[Means and Actions for Solving the Problems]

 In order to achieve the above object, a device according to claim 1 is a "rice cooking sheet which can be cooked with rice interposed between a rice cooker and rice, wherein the sheet has a wavelength of 100 ° C. The gist is a rice cooking sheet characterized by being composed of fibers containing ceramics that efficiently radiate electromagnetic waves of 6 to 12 μm.

As shown in FIG. 1, the rice cooking sheet of the present invention is arranged on the inner surface of the rice cooking pot 4, and the sharpened rice 3 is put inside the rice cooking sheet 1 so that the rice can be wrapped. ing.

The rice cooking sheet of the present invention is a sheet made of fibers containing ceramics that efficiently radiate electromagnetic waves having a wavelength of 6 to 12 μm at 100 ° C. As the fibers in the rice cooking sheet, fibers having a core-sheath type or a sea-island type cross-sectional structure and mainly containing ceramics in the core component or the island component can be exemplified, but are not particularly limited. Polymers for synthetic resins such as polypropylene, polyester, and polyamide are suitable for use as the fiber material. The ceramics are not particularly limited as long as they have a function of efficiently radiating an electromagnetic wave having a wavelength of 6 to 12 μm at 100 ° C., for example, alumina (Al ² O ₃ ) ceramics, magnesia ( MgO) ceramics, zirconia (ZrO ₂ ) ceramics, titanium oxide (TiO ₂ ), silicon dioxide (SiO ₂ ), chromium oxide (Cr ₂ O ₃ ), ferrite (MO.Fe ² O ³ , M: Mn) ²⁺ , Fe ²⁺ , Co ²⁺ , Ni ²⁺ , Cu ²⁺ , Zn ^2+, etc.), spinel (MgO.Al ₂ O ₃ ), cerium (CeO ₂ ), barium (BaO), etc. ceramics, boron carbide (B ₄ C), silicon carbide (SiC), titanium carbide (TiC), molybdenum carbide (MoC), tungsten carbide (WC) carbide ceramics such as, Boron (BN), aluminum nitride (AlN), silicon nitride (Si ₃ N _4), those selected from the nitride-based ceramics such as zirconium nitride (ZrN), or a mixture of two or more, some have the baked The knot is suitable for use.

Fibers having such a structure are woven into a cloth shape, knitted into a net shape, or randomly collected and bonded to each other into a non-woven fabric by a conventionally known method. It can be made into a sheet. Note that, as shown in FIG. 2, the gap between the fibers 2 in the sheet 1 is preferably set so that at least rice grains 3 cannot pass through, that is, about 3 mm × 3 mm or less.

When the cooked rice sheet thus configured is placed in the rice cooker 4 as shown in FIG. 1 and the sharpened rice 3 is put in to cook the rice, the fibers 2 constituting the rice cooked sheet 1 have 100 fibers. Since ceramics that efficiently radiate electromagnetic waves with a wavelength of 6 to 12 μm at ℃ are included, the electromagnetic waves radiated from the ceramics heat not only the surface of rice but also water efficiently and evenly. The rice is steamed efficiently and the cooking time is shortened. Even when cleaning and drying this rice cooking sheet, the drying time is shortened by the action of the electromagnetic waves of the ceramics contained in the fiber, so there is no concern of bacteria in the air adhering, and a more hygienic rice cooking sheet is used. is there.

When rice is cooked using this rice cooking sheet 1, the rice cooking sheet 1 is interposed between the rice 3 and the inner surface of the rice cooker 4, and the rice may adhere to the inner surface of the rice cooker. Even if the rice is transferred to another container after cooking rice, if the edge of the rice cooking sheet is raised, the rice sheet becomes a bag and the rice is contained in it. It just needs to be transferred to a container so that it does not take time to transfer.
