。<Conventional technology> Conventional microwave ovens cook by utilizing the property that the irradiated microwaves are absorbed by molecules such as water contained in the food to be cooked, and the food is directly heated. Generally, it has the advantage that it can be prepared in a short time. On the other hand,
Unlike direct flame cooking methods such as ovens, gas ranges, resistance heaters, and charcoal grills, it is not possible to scorch the surface of the food, which has the drawback of severely limiting the types of food that can be cooked.

For example, a microwave oven with an oven mechanism that can heat the food with microwaves without burning the surface of the food by installing a heating element such as an electric heater with a cut circuit in the microwave oven, a so-called microwave oven or a commercially available microwave oven. has been done. However, the structure is complicated and cannot be made smaller.
There are problems such as significantly increased power consumption, longer cooking times, and higher prices.

Heating elements and containers have been devised that can improve the

However, when mixed with food, the microwaves are absorbed by the food, and the amount of energy absorbed by the heating element is reduced. The disadvantage is that it is limited to foods with low yields.

になり、はとんどすべてのエネルギーが発熱体に吸収さ
れ、発熱体単独の時と同程度の発熱をすることになる。Effect> The present invention suppresses the absorption of microwaves into food emitted from a microwave oven, so that the heating element preferentially absorbs the microwaves and generates heat, causing the heating element itself to rapidly heat to a high temperature. There is a need for a device that enables oven or grill cooking, such as browning the food by the conductive heat and radiant heat of the heating element. A method to suppress absorption into food is to shield part or the entire surface of the food from incoming microwaves using an electromagnetic wave reflecting material such as a metal plate, box surface, or net-like structure. can. The way it is absorbed into food can be adjusted by the way it is shielded. If it is completely sealed with reflective material, the absorption rate will be zero, and almost all of the energy will be absorbed by the heating element, which will generate the same amount of heat as when the heating element alone.
よって、遮蔽のし方を調整することで発熱体と食品への
吸収度をコントロールし、適切な調理を可能にする。Therefore, by adjusting the shielding method, the degree of absorption into the heating element and food can be controlled, allowing appropriate cooking.
反射材のかわりに電磁波吸収体を用いることもできる。An electromagnetic wave absorber can also be used instead of a reflective material.
その場合、発熱体も電磁波吸収体の一種であるが、食品
への入射を抑制するためであることから吸収率の高いも
のよりは低い方が望ましい。例えば、ＳｉＣ、チタン酸
バリウム等が好ましく、これらを箔、板、網あるいは被
覆の形で用いる。In this case, the heating element is also a type of electromagnetic wave absorber, but since the purpose is to suppress the incidence of electromagnetic waves into the food, it is preferable that the heating element has a low absorption rate rather than one with a high absorption rate. For example, SiC, barium titanate, etc. are preferred, and these are used in the form of foil, plate, net, or coating.
反射材では、はぼ完全に入射マイクロ波を遮断するが、
吸収材では一部は吸収（＝発熱〉され、一部は反射され
、残りは透過して食品に吸収されることになる。調理食
品によっては、反射材を用いて食品へほとんど吸収され
ないようにするのが望ましいものや、吸収体を用いて食
品へある程度吸収されたほうが適切な調理ができるもの
などがある。Reflective materials almost completely block incident microwaves, but
With the absorbent material, some of the heat is absorbed (= generates heat), some of it is reflected, and the rest is transmitted and absorbed by the food. Depending on the food being prepared, reflective materials are used to prevent most of the heat from being absorbed by the food. There are some foods that it is desirable to absorb into the food, and some foods that can be cooked more appropriately if they are absorbed to some extent into the food using an absorbent material.
反射材あるいは吸収体の選定、ざらには遮蔽度の調整に
よリバランスをとることであらゆる調理が可能になる。By selecting reflective materials or absorbing materials, and adjusting the degree of shielding, you can achieve any kind of cooking.
一方、他の抑制方法として、食品を冷凍処理して抑制す
る方法かある。水と氷とては、その電気的性質が異なる
ことから、マイクロ波の吸収率は水の方が約３，６００
倍も高い。On the other hand, another method of suppressing this is to freeze the food. Water and ice have different electrical properties, so water has a higher microwave absorption rate of about 3,600
It's twice as expensive.
そこで食品中の水分を冷凍処理することによって凍らせ
、食品のマイクロ波吸収率を低下させ、発熱体により多
くのエネルギーを吸収させ高温に発熱させるものでおる
。発熱体の発熱により、氷が溶解し、それとともに食品
への吸収率が高くなり、マイクロ波による加熱がなされ
、短時間調理か可能になる。発熱体は初期段階で高温に
なっているため、食品を焦がすなどのオーブン調理をす
るだけのエネルギーは十分に有する。Therefore, the moisture in the food is frozen by freezing, which lowers the microwave absorption rate of the food and causes the heating element to absorb more energy and generate heat to a high temperature. The heat generated by the heating element melts the ice, which increases the absorption rate of the food and allows it to be heated by microwaves, making it possible to cook food in a short time. Since the heating element is at a high temperature in the initial stage, it has enough energy to perform oven cooking such as browning food.
使用する発熱体としてはフェライト、ＳｉＣなとの焼結

熱物質をコーティングしたものなど幅広く選択すること
ができる。The heating element to be used can be selected from a wide range of materials, including sintered bodies of ferrite and SiC, porcelain incorporating these, and heat-resistant base materials coated with heating substances.
シールド材として金属を使用する場合、端部あるいはタ
ーンテーブル、内壁などの接触部がスパークする危険が
あるため、ガラスあるいは無機被膜等を施し、電界が集
中しないようにすることが望ましい。If metal is used as the shielding material, there is a risk of sparks occurring at the ends or contact areas such as the turntable or inner wall, so it is desirable to apply glass or an inorganic coating to prevent electric field concentration.

りがただよい、良好な風味を有した。By the way, as in the structure shown in Figure 1, a pillow is placed on top of the heating element, and a shield box attached to a container made of polypropylene with AfJ foil as a shielding material is placed on top of it so that it does not come into contact with the heating element. I cooked it in the microwave. The heating element used was Q, a 5mm thick iron plate coated with Fe3O4 powder with an inorganic binder to a thickness of 300μm.
It was produced by baking at 0°C-3C-3O. the result,
Without the shield box, there was almost no browning, but with the shield box, the entire surface of the kraft had a light golden brown color, and had a good flavor with a crisp texture and a pleasant aroma.
