Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention uses a Joule heat generated by an energizing action of a food material composed of, for example, white rice, wheat or other grains, etc., which is directly passed through the food material in a vertical direction. The present invention relates to an electric current processing method for foods that can be processed in a short time while saving electricity and can be served as a delicious electric processed food having a flavor and a different chewy texture.

[Prior Art] Conventionally, a method of cooking rice by arranging a pair of electrodes on the bottom or inner surface of a rice cooking container to generate electricity to generate steam is well known.

[Problems to be Solved by the Invention] By the way, in the conventional processing method, there is a problem in that the electrode is arranged on the bottom or side surface of the container, and the boiling water mainly generated on the bottom side cannot be effectively raised. .

[Means for Solving the Problems] The present invention is to solve the above problems, and the method thereof will be described below with reference to FIGS. 1 and 2 corresponding to the embodiments.

That is, the lower electrode 102 having a large number of air passage windows 103 is arranged on the inner bottom surface of the bottomed insulating container 101 having a cylindrical shape.
Next, a bubble chamber 107 is provided on the lower electrode 102 to generate bubbles by the action of electricity. An appropriate amount of food material A is accommodated in the upper part of the bubble chamber 107 together with the conductive liquid B, and an upper electrode 108 having a large number of air passage windows 109 is freely placed on the food material A in the bottomed insulating container 101. This is an electric current processing method in which food is subjected to electric current processing by applying an electric current between the pair of electrodes 102 and 108 after arranging so as to be able to move up and down so as to face the lower electrode 102.

[Function] For example, in order to easily obtain an electrically processed food which can process, for example, white rice, wheat or other food material A in a short time by an electric operation, a cylindrical bottomed insulating container 101 having an open upper surface. On the inner bottom flat surface of, the lower electrode 102 having a large number of bubble passage windows 103 is arranged, and then a cage 104 having a large number of bubble ejection holes 105 is arranged above the lower electrode 102,
A bubble chamber 107 is formed between the lower electrode 102 and the cage 104. Next, for example, white rice or wheat or other food material A is stored in the bottomed insulating container 101 above the bubble chamber 107 together with the conductive liquid B, and then a large number of air-permeable windows are formed on the surface above the food material A. An upper electrode 108, which has a bottom 109 and is freely moved up and down in the bottomed insulating container 101, is housed under a flooded state and is positioned to face the lower electrode 102. Therefore, by energizing the whole food material A along the vertical direction between the lower electrode 102 and the upper electrode 108, the boiling water from the lower electrode 102 is temporarily stored in the bubble chamber 107 due to the Joule heat generated as the current gradually increases. After passing through a large number of air bubble ejection holes 105, ..., it is ejected and rises into the food material A on average, and boiling water evaporates.
Since it passes through a large number of ventilation windows 109, the upper electrode 108 is prevented from being pushed up by the force of boiling water. In this way, the convective stirring action of the food material A is carried out in the conductive liquid B between the upper and lower electrodes 102, 108, and the temperature is raised. At the same time, the food material A swells gradually, and the upper electrode 108 continues to move while sequentially moving upward. If such a state is continued for a while, the bubble chamber 10
The water content of 7 also gradually evaporates and decreases, and by the time the energization amount decreases, an electrically processed food product in which the entire food material A is energized on average is obtained.

[Example] An example of a manufacturing apparatus for carrying out the method of the present invention will be described with reference to the drawings.

In the drawing, reference numeral 101 denotes a cylindrical bottomed insulating container having an open top surface, and the material thereof may be an insulating waterproof paper material or any other material. 102 is a lower electrode arranged on the bottom flat surface of the bottomed insulating container 101, the lower electrode 102,
A large number of bubble passing chambers 103 having a square shape are formed on the surface thereof. 104 is a cage made of an insulating material disposed in a bottomed insulating container 101 slightly above the lower electrode 102, and a large number of bubble ejection holes 105 are formed on the surface of the cage 104 and the cage 104 The four-sided peripheral edge 106 is bent downward. 107 is a bubble chamber formed between the lower electrode 102 and the cage 104. A is a food material contained in the bottomed insulating container 101 on the cage 104 together with the conductive liquid B, for example, dilute salt water. The food material A is, for example, white rice,
Alternatively, it may be wheat or other cereals or noodles, but the kind is not particularly limited. The amount of the conductive liquid B stored together with the food material A was about 20% higher than that of the food material A, and the diluted salt water containing about 0.5% of the salt content was used. The conductive liquid B may be soup or other liquid food.

Reference numeral 108 denotes an upper electrode that is placed on the food material A housed in the bottomed insulating container 101 so as to face the lower electrode 102. The upper electrode 108 is made of the same material as the lower electrode 102 and is made of a plastic material. A large number of square-shaped air passage windows 109 are formed on the surface of the food material A so that hot air bubbles generated from the food material A can pass upward. The shape of the air passage window 109 is circular or any other shape. The upper electrode 1
08 is a bottomed insulating container 101 that is easily closed by the food material A that has been expanded and softened by the heating of Joule heat generated by the energizing action.
It is possible to ascend and surface along. That is, since the upper end side of the swelling lead wire 111 connected to one end of the upper electrode 108 is extended outward from the upper side of the bottomed insulating container 101, the food contained in the bottomed insulating container 101. Not only can the upper electrode 108 be reliably positioned on the food material A even if the amount of the material A contained is small,
Even when the upper electrode 108 moves upward or downward along the bottomed insulating container 101 due to the bulging of the food material A, or when it descends, the lead wire 111 exhibits flexibility.
It is configured to expand and contract freely. 112 is the lower electrode 1
The waterproof lead wire has one end connected to 02, and the upper end side of the lead wire 112 is extended outward from the upper side of the bottomed insulating container 101. Reference numeral 113 denotes a lid which is detachably covered on the upper open side of the bottomed insulating container 101. 114 is the food material A and the conductive liquid B housed in the bottomed insulating container 101.
It is a vapor storage chamber formed between the lid 113 and the lid 113, and the vapor generated by the boiling water action by energization is stored in the vapor storage chamber 114. Reference numeral 115 is a steam ejection port opened at an appropriate position of the lid 113.

Therefore, according to the method of the present invention, 200 g of the conductive liquid B consisting of 200 g of the white rice food material A that has been washed with water and 200% of dilute salt water having a salt content of 0.5% is stored in the bottomed insulating container 101, and then the bottomed insulating container 101 The upper open side of the is covered with a lid 113.

Then, under the above-mentioned condition, if electricity is applied between the lower electrode 102 and the upper electrode 108 which are vertically opposed to each other, the current flows through the entire food material A, and the temperature is raised by the heating of the generated Joule heat. According to the lower electrode 102, bubbles of boiling water are generated in the bubble chamber 1
It is once accumulated in 07, then passes through a large number of bubble ejection holes 105 and is ejected into the white rice, and the white rice is further heated to the boiling point while being convectively stirred with the conductive liquid B. Therefore, when the energization is further continued as it is, the bubbling water bubbling toward the upper electrode 108 suddenly rises and tries to push up the upper electrode 108, but since a large number of bubble passage windows 109 are opened in the upper electrode 108. , The boiling water bubbling through the air passage window 109,
The upper electrode 108 can be kept in a predetermined position and can continue to be energized to the entire food material A without interrupting the energization with the lower electrode 102. On the other hand, the steam whose pressure has been increased in the steam storage chamber 114 is vigorously ejected from the steam ejection port 115, and the rice grains become swelled. The amount decreases.

Therefore, if the electricity is turned off and steamed for a while, delicious cooked rice that has a good swelling, little stickiness, and a chewy texture will be produced.

It should be noted that, if the other suitable ingredients, seasonings and the like are mixed into the above-mentioned white rice, a delicious mixed rice is completed.

Further, in the present embodiment, the case where only the white rice is used as the food material has been described, but in addition to this, it can be applied to food materials other than cereals and other solid-liquid mixed food materials as well as the bottomed insulating container 101. Shape and lower electrode 102
The shape of the upper electrode 108 and the bubble passage chambers 103 and 109 can be arbitrarily set.

[Effects of the Invention] In summary, the present invention arranges the lower electrode 102 having the through-gas window 103 on the inner bottom surface of the bottomed insulating container 101, and
A bubble chamber 107 is provided above to contain the food material A together with the conductive liquid B, and the bubble passage window 10 is provided on the food material A.
Since the upper electrode 108 having 9 is arranged so as to freely move up and down in the bottomed insulating container 101 and is positioned so as to face the lower electrode 102, even if the food material A is stored in a small amount, the upper electrode 108 Is surely positioned on the food material A, and not only can the entire food material A be energized, but even if boiling water suddenly rises during energization, it will pass through the air bubble window 109 of the upper electrode 108. In addition to preventing the upper electrode 108 from being pushed up, the upper electrode 10 can be pushed in response to the bulging of the food material A.
The 8 also moves up freely, so that it is possible to perform the energization processing surely and quickly by the energizing action applied between the pair of electrodes 102 and 108 from beginning to end.

Further, the lower electrode 102 and the upper electrode 108 are respectively provided with a large number of bubble passage windows 103 and 109, thereby promoting the rising flow distribution effect of the generated boiling water to save power and shorten the processing time, and to make the energization uniform. The effect of being able to achieve the homogenization and always producing a homogeneous electrically processed food.
