Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides raw food materials made from livestock or aquatic animals and plants, such as ham, sausage, and mixed materials of ground meat, fish meat, and grains, in a cylindrical shape. After being easily and quickly filled into food containers, these raw food materials can be heated and sterilized uniformly within a short period of time by uniform energization at any time to produce flavorful electrification-processed foods. Concerning electrified processed food containers.

Conventional technology Conventionally, raw food materials can be easily filled and stored, and the filling operation of a predetermined amount of food materials can be easily and quickly performed without requiring any skilled technology, and the food materials can be filled with electricity at any time. In order to easily achieve mass production of packaged foods by sterilizing them by heating, the whole has a heat-resistant and insulating cylindrical shape, the top is open, and a large number of energizing holes are arranged on the flat bottom surface. In addition, the electrically processed food container for packaged food has a structure in which a flange is provided on the open periphery,
It is well known, having been described in, for example, Japanese Patent Publication No. 59-41711 prior to the filing of this application.

Problems to be Solved by the Invention By the way, in the above-mentioned known energized processed food container, when energizing the raw food materials filled and housed, the upper side is energized from the entire surface of the upper open side. On the other hand, since the bottom side was energized through a large number of current-carrying holes drilled in the flat bottom surface, there may be a considerable difference between the current-carrying area on the top side and the current-carrying area on the bottom side. Due to the difference, the amount of current applied also differs, and when the amount of current applied is increased to sterilize packed raw food materials in a short period of time, the raw food materials located on the side of the current-carrying hole have a resistance to current flow. As a result, the product becomes burnt, resulting in a serious problem that not only the value of the product decreases, but also the taste.

Means for Solving the Problems Therefore, the technical problem of the present invention is to increase the energized area on the lower side while also holding the food container, thereby shortening the heat sterilization process and improving the quality of energized processed foods. There is a particular thing.

In order to solve this technical problem, the present invention has a structure in which the entire structure is cylindrical with heat-resistant insulation, and an upper current-carrying window with the entire surface open is provided at the top, and an upper current-carrying window is provided on the flat bottom surface. This electrically processed food container is characterized in that a lower current-carrying window having a current-carrying area slightly smaller than the current-carrying area is disposed with an appropriately shaped window frame remaining.

Effect The above technical means acts as follows (see Figures 1 and 2).

Now, if the food container 1 as shown in FIGS. 1 and 2 is filled with raw food material A made of aquatic animals obtained by adding salt from the upper current-carrying window 2 side and stirring and mixing, The food material A can be easily and quickly filled and contained without requiring any heating techniques. In this way, a predetermined amount of food material A
When the raw food material A is filled and housed, the lower current carrying window 4 provided on the bottom flat surface 3 of the food container 1 is closed with a salt water contact member 9, and the insulating storage frame 8 is closed while preventing the raw food material A from dripping. At the same time, the upper electrode plate 12 is placed on the upper current-carrying window 2 side via the salt-containing water contact body 11, and the lower electrode plate 10 is placed on the lower current-carrying window 4 side via the salt-containing water contact body 9. and upper electrode plate 1
Move down and press 2.

In other words, the salt water contacting bodies 11 and 9 located between the pair of upper and lower electrode plates 12 and 10 and the raw food material A are brought into close contact with each other, and the current carrying area of the lower current carrying window 4 is smaller than that of the upper current carrying window. 2, the current flowing between the pair of upper and lower electrode plates 12 and 10 is approximately equal. Therefore, if current is applied across the pair of upper and lower electrode plates 13 and 10, the current will uniformly flow through the raw food material A, and the heat sterilization will be carried out by the Joule heat generated by the uniform current resistance action. Even if a large amount of current is applied to shorten the process, the raw food material A on the lower current-carrying window 4 side will not burn.
It is successfully heat-sterilized and becomes a flavorful electrically processed food.

Embodiments Next, the structure of the electrically processed food container according to the present invention will be explained based on preferred embodiments shown in the accompanying drawings.

In Figures 1 to 3, 1 is a food container that can be easily filled with raw food materials A made from livestock or aquatic animals and plants, such as ham, sausage, and mixed materials such as ground meat, fish meat, and grains. The food container 1 is made of a heat-resistant insulating material and has a rectangular cylindrical shape as a whole, and has an upper current-carrying window 2 with its entire surface open at the top, and a flat bottom surface 3 that allows the upper current-carrying window 2 to be energized. A plurality of square-shaped lower current-carrying windows 4 having a current-carrying area slightly smaller than the current-carrying area are disposed with a square-shaped window frame 5 remaining, and
A flange 6 extending horizontally is provided at the periphery of the upper current-carrying window 2.
are integrated. Salt in an amount equivalent to about 2% of the raw food material A is added to the raw food material A, and the salt is stirred and mixed to promote the electrical conductivity and the food product. . 7 is a manufacturing device for manufacturing a rectangular electrically processed food using the food container 1,
In this manufacturing device 7, a salt-containing water electrical contact body 9, which is made of a fibrous material impregnated with salt water and molded, is placed on the open bottom side of a hollow cylindrical insulating storage frame 8 with both the top and bottom open. The food container 1 is fitted into the insulating storage frame 8 so that the bottom flat surface 3 on which the lower electrode plate 10 is installed and the lower current-carrying window 4 is placed on the salt-containing water electrical connection body 9 is in close contact with the food container 1. urge A salt-containing water contact body 11 of the same type as the salt-containing water contact body 9 is closely fitted onto the raw food material A filled and housed in the food container 1 so as to close the upper current-carrying window 2. At the same time, the salt-containing water electrical contact body 11 is
The food material A is pressed under equal pressure by the downward pressing action of the upper electrode plate 12 located above it.
The structure is such that raw food material A can be uniformly sterilized by heat sterilization within a short period of time to produce an energized processed food by the energizing action applied between the upper and lower electrode plates 12 and 10. . Reference numeral 13 denotes a temperature detection needle protruding downward from the center of the upper electrode plate 12 for detecting the ripening temperature.

Note that the lower current-carrying window 4 provided on the bottom flat surface 3
Since the energized area of is slightly smaller than the energized area of the upper current-carrying window 2, leaving the window frame 5 of an appropriate shape, the amount of current flowing between the upper and lower electrode plates 12 and 10 is approximately By equalizing, it is possible to reliably prevent the heating sterilization process from becoming uneven due to imbalance in the amount of electricity applied, or the food material A on the lower energizing window 4 side being burnt and the product value being reduced. Forgive me?
Due to the presence of the appropriately shaped window frame 5, the salt-containing water electrical contact body 9
When placed on the outside or inside of the bottom flat surface 3, the raw food material A is maintained in its shape-retaining state.
The close effect between the salt-containing water contact body 9 and the saline water contacting body 9 can be ensured.

Therefore, 10 g of common salt was added to raw food material A consisting of 400 g of sardine surimi material, and the mixture was stirred and mixed, and then the raw food material A was filled and housed in food container 1. After that, the food container 1 is
Lower electrode plate 10 on which the salt-containing water electrical connection body 9 is placed
is housed in an insulating storage frame 8 fitted into the bottom side, and the raw food material A and the salt-containing water contact body 9 are evenly brought into close contact with each other through the lower current-carrying window 4. Next, a salt-containing water electrical connection body 11 is placed closely from the upper surface side of the filled raw food material A, that is, from the upper current-carrying window 2 side,
Furthermore, apply the upper electrode plate 12 from the outside,
The upper electrode plate 12 is pressurized. Then, due to the pressurizing action, the raw food material A is brought into close contact with the upper and lower saline water contact bodies 11 and 9 via the upper and lower current-carrying windows 2 and 4. Therefore, if electricity is applied across the upper and lower electrode plates 12 and 10, the current will flow evenly and the ripening temperature will reach 90 degrees in about 3 minutes, making raw food material A into an energized processed food with good flavor. Perhaps because of this, there was no burnt part on the food material A in the four parts of the lower current-carrying window due to the absence of unbalanced energization, and it was possible to easily obtain an electrification-processed food with high product value.

Six lower current-carrying windows 4 are provided in FIGS. 1 and 2, but when the food container 1 itself is formed into a rectangular cylindrical shape, the lower current-carrying windows 4 shown in FIGS.
As shown in the figure, the lower current-carrying windows 4 can be provided in three, four, or nine pieces, leaving the window frame 5, and the food container 1 can be provided as shown in Figs. 7 to 9. In the case of a cylindrical shape such as that shown in FIG.

In that case, it goes without saying that the shape of the insulating storage frame 8 is formed into a hollow cylindrical shape so as to match the shape of the food container 1.

Effects of the Invention In short, since the present invention has the above-mentioned technical means and effects, the filled raw food material A can be subjected to heat sterilization in a shorter time than conventional food containers. In order to easily mass-produce flavorful energized processed foods, the energized areas of the upper energized window 2 and the lower energized window 4 are made as equal as possible, and the upper and lower energized windows 2 and 4 are distributed even during short-time processing. In addition to making it possible to substantially equalize the amount of electricity, the raw food material A on the side of the lower current-carrying window 4 can be improved without being rushed, and the product value can be improved.
Even if the lower energizing window 4 is opened wide, the shape of the bottom side of the food container 1 can be accurately maintained, and energized processed foods of a desired shape can be mass-produced at any time.
