Description

Manufacturing process of grill radiating the Distant Infrared Rays}

The present invention relates to a method of manufacturing a fire plate that emits far infrared rays, and more particularly, to a method of manufacturing a fire plate for maximizing the far infrared emission by coating the surface of ceramics with olivine.

Conventional fire plate is simply forming the plate using porcelain raw materials such as kaolin and blue clay, and only a glaze treatment on the surface to grill meat (including vegetables and other foods) using the same plate, The heat source is difficult to transfer the uniform heat to the inside and inside of the meat through the plate, so it takes a considerable time to fully cook the meat, and has a closed end where the outer part burns before the inside is cooked. This is because the heat of the hot plate heated by the heat source is not evenly transmitted evenly throughout the meat, but heat is sequentially transferred from the surface of the meat to the inside. This burned meat has a disadvantage that the consumers are reluctant to contain the ingredients that cause cancer as well as deteriorate taste.

Therefore, in the related art, as in the manufacturing method of the far-infrared ceramic baffle plate of Korea Patent Application No. 1996-0037809, the mineral which can emit far infrared ray is controlled to about 50%, mixed with the raw material of ceramics, and molded and produced the baffle plate by heat source. Although the whole meat can be cooked evenly by the far infrared rays, the ceramic fire plate 1 is directly mixed with the ceramic raw material 11, which can emit far infrared rays, and then forms the fire plate. Not only is it expensive, but it is an uneconomical way to consider that minerals containing far-infrared radiation are very expensive.

In addition, the ceramic platen (1), except for the far-infrared radiation is not much different from the previous plate, the surface tissue is not dense or is treated with a simple glaze, so that the meat clings to the end and the oil used after washing It is difficult to solve the problem that is difficult to remove.

Therefore, the present invention does not directly mix the far-infrared radiating material with the raw material of porcelain (ocher, clay, kaolin, white clay, fetonite) as in the conventional fire plate, but first pulverize the olivine gemstone finely to 620 ~ 325mesh size, Mixing the pulverized olivine powder with water to produce an olivine solution, and then coating the olivine solution on the porcelain surface formed in the shape of an unbroken plate and drying and heat-treating it to protect the taste of meat and the health of consumers at the same time. An object of the present invention is to provide a manufacturing method of a radiating plate emitting far infrared rays.

The present invention will be described in detail with reference to the accompanying drawings a manufacturing method of radiating a far infrared ray as follows.

First, pulverizing the olivine stone in 620 ~ 325mesh, and mixing the pulverized olivine powder and water in a ratio of 1: 9 ~ 1.5: 8.5 in volume ratio to prepare an olivine solution, and then molded into the shape of the plate Coating and drying the olivine solution on the surface of the porcelain, and putting the dried porcelain into a heating furnace and heat-treating it at a temperature of 900 to 1200 ° C.

The olivine 110 is also referred to as chrysolite or olivine (Olivine), and is a major coarse mineral belonging to the tetragonal system with a hardness of 6.5 to 7, specific gravity of 3.2 to 3.4, and chemical composition of (Mg, Fe). It consists of ₂SiO₄.

In addition, the olivine forms columnar crystals, and has high strength and dense structure. The pH is the highest among all minerals currently found, with a weak alkali of 8.2-8.5 and a far-infrared emissivity of 92% or more.

In the present invention fire plate 100 should be coated with olivine ore on the surface of the porcelain 11 for this purpose, the finer the degree of powder of the olivine, the better the coating state, if it is too fine, that is, when pulverized to 620 mesh or less The cost of crushing is too great to have the disadvantage of economical efficiency, when pulverizing more than 325 mesh, because the particles are too large after the heat treatment of the heat plate 1 of the present invention has a disadvantage that the small cracks on the surface The crushing range of the olivine gemstone is most preferably 620 ~ 325mesh.

At this time, the mixed amount of the olivine powder and water should be mixed at a ratio of 1: 9 to 1.5: 8.5 by volume, but should be uniformly mixed.

The method of coating the olivine solution on the fire plate may be used in various ways, but in the present invention, the plate was put in and removed from the container containing the olivine solution for uniformity of the coating.

Drying of the step is preferably to be naturally dried at room temperature, heat treatment of porcelain is only one attempt to weaken the strength, the heat easily occurs, and this is because the product quality is deteriorated, so try divided into two times first and second It is desirable to. At this time, the temperature of the primary heat treatment is 900 ℃, the temperature of the secondary heat treatment is preferably 1200 ℃.

In the present invention, the shape of the bull plate may have a shape in which the center is convex and lower toward the edge, but on the contrary, the center may have a concave center and a container shape having only a high edge.

Hereinafter, the present invention will be described in detail by way of examples.

Example 1

The olivine gemstones collected from Goseong-gun, Gangwon-do were put into a grinder and pulverized to 620mesh, and the olivine powder was mixed with water 1: 9 to prepare an olivine solution.

Next, the olivine solution was coated on the surface of the porcelain formed in the shape of a plate and dried naturally. The dried porcelain was placed in a heating furnace and heat-treated at a temperature of 900 ° C., and the first heat-treated porcelain was again heated at 1200 ° C. By heat treatment with the present invention it was possible to produce a fire plate emitting the far infrared ray of the present invention.

Example 2

The olivine gemstones collected from Goseong-gun, Gangwon-do were put into a grinder and pulverized to 325mesh, and the olivine powder was mixed with water at 1.5: 8.5 to prepare an olivine solution.

Next, the olivine solution was coated on the surface of the porcelain formed in the shape of a plate and dried naturally. The dried porcelain was placed in a heating furnace and heat-treated at a temperature of 900 ° C., and the first heat-treated porcelain was again heated at 1200 ° C. By heat treatment with the present invention it was possible to produce a fire plate emitting the far infrared ray of the present invention.

Far-infrared radiation dose of the platen prepared in Example 2 is shown in Table 1 in comparison with olivine gemstones.

Sample Name Measurement temperature (℃) Wavelength band (㎛) Emissivity (%) Radiation energy (w / ㎡.㎛) Olivine gemstone 37 5-20 93.2 3.59 × 102 Invention plate 200 4-20 90.5 2.18 × 103

As described above, the present invention plate 100 does not have a large difference in the amount of olivine gemstones and far-infrared radiation, and because of this, the present invention plate radiates large amounts of far-infrared rays, which are beneficial to the human body. You can enjoy the tender meat taste.

In addition, the fire plate coated with far-infrared rays has a dense surface structure so that meat is hard to stick and oil is easily removed.

       In the present invention, the plate is coated with the surface of the plate formed of porcelain using the olivine with the highest amount of far-infrared radiation, and when the meat is grilled, far-infrared rays are radiated deeply in the meat, so that the heat of penetration is evenly applied to the meat. It is cooked uniformly, and it is possible to improve the aesthetics of meat while at the same time providing sufficient benefits to the human body by breaking down the fat of the meat.

           In addition, since the surface of the present invention is very hard surface is semi-permanent and the meat is not pressed well, it is a very useful invention that can provide economic benefits to the users do not need to replace the plate frequently.
