Description

Roll rice maker

[0001] One embodiment of the present invention relates to a roll rice manufacturing device, and more specifically, to a roll rice manufacturing device that increases the distribution period of rice and automates the processing of rice to enable mass production of kimbap and the like.

[0002] Recently, a variety of processed rice products that can be consumed as meal replacements, such as kimbap, triangle kimbap, and nurungji, have been released. However, kimbap and triangle kimbap have a shelf life of less than 24 hours, and most are produced by hand, making production and distribution inefficient. Furthermore, nurungji is produced by placing rice thinly in a disc-shaped mold and applying heat to the surface. However, the process of placing the rice, heating it, and removing it from the mold must be performed manually, resulting in low production efficiency.

[0003] To solve these problems, a roll rice manufacturing device according to Patent Document 1 was proposed.

[0004] However, with the technology introduced in Patent Document 1, it was difficult to make the roll rice thinner, and there was a problem in that it was difficult to appropriately control the heating temperature while producing thin roll rice.

[0018] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. Like reference numerals throughout the specification denote like elements.

[0019] The terms used herein are for the purpose of describing embodiments and are not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise. The words "comprise" and / or "comprising" as used herein do not exclude the presence or addition of one or more other components, steps, operations, and / or elements mentioned.

[0020] Hereinafter, the configuration and operation effects of the present invention will be described in more detail with reference to the attached drawings.

[0021] FIG. 1 is a schematic drawing illustrating a roll rice manufacturing device (100) according to one embodiment of the present invention, FIG. 2 is an exploded drawing schematically illustrating a roll rice manufacturing device (100) according to one embodiment of the present invention, FIG. 3 is a perspective view illustrating a main part of a roll rice manufacturing device (100) according to one embodiment of the present invention, FIG. 4 is a cross-sectional view illustrating a main part of a roll rice manufacturing device (100) according to one embodiment of the present invention, and FIG. 5 is a drawing illustrating a form in which food ingredients are combined inside a roll rice.

[0022] Fig. 5 is a drawing illustrating a form in which ingredients (13) are combined inside a rolled rice (10). It can be seen that the rolled rice (10) is formed in a circular tube shape overall, has a hollow portion (11) inside, and has a heating curing surface (12) provided on the inner and outer sides thereof.

[0023] Rice is located inside the heating curing screen (12), and since the heating curing screen (12) blocks air from entering, the distribution period can be dramatically increased.

[0024] In addition, when a food ingredient (13) with a lot of moisture is inserted into the cavity (11), as the moisture of the food ingredient (13) penetrates into the inside of the heat-curing surface, the hardened rice becomes soft, thereby realizing a soft texture. In one embodiment, when a food ingredient (13) with a lot of moisture is inserted into the inner cavity (11) of a rolled rice (10) and seaweed (14) is combined and rolled on the outer surface of the rolled rice (10), a texture similar to kimbap can be realized. In the process of manufacturing kimbap, the processes of spreading rice on each sheet of seaweed and placing ingredients on it are processes that can only be performed by hand. However, when the rolled rice manufacturing device (100) according to one embodiment of the present invention is utilized, the rolled rice manufacturing process can be automated, and the process of putting ingredients into the inside of the rolled rice manufactured in this way and the process of combining seaweed on the outer surface of the rolled rice can be automated, thereby automating and improving the efficiency of the kimbap manufacturing process.

[0025] A roll rice manufacturing device (100) according to one embodiment of the present invention includes a housing (120), an outer heating unit (130), a first heating unit (140), a transport unit (150), and a second heating unit (160). Furthermore, a support (110) for supporting the housing (120), the transport unit (150), etc., a driving means (180) for rotating the transport unit (150), etc. may be further included in the roll rice manufacturing device (100).

[0026] In one embodiment, the housing (120) may include a first body (121), a second body (122), and an inclined portion (123). The internal structures of the first body (121) and the second body (122) may have a cylindrical shape. At this time, the inner cylindrical diameter of the first body (121) may have a first diameter, and the inner cylindrical diameter of the second body (122) may have a second diameter, and the second diameter may be formed to be smaller than the first diameter. At this time, an inclined portion (123) may be provided between the first body (121) and the second body (122).

[0027] In one embodiment, the first body (121) may be provided with a material supply unit (124). Rice may be fed into the housing (120) through this material supply unit (124).

[0028] Although not shown, in one embodiment, the first body (121) may have a conical internal structure. In this case, the inclined portion (123) and the first body (121) may be formed continuously and integrally. In this case, the inner diameter of the conical internal structure may decrease toward the outer heating portion (130), but the change in diameter does not necessarily have to be linear.

[0029] In one embodiment, an outer surface heating unit (130) is provided on one side of the second body (122), and the outer surface heating unit (130) may have a cylindrical shape. In one embodiment, the first heating unit (140) may perform a function of providing heat to the outer surface heating unit (130). In one embodiment, the first heating unit (140) may be coupled to the outer surface of the outer surface heating unit (130).

[0030] In one embodiment, the transfer unit (150) is provided inside the housing (120) and the outer surface heating unit (130), and moves the rice inside the housing (120) forward in a first direction by a rotational motion. Here, the first direction may mean a direction from the housing (120) toward the outer surface heating unit (130). Meanwhile, when the transfer unit (150) rotates in reverse, the material inside the housing (120) may be transferred in a second direction opposite to the first direction. In one embodiment, the transfer unit (150) may include a first screw (151), a second screw (152), and an inner surface heating unit (153). In one embodiment, the first screw (151) may be located inside the first body (121), and the second screw (152) may be located inside the second body (122) and the outer surface heating unit (130). In addition, since the first screw (151) and the second screw (152) are positioned inside the housing (120), they can be configured to correspond to the size and shape of the housing (120). For example, when the inner cylindrical diameter of the first body (121) has a first diameter and the inner cylindrical diameter of the second body (122) has a second diameter, the first screw (151) can have a diameter slightly smaller than the first diameter, and the second screw (152) can have a diameter slightly smaller than the second diameter. In one embodiment, the inner side heating unit (153) can be provided on one side of the second screw (152) and can be implemented in a smooth cylindrical shape without a screw. In one embodiment, the transport unit (150) may include a first gear (154), which is connected to a driving means (180) and may perform a function of receiving rotational force from the driving means (180) to rotate the transport unit (150). Here, the driving means (180) may include a motor (181) having a second gear (182), and a power transmission belt (183) connected between the first gear (154) and the second gear (182).Meanwhile, referring to FIG. 3, the power transmission belt (183) may be implemented in a chain manner, and the first gear (154) may be coupled to at least one of the transfer unit (150) and the bobbin (164).

[0031] In one embodiment, the second heating unit (160) may be inserted into the transfer unit (150) and may perform a function of generating heat. In one embodiment, the second heating unit (160) may include a heating wire. At this time, the second heating unit (160) may include a first heating unit (161), a second heating unit (162), a wire receiving unit (163), and a connector (165). In one embodiment, the first heating unit (161) may be provided at a position corresponding to the inner heating unit (153), and the second heating unit (162) may be provided at a position corresponding to the second screw (152). At this time, the temperatures of the first heating unit (161) and the second heating unit (162) may be implemented differently. For example, the temperature of the second heating unit (162) may be set to be lower than the temperature of the first heating unit (161). Accordingly, as the rice is excessively heated while in contact with the second screw (152), the moisture content of the rolled rice becomes low, and as a result, the phenomenon of the rice hardening and clogging between the transport unit (150) and the outer heating unit (130) is alleviated, while the rolled rice discharged to the outside of the outer heating unit (130) can be sufficiently heated by the relatively high temperature of the second heating unit (162).

[0032] In one embodiment, electric heating elements such as heating wires and carbon heating elements are concentratedly arranged inside the first heating element (161) and the second heating element (162), and only power lines can be accommodated in the wire receiving portion (163). In another embodiment, some electric heating elements may also be arranged in the wire receiving portion (163) as needed.

[0033] In one embodiment, a connector (165) may be provided on the other side of the wire receiving portion (163). The second heating portion (160) must be coupled to the transfer unit (150) and transfer heat to the surface of the transfer unit (150). To this end, the second heating portion (160) must rotate together with the transfer unit (150), so that external power can be smoothly supplied to the power line provided inside the second heating portion (162), while preventing the power line and the external power from becoming tangled. To this end, the connector (165) may be formed in a ring shape, and the terminals (171-1, 171-2, 171-3, 171-4) may have a structure in which they contact the surface of the connector (165), but the contact between the surface of the connector (165) and the terminals is maintained even when the connector (165) is rotated.

[0034] In one embodiment, the connector (165) may be provided on the surface of the bobbin (164), and a plurality of connectors (165-1, 165-2, 165-3, 165-4) that are insulated from each other may be provided on the surface of the bobbin (164) as illustrated in FIGS. 1 to 4. At this time, a through hole (164-1) is formed on the inside of the bobbin (164), and a power line provided to the first heating unit (140) is positioned inside the through hole (164-1), and the power line may be electrically connected to each of the plurality of connectors (165-1, 165-2, 165-3, 165-4). In the drawing, four connectors (165-1, 165-2, 165-3, 165-4) are illustrated, but the number of connectors may vary as needed.

[0035] In one embodiment, a power line connected to a heating wire may be connected to the first connector (165-1) and the second connector (165-2), and a temperature sensor signal line may be connected to the third connector (165-3) and the fourth connector (165-4). Accordingly, it is possible to detect in real time whether the temperature of the second heating unit (160) is maintained within an appropriate temperature range, and the temperature of the second heating unit (160) may be controlled in real time using the temperature detection result. In one embodiment, a controller (173) connected to the first to fourth terminals (171-1, 171-2, 171-3, 171-4) by means of a wire (172) may detect the temperature of the second heating unit (160) and perform the function of maintaining an appropriate temperature. In addition, although not shown, the controller (173) may be electrically connected to the first heating unit (140), the motor (181), etc. to perform temperature control and rotation speed control.

[0036] In another embodiment, a first heating wire may be connected to the first connector (165-1) and the second connector (165-2), and a second heating wire may be connected to the third connector (165-3) and the fourth connector (165-4). At this time, the first heating wire may be arranged in the first heating unit (161), and the second heating wire may be arranged in the second heating unit (162). In addition, although not shown, a separate temperature sensor and a temperature sensor signal line for temperature detection may be further provided. Accordingly, the temperatures of the first heating unit (161) and the second heating unit (162) can be checked and controlled, respectively. Meanwhile, temperature sensors are respectively provided at positions far from the boundaries of the first heating unit (161) and the second heating unit (162), and thus, the independent temperatures of the first heating unit (161) and the second heating unit (162) can be measured more precisely.

[0037] Referring to FIGS. 3 and 4, a connecting bolt (166) can be fastened to a bobbin (164), and the lower portion of the connecting bolt (166) can be electrically connected to a connector (165) by a connecting wire (167). In addition, a wire passing through the through hole (164-1) can contact the upper portion of the connecting bolt (166). Accordingly, an electrical connection between the wire and the connector (165) can be realized. In addition, when the first to fourth connectors (165-1, 165-2, 165-3, 165-4) are provided on the bobbin (164), the connecting bolt (166) is also provided with the first to fourth connecting bolts (166-1, 166-2, 166-3), so that individual electrical connections can be implemented with the first to fourth connectors (165-1, 165-2, 165-3, 165-4) by the first to fourth connecting lines (167-1, 167-2, 167-3).

[0038] In one embodiment, a contact terminal that contacts the outer surface of each connector (165) may be provided, and the contact terminal may be connected to the controller (173) described above. At this time, the contact terminal may include a first contact terminal (178) and a second contact terminal (179). In addition, the first contact terminal (178) may be coupled to the other side of the first finger (175), and the second contact terminal (179) may be coupled to the other side of the second finger (176). Here, one side of the first finger (175) and one side of the second finger (176) are rotatably connected to the guide rod (174), and an elastic means (177) may be provided that presses the first finger (175) and the second finger (176) in a direction in which the distance between the one side of the first finger (175) and the other side of the second finger (176) becomes closer. Accordingly, the first contact terminal (178) and the second contact terminal (179) come into pressurized contact with the connector (165), so that electric energy and signals can be smoothly transmitted.

[0039] In one embodiment, the contact terminal may be made of a material having a lower hardness than the connector (165). Accordingly, the wear of the contact terminal may be greater than that of the connector (165) during the process of repeatedly rotating the connector (165) while the contact terminal is in contact with the connector (165). In an extreme case, the connector (165) may be hardly worn out and only the contact terminal may be worn out. While the contact terminal can be easily attached and detached from the first finger (175), the connector (165) may be relatively less convenient to detach and attach to the bobbin (164). By making the contact terminal more easily worn out, the replacement cycle of the connector (165) can be lengthened, while the replacement cycle of the easy-to-replace contact terminal can be relatively shortened.

[0040] While representative embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that various modifications to the above-described embodiments are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims set forth below but also by equivalents thereof.

[0041] By utilizing the roll rice manufacturing device of the present invention, the roll rice manufacturing process can be automated and made more efficient, and thus can be utilized in fields such as food processing and the restaurant industry that require mass production and quality maintenance.
