Background Technology

[0002] In general, technology for quantitatively filling liquid or semi-liquid raw materials is widely used in various industrial fields, such as food, cosmetics, pharmaceuticals, and chemical processes. In particular, in food manufacturing processes, it is essential to fill raw materials with viscosity or those mixed with solids—such as rice, dough, sauces, and toppings—in a fixed volume.

[0003] However, since most conventional filling devices were designed for liquid-based materials, smooth transfer and filling were difficult for materials with high viscosity or those containing particles.

[0004] In particular, when manufacturing food products such as fried tofu sushi, it is necessary to stably place solid materials, such as toppings, on top of the rice while keeping the internal space of the fried tofu open, but with existing filling devices, it was difficult to fill the inside of the fried tofu with the correct quantity and position of the topping materials.

Brief explanation of the drawing

[0016] FIG. 1 is a drawing showing a quantitative filling system for raw materials containing solids according to the present invention. Specific details for implementing the invention

[0017] Hereinafter, preferred embodiments of the quantitative filling system and method for raw materials containing solids according to the present invention will be described in detail with reference to the attached drawings.

[0019] The quantitative filling system for raw materials containing solids according to the present invention comprises: a hopper (100) that accommodates raw materials containing solids and is configured such that the cross-sectional area narrows as it extends downward; a first body part (200) located below the hopper (100), formed in a columnar shape, and having a first-1 space (201) provided inside; a first rotating part (210) located in the first-1 space (201), rotatably configured inside the first body part (200), and having a first-2 space (211) provided inside to accommodate the raw materials transported from the hopper (100); a first driving part (220) located in the first body part (200), which rotates the first rotating part (210) and transports the raw materials through the first-2 space (211); and a columnar shape located on one side of the first body part (200). It is composed of a second body part (300) formed and having a second-1 space (301), a second rotating part (310) located in the second-1 space (301) and rotatably provided inside the second body part (300) and having a second-2 space (311) provided inside to receive the raw material transferred from the first rotating part (210), a second driving part (320) located in the second body part (300) and rotating the second rotating part (310) and transferring the raw material through the second-2 space (311), a supply part (400) provided below the second body part (300) and discharging the raw material, and a control part (500) that operates the first driving part (220), the second driving part (320), and the supply part (400).

[0021] First, a hopper (100) is provided in the quantitative filling system for raw materials containing solids according to the present invention. The hopper (100) is formed with a structure that is open at the top to receive raw materials introduced from the outside, and has a sloping structure in which the cross-sectional area narrows as it goes downward, so that the raw materials can be smoothly transported downward by gravity.

[0022] In addition, the hopper (100) may be further provided with a vibrating part (not shown) or a coating layer (not shown) on its inner surface to improve the transportability of high-viscosity raw materials.

[0024] Here, the above raw material may be a composition in which a solid is mixed with a liquid component; for example, in the process of manufacturing fried tofu sushi, it may be a raw material having viscosity, such as a topping mixed with vegetables, seafood, etc. The transport characteristics of the above raw material may vary depending on the size and type of solid particles and the ratio and type of liquid components.

[0026] A first body part (200) is provided below the hopper (100). The first body part (200) is formed in a column shape and has a first-1 space (201) provided inside. The upper part of the first body part (200) is connected to the outlet of the hopper (100).

[0027] The above-mentioned first-1 space (201) is formed as a space in which the first rotating part (210), which will be described below, is rotatably arranged, and has a sufficient size and shape so that the rotational operation of the first rotating part (210) can be performed smoothly.

[0029] A first rotating part (210) is provided in the first-1 space (201). The first rotating part (210) is rotatably provided inside the first body part (200), and a first-2 space (211) is provided inside the first rotating part (210) to accommodate the raw material transported from the hopper (100). Here, it is preferable that the first-2 space (211) be formed in a column shape.

[0030] As the first rotating part (210) rotates, the first-second space (211) can receive the raw material transferred from the hopper (100) when it is connected to the outlet of the hopper (100), and the raw material can be transferred to one side when the first-second space (211) is connected to one side of the first body part (200).

[0031] Additionally, the first-second space (211) of the first rotating part (210) may be formed as a replaceable structure so that its size and shape can be adjusted according to the type of raw material, viscosity, particle size of the solid material, and filling capacity. The first body part (200) and the first rotating part (210) may be configured as an integrated module so that the entire first body part (200) can be separated and replaced, and the first body part (200) may be formed to be separated so that the first rotating part (210) can be replaced.

[0033] A first driving unit (220) is provided in the first body part (200). The first driving unit (220) rotates the first rotating part (210) to control the first-second space (211) to selectively communicate with the hopper (100) or one side of the first body part (200). Accordingly, when the first-second space (211) is connected to one side of the first body part (200), the first driving unit (220) transports the raw material through the first-second space (211).

[0034] In addition, the first driving unit (220) can adjust the discharge pressure and discharge speed according to the viscosity of the raw material and the particle size of the solid.

[0036] A second body part (300) is provided in communication with one side of the first body part (200). The second body part (300) is formed in a column shape and a second-1 space (301) is provided inside.

[0037] The above 2-1 space (301) is formed as a space in which the second rotating part (310), which will be described below, is rotatably arranged, and has a sufficient size and shape so that the rotational operation of the second rotating part (310) can be performed smoothly.

[0039] A second rotating part (310) is provided in the second-1 space (301). The second rotating part (310) is rotatably provided inside the second body part (300), and a second-2 space (311) is provided inside the second rotating part (310) to accommodate the raw material transported from the first-2 space (211) of the first rotating part (210). Here, it is preferable that the second-2 space (311) be formed in a column shape.

[0040] As the second rotating part (310) rotates, if the second-2 space (311) is connected to the first-2 space (211), it can receive the raw material transferred from the first-2 space (211), and if the second-2 space (311) is connected to the lower part of the second body part (300), the raw material can be discharged to the lower part of the second body part (300).

[0041] Additionally, the second-2 space (311) of the second rotating part (310) may be formed as a replaceable structure so that its size and shape can be adjusted according to the type of raw material, viscosity, particle size of the solid material, and filling capacity. The second body part (300) and the second rotating part (310) may be configured as an integrated module so that the entire second body part (300) can be separated and replaced, and the second body part (300) may be formed to be separated so that the second rotating part (310) can be replaced.

[0043] A second driving unit (320) is provided in the second body part (300). The second driving unit (320) rotates the second rotating unit (310) to control the second-2 space (311) to selectively communicate with the first-2 space (211) or the lower part of the second body part (300). Accordingly, when the second-2 space (311) is connected to the lower part of the second body part (300), the second driving unit (320) transports the raw material through the second-2 space (311).

[0044] In addition, the second driving unit (320) can adjust the discharge pressure and discharge speed according to the viscosity of the raw material and the particle size of the solid.

[0046] A supply unit (400) is provided below the second body part (300). The supply unit (400) discharges the raw material contained in the second-2 space (311). Specifically, when the second rotating part (310) rotates, the second-2 space (311) and the supply unit (400) are connected. Accordingly, the raw material located in the second-2 space (311) is discharged through the supply unit (400).

[0047] The supply unit (400) is formed with an open upper structure to accommodate the raw material introduced from the second-2 space (311), and has a sloping structure in which the cross-sectional area narrows as it goes downward, so that the raw material can be smoothly transported downward by gravity. In addition, a coating layer (not shown) may be further provided on the inner surface of the supply unit (400) to improve the transportability of high-viscosity raw materials.

[0048] An opening (410) is further provided in the supply unit (400). The opening (410) is rotatably installed on the outer surface of the supply unit (400) so as to be opened to the outside of the supply unit (400) or folded as needed.

[0049] In the method for manufacturing fried tofu sushi, when only rice is filled inside the fried tofu, there is a problem in that it is difficult to stably fill the above-mentioned ingredients used as toppings because the fried tofu is folded. At this time, when the opening (410) is rotated in the forward direction to open, the upper part of the folded fried tofu opens up, securing an internal space and thus securing a space to fill the above-mentioned ingredients. In addition, the opening (410) may also serve as a barrier to prevent the above-mentioned ingredients from scattering or leaking out.

[0050] And, when the opening (410) is rotated in the reverse direction and folded, the raw material remaining in the supply part (400) can be discharged by the impact generated as the supply part (400) and the opening part (410) collide with each other.

[0051] Additionally, the opening (410) is provided to be movable in the up and down direction, so that after the raw material is filled, it moves downward to press the raw material on the upper part of the fried tofu sushi. At this time, due to the pressing action by the opening (410), the raw material is more densely fixed inside the fried tofu, and the surface of the raw material is flattened to form an aesthetically pleasing appearance.

[0053] A control unit (500) is provided to operate the opening (410) of the first driving unit (220), the second driving unit (320), and the supply unit (400). The control unit (500) controls the driving signals of the first driving unit (220), the second driving unit (320), and the opening (410) so that the filling process of the raw material proceeds sequentially.

[0054] The control unit (500) drives the first drive unit (220) to rotate the first rotation unit (210), thereby causing the first-second space (211) to be in communication with the hopper (100). Subsequently, the control unit (500) operates the first drive unit (220) to rotate the first rotation unit (210) and operates the second drive unit (320) to rotate the second rotation unit (310), thereby causing the first-second space (211) and the second-second space (311) to be in communication. The control unit (500) operates the first drive unit (220) to transfer the raw material contained in the first-second space (211) to the second-second space (311).

[0055] In addition, the control unit (500) rotates the opening (410) of the supply unit (400) in the forward direction to open it and secure the internal space of the unit.

[0056] After that, the control unit (500) operates the first drive unit (220) and the second drive unit (320) to rotate the first rotation unit (210) and the second rotation unit (310) so that the second-second space (311) and the supply unit (400) are connected. The control unit (500) drives the second drive unit (320) to control the raw material contained in the second-second space (311) to be discharged through the supply unit (400). When the raw material filling process is completed, the control unit (500) controls the opening unit (410) to rotate in the reverse direction and fold it so that the remaining raw material in the supply unit (400) can be discharged.

[0057] Accordingly, the control unit (500) controls the operation of the first driving unit (220), the second driving unit (320), and the opening unit (410) in an integrated manner, thereby enabling stable quantitative filling of raw materials having viscosity or containing solids.

[0058] Additionally, the control unit (500) can adjust the discharge pressure or speed of the first driving unit (220) and the second driving unit (320) according to the viscosity of the raw material and the particle size of the solid material. Specifically, when the viscosity of the raw material is low, the discharge pressure is lowered and the discharge speed is maintained at a constant medium level so that the raw material is filled uniformly without scattering. On the other hand, in the case of a raw material with high viscosity or a raw material with a large particle size, the discharge pressure is increased and the discharge speed is lowered so that the raw material is transported without clogging. In the case of a raw material with medium viscosity, the discharge pressure and discharge speed are maintained at a constant medium level so that the raw material is filled uniformly without overfilling or residue.

[0059] In addition, for raw materials with small particle sizes, the discharge pressure and discharge speed are lowered to prevent scattering or uneven discharge. In cases where the particle size is irregular or there is a concern about clogging depending on the mixing ratio, the control unit (500) applies a pulse control method that changes the discharge pressure and speed, so that the high pressure / high speed state and the low pressure / low speed state can be filled repeatedly at a certain interval.

[0060] Therefore, by controlling not only the discharge pressure but also the speed, raw materials with various viscosities and particle sizes can be stably and quantitatively filled.

[0062] The quantitative filling device for raw materials containing solids according to the present invention has been described with reference to an embodiment in which the first body part (200) and the second body part (300) are each formed in a single stage, but is not limited thereto. If necessary, the first body part (200) and the second body part (300) may be arranged in multiple stages, and in this case, it is possible to transport and fill raw materials sequentially to precisely fill a larger volume of raw materials or to fill multiple types of raw materials in stages.

[0064] Hereinafter, a quantitative filling method for a raw material containing solids according to the present invention will be described.

[0066] In the first step, the type of raw material is selected, and information about the raw material is stored in the control unit (500). Specifically, the user can select the viscosity of the raw material to be input and the particle size of the solid material, and the viscosity can be classified into high viscosity, medium viscosity, and low viscosity, and the particle size of the solid material can be classified into large, small, and non-uniform, but is not limited thereto.

[0067] Information regarding the viscosity and particle size of the solid selected in the control unit (500) can be stored, and the discharge pressure and discharge speed of the first drive unit (220) and the second drive unit (320) can be automatically controlled according to the information. Additionally, the user can directly set the discharge pressure and discharge speed of the first drive unit (220) and the second drive unit (320) as needed.

[0069] In the second step, as illustrated in A of FIG. 1, the first driving unit (220) is operated by the control unit (500) to rotate the first rotating unit (210) so that the hopper (100) and the first-second space (211) are connected. At this time, the raw material contained in the hopper (100) flows into the first-second space (211) by the action of gravity, and if necessary, even high-viscosity materials can be smoothly transported by the action of the vibrating unit or internal coating layer provided in the hopper (100).

[0071] In the third step, as illustrated in Fig. 1B, when raw materials introduced from the hopper (100) are received in the first-second space (211), the control unit (500) rotates the first rotating unit (210) and the second rotating unit (310). Specifically, the control unit (500) operates the first driving unit (220) to rotate the first rotating unit (210) and operates the second driving unit (320) to rotate the second rotating unit (310). At this time, the first-second space (211) and the second-second space (311) are connected.

[0073] The fourth step, as illustrated in Fig. 1B, involves operating the first driving unit (220) in the control unit (500) to transfer the raw material contained in the first-2 space (211) to the second-2 space (311). At this time, the control unit (500) adjusts the discharge pressure and speed of the first driving unit (220) according to the viscosity of the raw material and the particle size of the solid material so that the raw material is transferred smoothly without clogging.

[0075] Step 5 involves rotating the opening (410) in the control unit (500) to open it, as illustrated in Fig. 1B. Specifically, when the opening (410) is rotated in the forward direction to open, the upper part of the oil container opens up, forming a space for filling the raw material.

[0077] Step 6 involves rotating the first rotating part (210) and the second rotating part (310) in the control unit (500), as illustrated in C of FIG. 1. Specifically, the control unit (500) operates the first driving unit (220) to rotate the first rotating part (210) and operates the second driving unit (320) to rotate the second rotating part (310). At this time, the second-2 space (311) is connected to the supply unit (400).

[0079] Step 7 involves operating the second driving unit (320) in the control unit (500) to discharge the raw material contained in the second-2 space (311), as illustrated in C of FIG. 1. The raw material is discharged to the upper part of the oil through the supply unit (400). At this time, the opening (410) prevents the raw material from scattering or leaking out during the filling process.

[0080] In addition, the control unit (500) adjusts the discharge pressure and speed of the second drive unit (320) according to the viscosity of the raw material and the particle size of the solid material so that the raw material is transported smoothly without clogging.

[0081] In addition, the control unit (500) moves the opening (410) downward to press the raw material, thereby fixing the raw material densely and smoothing the surface.

[0083] Step 8, as illustrated in Fig. 1C, raises the opening (410) in the control unit (500) and then rotates it to discharge the raw material remaining in the second-2 space (311) and the supply unit (400). Specifically, during the process of rotating the opening (410) in the reverse direction, the remaining raw material is discharged due to the impact caused by the collision between the supply unit (400) and the opening (410).

[0085] Step 9 repeats Steps 3 through 8 above. Through this, the process of sequentially receiving, transporting, filling, and discharging raw materials is carried out continuously, allowing for the repeated performance of a stable and quantitative filling process for various raw materials.

[0087] As such, those skilled in the art to which the present invention pertains will understand that the technical configuration of the present invention described above can be implemented in other specific forms without changing the technical concept or essential features of the present invention.
