method for producing an electrically processed food of the present invention, one or both of a pair of counter electrode bodies provided in an insulating container containing a conductive liquid. Is moved to the food material side in conformity with the amount of the food material to be stored under the flooded condition in the insulating container, and then the food material is subjected to heat sterilization treatment by the action of electricity.

Further, in the apparatus for producing an electrically processed food of the present invention, a plurality of fitting grooves are provided in the insulating container containing the conductive liquid, and a pair of counter electrode bodies are movably fitted in the fitting grooves. It was done.

[0007]

When starting the aging heat sterilization process of food materials, a large number of food materials having an arbitrary shape and having an appropriate amount of salt uniformly mixed therein are prepared. Next, a large number of food materials are submerged in an insulating container containing a conductive liquid having a salt concentration lower than the salt concentration of the food material while simultaneously fitting a pair of opposing electrode bodies into the respective insertion grooves. It can be stored under the table. By the way, when the amount of food material commensurate with the capacity of the insulating container is stored,
A large number of food materials contained between the pair of counter electrode bodies are allowed to come into contact with each other, or are brought into contact with the pair of counter electrode bodies. Therefore, if a current-carrying action is applied between a pair of opposing electrode bodies, the current flows evenly and in a concentrated manner in a large number of high-conductivity food materials containing salt with a high salt concentration using a conductive liquid as a current-carrying medium. The temperature of the food material itself is increased by the generated high temperature Joule heat, and the aging heat sterilization treatment is performed within a short time to obtain an electrically processed food having a good taste.

By the way, in the above-mentioned heat sterilization treatment work, when the food material having a smaller storage capacity of the insulating container as shown in FIG. The distance between the pair of opposing electrode bodies becomes longer, and a small amount of food material sinks to the bottom of the insulating container in a scattered manner, and the amount of electricity supplied to the food material is smaller than the amount of the conductive liquid stored, that is, the conductive area. It is remarkably reduced, and as a result, a lot of useless energization loss occurs and a long heat sterilization treatment time is required.
Therefore, as described above, when it is desired to sterilize a small amount of food material as compared with the capacity of the insulating container, as shown in FIGS. 3 to 5, a small amount of food consumption is required between the pair of opposing electrode bodies. In order to allow the materials to be stacked in a submerged state, one of the counter electrode bodies or both of the counter electrode bodies are inserted into each of the fitting grooves so that they can be moved and approached to the food material A. When stored, the food materials come into contact with each other or the food material comes into contact with the counter electrode body.
Therefore, if electricity is applied between a pair of opposing electrode bodies, even in a small amount of food material, the conductive liquid is used as a current-carrying medium evenly in the food material, and in a short time due to the Joule heat of the current flowing in a concentrated manner. It is one that is heat-sterilized. Therefore, one or both of the pair of opposing electrode bodies are moved and brought closer to the stored amount of the food material stored in the insulating container under the flooded condition at any time, and then the food material is stored and energized. By applying the effect, even food materials having different storage amounts can be efficiently heat-sterilized.

EXAMPLES Examples will be described with reference to the drawings. In FIG. 1 to FIG. 5, A is a raw aquatic animal that can be obtained at a low cost, for example, sardines, horse mackerel, saury, mackerel, and their slide materials, or a paste material for livestock animals such as grains, cows, pigs, or the like. These mixed materials are, of course, salt-containing materials other than the above or food materials such as ham and sausage packaged in a moisture-permeable membrane, and the food material A has a salinity concentration in order to enhance the energizing effect. The salt content can be mixed uniformly so as to be, for example, 2% to 3% to form an arbitrary shape, and seasonings or spices can be added if necessary. B is a conductive liquid having a salt concentration lower than the salt concentration of the food material A, for example, 0.1% to 0.2%, and the conductive liquid B is contained in an appropriate amount in the insulating container 1 having an appropriate shape. It The insulating container 1 is formed in a bottomed casing shape with an open upper surface, and a plurality of fitting grooves 4, 4 are formed at appropriate intervals on the inner surfaces of the opposing walls 2, 3 of the insulating container 1.

Is a pair of counter electrode bodies fitted in the fitting grooves 4 and 5 at the facing positions so as to be freely replaceable. The upper ends of the pair of counter electrode bodies 6 and 7 are for facilitating the replacement work. Handles 8 and 9 are provided. Therefore, when the food material A is fully stored in the insulating container 1, the pair of counter electrode bodies 6 and 7 are fitted into the fitting grooves 4 and 5 located at both left and right ends as shown in FIG. Due to the action, a large number of food materials A stored between the pair of opposing electrode bodies 6 and 7 are rapidly heat-sterilized, and when a small amount of food materials A is stored in the insulating container 1, a fitting groove is formed. One or both of the pair of counter electrode bodies 6 and 7 pulled out from FIG.
Or as shown in FIG. 5, the food material A itself is brought into contact with each other by replacing the food material A side with a fitting groove at an appropriate position so as to narrow the gap between the pair of counter electrode bodies 6 and 7. Alternatively, if a part of the food material A is brought into contact with the pair of counter electrode bodies 6, 7 and then the food material A is housed and subjected to a current-carrying action, even if the food material A is a small amount, Is concentratedly energized as a medium to the food material A having a high salt concentration through a conductive liquid having a low salt concentration, and is efficiently heat-sterilized in a short time. Therefore, the pair of counter electrode bodies 6,
It is possible to efficiently heat and sterilize an arbitrary amount of the food material A in a short period of time simply by merely performing the replacement transfer operation of 7. 7 to 9 show another embodiment of the apparatus for producing electrically processed food, in which the bottom fitting groove 10 is provided on the inner bottom surface of the insulating container 1a.
Further, the upper fitting grooves 11, 1 are formed on the upper edges of the opposing walls 2a, 3a.
1 are provided symmetrically. Fitting portions 12 that fit into the bottom groove 10 are respectively provided at the lower ends of the pair of opposing electrode bodies 6a and 7a, and upper fitting portions 13 that fit into the upper fitting grooves 11 and 11 are provided on both sides of the upper portion thereof.
13 is provided and configured. Therefore, at the time of movement, the counter electrode bodies 6a and 7a are slightly lifted and moved so as to be disengaged from the bottom fitting groove 10 and the upper fitting grooves 11 and 11, and then lowered to move the counter electrode bodies 6a and 7a to the bottom fitting groove 10 at the position. And the upper fitting grooves 11 and 11 may be fitted respectively. 1 kg of sardine surimi material having a salt concentration of 2% was formed into a large number of spheres, which were stored in an insulating container 1 having a volume of 5 kg containing 5 liters of a conductive solution having a salt concentration of 0.1%, The pair of counter electrode bodies 6, 7 are moved closer to the material side so that they are in contact with each other or a part of the material is in contact with the pair of counter electrode bodies 6, 7, and then the pair of counter electrode bodies 6, 7 When a current of 60V, 5A was applied for 5 minutes for 7 minutes, the temperature of the conductive liquid reached 75 ° C.
Further, the temperature of the sardine-slipping material was raised to 95 ° C., respectively, and the sardine-slipping material could be completely heat-sterilized in a short time.

Since the present invention has the method and apparatus as described above, it has the following effects. Move one or both of the pair of counter electrode bodies provided in the insulating container containing the conductive liquid to the food material side in conformity with the amount of the food material to be stored in the insulating container under the flooded condition. Since we made it accessible, even if the food material stored in the insulating container is small, you can use one insulating container without replacing the insulating container,
By simply moving and approaching a pair of counter electrodes, the contact between food materials and the contact between food materials and counter electrodes can be made good, the conductive area can be expanded, and the current can be concentrated on the food material through the conductive liquid. It may be possible to efficiently produce a uniformly energized processed food by energizing and terminating the ripening heat sterilization treatment work in a short time, or it is possible to prevent the occurrence of current loss. Moreover, since the pair of counter electrode bodies are inserted into the plurality of insertion grooves provided in the insulating container in a freely replaceable manner, the pair of counter electrode bodies can be easily moved and approached in accordance with the storage amount of the food material. Accurate heat sterilization treatment work can be performed.
