Abstract

To savorily cook rice using a microwave oven, it is required in the conventional technology to measure changes in temperature and humidity, which vary depending on the amount of rice or water, and delicately control the output. Thus, a complicated program is needed, which makes it difficult to commercialize such a product. Under these circumstances, it is intended to savorily cook rice using a microwave oven by using as a container an earthen pot, which is characterized by having a large heat capacity and a low heat conductivity and radiating far-infrared rays, and controlling the time from the start of heating to boiling to 10 minutes to 20 minutes.

Description

Microwave oven with automatic rice cooking mode {Microwave oven having automatic rice cooking mode}

The present invention is characterized by high heat capacity, low thermal conductivity, and far-infrared radiation as a container when cooking rice containing 80% by weight or more of non-rice of japonica species or rinse-free rice with a microwave oven. The present invention relates to a microwave oven with an automatic cooking mode including a program capable of performing automatic cooking by simple output adjustment by using a vaginal pot having a.

The key point required for cooking due to changes in the social structure, such as the increase of singles, elderly generations, and mothers with jobs, is "small amount, simple, and safe." However, cooking a small amount of rice is difficult to cook rice even if you use a gas or electric rice cooker.

In order to cook deliciously with a microwave oven, in the prior art, it was necessary to precisely adjust the output by measuring a change in temperature or humidity depending on the amount of water or rice. Therefore, the program was complicated and commercialization was difficult (refer patent document 1 and patent document 2).

Although a small amount of rice can be cooked in a short time without using fire, packaged instant rice, which is heated in a microwave oven, is convenient and is increasing in demand, but there is concern about an increase in plastic waste generated from these products. In addition, products using a microwave oven for cooking with one air of porcelain are difficult to produce tropical currents and easy to cook due to the shape of the ceramic, and also have to be cooked with low power. It's hard to cook rice.

[Initiation of invention]

[Problems that the invention tries to solve]

Conventionally, in order to cook rice that contains 80% by weight or more of japonica varieties of non-glutinous rice in a microwave or deliciously, it is necessary to precisely adjust the output by measuring a change in temperature or humidity depending on the amount of water or rice. In addition, the program was complicated, making it difficult to commercialize.

[Means for solving the problem]

In the present invention, when cooking rice containing 80% by weight or more of non-rice rice of japonica species, or no rice, in a microwave oven, using a vaginal pot as a container, automatically cooking rice finely and soaking for 5 minutes or more A rice is heated for 2 to 5 minutes with the output of the microwave at low, and the output steel is then adjusted with the output at about time, so that the vaginal pot boils between 10 and 20 minutes from the start of heating. It relates to a microwave oven with an automatic rice cooker mode unit including a program.

[Effects of the Invention]

According to the microwave oven of the present invention, when a predetermined amount of washed (as long as it is no matter) rice and water are put in a vaginal pot and the microwave oven is switched on, the heating output is automatically controlled and there is no core in a short time. Delicious rice is cooked.

1 is a flow chart of the present invention.

Best Mode for Carrying Out the Invention

The amount of water in the volume of rice is 1.3 times, and in the case of non-semi rice, 1.4 times, which is 10% more than that of ordinary rice, due to the amount of water absorbed during washing.

The shape of the vaginal pan preferably has a higher edge than the lid so that the lid and the lid enter the vaginal pan. In addition, the bottom of the vaginal pan should be flat and rounded.

The rice is soaked for about 5 minutes before it is heated.

The heating is divided into output: first step of drug, second intermediate step, and third step of drug. The time allocation at each stage varies with the amount of rice and water, the temperature or temperature of the water, and the size of the vaginal pot.

During heating in the first step-heating output: Immersion is facilitated by microwave and water temperature rise of the microwave oven. Due to the high heat capacity and low thermal conductivity of the quality pot, the rise in water temperature is slow and it can spread the water to the inside of the rice grains. In order to cook rice without a core, it is important to cook slowly in addition to sufficient soaking. When the rice becomes hot in a short time, gelatinization of the surface of the rice grains proceeds first, which interferes with the gelatinization of the rice grains. In this case it is difficult to make a small amount of rice deliciously in this case, even in well-soaked rice is a cored rice.

Second Step-Heating Output: The steel is intended to facilitate the time until the vaginal pot boils. The combination of the first stage-heating output: weak and the second stage-heating output: steel provides an application of ideal heating for cooking, such as "first heating is weak, medium heating is strong".

Because of this fact, boiling to Power: Rough causes severe boiling, so adjust to the third stage of Power: Bow.

After heating, the rice is steamed (ie post-cooking rest). During steaming, the rice is steamed far from the heated vaginal pan to the far-infrared radiation and heat capacity, so that the rice is steamed and cooked.

If the temperature is low, a temperature sensor is used to extend the heating time at 500W.

Example 1

Using a No. 6 vaginal pot (0.8 liters for one or two persons) at a temperature of 25 ° C, 200cc of rice is cooked under heating control of 260cc of water, 200W → 500W → 200W from 2 minutes → 5 minutes → 10 minutes. The final amount of 2 air (approximately 600 cc) of rice was cooked deliciously (here we use a standard sized bowl of 340 cc in volume). In the case of low temperatures, the heating time at 500W was extended to make it delicious.

Example 2

Similarly, using a deep type No. 6 vaginal pot (1.6 liters) and No. 7 vaginal pot (1 liter for 2 to 3 persons) at a temperature of 25 ° C., 300 cc of rice were 200W → 500W in addition to 200cc of the rice of Example 1 → 200 W was heated for 2 minutes → 8 minutes → 7 minutes, and the final amount of the 3 air of rice was cooked deliciously. In the case of 400cc of rice, heating from 200W to 500W to 200W was controlled from 2 minutes to 11 minutes to 4 minutes, so that 4 air amounts of rice were cooked deliciously. The amount of rice could be cooked with the same heating time control up to approximately ± 20 cc. Therefore, in the case of up to 180cc to 420cc of rice, the second stage of the heating output can be cooked at 500W. If the rice is 450cc or more, set the output of the third stage: steel to 600W or more. In Examples 1 and 2, microwave ovens are vaginal pots No. 6 and No. 7 sold under the trade names Sharp RE-WB30, Kinpo Seito / Hanamishima, and Ishigaki Sangyo. A combination of Shim No. 6 vaginal pot, 100% of Hatsushimo rice, 100% of Koshihikari Musemi, 95% of Hatsushimo, and 5% of glutinous rice, sold under the Ryokusen brand name, was used.

TABLE 1

Example at 25 ° C Degree Amount of rice 200cc 300cc 400cc 200W 2 minutes 2 minutes 2 minutes ↓ ↓ ↓ ↓ 500W 5 minutes 8 minutes 11 minutes ↓ ↓ ↓ ↓ 200W 10 minutes 7 minutes 4 minutes point Immersion (5 minutes) ↓ Heating (17 minutes) ↓ Steaming (13 minutes) Can be heated after 5 minutes of immersion time. Immersion is promoted by microwave heating. • Due to the large heat capacity of the vaginal pot and low thermal conductivity, the temperature rises slowly, and there is no fear that the surface of the rice grains will be gelatinized first and become a cored rice. It is preferable to boil about 15 minutes from a heating start. Boil it over low heat to prevent it from boiling too hard. · The rice is steamed by the effect of far infrared rays. When the temperature is low, the temperature sensor is used to extend the time of 500 W heating until the predetermined temperature is reached.

If you install a program for 200cc in a microwave for single life, you can easily build 2 bowls of rice. The rest of the rice (e.g. rice in the second air) can be reheated in an unremoved vaginal pot and the need for warming less rice, as is done in an electronic cooker, eliminates the need for Space becomes unnecessary.

Even if you install a program for 200cc, 300cc, 400cc in a microwave oven for home, it doesn't cost much. Older generations and children waiting for mothers who have a job can safely cook because they do not use fire.

If you have rice or measuring cups packed in one air or one serving of rice, it is more convenient for older people who cannot read small letters or scales or children who cannot read numbers. The amount of rice in one air is about 90cc with less rice and about 120cc with big rice. If you have a small pack of ready-mixed vinegar for a serving of rice, you can easily make sushi rice. Vaginal pots that draw the amount of water relative to the amount of rice also help to weigh the water.
