  However, in the invention in Patent Document 1 or Patent Document 2, lava or barleystone is crushed into small particles and enclosed in a net container. Here, while cooking rice, it is immersed in hot water at around 100 ° C., and lava in the net container, or barley stone is repeatedly collided by hot water convection, and finely broken stone fragments flow out of the net container. There is a fear.

  In addition, when using it for cooking rice, the lava or barleystone adheres to the surface of the barleystone, and at this time the juice becomes paste-like due to heat, so the small granular lava or barleystone is solidified. . And after use, lava or barley stone is taken out from the net container and must be washed one by one until the juice is taken when it is pasty, and it takes a lot of work, and the surface of small granular lava or barleystone is There are problems such as the formation of mold and the occurrence of food poisoning due to decay due to the residue of the juice when it is uneven and paste-like.

  In addition, when the soup adheres to the mesh of the mesh container, the far infrared rays emitted from the lava and the mineral components eluted from the barley stone may not be sufficiently released, and the paste-like adhesive adhered to the mesh container Sometimes the washing of the juice is very time-consuming.

  The present invention was devised in view of the above points, and provides an auxiliary material for rice cooking that can be directly sown by refining oat stone, kneading it with ceramic clay, and firing it. It is the purpose.

  In order to achieve the above-mentioned object, the rice cooking auxiliary material according to the present invention is a sintered body including granulated barley stone and a binder that binds the barley stone.

  Here, the barley stone granulated by the pulverizer and the binder, which is a ceramic clay, are kneaded, molded into a predetermined shape in a state where the air is evacuated by a vacuum extruder or the like, and sintered at a high temperature. As a result, the surface becomes a very hard sintered body.

  The auxiliary material for cooking rice made of this sintered body can be used without being broken or broken by heat even if it is put together with rice and cooked in a rice cooker.

  In addition, mineral components are eluted by silicic anhydride, aluminum oxide, and iron oxide, which are the main components of granulated barley stone, and rice is activated by the far-infrared effect of trace elements such as panadium, zirconium, and strontium. It can be cooked into plump and delicious rice.

  Moreover, when the mixing ratio of the barley stone and the binder is 6 to 4, the effect of the barley stone can be obtained and the strength can be maintained by the binder. That is, it was confirmed that when the blending ratio of the barley stone exceeds 6 and the blending ratio of the binder is less than 4, the effect of the barley stone improves, but the strength of the sintered body decreases and becomes brittle. Furthermore, when the blending ratio of barley stone is less than 6 and the blending ratio of the binder exceeds 4, the strength increases, but a sufficient effect of barleystone cannot be obtained.

In addition, the barley stone combined by the binder is sintered at a temperature of 1,300 ° C. or higher, so that the surface of the sintered body becomes high hardness and innumerable holes are formed, so that it comes into contact with the soup. It is possible to increase the surface area and obtain a further elution effect of mineral components, and also to revitalize the rice by activating far-infrared rays and cook it into plump and delicious rice.
In addition, when sintered at a temperature lower than 1,300 ° C., the surface of the sintered body cannot obtain sufficient hardness, and when it is put together in a rice cooker and cooked, cracking may occur. For example, the surface of the sintered body may be scraped off when the juice is scraped off into a paste form.

  In addition, ceramic clay is clay-like soil used when making pottery, for example, soil produced in Arita, Saga Prefecture, or soil produced in Koishihara, Fukuoka Prefecture, etc. It is the most suitable binder for bonding barley stone and sintering at high temperature.

  According to the rice cooker auxiliary material of the present invention, the surface is very hard by making the barley stone fine, kneading with ceramic clay and baking at high temperature, cracking or breaking even if directly put in the rice cooker It is possible to use it safely.

  In addition, paste-like soup that adheres to the surface of the sintered body after cooking can be easily removed by rubbing it strongly with a metal scrubber or the like.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention.

In this example, andesite porphyry (hereinafter referred to as “barley rice stone”) mined in the Kujuyama Group of Oita Prefecture was used as the auxiliary rock.
The main components of this barleystone are anhydrous silicic acid, aluminum oxide, and iron oxide. In addition, trace amounts of oxides of titanium, magnesium, sulfur, potassium, calcium, and manganese are included. Trace elements such as panadium, zirconium, and strontium are also included. Contains a little.

  Here, since the excavated raw stone has a diameter of 10 cm or more, it is pulverized by a pulverizer in stages of coarse, fine and fine. Next, the finely crushed raw stone and the ceramic clay are blended at a weight ratio of 6: 4, and then kneaded to obtain auxiliary member materials.

  In addition, when the raw stone is crushed finely by a crusher, it is not always necessary to pulverize in three stages of coarse, fine, and fine, two stages of fine, fine, or It may be a single step with fine lines.

  Next, since the auxiliary member raw material is formed by a vacuum extrusion molding machine, the auxiliary member raw material is temporarily formed into blocks each having a size required for forming.

  Furthermore, the auxiliary member raw material temporarily formed for each block is formed into a cylindrical shape with the air being evacuated by a vacuum extrusion molding machine, and then dried at a temperature of 50 to 80 ° C. for 2 to 3 days. Cracking during sintering can be prevented by blending the ceramic clay with each other. Then, the dried cylindrical auxiliary member raw material is sintered at a maximum temperature of 1,300 ° C. (about 1.5 hours) by slowly raising the temperature over a period of 5 days with a tunnel kettle.

  And the cylindrical auxiliary member raw material after baking is cut | disconnected by a cutting machine for every fixed space | interval, and a chamfer of the cut surface periphery is completed.

  The auxiliary rice cooking material 1 completed by the manufacturing process described above is formed into a columnar shape as shown in FIG. 2 and baked at a high temperature so that countless holes 2 are formed on the surface thereof. ing.

  Minerals necessary for the human body by silicic anhydride, aluminum oxide, and iron oxide, which are the main components of barley stone contained in the rice cooking auxiliary material 1 by cooking this rice cooking auxiliary material 1 in the center of the inner pot of the rice cooker By eluting (iron, calcium, silicic acid, etc.) into water and radiating far-infrared rays with trace elements vanadium, zirconium, and strontium, the far-infrared rays act on the rice core, resulting in a boiled cooking .

  In addition, the trace elements vanadium, zirconium, and strontium contained in the barleystone are activated by water to have an antioxidant power, and the freshness of the rice cooked by the action of this antioxidant power is the auxiliary for cooking rice of the present invention. It is possible to maintain freshness for a longer time than when no material is used.

  In addition, the surface of the rice cooking auxiliary 1 after cooking is attached in a state where the juice is solidified when the rice is cooked, but since the auxiliary raw material is baked at a high temperature, the surface of the rice cooking auxiliary 1 is It is very hard and can be easily removed by rubbing with a scrubber or the like, and since the surface of the rice cooking auxiliary material is not damaged, the rice cooking auxiliary material can be used repeatedly semipermanently.

  Further, in this embodiment, the rice cooking auxiliary material has a columnar shape, but it is not always necessary to have a columnar shape. For example, it may be any shape such as a square shape or a plate shape, but vacuum extrusion molding. It is desirable to make the shape easy to mold by a machine.
