Description
- 122562~
l This invention relates to a foodstuff con-tainer for electrical processing of the foodstuff, wherein the foodstuff container of any shape as desired formed at its flat bottom with a multiplicity of current passing apertures is readily and simply filled with unprocessed foodstuff, such as meat, fish, grains or vegetables or a mixture thereof or any other foodstuff or any suitable fixing medium, impregnated with a dilute salt solution, either having a suitable seasonings and/or spices incorporated therein or not, so that a delicious packed processed food can be produced anytime by passing a current through the foodstuff to ripen and sterilize same by heat.
Heretofore, a proposal has been made by us to provide a packed food by filling a packing bag with a sealed charge of unprocessed foodstuff, such as meat, fish, grains or vegetables or a mixture thereof or any other foodstuff or a suitable fixing medium, impregnated with a dilute salt solution, either having suitable seasonings and/or spices incorporated therein or not, and passing a current through the charge of foodstuff and the container to thereby ripen and sterilize the foodstuff by heat to produce a packed processed food.
When a packed processed food is produced by ~22~i62~
1 this method, unprocessed foodstuff is placed in a packing bag which is formed of heat resisting and insu-lating material soft and pliable and open at opposite ends. When a charge of unprocessed foodstuff is fil~ed in the bag, it is necessary that one open end of the bag be first tied up or otherwise closed and then the desired foodstuff be filled in the bag through the other open end, the other open end being sealed after the foodstuff is filled in the bag. This packing operation is troublesome and time-consuming. When a large number of packed foods are to be produced, it is impossible to carry out the operation efficiently in a short period of time. In adition, the packing bag is very thin and soft, and the open ends thereof become sticky when wet by foodstuff charging operation, thereby making it dif-fucult to readily open the ends. When such situation occurs, difficulty is experienced in filling the packing bag with a charge of unprocessed foodstuff in a prede-termined volume, thereby making it difficult to perform foodstuff charging efficiently. In other words, the method has been found to be unsuitable for mass produc-tion of packed foods.
;~ This invention has been developed for the pur-pose of obviating the aforesaid problem of the prior art. Accordingly the invention has as its object the `~ provision of a foodstuff container capable of producing ~ a packed food readily merely by passing a current ~ ' ,. . .

A preferred embodiment of the invention will now be described by rferring to the accompanying drawings.
Referring to Fig. 1, the numeral 1 designates a foodstuff container allowing suitable foodstuff A, such as meat, fish, grains or vegetables or a mixture thereof or any other foodstuff or suitable fixing medium, impregnated with a dilute salt solution, either having suitable seasonings and/or spices incorporated therein or not. The foodstuff container 1 is formed of heat resisting and insulating material and open at the top and has a flat bottom 2 formed with a multilicity of current passing apertures 3. As shown, the foodstuff , .
container 1 is cylindrical in cross section, but the invention is not limited to this specific shape of the foodstuff container 1. The foodstuff container 1 of the aforesaid construction is formed integrally at the periphery of its upper open end with a flange 4 which ... .....
lZ~6Z~
1 extends horizontally. The foodstuff container 1 may be rectangular (square) as shown in Figs. 2 and 3 or triangular as shown in Fig. 4 in cross section. The current passing apertures 3 formed at the bottom 2 of the foodstuff container 1 of any shape as desired have a size such that they do not allow leaks of the foodstuff from the container to outside. In Figs. 1-3, the current passing apertures 3 are shown as being circular.
However, the invention is not limited to this specific shape of the apertures 3 and they may be in mesh form as indicated at 3' in Fig. 4.
The numeral 5 designates an apparatus for pro-ducing a packed foodstuff A by using the aforesaid foodstuff container 1, which comprises a hollow cylindrical insulating container 6 open at the top and the bottom, a salt solution impregnated electrical con-; tact member 7 formed of fibrous material impregnated with a salt solution, and an electrode plate 8 sup-porting the salt solution impregnated electrical contact member 7 thereon and supported on a flange 10 on the bottom side of a hollow cylindrical portion 9 of the insulating container 6. The foodstuff container 1 is inserted in the insulating container 6 in such a manner that the flat bottom 2 formed with the current passing apertures 3 is in intimate contact with the salt solu-tion impregnated electrical contact member 7. The operation efficiency could be improved by tapering the ~Z2S62~
1 hollow cylindrical portion 9 of the insulating container 6 to facilitate the insertion and withdrawing of the ffoodstuff container 1 with respect to the insulating container 6 and the elevatory movement of the electrode S plate 8. A salt solution impregnated electrical contact member 11 of the same type as the salt solution impregnated electrical contact member 7 is placed on the foodstuff A filled in the foodstuff container 1, and another electrode plate 12 is brought into pressing engagement with salt solution impregnated electrical contact member 11, to apply uniform pressure to the foodstuff A. By passing a current between the two electrode plates 8 and 12, it is possible to ripen and sterilize the foodstuff A by the Joule heat in a short period of time to provide a processed food B, The numeral 13 designates a packing film provided at the upper open end of the foodstuff container 1 enabling the processed food B to be preserved over a prolonged period of time. The packing film 13 is secured by suitable means, such as melt adhesion, to the flange 4 of the foodstuff container 1.
By further arranging a salt solution impregnated electrical contact member 14 inwardly of the .
flat bottom 2 of the foodstuff container 1 as indicated by a broken line in Figs. 5 and 6 before the foodstuff A
is filled in the container 1, it is possible to achieve better results in ripening and sterilizing the foodstuff 1~25621 1 A by passing a current therethrough.
In operation, the suitable foodstuff A can be filled in the foodstuff container 1 readily and quickly without requiring any s~ills by inserting same through the upper end of the container 1 shown in Fig. l. After a predetermined volume of foodstuff A is filled in the foodstuff container 1, the foodstuff container 1 is inserted in the insulating container 6 in such a manner that the container 1 is placed on the salt solution impregnated electrical contact member 7 supported on the bottom side of the hollow cylindrical portion 9 of the container 6, and the salt solution impregnated electri-cal contact member 11 is placed on the foodstuff A on the open end of the container 6. Then the electrode plate 12 is prssed downwardly.
Thus the salt solution impregnated electrical contact members 7 and 11 interposed between the pair of : upper and lower electrode plates 8 and 12 are brought into intimate contact with each other, either directly or through the current passing apertures 3. By passing a current between the two electrode plates 8 and 12, the current flows accurately through the foodstuff A in uni-form condition, and the foodstuff A is ripened and :~ sterilized in a short period of time by the heat of resistance or Joule heat, to provide the processed food B. When the foodstuff A is processed into the processed food B, the foodstuff container 1 is removed from the ~ 7 -:::
.
~2~
1 insulating container 6 and has its open end covered with the packing film 13. This enables the processed food B
to be packed and preserved over a prolonged perlod of time in hygenic condition. When it :i5 desired to fully seal the processed food B, the processed food B may be also covered at its bottom side or the current passing apertures 3 side with a sheet of film of suitable material.
From the foregoing description, it will be appreciated that the foodstuff container 1 according to the invention which is of any shape as desired and formed of heat rsisting and insulating material has an open end and a 1at bottom 2 ~ormed with a multiplicity of current passing apertures 3 for receiving a charge of unprocessed foodstuff A therein. Thus the invention enables the foodstuff A as it is filled in the foodstuff container 1 to be ripened and sterilized by heat in a short period of time as a current is passed therethrough, to provide a delicious packed ~ood.
Filling the foodstuff container 1 with a charge of food-stuff requires no skills, so that the operation can be preformed efficiently and the production of packed foods can be carrled out on a mass production basis.
Moreover, by placinq a salt solution impregnated electrical contact member on the foodstuff A filled in each foodstuff container 1 of a large number of foodstuff containers 1 each filled with the foodstuff A, ,..
1.. ! -- 8 1225~i21 1 mass production of the packed foods is facilitated. If the foodstuff containers 1 in this condition are stored in refrigerating apparatus, it is possible to pass a current therethrough anytime as desired. The foodstuff containers 1 can be placed one over another, so that they can be stored in any place as desired without requiring a large space. The foodstuff container 1 can be formed in small thickness without impairing integrity, thereby contributing to reduced cost of production.
