Description

Technical Field

[0002] Current food braising methods rely heavily on manual labor, with low levels of automation, requiring a large number of workers to perform high-intensity tasks. Furthermore, the limited manual operation results in low production efficiency. Additionally, after braising in the pot, the food needs to be tilted and poured out, leading to a high rate of food breakage.

[0003] Meanwhile, the existing braised food production line still has the following problems: the temperature of the food that has just been braised is high and the cooling time is long, which is not conducive to speeding up the production efficiency of the braised food production line; manually splitting and stacking the material baskets is labor-intensive and inefficient; manually flipping the material baskets is labor-intensive and inefficient; the water in the main body of the traditional washing machine is often discharged after only one use, resulting in a large amount of water consumption, which leads to water waste and high water costs.

[0015] This invention has the following advantages: A hoisting and conveying device vertically lifts and transports multi-layered food baskets into and out of the braising pot, eliminating the need to tilt the pot and reducing food breakage. The pot braises one stack of food baskets at a time, ensuring even cooking of more food while maintaining spacing between items, allowing for uniform flavor absorption and cooking. Furthermore, the stacked food baskets save space during cooling after braising. The addition of heating and cooling boxes on the outside of the pot prevents the cooked food from leaving the pot. Internal cooling lowers the temperature of the food after cooking and enhances its flavor. The lower cooking temperature also shortens the external cooling time, increasing production line efficiency, accelerating food turnover, and reducing the required cooling area. The vertical arrangement of the cooling and heating chambers, through convection of the broth, ensures a more even temperature distribution within the pot, resulting in consistent braised food. The stacking and unpacking machine separates and stacks the food crates, achieving high efficiency and reducing worker fatigue. The two-stage motion using the first and second cylinders minimizes the vertical space occupied by the drive unit. This design lowers the conveyor line height, making it easier for workers to operate; the various crate unpacking and crate flipping machines are interchangeable, reducing maintenance costs; two sets of grooved plates support both sides of the crate, and by rotating these plates, the crate is flipped 180 degrees so that the opening faces the same direction. During cleaning, wastewater and food residue flow out of the crate under gravity, preventing residue from remaining inside and improving cleanliness; each set of grooved plates consists of an even number of evenly distributed grooves, ensuring that both grooves in the same set are simultaneously horizontal, allowing for efficient material handling. The entry and exit of the material frames can be carried out simultaneously, saving time and improving the efficiency of flipping the material frames. Water is recycled three times through three water tanks. As the material frames move, the cleanliness of the cleaning water gradually improves. This means that even when using recycled water to clean the material frames, the cleanliness of the material frames after each rinse with increasingly cleaner water is the same as if clean water were used throughout the process. This significantly saves water consumption and reduces water costs compared to using clean water throughout the process. A blower at the end of the frame blows a high-speed airflow to remove residual water from the material frames, accelerating the subsequent drying process and reducing microbial growth.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example 1: like Figures 1 to 20 As shown, this embodiment provides a poultry braising production line, including: a first stacking machine 2, a hoisting conveying device 3, and a braising pot 4. The first stacking machine 2 and the braising pot 4 are respectively located below the hoisting conveying device 3. The first stacking machine 2 is used to vertically stack multiple baskets 10. The hoisting conveying device 3 is used to transport the baskets 10 between the first stacking machine 2 and the braising pot 4. A first opening is formed above the braising pot 4. During operation, the baskets 10 loaded with food enter the first stacking machine 2, which stacks multiple baskets 10 one by one into a vertical stack. The hoisting conveying device 3 lifts the stacked baskets 10 and transports them above the braising pot 4, and then places the stack of baskets 10 into the braising pot 4 through the first opening. The braising pot 4 performs braising operations on the food in the baskets 10. After braising is completed, the hoisting conveying device 3 simultaneously lifts the braising stack of baskets 10 away from the braising pot 4.

[0021] Preferably, the system also includes a feeding machine 1, a cooling and temporary storage conveyor belt 5, a washing machine 7, a full-frame temporary storage conveyor belt 9, a feeding conveyor 12, a shoveling conveyor belt 13, a second destacking and stacking machine 51, and an unloading conveyor belt 52. The feeding machine 1 is connected to the feeding conveyor 12. The end of the feeding conveyor 12 is connected to the beginning of the shoveling conveyor belt 13. The end of the shoveling conveyor belt 13 is connected to the beginning of the first destacking and stacking machine 2. The end of the first destacking and stacking machine 2 is connected to the full-frame temporary storage conveyor belt 9. The full-frame temporary storage conveyor belt 9 and the cooling and temporary storage conveyor belt 5 are located below the hoisting and conveying device 3. The end of the cooling and temporary storage conveyor belt 5 is connected to the beginning of the second destacking and stacking machine 51. The end of the second destacking and stacking machine 51 is connected to the beginning of the unloading conveyor belt 52. The end of the unloading conveyor belt 52 is connected to the beginning of the washing machine 7. The end of the washing machine 7 is connected to the shoveling conveyor belt 13. During operation, food enters the feeding conveyor 12 from the feeding machine 1 and is then transported by the feeding conveyor 12 to the food frames 10 placed on the arranging conveyor belt 13. The arranging is done manually or mechanically to ensure the food is evenly distributed in the food frames 10, preventing food from piling up in one place and causing incomplete braising. After arranging on the arranging conveyor belt 13, the food-filled food frames 10 are conveyed to the first stacking machine 2. After being stacked on the first stacking machine 2 and braised in the braising pot 4, the hoisting conveyor 3 suspends a stack of food frames 10 above the cooling temporary storage conveyor belt 5. The food in the food frames 10 is cooled above the cooling temporary storage conveyor belt 5 and, during the cooling process, is transported by the cooling temporary storage conveyor belt 5 to the second stacking machine 51. The second stacking machine 51 separates the stack of food frames 10 into individual single-layer food frames 10, which then sequentially enter the unloading conveyor belt 52. Food is removed from the loading frames 10 on the unloading conveyor belt 52 by manual labor or machinery and sent to the packaging production line. Empty frames 10 enter the cleaning machine 7 for cleaning to remove dirt. After cleaning, the frames 10 are conveyed to the unloading conveyor belt 13 for unloading again, thus completing the cycle of loading and cleaning of the frames 10.

[0022] Preferably, the system further includes a material distribution conveyor 11, a guide baffle 14, and a baffle cylinder 15. The feeding machine 1 is connected to the first end of the material distribution conveyor 11, the end of the material distribution conveyor 11 is connected to the first slide rail 16, the side of the material distribution conveyor 11 is connected to the feeding conveyor 12, the guide baffle 14 is located above the material distribution conveyor 11 and is rotatably connected to the frame of the material distribution conveyor 11, and the two ends of the baffle cylinder 15 are rotatably connected to the frame of the material distribution conveyor 11 and the guide baffle 14, respectively. During operation, food first enters the material distribution conveyor 11 from the feeding machine 1, and then enters the feeding conveyor 12 after passing through the material distribution conveyor 11. In mass production of braised food, the guide baffle 14 rotates to a position above the belt of the material distribution conveyor 11, such as... Figure 2As shown, the food on the conveyor belt is guided to the slide, and the food slides onto the conveyor belt of the side feeding conveyor 12. When small-batch production of braised food is required, such as when testing new products, the guide baffle 14 rotates away from the belt of the distributing conveyor 11. The food on the conveyor belt of the distributing conveyor 11 moves to the end of the distributing conveyor 11 and falls into the first slide 16, and slides along the first slide 16 into the material frame 10 placed below it. Afterwards, the material frame 10 filled with food is manually placed into the braising pot for trial production.

[0023] Preferably, the system also includes an empty frame temporary storage conveyor belt 8, a third frame dismantling machine 81, and a fourth frame dismantling machine 82. The end of the third frame dismantling machine 81 is connected to the beginning of the empty frame temporary storage conveyor belt 8, and the end of the empty frame temporary storage conveyor belt 8 is connected to the beginning of the fourth frame dismantling machine 82. The end of the fourth frame dismantling machine 82 is connected to the side of the material placement conveyor belt 13. After leaving the washing machine 7, the material frames 10 enter the third frame dismantling machine 81, which stacks the individual material frames 10 one by one to reduce the space occupied by the empty material frames 10. The stacked material frames 10 are conveyed to the empty frame temporary storage conveyor belt 8, where the empty material frames 10 are temporarily stored. When it is necessary to produce braised food, the stack of material frames 10 is conveyed by the end of the empty frame temporary storage conveyor belt 8 to the fourth frame dismantling machine 82, where the stack of material frames 10 is dismantled into individual material frames 10 one by one. The disassembled material frames 10 are fed one by one into the material conveyor belt 13.

[0024] Preferably, the system further includes a second slide rail 121, whose upper and lower ends are respectively connected to the feeding conveyor 12 and the shoveling conveyor belt 13. The fourth stacking machine 82 directly transports the material frames 10 to the beginning of the shoveling conveyor belt 13, that is, the material frames 10 are located below the second slide rail 121, and the shoveling conveyor belt 13 does not move at this time. After the shoveling conveyor belt 13 is loaded, it drives the material frames 10 to move towards the end, while the feeding conveyor 12 stops moving intermittently. After the food-filled material frames 10 move to the end of the shoveling conveyor belt 13, new empty material frames 10 are output to the beginning of the shoveling conveyor belt 13, and the feeding conveyor 12 starts moving to continue loading material into the material frames 10. More preferably, the shoveling conveyor belt 13 is a roller conveyor, with a long roller 132 at the beginning and a short roller at the end. After the material frame 10 moves onto the short roller, the short roller stops moving, and the lifting frame 133 is driven upward by the cylinder, which in turn drives the steering conveyor 134 mounted above it to move upward. The belts on both sides of the steering conveyor 134 contact the bottom of the material frame 10, lifting the material frame 10 so that it is separated from the contact with the short roller. Then, the belt movement of the steering conveyor 134 transports the material frame 10 above the first destacking machine 2. After the material frame 10 leaves the steering conveyor 134, the cylinder drives the lifting frame 133 to return to its original position downward, so that the steering conveyor 134 is lower than the short roller. The conveying direction of the steering conveyor 134 is perpendicular to the sway conveyor belt 13.

[0025] Preferably, the system also includes a frame-flipping machine 6. The first and second ends of the cleaning machine 7 are connected to the frame-flipping machine 6. The frame-flipping machine 6 is used to flip the material frame 10 180 degrees. The frame-flipping machine 6 at the first end of the cleaning machine 7 is connected to the unloading conveyor belt 52, and the frame-flipping machine 6 at the second end of the cleaning machine 7 is connected to the first end of the third frame-disassembly machine 81. The frame-flipping machine 6 at the first end flips the material frame 10 so that the opening faces downward, making it easier for the cleaning machine 7 to clean it. The frame-flipping machine 6 at the second end flips the frame 10 so that the opening faces upward, restoring the material frame 10 to its ready-to-load state.

[0026] It should be noted that the "first end" refers to the entry end of the food or the material frame 10, and the "last end" refers to the exit end of the food or the material frame 10. Each side of the square frame 10 has a through hole 102, which facilitates the broth to enter the material frame 10 during braising and also allows the water from the washing machine 7 to pass through the through hole 102 for rinsing.

[0027] Preferably, the hoisting and conveying device 3 includes a first guide rail 31, a first moving frame 32, a second guide rail 33, a first traveling motor 34, a second traveling motor 35, a second moving frame 36, a lifting motor 37, a drum 38, and a lifting device 39.

The second traveling wheel is rotatably connected to the second moving frame 36. The second traveling wheel is connected to the second guide rail 33. The second moving frame 36 is fixedly connected to the lifting motor 37. The drum 38 is rotatably connected to the second moving frame 36. The drum 38 is fixedly connected to the wire rope. The wire rope is connected to the lifting device 39.

[0028] Example 2: This embodiment is a further improvement on Embodiment 1. The braising pot 4 includes a pot body 41, a heating chamber 42, and a cooling chamber 43. A first opening is formed at the top of the pot body 41. The outer side of the pot body 41 is in contact with and fixedly connected to the heating chamber 42 and the cooling chamber 43, respectively. The height of the cooling chamber 43 is higher than the height of the heating chamber 42. When braising food in the broth in the pot body 41, steam passes through the heating chamber 42, heating both the heating chamber 42 and the pot body 41. Due to the rising heat of the fluid, the hotter broth at the bottom will convection upwards, thereby heating the broth in the pot body 1 evenly and braising the food in different areas more evenly. After the food is braised, the steam supply to the heating chamber 42 is stopped, and cold water is introduced into the cooling chamber 43 to cool the broth in the pot body 41. During this process, the cold fluid sinks, and the cooler broth at the top convections downwards, thereby cooling the broth in the pot body 41 evenly and cooling the food in different areas more evenly. Cooling the food after braising not only lowers its temperature but also allows it to absorb more flavor and improves its texture.

[0029] Preferably, multiple braising pots 4 are arranged below the hoisting and conveying device 3 so that multiple braising operations can be carried out simultaneously, thereby improving the utilization rate of the hoisting and conveying device 3 and increasing the output of braised food.

[0030] Preferably, the heating box 42 includes a first heating box 421 and a second heating box 422. The first heating box 421 is in contact with and fixedly connected to the bottom surface of the pot body 41. The cooling box 43 and the second heating box 422 are respectively fixedly connected to the side surface between the first opening and the bottom surface of the pot body 41. The cooling box 43 is located above the second heating box 422. The first heating box 421 and the second heating box 422 heat simultaneously from both the bottom and side surfaces, avoiding the problem of uneven heating of the soup.

[0031] Preferably, the system further includes a heating inlet pipe 423 and a heating outlet pipe 424. The heating box 42 is fixedly connected to and communicates with the heating inlet pipe 423 and the heating outlet pipe 424, respectively. Steam enters the first heating box 421 and the second heating box 422 through the heating inlet pipe 423 and then leaves through the heating outlet pipe 424. The system also includes a cooling inlet pipe 431 and a cooling outlet pipe 432. The cooling box 43 is fixedly connected to and communicates with the cooling inlet pipe 431 and the cooling outlet pipe 432, respectively. Cooling water enters the cooling box 43 through the cooling inlet pipe 431 and then leaves through the cooling outlet pipe 432.

[0032] Preferably, the heating inlet pipe 23 and the heating outlet pipe 24 are respectively connected to the water distribution manifold, which is connected to the first heating box 21 and the second heating box 22; the cooling inlet pipe 31 and the cooling outlet pipe 32 are respectively connected to the water distribution manifold, which is connected to multiple cooling boxes 3.

[0033] Preferably, the heating inlet pipe 23 is equipped with a proportional valve 25 to regulate the amount of steam entering; the heating outlet pipe 24 is equipped with a steam trap 26.

[0034] Preferably, such as Figure 11 As shown, it also includes a cover plate 411, which is located on the outside of the pot body 41 and fixedly connected to the pot body 41. The heating box 42 and the cooling box 43 are respectively located on the outside of the pot body 41 and between the cover plate 411. The cover plate 411 prevents workers from touching the heating box 42, thus avoiding burns caused by accidental contact. At the same time, the cover plate 411 also serves to insulate the heating box 42 and the cooling box 43.

[0035] Preferably, the pot body 41 is a rectangular pot body, and each side of the pot body 41 is fixedly connected to the cooling box 43, so that the multi-sided cooling is more uniform.

[0036] Preferably, the pot body 41 further includes a first limiting plate 413 and a second limiting plate 414. The inner walls of the two sides corresponding to each corner of the pot body 41 are fixedly connected to the vertical first limiting plate 413, and the lower interior of the pot body 41 is fixedly connected to the horizontal second limiting plate 414. The first limiting plate 413 and the second limiting plate 414 are used to limit the position of the material frame, so that there is a gap between the material frame 10 and the inner wall of the pot body 41.

[0037] Preferably, the pot also includes a broth extraction pipe 44 and an oil overflow pipe 45, which are fixedly connected to the pot body 41 and communicate with the interior of the pot body 41. The height of the oil overflow pipe 45 is higher than that of the broth extraction pipe 44. When braising meat, the fat in the meat dissolves into the broth, creating an oil layer on top, which is detrimental to the braising of the food on top. Therefore, when there is too much oil on the surface, the valve on the oil overflow pipe 45 is opened, and the oil is discharged into the pot body 41 through the oil overflow pipe 45. After the day's work is finished braising the food, the broth in the pot body 41 is discharged through the broth extraction pipe 44 and stored in a cold storage.

[0038] Preferably, the system also includes temperature sensors 46, with the pot body 41 fixedly connected to multiple temperature sensors 46, and the multiple temperature sensors 46 having a height difference between them.

The two ends of the first connecting rod 210 are respectively rotatably connected to the end of the first radial plate 232 away from the first rotating shaft 231 and the end of the second radial plate 242 away from the second rotating shaft 241. The first connecting rod 210 is used to make the two shafts rotate synchronously, thereby causing the first connecting rods 255 on the front and rear sides to push the lifting frame 25 simultaneously, improving the stability of the lifting frame 25 when it is raised or lowered.

[0044] Preferably, both ends of the slide rod 26 pass through the lifting frame 25, and the third cylinder 251 is connected to the lifting frame 25. The third cylinder 251 drives the two slide rods 26 corresponding to the lifting frame 5 connected to it to move synchronously.

The first guide post 212 is fixedly connected to the front and rear sides above the base 211, and the first guide post 212 passes through the lifting frame 25 and is slidably connected to the lifting frame 25.

[0047] Preferably, the first conveyor 27 is a chain conveyor, and the frame of the first conveyor 27 is fixedly connected to the first frame 21. Two chains 271 are arranged on the left and right sides above the conveyor 27. The height of the chains 271 is lower than that of the slide bar 26 because the fixing hole 290 of the material frame 29 supported above the chains 271 is higher than the chains 271.

[0048] Preferably, the system further includes a front positioning block 281 and a rear positioning block 282, located on the front and rear sides between two chains 271. The front positioning block 281 is connected to a first driving device (not shown in the figure), which drives at least a portion of the front positioning block 281 to move on the upper and lower sides of the upper chain 271. The rear positioning block 282 rotates relative to the first frame 21, with its rotation axis being a left-right axis. The rear positioning block 282 is connected to a second driving device (not shown in the figure), which drives the rear positioning block 282 to rotate, and a portion of the rear positioning block 282 moves on the upper and lower sides of the upper chain 271. When the rear positioning block 282 rotates upward, its upper end moves from back to front, thereby driving the material frame 10, which is not in contact with the front positioning block 281, to move forward to a designated position. More preferably, the first and second driving devices can be cylinders or motors. More preferably, the two rear positioning blocks 282 on the left and right sides are fixedly connected to the fixing rod 283 respectively, the second driving device is connected to and drives the fixing rod 283, and the fixing rod 283 is rotatably connected to the frame of the first frame 21 or the frame of the first conveyor 27.

[0049] Preferably, it also includes limiting slide bars 213, with two limiting slide bars 213 located on the left and right sides above the first conveyor 27, respectively, and the limiting slide bars 213 are fixedly connected to the first frame 21.

[0050] When stacking the material frame 10: The material frame 10 enters the first conveyor 27 between the two limiting slide bars 213. The upper parts of the left and right chains 271 on the first conveyor 27 (i.e., the straight parts above the chains 271) contact the bottom surface of the material frame 10, and the chains 271 drive the material frame 10 to move from back to front. The first driving device drives the front positioning block 281 to move linearly or rotate, so that all or part of the front positioning block 281 is higher than the upper part of the chains 271. The front side of the material frame 10 is blocked and positioned by the front positioning block 281. Then, the second driving device drives the rear positioning block 282 to rotate, so that part of the height of the rear positioning block 282 is higher than the upper part of the chains 271, until the rear positioning block 282 contacts the rear side of the material frame 10. In this way, the material frame 10 is positioned by the front positioning block 281, the rear positioning block 282, and the left and right limiting slide bars 213. At this point, the two fixing holes 100 on each side of the material frame 10 are coaxial with the corresponding slide rods 26. The third cylinder 251 drives the slide rods 26 to move closer to the material frame 10 until the slide rods 26 are inserted into the fixing holes 100. After that, the rear positioning block 282 resets, so that its highest height is lower than the upper part of the chain 271 to avoid blocking the entry of new material frames 10. Then, the second cylinder 222 extends to its maximum stroke, and the second rotating shaft 241 is driven by the first connecting rod 210 to rotate synchronously with the first rotating shaft 231, thereby driving the four first connecting rods 255 to rotate synchronously, raising the lifting frame 25 and the material frame 10 to the first height. After that, the first cylinder 221 extends to its maximum stroke, driving the lifting frame 25 and the material frame 10 to continue moving upward to a second height, the size of which is equal to the distance between the fixing holes 100 of two adjacent material frames 10 when stacked. After the material frame 10 is raised to the first height, the first conveyor 27 drives the new material frame 10 to move below the previous material frame 10 until the new material frame 10 contacts the front positioning block 281. Then, the rear positioning block 282 moves upward, positioning the new material frame 10 and fixing its position relative to the first frame 21. After the new material frame 10 is positioned, the second cylinder 222 retracts to its minimum stroke, driving the limiting protrusion 101 on the top of the new material frame 10 to insert into the corresponding limiting groove 102 on the bottom surface of the previous material frame 10, thereby restricting the horizontal movement between the two adjacent material frames 10. After the upper and lower material frames 10 contact each other, the third cylinder 251 drives the slide rod 26 to move away from the material frame 10 until the slide rod 26 leaves the fixing hole 100 of the previous material frame 10. The second cylinder 222 retracts to its minimum stroke, driving the lifting frame 25 and the slide rod 26 to move downward, making the slide rod 26 coaxial with the fixing hole 100 of the new material frame 10. Then, the third cylinder 251 drives the slide bar 26 to insert into the fixing hole 100 of the new material frame 10, and the second cylinder 222 and the first cylinder 221 drive the stacked previous material frame 10 and the new material frame 10 to move upward synchronously. This cycle is repeated until a specified number of material frames 10 are stacked.After the last material frame 10 is stacked, the slide bar 26 leaves the fixing hole 100 of the material frame 10. Then the front positioning block 281 moves downward to stop blocking the stacked material frames 10. The stacked material frames 10 are driven forward by the first conveyor 27 to leave the stacking machine.

[0051] When splitting a stack of material frames 10: The stack of material frames 10 is placed at a designated position on the first conveyor 27, or driven to a designated position by the first conveyor 27. After the first conveyor 27 contacts the front positioning block 281, the positioning block 282 rises to position the bottommost material frame 10. After positioning, the first cylinder 221 extends to its maximum stroke, driving the lifting frame 25 to move upward to a second height, making the slide rod 26 coaxial with the fixing hole 100 of the second layer of material frames 10 from bottom to top. The third cylinder 251 drives the four slide rods 26 on both sides to insert into the fixing hole 100 to fix the second layer of material frames 10. The second cylinder 222 extends to its maximum stroke, the front positioning block 281 moves downward, stopping the obstruction of the bottommost material frame 10, and the bottommost material frame 10 is driven away from under the stack of material frames 10 by the first conveyor 27. Then, the front positioning block 281 moves upward, and the first cylinder 221 and the second cylinder 222 retract to their minimum stroke, placing the original second-layer material frame 10 above the chain 271. The third cylinder 251 drives the four sliding rods 26 on both sides to be pulled out of the fixing holes 100. This cycle repeats until the uppermost material frame 10 contacts the chain 271, at which point the sliding rods 26 are pulled out of the fixing holes 100, and the front positioning block 281 moves downward to stop blocking the material frame 10.

[0052] Example 4: This embodiment is a further improvement based on any one of the embodiments one to three. The frame flipping machine 6 includes a second frame 61, a grooved plate 62, a connecting column 63, and a first motor 64. The two ends of the connecting column 63 are respectively fixed to two sets of grooved plates 62. Each set of grooved plates 62 includes at least one grooved plate 62. The grooved plate 62 forms a groove 620. The grooved plates 62 of the two sets of grooved plates 62 correspond one-to-one. The grooves 620 of the corresponding two grooved plates 62 are provided with a third opening 6200 facing each other. The groove 620 forms a second opening 6201 at the end away from the connecting column 63. The first motor 64 drives the connecting column 63 to rotate relative to the second frame 61.

[0053] Preferably, each group of grooved plates 62 includes an even number of grooved plates 62, and the grooved plates 62 in each group are evenly arranged circumferentially. An even number of grooved plates 62 ensures that when one grooved plate 62 is flipped and positioned horizontally, another grooved plate 62 is also horizontal, so that when one material frame 10 leaves the grooved plate 2, another material frame 10 simultaneously enters another grooved plate 62, such as... Figures 5 to 7 As shown, the material frame 10 enters and leaves simultaneously, saving working time.

[0054] Preferably, the groove plate 62 includes a side plate 621 and a bottom plate 622. The bottom plate 622 is rectangular and its three sides are fixedly connected to the side plate 621. The side plate 621 and the bottom plate 622 form a groove 620. The side plate 621 is used to support and limit the material frame 10, preventing the side plate 621 from falling out of the groove 620 during the flipping process.

[0055] Preferably, the side plate 621 has a guide plate 623 formed at the second opening 6201, and the guide plate 623 is inclined outward. The multiple guide plates 623 are flared at the end of the groove plate 62 away from the connecting post 63, which serves to guide the material frame 10 into the groove 20.

[0056] Preferably, the system further includes a second conveyor 66, located below the connecting column 63. The conveying direction of the second conveyor 66 is perpendicular to the rotation axis of the connecting column 63, and both the conveying direction of the second conveyor 66 and the rotation axis of the connecting column 63 are parallel to the horizontal plane. Figure 14 As shown, the conveying direction of the second conveyor 66 is the front-to-back direction, and the rotation axis of the connecting column 63 is the axis in the left-to-right direction.

[0057] Preferably, the second conveyor 66 is a chain conveyor, and the frame of the second conveyor 66 is fixedly connected to the second frame 61. The chain conveyor... Figure 3 The second chains 661 on the left and right sides of the center contact the bottom of the material frame 10, and the distance between the two second chains 661 is less than the distance between the two sets of groove plates 62. There is no connecting structure in the middle of the two second chains 661 to avoid blocking food residue in the material frame 10 from falling.

[0058] Preferably, the assembly also includes a mounting plate 67 and a rotating shaft 69. The two ends of the connecting column 63 are fixedly connected to the mounting plate 67, and the side of the mounting plate 67 away from the connecting column 63 is fixedly connected to the rotating shaft 69. The rotating shaft 69 is coaxial with the connecting column 63 and is rotatably connected to the second frame 61.

[0059] Preferably, the system further includes a mounting bracket 68, which corresponds one-to-one with the grooved plate 62. The mounting bracket 68 is fixedly connected to the mounting plate 67 and the grooved plate 62, and the mounting bracket 68 and the grooved plate 62 are fixed at multiple points in the radial direction. Since the grooved plate 62 is made of a relatively thin sheet material, the multiple fixing points of the mounting bracket 68 to the grooved plate 62 can strengthen the grooved plate 62 and reduce its deformation.

[0060] Preferably, the system also includes a diagonal brace 681, which is located between two adjacent mounting brackets 68. Both ends of the diagonal brace 681 are fixedly connected to the two adjacent mounting brackets 68 to improve strength.

[0061] Preferably, the system further includes an indexer 65. The first motor 64 and the indexer 65 are fixedly connected to the second frame 61. The output shaft of the first motor 64 is connected to the input shaft of the indexer 65. The output shaft of the indexer 65 is connected to a rotating shaft 69 and drives the rotating shaft 69 to rotate, so that the rotating shaft 69 rotates by a fixed angle each time it rotates. This angle is the included angle between two adjacent groove plates 2 in the same group. More preferably, the indexer 65 is a cam divider.

[0062] Working principle: such as Figure 14 As shown, the second conveyor 66 carries the bottom of the material frame 10 and drives the material frame 10 to move linearly from front to back. The material frame 10 enters the groove 620 of the grooved plate 62, which is located on the front side, through the second opening 6201. Then, the indexer 65 rotates, and its rotation angle is the same as the included angle between two adjacent grooved plates 62 in the same group. When the grooved plate 62 carrying the material frame 10 rotates to the rear side and is parallel to the horizontal plane, the material frame 10 is flipped 180 degrees so that the opening faces downward. The tops of the front and rear side plates of the material frame 10 contact the second chain 6661, and the material frame 10 leaves the groove 620 through the second opening 6201 under the drive of the second chain 6661. After leaving the groove 620, the material frame 10 is conveyed to the washing device by the second conveyor 66. The downward-facing opening of the material frame 10 facilitates the falling of food residues away from the material frame 10 during washing.

[0063] It should be noted that the second conveyor 66 can set a fixed spacing between the material frames 10 and maintain a fixed conveying speed to ensure that the material frames 10 can enter the groove 620 in time when the groove plate 62 on the front side is horizontal, and that the material frames 10 will not enter the position between the groove plates 62; the second conveyor 66 can also start and stop continuously. When the groove plate 62 is horizontal, it starts to ensure that the material frames 10 enter and leave the groove 620, and when the groove plate 62 rotates, the second conveyor 66 stops to prevent the material frames 10 from entering the position between the groove plates 62.

[0069] Preferably, the main wash water pipe 74 includes a vertical water pipe 741 and a horizontal water pipe 742. The vertical water pipe 741 is annular, and the horizontal water pipe 742 is U-shaped.

[0076] Working Principle: During operation, the material frame 10, which has been flipped so that its opening faces downwards, contacts the chain on the upper side of the third chain conveyor 72. The material frame 10 is driven by the chain to move in a straight line from front to back. The material frame 10 first passes through the pre-wash water pipe 73, where the pre-wash nozzles 730 spray water onto the material frame 10 from four directions (up, down, left, and right) to initially wash away floating dust and surface dirt and soften the surface dirt. The wastewater after washing flows out from the drain hole (not shown in the figure) of the table 711 and is transported along the pipe to the sewage treatment equipment or sewer. Afterwards, the material frame 10 passes through the vertical water pipe 741, where the main wash nozzles 743 spray water onto the material frame 10 from four directions (up, down, left, and right). The water pressure of the main wash nozzles 743 is higher than that of the pre-wash nozzles 730. The high-speed water flow impacts the material frame 10, washing away stubborn dirt. The water sprayed by the main wash nozzles 743 may contain detergent to improve the removal effect on oil stains. Afterwards, the material frame 10 passes through the rinsing water pipe 75, where rinsing nozzles 751 spray water onto the material frame 10 from four directions (up, down, left, and right) to wash away any remaining surface dirt. The water from the rinsing water pipe 75 does not contain detergent, thus reducing detergent residue on the surface of the material frame 10. Next, the material frame 10 passes through the flushing water pipe 76, where flushing nozzles 760 spray water onto the material frame 10 from four directions (up, down, left, and right) to further remove dirt and residue from the surface of the material frame 10. Finally, the material frame 10 passes through the second outer casing 715, where water droplets on the surface of the material frame 10 are driven away by the airflow from the blower 710. After cleaning, the material frame 10 is driven backwards by the third chain conveyor 72 and leaves the cleaning machine. The water from the flushing water pipe 76 is not recycled water and can come from the municipal water supply network. The water rinsed by the flushing water pipe 76 enters the rinsing water tank 79 through a pipe (not shown in the figure) for primary recycling. Rinse water pipe 75 sprays out the primary recycled water for cleaning. The water sprayed from rinsing water pipe 75 enters the main wash water tank 78 through a pipe for secondary recycling. Detergent is added to the secondary recycled water in the main wash water tank 78 periodically, either mechanically or manually. Main wash water pipe 74 sprays out secondary recycled water mixed with detergent for cleaning. The sprayed water enters the pre-wash water tank 77 through a pipe for tertiary recycling. Finally, the tertiary recycled water is sprayed out by pre-wash water pipe 73 for pre-washing. The sprayed water is not recycled and is discharged directly as wastewater.

Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
