Description

Heat-resistant container for food cooking with coating of exothermic glaze and its manufacturing method

The present invention relates to a heat-resistant container for food cooking, and more particularly, it exhibits the effect of improving the thermal efficiency by allowing high temperature heat generation inside the container during cooking of food, especially when cooking food of meat or fish It relates to a heat-resistant container and a method of manufacturing the same for coating a heat generating glaze on the inner surface in order to exhibit a baking effect.

Our nation has long had a diet based on its own fermented foods, and onggi, such as earthenware and earthenware, have stayed around our lives for as long as these foods.

Even though the pot is a heat-resistant container used to boil stew or Korean soup, it does not crack even if it is rapidly heated at low temperature.

However, such a conventional heat-resistant container has a problem of lowering energy efficiency because it takes a relatively long time to heat the food inside to a certain temperature due to its heat resistance.

In other words, when cooking food such as fish in a heat-resistant container and cooking using a direct fire or microwave oven, the cooking time is inevitably increased since the thermal conductivity is lower than that of a general stainless steel cooking container.

The present invention has been proposed to improve the thermal efficiency problem in the food cooking process of the conventional heat-resistant container, the purpose is to increase the heat efficiency when cooking food using the heat-resistant container to make the food of the cooking more quickly and efficiently. have.

In the present invention for achieving the above object, in the heat-resistant container for food cooking, the heat-resistant glaze layer containing limestone, talc, clay, ferrite, iron oxide, lithium frit, lithium carbonate, ferrite component on the inner surface of the heat-resistant container It is characterized by providing a coated heat-resistant container structure and its manufacturing method.

In the present invention, when the heat-resistant container is heated in a stove such as a microwave oven or a gas stove, the internal temperature rapidly rises in a fast time, so that food may be cooked as well as baked.

In particular, in the manufacturing process of the heat-resistant container it is possible to improve the exothermic properties by separately producing a heat-generating glaze other than the general glaze by forming a heat-generating glaze layer on the inner surface of the container.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the manufacturing process of the heat-resistant container according to the present embodiment will be described with reference to the flowchart of FIG. 1.

Various materials may be used as a raw material for the manufacture of the ceramic heat-resistant container, but in this embodiment, 45-50% by weight of petalite, 0-5% by weight of fluorine, 35-50% by weight of clay, and 5-15% by weight of clay. A raw material blended with was used.

At this time, the petalite (petalite) is a lithium-aluminum silicate mineral, which is light-transmissive enough to be used as a mining material of a barn, and has light and durable characteristics. Not only glass gloss but also glass composition, the coefficient of thermal expansion is extremely low, and resistance to rapid thermal shock is large. Petalite should be finely pulverized to about 320mesh when used as a glaze, but may be pulverized within the range of 20-30mesh in the use of a firing vessel such as the present invention. However, since the solubility is lower than that of clay, if the component content is increased by 50% or more, the moldability is likely to be lowered.

Lithium ore is a lithium-aluminum silicate mineral with a complex component containing calcium, magnesium, iron (II), iron (III), titanium, aluminum, etc. Can be used. Lithiarite is a natural mineral that is a mixture of aluminosilicates of lithium and sodium, and two of the common minerals are 'kunchite' and 'hiddenite'.

Clay is handled differently depending on the industry, but is usually defined as fine soil particles with a diameter of 0.004 mm or less. It is a mineral obtained from the earth's crust, and has a larger surface area per unit weight than sand or silt, which has a strong water retention. Ore types of clay minerals include kaolin, bentonite, porcellanite, etc., and kaolin, ball clay, refractory clay, china clay as a mixture of alumina and silica. It may also include substances such as the like. Preferred clays are those that express high plasticity, such as ball clay and refractory clay.

The clay content is 35-50% by weight but can be increased to 55% by weight, in which case the petroleum is reduced by that increase.

White clay is a pure white clay, which refers to white clay or kaolin, and a slightly gray one can be white by hot firing. Excellent viscosity and plasticity are maintained even when a small amount is used, and excellent light transmittance is exhibited due to the whiteness. Depending on the application of the ceramic vessel, the function of the viscosity or the whiteness is adjusted.

In the container molding process, the kneaded dough is put in a mold or molded using a spinning wheel.

That is, at this time, as shown in Figure 2 may be molded into a heat-resistant container product having both the container body 10 and the lids (11, 12), or may be molded into a product without a lid, such as casserole.

Subsequently, by performing the first baking for about 8 hours at 800 ~ 1000 ℃ the molded ceramic container to make a general magnetic or heat-resistant magnetic products.

Then, the heating glaze of the present invention is evenly applied to the inner surface of the container by using a brush or a spray on the container having the first roasting.

At this time, the exothermic glaze used is limestone, talc, white earth, ferrite (leafstone), iron oxide, lithium frit, lithium carbonate, ferrite components, in this embodiment limestone 5% by weight, talc 5% by weight, clay 5 Powder components, which are mixed in a proportion of 20% by weight, 20% by weight of ferrite, 10% by weight of iron oxide, 20% by weight of lithium frit, 5% by weight of lithium carbonate, and 30% by weight of ferrite, are mixed with water in a ratio of 40: 60% by weight. An exothermic glaze prepared by using the same was used.

Among the components constituting the composition, ferrite performs a heat-resistant function, limestone, talc and white soil have a stickiness, lithium carbonate performs a peptizing function that is well soluble in water, iron oxide frictional force by electromagnetic waves when using a microwave oven Maximizes the heating value by increasing the amount of lithium frit prevents ferrite and other components from cracking, and ferrite performs the action of improving the exothermicity.

Through the above process, the container in which the exothermic glaze is coated is naturally dried for about 4 to 8 hours so that the exothermic glaze layer of the thin film is evenly formed, and finally, the conglomerate is roasted for about 10 hours at a temperature of 1220 to 1280 ° C. By performing the high-strength heat-generating heat-resistant container is completed.

2 is a cross-sectional view showing an example of the heat-resistant container completed through this process, the upper lid 11 and the inner lid provided in the interior of the container body 10 seated on the upper portion of the container body (10). It is made of (12), it can be seen that the bottom surface of the inner lid 12 and the bottom surface of the container body 10 has a plurality of protrusions (10a, 12a) having a predetermined interval is formed in an integral structure.

In particular, as shown in the partial enlarged view, it can be seen that the heat generating glaze layer (C) is formed on the inner surface of the container body 10, respectively.

In addition, the heat-generating glaze layer (C) is preferably formed evenly on the surface of the bottom surface of the upper lid 11 and the inner lid 12 as well as the container body (10).

When the fish is put into the heat-resistant container of the present invention thus prepared and cooked in a microwave oven, the temperature of the container is quickly increased by the action of the exothermic glaze layer C, and the food cooking time is shortened. In particular, food such as meat and fish will be able to exhibit the baking effect as well as cooking.

In fact, the conventional heat-resistant container and the heat-resistant container of the present invention was put into a microwave oven and heated for about 1 minute. As a result, the heat-resistant container of the present invention was measured at a temperature of 60 degrees, whereas the heat-resistant container of the present invention was 130 degrees or more. It can be confirmed that is measured.

In addition, by having a separate inner lid 12 to be placed on the food when cooking fish or meat will be able to exhibit a more efficient baking effect by the projections (10a, 12a).

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the process of manufacturing the heat-resistant container of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, the kneading material of the container is specified and described, but such kneading material may be added or excluded depending on the use and characteristics of the heat-resistant container.

Therefore, such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.
