SCORCHED RICE MAKING DEVICE

Technical Field

[1] The present invention relates to a scorched rice making device. More particularly, the present invention relates to a device for making scorched rice without burning it or sticking it on a bottom of the device while having no negative influence on a human body.

Background Art

[2] Generally, when rice is cooked by an old-fashioned rice cooking device, the rice sticks on the bottom of the device and is naturally scorched at the bottom. It tastes savory, is crunchy, and contains various nutritive elements, so it is used as a snack or a substitution for a meal.

[3] It has been difficult to cook scorched rice that is naturally formed since an electrical rice cooking device is generally used, and therefore scorched rice has recently been artificially made by scorched rice making device in factories.

[4] Since rice consumption may increase as people eat more scorched rice, a crisis of the rice market that may be caused by rice market openings according to potential international free trade agreements (FTAs) and by various instant foods needs to be overcome.

[5] Accordingly, it is required to mass-produce the scorched rice that has higher quality and better nutritive elements than confectionery, bread, and ramen that mainly consist of flour.

[6] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Disclosure of Invention Technical Problem

[7] The present invention has been made in an effort to provide a scorched rice making device for mass producing scorched rice without burning it or generating any harmful ingredients since rice is scorched when the rice touches basalt having a good absorption rate and natural mineral components, and is flattened. Technical Solution

[8] An exemplary scorched rice making device according to an embodiment of the present invention includes an upper pressure plate, a lower pressure plate, and at least one up-down reciprocating unit. The lower pressure plate faces the upper pressure

plate while having a predetermined gap therebetween, and includes a scorched rice raw material on an upper surface of the lower pressure plate. The at least one up-down reciprocating unit reciprocates at least one among the upper and lower pressure plates to flatten the scorched rice raw material. At least one of the upper and lower pressure plates generates heat to scorch one surface or both surfaces of the flattened scorched rice raw material.

[9] The upper pressure plate includes a body formed in a plate shape by a material having excellent conductivity, a heat generating element that is mounted inside the body and generates heat as electricity is supplied, and a coating unit that is formed on a surface of the body, and the lower pressure plate is formed by manufacturing basalt in a plate shape.

[10] The up-down reciprocating unit uses one or more cylinders respectively including a piston rod connected to the at least one of the upper and lower pressure plates.

[11] In addition, the scorched rice making device further includes a guide member for supporting the at least one of the upper and lower pressure plates so that the at least one of the upper and lower pressure plates may be reciprocated upward and downward. Brief Description of the Drawings

Best Mode for Carrying Out the Invention

[23] A scorched rice making device according to an exemplary embodiment of the present invention will be described with reference to the figures.

[24] As shown in FIG. 1 to FIG. 4, the scorched rice making device according to the exemplary embodiment of the present invention includes an upper pressure plate 10, a lower pressure plate 20, an up-down reciprocating unit 30, and at least one guide member 40. The lower pressure plate 20 is provided on a lower part of the upper pressure plate 10, and a scorched rice raw material 2 is provided to an upper surface of the lower pressure plate 20. The up-down reciprocating unit 30 reciprocates the lower pressure plate 20 in upper and lower directions to flatten the scorched rice raw material 2. The guide member 40 supports the lower pressure plate 20 so that the lower pressure plate 20 may be reciprocated in the upward and downward directions.

[25] In addition to rice, barley, beans, kimchi, mushrooms, sweet potatoes, potatoes, pumpkin, ginkgo nut, black rice, mung beans, adlay, fermented soybean paste, perilla seeds, corn, bracken, lotus root, and burdock may be provided to the scorched rice raw material 2.

[26] The upper and lower pressure plates 10 and 20 are formed in a quadrangle shape, and may be formed in a circular shape as shown in FIG. 9. In addition, while it is not described in the figures, they may be formed in various shapes including polygonal and oval shapes.

[27] As shown in FIG. 3 and FIG. 4, the upper pressure plate 10 includes a body 12, a heat generating element 14, and a coating unit 16. The body is formed of a material having excellent conductivity and that is plate- shaped. The heat generating element 14 is mounted inside the body 12 and generates heat as electricity is supplied. The coating unit 16 is formed on a surface of the body 12.

[28] The body 12 may be supported by a supporting case 13 except at one surface of the body 12.

[29] The upper pressure plate 10 scorches one surface or both surfaces of the scorched rice raw material 2 that is formed to be flat as the heat is generated.

[30] The one surface of the scorched rice raw material 2 is firstly scorched once as it is formed to be flat between the upper pressure plate 10 and the lower pressure plate 20. Subsequently, the upper pressure plate 10 and the lower pressure plate 20 are spread apart, the scorched rice raw material 2 is turned upside down, the upper pressure plate 10 and the lower pressure plate 20 are brought together again and the other surface is scorched, and therefore both sides of the scorched rice raw material 2 are scorched.

[31] The upper pressure plate 10 may be formed in the same configuration as an

electrical oven, a cooking vessel, or a cooking pan. [32] A temperature of the body 12 of the upper pressure plate 10 may be within a range of 120 to 25O ⁰ C. [33] As shown in FIG. 1 to FIG. 3, basalt is manufactured in a plate shape to form the lower pressure plate 20, and an upper surface of the lower pressure plate 20 faces a lower surface of the upper pressure plate 10 while having a predetermined gap between the lower pressure plate 20 and the upper pressure plate 10. [34] A supporting member 24 surrounds the lower pressure plate 20 to protect the lower pressure plate 20 from impact or weight. [35] For example, as shown in FIG. 5, the supporting member 24 is formed in a shape that surrounds end surfaces and the lower surface of the lower pressure plate 20 (i.e., a

[ shape), or it may be formed in a shape that surrounds the end surfaces and edges of the lower surface of the lower pressure plate 20 (i.e., an L shape) as shown in FIG. 6. [36] The up-down reciprocating unit 30 includes a plurality of cylinders 32 including piston rods 34 that are connected to the up-down reciprocating unit 30. [37] Each cylinder 32 is uprightly mounted on a floor so that the piston rod 34 may stand upright, and the piston rod 34 and the lower pressure plate 20 are integrated. [38] A hydraulic cylinder or a pneumatic cylinder may be used as the cylinder 32.

[39] When a hydraulic cylinder or a pneumatic cylinder is used as the cylinder 32, a pressure generator such as air compressor or a hydraulic motor is used. [40] As shown in FIG. 7, the up-down reciprocating unit 30 may further includes a foot switch valve 36 that is operated by stepping on it to operate the cylinder 32 to bring the upper pressure plate 10 and the lower pressure plate 20 together while providing the scorched rice raw material 2 therebetween. [41] The foot switch valve 36 moves the cylinder 32 up and down when a user steps on it. [42] As shown in FIG. 8, the up and down reciprocating unit 30 may further include a timer 38. The timer 38 operates the cylinder 32 so that the upper pressure plate 10 and the lower pressure plate 20 may come apart after a predetermined time passes while the upper pressure plate 10 and the lower pressure plate 20 are together having the scorched rice raw material 2 therebetween. [43] The timer 38 is set such that the upper pressure plate 10 moves apart from the lower pressure plate after 2 to 5 minutes when the temperature of the upper pressure plate 10 is approximately 15O ⁰ C to 25O ⁰ C. [44] As shown in FIG. 1 to FIG. 4, an upper end part of the guide member 40 is fixed to the upper pressure plate 10, and a middle part is penetrated through the lower pressure plate 20 to be fixed to the floor. [45] The guide member 40 may be formed in a pipe shape.

[46] As shown in FIG. 10 and FIG. 11, a plurality of guide members 40 may surround corner parts of the lower pressure plate 20.

[47] For example, four bars formed in an L-shape are provided to the corner parts of the lower pressure plate 20 to form the guide members 40 when the lower pressure plate 20 is formed in a rectangular shape.

[48] The guide member 40 may be formed to support the upper pressure plate 10 such that the upper pressure plate 10 may be above the floor by a predetermined height. That is, an upper end part of the guide member 40 is fixed to the upper pressure plate 10 and a lower end part thereof may be fixed to the floor.

[49] The upper pressure plate 10 may be supported from the floor by using an additional supporting member 50.

[50] While it is not illustrated in the scorched rice making device according to the exemplary embodiment of the present invention, the up-down reciprocating unit 30 may alternatively reciprocate the upper pressure plate 10 so as to flatten the scorched rice raw material 2.

[51] In this case, in the cylinder 32 of the up-down reciprocating unit 30, the piston rod

34 is connected to the upper pressure plate 10.

[52] In addition, while it is not illustrated in the scorched rice making device according to the exemplary embodiment of the present invention, the up-down reciprocating unit 30 may alternatively reciprocate the upper pressure plate 10 and the lower pressure plate 20.

[53] While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Industrial Applicability

[54] According to the scorched rice making device according to the exemplary embodiment of the present invention, the flattened scorched rice may be produced since the upper pressure plate and the lower pressure plate move together by the up- down reciprocating unit while providing the scorched rice raw material between the upper and lower pressure plates, and therefore the scorched rice may be conveniently mass produced.

[55] Since the scorched rice raw material is provided on the lower pressure plate formed of basalt and the lower pressure plate moves upward to the upper pressure plate that is heated to produce the scorched rice, the basalt absorbs water from the scorched rice raw material and the water is evaporated. Therefore, the scorched rice raw material is

not burned but is appropriately cooked. [56] Accordingly, since it is not required to use cooking oil, the cost may be reduced, and elements having a bad influence may be prevented from entering a human body. [57] Further, since the up-down reciprocating unit is operated by stepping on the foot switch valve and a scorching time is controlled by the timer, uniform quality of the scorched rice may be mass produced, and human resources and time may be saved.
