JP2006158934A - Manufacturing of inner pan for rice cooker by making full use of characteristic of magnesium alloy - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To manufacture an inner pan for a rice cooker by using a magnesium alloy. <P>SOLUTION: The magnesium alloy has higher electromagnetic shielding effects compared with general plating, on its top, it is excellent in thermal conductivity and can reduce a time required for cooking rice. 4.62 ppm of magnesium (Mg), which can not be generated in a human body, is ionized and impregnated to the boiled rice as one of the characteristics other than mechanical characteristics. Impregnation of magnesium to the boiled rice is a great advantage to contribute to the health of a human body. The magnesium alloy is an optimum metallic material as a material of the inner pan for a rice cooker. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

In the field of electric rice cookers currently used in ordinary households, rice is cooked by a heating method that uses eddy current and hitter, but in the future, it is light, heat-conductive, and shock-resistant among the characteristics of magnesium alloys. New material fields are exploited by utilizing metal properties such as safety and electromagnetic wave absorption.
[Background technology]

The characteristics of magnesium alloys have been known for a long time, but there are difficulties in workability and their use has been limited. However, in recent years, new alloy technologies have been born and the processing technology has been improved. It has been used in various fields in terms of strength, lightness, processability, and magnetic shielding, and the fields of use such as mobile phones, cameras, cars, and PC cases are expanding.
This characteristic shows that minerals (magnesium) that cannot be generated by the human body during rice cooking are ionized and impregnated into the cooked rice (effects to prevent stiff shoulders and arteriosclerosis). This became the background.

The effect of this improvement is that it contains a lot of minerals not found in conventional rice cooking while leaving the method of cooking rice, and that effect is worth improving as it seeks the benefits that promote the health of the human body.
[Disclosure of the Invention]
[Problems to be solved by the invention]

The traditional rice cooker is how to cook rice deliciously and the main focus is how to cook and hold rice economically. Of course, this problem is also an important issue and can not be ignored. Naturally, it is a matter of course that the natural incorporation of minerals that cannot be generated in the body is a problem that must be solved in order to improve and maintain health.
[Means for solving problems]

In the case of a heating method by electromagnetic induction, a test is performed to detect the best point of the thickness and compatibility of the innermost magnesium alloy that has been teflon processed in the inner pot of the rice cooker, and the human body according to the strength of ionization tendency of minerals after Teflon processing For this prototype to be rigorous to test the effect of the effect, it is necessary to solve the thickness, productivity, economic and various problems of rolling, pressing and teflon processing to the thickness possible of magnesium alloy.
[The invention's effect]

When cooked in a rice cooker using this material, the amount of mineral (magnesium) ingested and absorbed by the human body increases and is effective for health promotion. In addition, the heater heating method is lightweight and saves electricity due to the heat conduction effect.
[Best Mode for Carrying Out the Invention]

Regardless of the use of alloys specified in JIS standards, it is necessary to develop alloys with better extensibility and workability for inner pot manufacturing, and in the future, we will collaborate with machining and food related societies to improve productivity and health. I think it should be tested to be effective for promotion.
[Example]

Completing trial production of the inner pot with the heater heating method and taking data, overheating, mineral content,
As shown below Heating temperature Mineral 4.62 ppm.
Heating time (including heat retention) 30 minutes or more [industrial applicability]

Magnesium is a metal that will help reduce industrial waste in the future because it is easy to recycle.

Claims (2)

Manufacture of the inner pot of an electric rice cooker using materials with good extensibility such as magnesium alloy composition and mechanical properties currently specified in Japanese Industrial Standards (jis). In the case of an electric heater heating method using a magnesium alloy, the thickness is adjusted to suit each case, the electric heating effect is increased, and the mineral (Mg) penetrates into the cooked rice due to the ionization tendency of the magnesium, which helps to promote human health adjust.
