Description
この発明は、電子レンジでの炊飯方法に関するもので、容器に土鍋を使用することによって、熱容量が大きい、熱伝導性が低い、遠赤外線を放射する、といった特性を利用して、単純な出力調整で自動炊飯を行うものである。 The present invention relates to a method of cooking rice in a microwave oven. By using a clay pot as a container, simple output adjustment is performed by utilizing characteristics such as large heat capacity, low thermal conductivity, and radiating far infrared rays. This is what cooks rice automatically.
単身者やお年寄世帯、働く母親の増加等、社会構造の変化で炊飯に求められているのは「少量・簡単・安全」である。少量のご飯をおいしく炊く事は、ガスや電気の炊飯器でも炊きムラが生じやすく難しい。 “Small amount, easy, safe” is required for cooking rice due to changes in social structure such as singles, elderly households, and increasing working mothers. It is difficult to cook a small amount of rice deliciously even with gas or electric rice cookers.
電子レンジでおいしく炊飯するためには、水や米の量により異なる温度や湿度の変化をセンサーで測定して出力を微妙に調整する必要があり、プログラムが複雑になり商品化が難しかった。(特許文献1)(特許文献2) In order to cook deliciously in a microwave oven, it was necessary to measure changes in temperature and humidity that differ depending on the amount of water and rice with a sensor and finely adjust the output, making the program complicated and difficult to commercialize. (Patent Document 1) (Patent Document 2)
少量の暖かいご飯が火を使わないで短時間で出来るという点で、電子レンジで温めるパックご飯は便利で、需要が高まっているが、プラスチックゴミの増加が心配される。また、陶器製で一膳分の炊飯を電子レンジでする商品は、茶碗型の形状により熱対流が起こりにくく炊きむらの生ずる難点があり、また、出力:弱のみで炊飯するため一膳分より多く炊飯するのは難しい。
従来、電子レンジでおいしく炊飯するためには、米や水の量により異なる温度や湿度の変化をセンサーで測定して出力を微妙に調整する必要があり、プログラムが複雑になり商品化が難しかった。 Traditionally, in order to cook deliciously in a microwave oven, it was necessary to finely adjust the output by measuring changes in temperature and humidity that differ depending on the amount of rice and water with a sensor, making the program complicated and difficult to commercialize .
本発明は、電子レンジでの炊飯において、熱容量が大きい、熱伝導性が低い、遠赤外線を放射する、といった特性をもつ土鍋を容器に使用し、沸騰までの時間を、加熱開始から10分〜20分の間にする事で、おいしいご飯を炊き上げることができるようにしたものである。 The present invention uses a clay pot having characteristics such as large heat capacity, low thermal conductivity, and radiating far infrared rays for cooking in a microwave oven, and the time to boiling is 10 minutes from the start of heating. In 20 minutes, you can cook delicious rice.
この炊飯方法によれば、決められた量の洗った(無洗米ならそのまま)米と水を土鍋に入れて、電子レンジで加熱すれば、短時間で、芯も、炊きムラも無いおいしいご飯が炊き上がる。 According to this rice cooking method, if you put a predetermined amount of washed rice (if it is unwashed rice) and water into a clay pot and heat it in a microwave oven, you can get delicious rice without core and cooking unevenness in a short time. Cook up.
米の体積に対する水の量は1.3倍、無洗米の場合は普通米を洗っている間に吸水される分として1割増しの1.4倍を標準とする。 The amount of water with respect to the volume of rice is 1.3 times, and in the case of non-washed rice, the amount of water absorbed while washing ordinary rice is increased by 10%, which is 1.4 times the standard.
土鍋の形状は、沸騰時に蓋の穴からの噴出物の流出を防ぐために、縁が高く蓋が中に納まるものが望ましい。また、熱対流を速やかにするために底は平らな面があり丸みを帯びたものが良い。 The shape of the earthenware pan is desirable to have a high edge and a lid inside to prevent outflow of ejecta from the hole in the lid when boiling. Moreover, in order to make thermal convection quick, the bottom should have a flat surface and be rounded.
浸漬時間は5分程度で加熱を開始することができる。 Heating can be started with an immersion time of about 5 minutes.
加熱は出力:弱の第1段階、出力:強の第2段階と出力:弱の第3段階に分ける。時間配分は、米と水の量、気温や水の温度、土鍋の大きさによって変わる。第1段階の出力:弱での加熱で電子レンジのマイクロ波と水温上昇により浸漬は促進されるが、土鍋の特性である、熱容量が大きく熱伝導性が低い事により水温上昇は緩慢になり、米粒内部まで水分を行き渡らせる事ができる。芯の無いご飯を炊くためには、十分な浸漬のほかに、加熱時間が早過ぎないことも大切である。短時間で高温になると、米粒表面の糊化が先に進み、内部の糊化を妨げることになる。よく浸漬された米でも芯のあるご飯ができるのは、このケースであり、少ない量の米をおいしく炊くのが難しいのは、この点にある。第2段階の出力:強は、沸騰までの時間を適度に早めるためのものである。第1段階の出力:弱と第2段階の出力:強で、「始めちょろちょろ、中ぱっぱ」の、炊飯に理想的な加熱となる。出力:強で沸騰させると沸騰が激しくなるので、第3段階の出力:弱で沸騰するように調整する。 Heating is divided into output: weak first stage, output: strong second stage and output: weak third stage. The time distribution varies depending on the amount of rice and water, the temperature and temperature, and the size of the clay pot. The output of the first stage: Dipping is promoted by microwave heating and water temperature rise by weak heating, but the water temperature rise slows due to the characteristic of clay pot, large heat capacity and low thermal conductivity, Moisture can be spread to the inside of the rice grain. In addition to sufficient soaking, it is important that the heating time is not too early for cooking rice without a core. When the temperature rises in a short time, the gelatinization of the surface of the rice grains proceeds and the internal gelatinization is hindered. This is the case where well-soaked rice can produce core rice, and this is why it is difficult to cook small amounts of rice deliciously. The output of the second stage: Strong is to moderately accelerate the time to boiling. The output of the first stage: weak and the output of the second stage: strong. Output: Since boiling is intense when boiling is strong, adjust the output of the third stage: boiling at low.
蒸らしの間も、温められた土鍋から遠赤外線が放射される事と、熱容量が大きい事とにより、じっくりと芯まで蒸らされて、ふっくらとしたご飯に炊き上がる。 During steaming, far infrared rays are emitted from the warmed earthenware pot and the heat capacity is large, so it is steamed to the core and cooked into plump rice.
気温25℃では、6号土鍋(0.8リットル・1〜2人用)を使用し、米200ccを、200W→500W→200Wを2分→5分→10分で制御して、茶碗二膳分が、おいしく炊けた。気温が低い場合は、加熱前の浸漬段階で水温を20℃まで上げる、500Wでの加熱時間を延ばして所定の温度まで上げる、という方法でおいしく炊けた。 At a temperature of 25 ° C, use a No. 6 clay pot (0.8 liters for 1 to 2 people) and control 200cc of rice from 200W → 500W → 200W in 2 minutes → 5 minutes → 10 minutes. I cooked it deliciously. When the temperature was low, the water temperature was raised to 20 ° C. in the soaking stage before heating, and the cooking time was increased to a predetermined temperature by extending the heating time at 500 W.
同様に、気温25℃では、深型6号土鍋(1.6リットル)、7号土鍋(1.0リットル・2〜3人用)を使用し、実施例1の米200ccの他に、米300ccが200W→500W→200Wを2分→8分→7分で制御して茶碗三膳分がおいしく炊けた。米400ccの場合、200W→500W→200Wを2分→11分→4分の制御で、茶碗四膳分がおいしく炊けた。米の量は±20cc程度まで同じ時間制御で炊く事ができた。従って、米180cc〜420ccまでなら、「加熱」の第2段階は500Wで炊飯可能である。米450cc以上を炊く場合は第3段階の出力:強を600W以上に設定する。 Similarly, at a temperature of 25 ° C, deep type 6 earthenware pots (1.6 liters) and No. 7 earthenware pots (1.0 liters for 2 to 3 people) are used. 500W → 200W was controlled in 2 minutes → 8 minutes → 7 minutes, and the tea bowls were deliciously cooked. In the case of 400cc rice, the tea bowls were cooked deliciously by controlling 200W → 500W → 200W for 2 minutes → 11 minutes → 4 minutes. The amount of rice could be cooked under the same time control to about ± 20cc. Therefore, if it is from 180cc to 420cc of rice, the second stage of "heating" can be cooked at 500W. When cooking more than 450cc of rice, set the output of the third stage: strength to 600W or more.
一人暮し用の電子レンジに、200cc用のプログラムを付ければ、茶碗二膳分が簡単に炊ける。二膳目は土鍋のまま再加熱でき、少ないご飯を保温する必要はなくなる。狭い台所で炊飯器のスペースが要らなくなる。 If you attach a 200cc program to a single-use microwave, you can easily cook a bowl of teacups. The second pot can be reheated in a clay pot, eliminating the need to keep a small amount of rice warm. Eliminates the need for a rice cooker space in a small kitchen.
一般の家庭用の電子レンジに、200cc、300cc、400cc用のプログラムを付けても、それ程コストはかからない。お年寄世帯や、働く母親を待っている子供でも、火を使わないから安全にご飯を炊く事が出来る。 Adding a 200cc, 300cc, or 400cc program to a general household microwave oven does not cost much. Even elderly households and children waiting for working mothers can cook rice safely without using fire.
一回分に分包された米や対応した水の計量カップがあれば、細かい字や目盛りが読みにくいお年寄や、数字が読めない子供にとってもさらに便利である。一回分にした米に対応した量の「合わせ酢」の小さなパックがあれば、鮨飯も手軽に作ることもできる。土鍋に、米に対する水の量を提示する線をつけたものも、水の計量の手間を省くのに役立つ。 If you have a measuring cup of rice and water that is packaged in a single dose, it will be even more convenient for elderly people who have difficulty reading small letters and scales, and for children who cannot read numbers. If you have a small pack of “matched vinegar” that corresponds to the amount of rice in a single batch, you can easily make rice. A clay pot with a line that shows the amount of water relative to the rice also helps to save water.
