Description

Technical Field

[0001] This invention relates to a kitchen waste treatment device and treatment method. Background Technology

[0002] Food waste treatment equipment processes food waste by heating and drying it to remove moisture and reduce its volume.

[0003] When processing this type of food waste, the food waste is heated in a drying furnace. In order to prevent the gas generated during the heating process from causing a pressure rise, the gas is discharged to the outside.

[0004] When the gas is discharged to the outside, it is filtered to remove odors, but because the odors are not actually completely removed, an unpleasant smell is generated around the food waste treatment unit. Summary of the Invention

[0005] (Technical issue)

[0006] The present invention is proposed to solve the above-mentioned problems, and its purpose is to provide a kitchen waste treatment device and method that treats kitchen waste without emitting gas.

[0007] (Technical Solution)

[0008] To achieve the above objectives, the food waste treatment apparatus according to the present invention includes: a drying furnace for feeding food waste and heating it; a gas flow pipe connected to the drying furnace, wherein gas from the drying furnace flows; and a pressure regulating unit connected to the gas flow pipe, having a pressure regulating space whose size can be varied by the inflow and outflow of the gas.

[0009] As an example, the pressure regulating unit can be configured as a foldable structure.

[0010] As another example, the pressure regulating unit can be formed of a flexible material.

[0011] The pressure regulating unit includes: a pressure regulating cylinder, one side of which is connected to the gas flow pipe and the other side is open; and a movable partition disposed inside the pressure regulating cylinder, forming the pressure regulating space between the partition and one side of the pressure regulating cylinder; the movable partition moves to one side or the other side of the pressure regulating cylinder according to the pressure of the gas in the pressure regulating space, thereby adjusting the size of the pressure regulating space.

[0012] The present invention further includes: a gas circulation pipe connected to the drying oven, wherein the gas discharged from the drying oven circulates therein; the gas flow pipe may be directly connected to the drying oven, or may be connected to the drying oven through the gas circulation pipe.

[0013] Alternatively, the pressure regulating unit can be a water bucket connected to the lower part of the gas circulation pipe.

[0014] The invention may further include: a water tank connected to the lower part of the gas circulation pipe; and a cooling unit for cooling the gas to remove moisture from the gas circulating in the gas circulation pipe.

[0015] The cooling unit may include: a condenser for condensing refrigerant; and a cooling pipe connected to the condenser for the refrigerant to flow through, and disposed in the gas circulation pipe.

[0016] The gas circulation pipe has a spiral circulation section, and the cooling unit can be a cooling fan that cools the spiral circulation section with air.

[0017] The gas circulation pipe has a connection portion that connects to the water bucket, and the lower part of the gas circulation pipe can be configured to slope downwards towards the connection portion.

[0018] The gas circulation pipe may have a first connection portion connected to one side of the water bucket and a second connection portion connected to the other side of the water bucket.

[0019] The gas circulation pipe has a gas inlet end into which the gas flows into the drying furnace, and a gas outlet end into which the gas flows out again into the drying furnace. The gas outlet end may be configured lower than the gas inlet end within the drying furnace.

[0020] The present invention further includes: a crushing blade and a stirring blade disposed within the drying oven; a drive motor for rotating the crushing blade and the stirring blade; a blade connecting unit for connecting the crushing blade and the drive motor; and a blade connecting unit for connecting the stirring blade and the drive motor; wherein the blade rotation shaft of the blade connecting unit passes through the blade rotation shaft of the blade connecting unit, and the blade rotation shaft and the blade rotation shaft may be composed of a dual-axis structure that rotates independently of each other.

[0021] The tool rotation axis and the blade rotation axis can rotate in opposite directions.

[0022] The cutter connecting unit includes a cutter rotating shaft connected to the crushing cutter, the cutter rotating shaft being connected to the motor shaft of the drive motor. The blade connecting unit includes a blade rotating shaft connected to the stirring blade, and a driven gear is formed on the blade rotating shaft, the driven gear being able to mesh with the drive gear formed on the motor shaft.

[0023] In order to make the stirring blades rotate at a lower speed than the crushing blades, the driven gear can be made larger than the driving gear.

[0024] The drive motor can be located on the side of the drying oven and configured in the vertical direction.

[0025] The tool connecting unit may also include a drive belt connecting the tool rotation shaft and the motor shaft.

[0026] The shredding blade may include: a plurality of brackets mounted at intervals between each other in the vertical direction on the blade rotation axis; and a plurality of cutting members mounted at intervals between each other along the respective edges of the plurality of brackets.

[0027] The cutting component and the stirring blade can each be bent in the direction of rotation.

[0028] The cutting tool rotation axis and the blade rotation axis rotate in opposite directions, and the cutting component and the stirring blade can be bent in opposite directions.

[0029] According to another aspect of the present invention, a method for treating food waste can be provided, comprising: a heating step for heating food waste fed into a drying oven; a cooling step for cooling the food waste after the heating treatment is completed; and a pressure regulating step in which, while blocking the discharge of gas to the outside, the size of the pressure regulating space connected to the pressure regulating unit of the drying oven is changed by the inflow and outflow of gas into the pressure regulating space during the heating step and the cooling step.

[0030] The pressure regulation step may include: a first pressure regulation step, in which, during the heating step, the size of the pressure regulation space increases when the gas flows from the drying oven into the pressure regulation unit; and a second pressure regulation step, in which, during the cooling step, the size of the pressure regulation space decreases when the gas flows from the pressure regulation unit out of the drying oven.

[0031] (Invention Effects)

[0032] The present invention constitutes a pressure regulating unit in which the size of the pressure regulating space can be varied by the inflow and outflow of gas, thereby maintaining the pressure of the drying oven within a stable range even if the gas with odor is not discharged from the drying oven to the outside.

[0033] Furthermore, the present invention does not regulate the internal pressure of the drying oven through individual components such as measuring sensors and switching valves, but rather through automatic regulation by a pressure regulating unit, thus avoiding the problems caused by individual component failures.

[0043] Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily implement the present invention. However, in describing the preferred embodiments in detail, if it is determined that a detailed description of a related known function or structure may unnecessarily obscure the gist of the present invention, such detailed description will be omitted. Furthermore, for parts with similar functions and effects, the same reference numerals are used throughout the drawings. Additionally, in this specification, terms such as "upper," "upper part," "above," "lower," "lower part," "below," and "side" are based on the drawings and may actually vary depending on the orientation of the component arrangement.

[0044] Furthermore, throughout the specification, when a part is "connected" to another part, this includes not only "direct connection" but also "indirect connection" with other components in between. Moreover, "including" a part, unless specifically stated otherwise, does not mean excluding other parts, but rather that other parts may be further included.

[0045] Figures 1 to 5 This is a diagram illustrating a food waste treatment apparatus according to the first to fifth embodiments of the present invention.

[0046] Reference Figures 1 to 5 According to the first to fifth embodiments of the present invention, the kitchen waste treatment device includes a drying furnace 100, a gas flow pipe 200, and a pressure regulating unit 300.

[0047] The drying furnace 100 is a receiving component for feeding and heating kitchen waste.

[0048] Specifically, the drying oven 100 has an internal space of a certain size so as to be able to accommodate a certain amount of food waste.

[0049] The drying oven 100 is equipped with a rotating component (not shown) to perform stirring or pulverizing operations on food waste. In this case, the rotating component only needs to be configured to stir or pulverize the food waste, and is not limited to the present invention.

[0050] Meanwhile, a heater 110 is installed inside the drying oven 100, which can simultaneously perform drying operations while crushing and mixing kitchen waste.

[0051] The drying oven 100 only needs to be configured to stably heat and process kitchen waste, and its specific structure is of course not limited by the present invention.

[0052] In addition, the gas flow pipe 200 is connected to the drying oven 100 and is a pipe through which the gas in the drying oven 100 flows.

[0053] This gas flow tube 200 can have, for example, Figures 1 to 4 The first to fourth embodiments shown are connected to the drying oven 100 via a gas circulation pipe 400, or can be as follows: Figure 5 The fifth embodiment shown is directly connected to the drying oven 100.

[0054] Furthermore, the pressure regulating unit 300 is connected to the gas flow pipe 200, thereby allowing the gas from the drying oven 100 to flow into the pressure regulating unit 300 through the gas flow pipe 200.

[0055] The pressure regulating unit 300 regulates the pressure inside the drying oven 100 while blocking the gas from being discharged from the drying oven 100 to the outside of the device.

[0056] During the process of heating and drying food waste in the drying oven 100, gas is generated from the food waste, and the pressure inside the drying oven 100 will increase due to this gas.

[0057] Existing food waste treatment devices are configured to vent gas to the outside to reduce increased internal pressure. Simultaneously, filters are used to remove odors from the vented gas; however, due to filter performance limitations and frequent replacement cycles, odors are practically impossible to completely remove.

[0058] To overcome the above problems, the food waste treatment device according to the present invention comprises a pressure regulating unit 300 connected to the drying furnace 100.

[0059] The pressure regulating unit 300 is connected to the drying oven 100 through the gas flow pipe 200. At this time, the gas flow pipe 200 can be directly connected to the drying oven 100, or it can be connected to the drying oven 100 through the gas circulation pipe 400.

[0060] This pressure regulating unit 300 has a pressure regulating space 300a whose size is variable due to the inflow and outflow of gas. That is, the pressure regulating unit 300 can have a pressure regulating space 300a that can expand and contract due to the inflow and outflow of gas.

[0061] In other words, a pressure regulating space 300a is formed inside the pressure regulating unit 300. This pressure regulating space 300a can have an expandable and contractible structure, so that the gas that generates high pressure in the drying oven 100 can flow out after flowing into the interior.

[0062] During the process of heating and drying food waste in the drying oven 100, the internal temperature of the drying oven 100 rises and gas is generated, causing the internal pressure to rise accordingly. Therefore, the pressure regulating space 300a of the pressure regulating unit 300 expands due to the inflow of a certain amount of gas discharged from the drying oven 100 through the gas flow pipe 200. Thus, the pressure regulating unit 300 can prevent the internal pressure of the drying oven 100 from rising.

[0063] After the heating and drying process of food waste is completed in the drying oven 100, the internal temperature of the drying oven 100 drops, and the moisture in the gas is collected in the water tank 500, thus causing a decrease in the internal pressure of the drying oven 100. Therefore, the pressure regulating space 300a of the pressure regulating unit 300 contracts as a certain amount of gas contained therein flows out to one side of the drying oven 100 through the gas flow pipe 200. Thus, the pressure regulating unit 300 can prevent a decrease in the internal pressure of the drying oven 100.

[0064] As described above, the present invention does not regulate the internal pressure of the drying oven 100 through individual components such as measuring sensors and switching valves, but rather through a pressure regulating unit 300 having a pressure regulating space 300a that expands and contracts due to the inflow and outflow of gas. Therefore, the present invention is also free from problems such as malfunctions of measuring sensors and valves.

[0065] As an example, such as Figures 2 to 4 As shown, the pressure regulating unit 300 can be configured as a foldable structure so that the size of the pressure regulating space 300a is variable.

[0066] Thus, the pressure regulating unit 300 can adopt a structure in which at least part of it can be folded and overlapped, that is, the more it is unfolded, the larger the volume of the pressure regulating space 300a becomes, and the more it is folded, the smaller the volume of the pressure regulating space 300a becomes.

[0067] As another example, although not shown in the accompanying drawings, the pressure regulating unit 300 can be formed of a flexible material to make the size of the pressure regulating space 300a variable.

[0068] That is, the pressure regulating unit 300 can be made of a flexible material such as a balloon rubber.

[0069] As yet another example, such as Figure 5 As shown, the pressure regulating unit 300 may include a pressure regulating cylinder 310 and a movable partition 320.

[0070] The pressure regulating cylinder 310 can be configured with one side connected to the gas flow pipe 200 and the other side open. Furthermore, a movable partition 320 can be disposed within the pressure regulating cylinder 310, thereby forming a pressure regulating space 300a between the partition and one side of the pressure regulating cylinder 310.

[0071] That is, the movable partition 320 is disposed inside the pressure regulating cylinder 310 to form a pressure regulating space 300a inside the pressure regulating cylinder 310, thereby preventing the gas flowing into the pressure regulating space 300a through the gas flow pipe 200 from being discharged to the outside of the pressure regulating cylinder 310.

[0072] This movable baffle 320 can be moved to one side or the other side of the pressure regulating cylinder 310 by the pressure of the gas in the pressure regulating space 300a, thereby adjusting the size of the pressure regulating space 300a.

[0073] If gas flows into the pressure regulating space 300a, as the pressure of the gas in the pressure regulating space 300a increases, the movable baffle 320 will move to the other side of the pressure regulating cylinder 310, thereby causing the size of the pressure regulating space 300a to decrease.

[0074] Conversely, if gas flows out of the pressure regulating space 300a, as the pressure of the gas in the pressure regulating space 300a decreases, the movable partition 320 will move to one side of the pressure regulating cylinder 310, thereby causing the size of the pressure regulating space 300a to increase.

[0075] On the other hand, the present invention may also include a gas circulation pipe 400.

[0076] The gas circulation pipe 400 is connected to the drying oven 100, and adopts a structure in which the gas discharged from the drying oven 100 is circulated.

[0077] This gas circulation pipe 400 can be equipped with a circulating fan P for circulating gas and a filter F for filtering gas.

[0078] This gas circulation pipe 400 can be in the form of a pipe or tube, as long as it is configured to allow smooth circulation of the gas discharged from the drying oven 100. Its specific structure is of course not limited by the present invention.

[0079] like Figure 2 and Figure 4 As shown, in the food waste treatment apparatus of the second and fourth embodiments of the present invention, the pressure regulating unit 300 may be a water tank 500 connected to the lower part 400a of the gas circulation pipe 400.

[0080] like Figure 1 and Figure 3 As shown, in the food waste treatment devices of the first, third, and fifth embodiments of the present invention, the pressure regulating unit 300 can be separately configured from the water tank 500; unlike this, as Figure 2 and Figure 4 As shown, in the food waste treatment apparatus of the second and fourth embodiments of the present invention, the water tank 500 for collecting moisture contained in the gas can be used as a pressure regulating unit 300.

[0081] Right now, Figure 2 and Figure 4The water tank 500 shown adopts a folding structure that makes the size of the pressure regulating space 300a, which serves as the internal space, variable, so that it can become a pressure regulating unit 300. Thus, in addition to performing its original function of collecting the moisture contained in the gas, it can also regulate the internal pressure of the drying oven 100 by the inflow and outflow of gas.

[0082] Furthermore, the present invention, together with the water tank 500 connected to the lower part 400a of the gas circulation pipe 400, may also include a cooling unit 600.

[0083] That is, according to Figures 3 to 5 According to the third to fifth embodiments shown, the present invention may further include a cooling unit 600 for cooling the gas circulating in the gas circulation pipe 400.

[0084] The cooling unit 600 cools the gas circulating in the gas circulation pipe 400 and liquefies the moisture contained in the gas. The water formed by the liquefaction of moisture flows into the water tank 500 and is collected.

[0085] As an example, according to Figure 3 and Figure 4 The third and fourth embodiments of the present invention shown may include a cooling unit 600 that may include a condenser 610 and a cooling pipe 620.

[0086] The condenser 610 condenses the refrigerant, and its specific composition is not limited by the present invention; of course, any existing condensation structure can be used.

[0087] In addition, the cooling pipe 620 is connected to the condenser 610, through which the refrigerant condensed by the condenser 610 flows, and is installed in the gas circulation pipe 400 to cool the gas in the gas circulation pipe 400.

[0088] More specifically, the cooling pipe 620 can be disposed throughout the gas circulation pipe 400.

[0089] Thus, the cooling pipe 620 adopts a structure that spans a portion of the gas circulation pipe 400, thereby directly cooling the gas circulating in the gas circulation pipe 400, improving the cooling performance of the gas, and thus improving the drying efficiency of kitchen waste.

[0090] As another example, according to Figure 5 In the fifth embodiment of the present invention shown, the cooling unit 600 may be a cooling fan.

[0091] Specifically, the gas circulation pipe 400 may have a spiral circulation section 410, in which case the cooling unit 600 may be an air-cooled cooling fan for the spiral circulation section 410.

[0092] On the other hand, in order to improve the drying efficiency of kitchen waste, the gas circulation pipe 400 can adopt the following structure.

[0093] First, the gas circulation pipe 400 has a connection portion 430 that connects to the water tank 500. Here, the gas circulation pipe 400 can be configured such that the lower part 400a slopes downward towards the connection portion 430.

[0094] Specifically, the lower part 400a of the gas circulation pipe 400 can be taken as an example as follows: Figures 1 to 3 The shape shown is curved, or as another example, it can be as follows: Figure 4 As shown, it forms a linear inclined structure. At this time, as... Figure 3 and Figure 4 As shown, a portion 620a of the cooling pipe 620 disposed inside the lower part 400a of the gas circulation pipe 400 can be formed into a shape corresponding to the shape of the gas circulation pipe 400.

[0095] If the lower part of the gas circulation pipe is made horizontal, the water produced by liquefaction inside the gas circulation pipe may not flow to the bucket but instead accumulates.

[0096] In contrast, the present invention can employ a structure in which the lower part 400a of the gas circulation pipe 400 slopes downwards towards the connecting part 430. In this case, the water produced by liquefaction within the gas circulation pipe 400 will not accumulate in the gas circulation pipe 400, but can flow smoothly to the water tank 500.

[0097] Furthermore, as yet another example, the gas circulation pipe 400 can be as follows: Figure 1 and Figure 5 As shown, there are a first connecting portion 431 and a second connecting portion 432 arranged at intervals between each other.

[0098] The first connecting part 431 is connected to one side of the water tank 500, and the second connecting part 432 can be connected to the other side of the water tank 500. In this way, the first connecting part 431 and the second connecting part 432 are far apart from each other, thereby utilizing the structure of the gas circulating in the gas circulation pipe 400 to effectively pass through the interior of the water tank 500, thereby improving the drying rate of the gas.

[0099] In addition, the gas circulation pipe 400 may be formed with a gas inlet end 421 into which the gas generated in the drying furnace 100 flows in, and a gas outlet end 422 into which the inflowing gas flows out again into the drying furnace 100 after circulation.

[0100] Here, the gas inlet end 421 can be formed on the upper side of the drying furnace 100, and the gas outlet end 422 can be formed on the upper other side of the drying furnace 100.

[0101] As an example, such as Figure 5As shown, the gas outlet 422 can be configured lower than the gas inlet 421 within the drying furnace. Therefore, the gas flowing out through the gas outlet 422 and into the drying furnace 100 can push other gases (with high moisture content) or moisture inside the drying furnace 100 towards the gas inlet 421. In other words, because the gas outlet 422 is configured lower than the gas inlet 421, the drying efficiency of food waste in the drying furnace 100 can be improved.

[0102] The method for processing food waste using the food waste processing device configured as described above is as follows.

[0103] The food waste treatment method may include a heating step, a cooling step, and a pressure regulation step.

[0104] First, the heating step is the process of heating the kitchen waste that is fed into the drying furnace 100.

[0105] Then, the cooling step is the step of cooling the food waste after the heating treatment is completed.

[0106] On the other hand, the pressure regulation step can be performed during the heating and cooling steps while blocking the gas from being discharged to the outside.

[0107] The pressure regulation step is a step in which the size of the pressure regulation space 300a of the pressure regulation unit 300 connected to the drying oven 100 is changed by the inflow and outflow of gas into the pressure regulation space 300a.

[0108] Specifically, the pressure regulation step may include a first pressure regulation step and a second pressure regulation step.

[0109] The first pressure regulation step is a step in which the size of the pressure regulation space 300a increases when gas flows from the drying furnace 100 into the pressure regulation unit 300 during the heating step, so that the internal pressure of the drying furnace 100 is not too much higher than atmospheric pressure.

[0110] Furthermore, the second pressure regulation step is a step in which the size of the pressure regulation space 300a decreases when gas flows out of the pressure regulation unit 300 into the drying oven 100 during the cooling step, thereby adjusting the internal pressure of the drying oven 100 so that it is not too much lower than atmospheric pressure.

[0111] As a result, the present invention constitutes a pressure regulating unit 300 whose size can be varied by the inflow and outflow of gas, thereby maintaining the pressure of the drying oven 100 within a stable range even if the odorous gas is not discharged from the drying oven 100 to the outside.

[0112] Furthermore, the present invention does not regulate the internal pressure of the drying oven 100 by measuring sensors and switching valves, but automatically regulates it by the pressure regulating unit 300. Therefore, it is not limited by problems such as failure of individual components.

[0113] Figure 6 This is a diagram illustrating a food waste treatment apparatus according to a sixth embodiment of the present invention. Figure 7 It is shown Figure 6 A diagram showing the structure of the rotating shredder and mixing blades in a food waste treatment device.

[0114] also, Figure 8 It is shown Figure 7 A top view of a food waste treatment unit. Figure 9 It is shown Figure 7 A diagram of the dual-axis structure of the blade rotation shaft and the blade rotation shaft in a food waste treatment device.

[0115] Referring to the accompanying drawings, the food waste treatment device according to the sixth embodiment of the present invention includes a drying furnace 100, a crushing blade 810, a stirring blade 910, a drive motor 700, a blade connecting unit 820, and a blade connecting unit 920.

[0116] The drying furnace 100 is a receiving component for feeding and heating kitchen waste.

[0117] Specifically, the drying oven 100 has an internal space of a certain size so as to be able to accommodate a certain amount of food waste.

[0118] Meanwhile, a heater (not shown) is installed inside the drying oven 100, which can simultaneously perform the drying operation while crushing and mixing the kitchen waste.

[0119] The drying oven 100 only needs to be configured to stably heat and process food waste, and its specific structure is of course not limited by the present invention.

[0120] Furthermore, a pressure regulating unit 300 can be connected to the drying oven 100 via a gas flow pipe 200 to regulate the pressure inside the drying oven.

[0121] The pressure regulating unit 300 regulates the pressure inside the drying oven 100 while preventing the gas from escaping to the outside of the device. This pressure regulating unit 300 employs a structure where the size of its internal pressure regulating space is variable with the inflow and outflow of gas, thereby maintaining the pressure of the drying oven within a stable range even without venting odor-producing gases from the drying oven 100 to the outside. As an example, to allow the internal pressure regulating space to be variable, the pressure regulating unit 300 can be formed of a flexible material, or be a foldable structure, or employ a cylinder structure with a built-in piston.

[0122] In addition, the drying oven 100 can be connected to a water tank 500 via a gas circulation pipe 400 to collect moisture contained in the gas. The gas circulation pipe 400 may have a spiral circulation section 410 that is cooled by a cooling unit 600 such as a cooling fan.

[0123] On the other hand, the crushing blade 810 and the stirring blade 910 are arranged inside the drying oven 100.

[0124] The shredder 810 rotates to finely shred the kitchen waste inside the drying oven 100.

[0125] In this way, the shredder 810 shreds the kitchen waste, thereby reducing its volume and improving drying efficiency. Specifically, because the shredder 810 shreds the kitchen waste into smaller particles, the total surface area is increased. Furthermore, heat absorption and transfer are accelerated within the shredded particles, allowing moisture inside the particles to more easily move to the surface. Consequently, the smaller, more uniformly shredded particles result in more uniform drying. Due to these shredding effects, both the drying speed and drying quality are improved.

[0126] The stirring blades 910 rotate to stir the kitchen waste inside the drying oven 100.

[0127] In this way, the stirring blades 910 stir the kitchen waste, thereby uniformly crushing the kitchen waste by the crushing blades 810, which can improve the crushing efficiency.

[0128] In addition, the stirring blades 910 improve drying efficiency by agitating the food waste. Specifically, the stirring blades 910 effectively transfer heat within the food waste. Furthermore, they evenly disperse moisture within the food waste and promote air circulation, thereby accelerating moisture removal. Due to this agitation, both the drying speed and drying quality are improved.

[0129] Furthermore, the drive motor 700 rotates the crushing blade 810 and the stirring blade 910, the blade connecting unit 820 connects the crushing blade 810 and the drive motor 700, and the blade connecting unit 920 connects the stirring blade 910 and the drive motor 700.

[0130] Here, the tool rotation shaft 821 of the tool connecting unit 820 is disposed through the blade rotation shaft 921 of the blade connecting unit 920, so that the tool rotation shaft 821 and the blade rotation shaft 921 can be composed of a dual-shaft structure.

[0131] That is, a hollow portion 921a is formed on the blade rotation shaft 921, and the tool rotation shaft 821 is disposed through the hollow portion 921a. Thus, the tool rotation shaft 821 and the blade rotation shaft 921 have the same rotation center and can rotate independently of each other.

[0132] Furthermore, when the blade rotation shaft 821 and the blade rotation shaft 921 configured as described above rotate in opposite directions, the crushing blade 810 and the stirring blade 910 rotate in opposite directions, thereby improving the crushing capacity of kitchen waste.

[0133] Specifically, as an example, the present invention can be configured such that the tool rotation axis 821 and the blade rotation axis 921 rotate in opposite directions.

[0134] The drive motor 700 rotates the crushing blade 810 and the stirring blade 910. In this invention, one drive motor 700 can be used. That is, in this invention, when one drive motor 700 is running, the crushing blade 810 and the stirring blade 910 can be rotated simultaneously.

[0135] The drive motor 700 can be located on the side of the drying oven 100 and configured in the vertical direction.

[0136] If the drive motor 700 is located below the drying furnace 100, the food waste treatment device of the present invention would be quite long in the vertical direction, thus limiting its spatial arrangement. However, since the drive motor 700 is located to the side of the drying furnace 100 and arranged vertically, the present invention can also be arranged in a space with relatively low height.

[0137] In addition, the tool connecting unit 820 connects the crushing tool 810 and the drive motor 700.

[0138] The tool connecting unit 820 includes a tool rotating shaft 821 connected to the crushing tool 810, and the tool rotating shaft 821 can be connected to the motor shaft 710 of the drive motor 700.

[0139] That is, the tool connecting unit 820 may include a tool rotating shaft 821, the upper part of which is connected to the crushing tool 810, and the lower part of which can be connected to the motor shaft 710 of the drive motor 700.

[0140] Furthermore, the tool connecting unit 820 may also include a drive belt 822 connecting the tool rotation shaft 821 and the motor shaft 710. As an example, a motor shaft pulley 710a is formed on the motor shaft 710, and a rotation shaft pulley 821a is formed on the tool rotation shaft 821. The motor shaft pulley 710a and the rotation shaft pulley 821a are connected by the drive belt 822, so that when the motor shaft 710 rotates, the tool rotation shaft 821 can be rotated by the drive belt 822.

[0141] As a result, when the drive motor 700 is running, the rotation of the motor shaft 710 rotates the blade rotating shaft 821, ultimately causing the crushing blade 810 to rotate.

[0142] Meanwhile, the blade connecting unit 920 connects the stirring blade 910 and the drive motor 700.

[0143] The blade connecting unit 920 includes a blade rotation shaft 921 connected to the stirring blade 910, and a driven gear 922 may be formed on the blade rotation shaft 921. The driven gear 922 can mesh with the drive gear 720 formed on the motor shaft 710.

[0144] That is, the blade connecting unit 920 may include a blade rotating shaft 921, the upper part of which is connected to the stirring blade 910, and the lower part of which may be formed with a driven gear 922. The driven gear 922 meshes with the drive gear 720 formed on the motor shaft 710, so that it rotates in conjunction with the drive gear 720 when the drive gear 720 rotates.

[0145] As a result, when the drive motor 700 is running, the rotation of the motor shaft 710 rotates the drive gear 720 and the driven gear 922, thereby rotating the blade rotation shaft 921, and finally causing the stirring blade 910 to rotate.

[0146] The cutter connecting unit 820 and the blade connecting unit 920 configured as described above enable the crushing cutter 810 and the stirring blade 910 to rotate simultaneously in opposite directions when a drive motor 700 is running.

[0147] As an example, when the drive motor 700 is running, the crushing blade 810 can rotate at high speed, while the stirring blade 910 can rotate at low speed. Thus, in order to make the stirring blade 910 rotate at a relatively lower speed than the crushing blade 810, the driven gear 922 of the blade connecting unit 920 can be formed to be larger than the drive gear 720 of the motor shaft 710.

[0148] On the other hand, the crushing blade 810 may include a plurality of brackets 811 and a plurality of cutting components 812.

[0149] Multiple brackets 811 can be installed on the tool rotation axis 821 at intervals in the vertical direction.

[0150] Furthermore, multiple cutting components 812 can be installed at intervals along the respective edges of multiple brackets 811.

[0151] Thus, multiple cutting components 812 are arranged circumferentially along the blade rotation axis 821 and multiple are arranged vertically, thereby effectively crushing kitchen waste contained to a certain height in the drying oven 100.

[0152] Specifically, the cutting component 812 and the stirring blade 910 can each adopt a structure that bends along the direction of rotation.

[0153] The cutting member 812 can be a structure that is bent along the rotation direction, that is, a structure in which one side of the cutting member 812 located in the rotation direction is recessed inward.

[0154] Therefore, when the cutting component 812 rotates, it can crush the kitchen waste by piercing into and tearing it in the direction of rotation.

[0155] Furthermore, the stirring blade 910 can adopt a structure that is bent along the direction of rotation, that is, a structure in which the side of the stirring blade 910 located in the direction of rotation is recessed inward.

[0156] Therefore, when the stirring blade 910 rotates, the kitchen waste located in the direction of rotation of the stirring blade 910 can be stirred.

[0157] More specifically, as described above, the cutter rotation shaft 821 and the blade rotation shaft 921 are configured to rotate in opposite directions to each other, and the cutting member 812 and the stirring blade 910 may adopt a structure that bends in opposite directions to each other.

[0158] That is, the cutting component 812 and the stirring blade 910 each adopt a structure that bends along the direction of rotation. As the cutting tool rotation axis 821 and the blade rotation axis 921 rotate in opposite directions, the cutting component 812 and the stirring blade 910 adopt a structure that bends in opposite directions.

[0159] As a result, the food waste treatment device according to the present invention adopts a dual-axis structure of a blade rotation shaft 821 and a blade rotation shaft 921, which causes the crushing blade 810 and the stirring blade 910 to rotate in opposite directions to each other, thereby enabling the cutting member 812 to rotate in the opposite direction to the rotation of the stirring blade 910 to improve the crushing capacity of food waste.

[0160] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art should understand that the present invention can be implemented in other specific forms without changing the technical concept or basic characteristics of the invention. Therefore, it should be understood that the embodiments described above are merely illustrative in all respects and not restrictive.
