Description

{Fabrication of scoria coffee cup}

The present invention relates to a method for manufacturing a coffee cup, and more particularly, to a method for preserving the taste and aroma of a coffee using a volcanic cluster of Jeju Island and proposing a new coffee cup capable of satisfying the atmosphere of coffee drinking and the cultural elements of the coffee do.

Along with the development of human culture, coffee is a favorite drink for tea. Although coffee originated in Africa in the past, it has been expanding its cultivation area throughout the world including Asia and South America through the colonial period. Despite the many side effects such as plantation farms and low wage labor, production and consumption have increased each year, Of the world's oil.

In Korea, as the standard of living has increased, the amount of coffee consumption has increased, leading to consumption in the top 10 in the world. In terms of per capita consumption, more coffee is consumed than Japan. In particular, in the past, coffee beans led the coffee market in the culture centered on instant coffee, and consumers' taste to enjoy the flavor and aroma is becoming more diverse.

Coffee can be different according to the taste of coffee shops and coffee lovers because coffee flavors are different according to the kind of bean of origin, roasting method of coffee bean, degree of grinding, and extraction method such as coffee machine or hand drip. This diversity of coffee is harmonized with the modern life pattern, and coffee culture is created and the additional industry is expanded accordingly.

The place and atmosphere of drinking coffee is also very important factor when you drink coffee, especially the coffee cup. The coffee cup is mainly made of a heat-resistant magnetic material so that the temperature of the hot coffee is not easily deteriorated. Depending on the type of coffee, the shape and size of the coffee cup may vary. For example, an 80 ml capacity demitase for espresso, a cappuccino cup for 220 ml of cappuccino coffee, a 250 ml hand drip cup, slightly larger than a cappuccino coffee cup, And a versatile mug coffee cup that can drink large amounts of coffee such as cafe latte and americano, which have a large capacity of 320 ml.

These coffee cups are mostly made of white porcelain, with different sizes depending on their capacity. The white coffee cup has a psychological disadvantage that it does not match with the oriental teacup in contrast to the black coffee color, and it is troublesome to preheat the hot coffee with hot water in order to preserve the heat of the hot coffee. In addition, when the coffee is often stored or used for a long time, the color of the coffee remains in the cup and the appearance is not good.

On the other hand, there has been proposed a technique of removing the bitter taste or the bitter taste of coffee using a material generating far-infrared rays during the production of coffee beans, or changing the caffeine to a mild taste by neutralizing the caffeine (Japanese Patent Laid-Open No. 1997-59145, 5939). Such prior art is merely intended to apply only far-infrared ray radiation, which is a basic property of a general ceramic product, to a coffee cup, and it is insufficient to improve the material, color and other functions of the coffee cup considering the taste and aroma of the coffee. In addition, there are limitations in the technology for selecting a coffee-specific material or a coffee cup considering the cultural factors of the coffee.

The present invention has been developed under the technical background described above, and an object of the present invention is to provide a coffee mug which can be well mixed with the color of coffee as well as the taste and aroma of coffee.

Another object of the present invention is to provide a method for manufacturing coffee beans which can optimize the appearance, texture, color and the like by selecting a new material suitable for coffee.

Other objects and technical features of the present invention will be more specifically described in the following detailed description.

In order to attain the above object, the present invention provides a method for producing a volcanic ash, which comprises the steps of: preparing a volcanic clay of Jeju; removing impurities; , And Sanshige soil were prepared, and the mixture was mixed with the pine clover powder at a weight ratio of 10-50%: base 90-50%, dried and pulverized to prepare a mixed powder having a size of 80 mesh to 200 mesh Mixing and kneading the water with the mixed powder, molding the coffee cup, locally repetitively applying the clay loam to the surface of the shaped coffee cup, applying the clay glaze to the surface of the formed coffee cup Drying the coffee bean coated with the gypsum and the glaze, and calcining the coffee bean while heating to 1000 to 1250 ° C.

The composition of the pine clay soil is preferably 35 to 55% by weight of Jeju soil, 15 to 35% by weight of clay, 15% by weight of silicate and 15% by weight of water.

The gypsum composition is blended in a weight ratio of 25-40%, limestone 15-40%, and Jeju soil 30-60% by weight, and 30-40% water is mixed with the total weight of the glaze composition to complete the gypsum glaze .

In the present invention, the dough mixed with the germinated powder and the substrate may further include a step of aging for a week, and the germinated material is first dried on a dry cloth, secondarily dried on paper, Stepwise drying can be carried out in a manner of third natural drying.

According to the present invention, it is possible to provide a coffee cup having unique color and texture through mixing of clay and volcanic clusters, and having a high far infrared ray emissivity and radiant energy, and having excellent functionality. The present invention establishes basic processes in the production of various household goods using volcanic clusters in addition to volcanic clusters, and systemizes the production efficiency of mass production and actual products, and minimizes the process for the completion of products.

In addition, the present invention can expect the development of the local industry through the commercialization of the volcanic clusters, the technology development utilizing the volcanic clusters, and the production of the local ceramic products linked thereto, and thus the development of the related industry can be expected.

The present invention proposes a method of manufacturing a coffee cup which is effective in preserving texture and color and flavor and aroma of coffee by developing and utilizing scoria pottery and glaze samples.

In particular, the present invention analyzes the mixing effect of volcanic rocks and other soil components in order to expand the availability of volcanic clusters in terms of localization / environmental / future environmental resources, And suggest directions for development of goods and tourism products.

The method for producing a volcanic clay cup coffee according to the present invention can provide a new pottery product capable of maximizing the coffee atmosphere through color and texture while having functionality suitable for the taste, aroma, and atmosphere of coffee. For this purpose, Jeju Volcanic Cluster is used as a basic raw material, and other forms are mixed to improve formability, functionality and sinterability. For the production of the volcanic clay cup, the volcanic clusters of Jeju are purchased, the impurities are removed, dried and then crushed to prepare the crushed powder of 80 mesh to 200 mesh size. In addition to the cluster powder, the base material is selected from among at least one material selected from Celadon soil, Onggi soil, Mold soil, Donggol land, and Sanggol soil.

The volcanic rock material of Jeju Island is volcanic rock material which is formed by bubbling rapidly when the volcanic eruption occurs in Jeju Island. It is a porous volcanic rock material with a small amount of organic impurities and contains a large amount of iron, so it is changed from ivory to dark brown Various colors can be expressed up to. Therefore, the volcanic mushroom coffee mug can be utilized as a new concept coffee mug that can escape from the existing white coffee mug and harmonize with the coffee color, thereby further enhancing the mood of the coffee.

It can also be used as far-infrared radiation material such as minerals and loess, because it has hygroscopic, absorption, and far-infrared radiation function. For example, in the hot and humid city of Jeju, volcanic clusters were used as a soundproofing and desiccant on roofs and walls of houses. They were also used as a filter to prevent radiant heat on roads and to prevent muddy water during rain. Therefore, when using the volcanic clay as a coffee bean material, it is possible to prevent penetration of other substances as well as keeping warm, and it is possible to preserve the original taste and aroma of the coffee, and to add depth of coffee taste through far- It is expected to be.

It is preferable that the mixture of the pine powder and the substrate, which are the material of the coffee cup, be mixed at a ratio of 10-50%: 90-50% of the pine by weight. As the ratio of the volcanic clusters increases, various effects of the above-described volcanic clusters can be obtained. However, due to the low moldability and sinterability of the volcanic clusters as described later, it is desirable to improve the productivity and production efficiency by containing other components . The mixed materials are dried and then pulverized to prepare a mixed powder having a size of 80 mesh to 200 mesh.

Since the pine mushroom is a non-viscous material, it is difficult to produce the pine mushroom specimen. Therefore, celadon, Onggi, combination soil, Sancheong soil, D1 white porcelain, black white porcelain, white clay, sainto, and black can be used. The addition ratio can be determined in consideration of the improvement of the cluster viscosity so that the selected substrate can function as a color harmony with the cluster and as a complement to the cluster.

The mixed powder of clay and ground is mixed with water, kneaded, and molded into a coffee cup. It is possible to vary the color of the surface of the coffee cup after firing by locally repeating the application of the clay loam on the surface of the formed coffee cup.

In the case of forming a coffee cup, it is possible to make it with a form that can express the functional utilization of the cup as a main point and in consideration of a set of a cup and a drier as a basic coffee in the future. Especially, size, color, atmosphere, function and so on can be used to form coffee cups, espresso cups and mugs of appropriate size and shape coming into one hand. For example, a mug has a high shape, a coffee cup has a wide mouth, and an espresso cup is formed with a ratio of the overall size as a center, while a handle can be attached to a molded coffee cup considering the shape of a coffee cup have. After the coffee cup is formed, it is dried and aged, and then the plasticization can be prepared through the complete drying process.

The surface of the molded coffee beans is coated with the clayey soil containing clay components. The clayey soil can be prepared in a completely dry state after the application of the clayey soil without applying the clayeye at a time. After the proper drying process is completed, the completed prototype is completed and then subjected to sieving and firing. It is preferable to apply a gypsum glaze to the surface of the molded coffee cup together with the pine clay. The composition of the pine clay soil is preferably 35 to 55% by weight of Jeju soil, 15 to 35% by weight of clay, 15% by weight of silicate and 15% by weight of water. The gypsum composition is blended in a weight ratio of 25-40%, limestone 15-40%, and Jeju soil 30-60% by weight, and 30-40% water is mixed with the total weight of the glaze composition to complete the gypsum glaze . Pine clay is suitable for producing more harmonious colors of the volcanic clay mug with more coffee color, doubling the mug of coffee cup with the mug of coffee mug. The glaze glaze also enhances the functionality of the coffee cup due to the glaze composition along with the gloss effect and surface coating effect of the coffee cup.

The coffee cup coated with the clay and the glaze is dried and fired while raising the temperature to 1000 to 1250 ° C. The surface of the semi-dry molding may be coated with a clay loam, followed by drying, followed immediately by firing, followed by baking with a clay glaze after applying the clay loam.

Hereinafter, the manufacturing process according to the present invention and the function of the produced volcanic cup coffee mug will be described in more detail with reference to the preferred embodiments.

Example

1) Clover raw materials and raw materials

The volcanic pine mushrooms used pine mushrooms from Songyu Industry Co., Ltd., and the other raw materials such as Cheongja, Onggi, Choongpo, Donggong, and Sancheong were used for defense of Daewon ceramics and stoneware. Jeju soil, which was used as a raw material of the clay soil, was collected from the soil near Shinchang-ri, Seogwipo city, Jeju Special Self-Governing Province. The gypsum and woks used as raw materials for glaze composition were purchased from Daewon Ceramics, a supplier of ceramics materials.

Since the pine mushroom has not been refined containing various byproducts such as moisture content and debris, the pine mushrooms having a diameter of 3 cm or less were selected, and the pine mushrooms were collected in a collection bag, and then the by-products were washed out with natural wind. The clusters were classified according to size and use, and the clusters were removed by filtering with 80 mesh (mesh, mesh), 100 trees, and 150 necks, and the size was classified in stages. Separate clusters by application were dried to separate the moisture contained in the raw materials. The drying process of the water separation proceeded in several steps as shown in FIGS. 1A and 1B. It was dried by spraying the pine mushroom on the first dry cloth, and the drying process was carried out periodically by the drying process by time. Secondly, by using the water absorption capacity of the newspaper, it was continuously replaced and dried. After the natural drying process of sunlight and wind, the raw material of the pine mushroom which can be finally utilized is secured. The dried clusters were stored in an airtight container to block the moisture in the air, and were maintained in a dry form through ventilation of the airtight container periodically. The final dried pine cluster was pulverized through a small crusher and pulverized.

2) Molding and baking of products

The specimens were selected according to the degree of magnetization of the sintering temperature of 1250 and the degree of lightness of the sieve + base, and the aesthetic color considering the appearance of the prototype was designed, .

The selected specimens were mixed with water to make dough, dried and aged for 1 week, and then molded into a cup of coffee. On the surface of the molded coffee mug, a clay loam was applied, and after clay loam application, the clay glaze was applied again (see Fig. 2a).

In the present invention, the clay soil of the clay component is applied to the surface of the molding to improve the color diversity and the functionality of the clay so as to compensate for the coarse component of the soil before the ceramics firing process. The soil composition of the present invention was prepared by mixing silica powder, clay powder, and Jeju soil powder. Considering the final color of the coffee cup, the creams were applied repeatedly to the desired area or area without applying the entire composition at once.

Next, the glaze containing the cluster component was applied to the surface of the molding (see Fig. 2B). The composition of concrete gypsum glaze is shown in Table 3.

Finally, the firing was carried out. Because of its inherent low refractoriness, the pine was slowly heated to a temperature of 1000 ° C to 1100 ° C and 1250 ° C, which is the minimum temperature for basic ceramics. The magnetization at 1000 ° C was not high enough to be used as a prototype. At 1100 ° C, the cluster melted properly but the substrate was not baked, and the final temperature was selected at 1250 ° C.

3) Functional evaluation

To confirm the function of the fired coffee bean specimen with the application of the gypsum and glaze, we commissioned the far infrared ray inspection of Korea Ceramic Technology Institute. The test specimens with the test results were mainly bonded with iron-rich substrates. The composition of the ground and pine mushroom was the same as that used in Table 1, and the composition of the creosote was A component in Table 2, And the test results of each specimen are shown in Table 4. FT-IR Spectrometer (USA MIDAC M 4400-2-25) was used for the functional test analysis, and the measurement results of the black body were more specifically shown in Figs. 3A to 5B for each sample. Far infrared ray emissivity of 0.942 ㎛ and radiant energy of 23.879X10 ² W / ㎡ or more.

4) Final product

Figs. 6 and 7 show the appearance of a volcanic clay cup manufactured according to a preferred embodiment of the present invention.

The shape of the coffee cup is designed so that the overall height is smaller than the mug size and the entrance has enough coffee capacity to enable hand dripping. Using a straight shape, the knobs were squeezed into a gypsy stone that matched a not-so-great cup, completing the texture and shape. The depth and thickness were given to induce the bottomed coffee to cool slowly.

In particular, the texture and color of the inside and outside are dark brown which can be harmonized with the color of coffee, and various changes of surface pattern and color are realized by using pine clay loam and clay glaze. In addition, the contrast and color of exterior and interior colors could be obtained by changing the use and amount of the use of the creams on the outside and inside of the coffee cup.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modified, modified, or improved.
