Description

Technical Field

[0001] This invention relates to the field of brine filtration technology, specifically to a brine circulation filtration device for braised chicken processing. Background Technology

[0002] While frying the chicken before braising can lock in its aroma and enhance its color, the chicken skin scraps, meat bits that fall off during frying, and the blood foam produced during subsequent braising are very likely to form suspended matter and sediment in the high-temperature braising liquid. This not only affects the appearance of the finished product but also accelerates the rancidity of the braising liquid. Traditional filtration often employs a step-by-step "scouring then filtering" method, which involves first using a strainer to remove large pieces of residue, and then using a fixed filter screen or gauze for secondary filtration. This method is inefficient, as fine particles easily clog the filter screen pores, causing a sharp drop in flow rate. Furthermore, the filter screen requires frequent cleaning, making it difficult to support large-scale continuous operations. More importantly, brine tanks typically have a capacity of several hundred liters, and the brine needs to be filtered while hot at temperatures above 80°C to prevent grease from solidifying and encapsulating impurities. However, this also introduces significant risks associated with manual operation. In addition, existing filter structures are generally simple, mostly static flat or cylindrical designs. During filtration, debris easily accumulates on the surface to form a "filter cake," which not only reduces the flow rate but may also cause brine splashing due to uneven pressure, threatening operational safety.

[0003] Based on this, the present invention designs a brine circulation filtration device for braised chicken processing to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a brine circulation and filtration device for processing braised chicken, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a brine circulation and filtration device for processing braised chicken, comprising a base frame, a transmission frame fixedly connected to the top of the base frame, a rotating plate rotatably connected to the inner side of the transmission frame, and further comprising: The rotating filter assembly includes several filter frames that are vertically and equidistantly distributed inside the brine tank. The filter frames are fixedly connected to a connecting frame. A flipping mechanism is provided at the top of the connecting frame. The flipping mechanism is used to drive the connecting frame to rotate horizontally and move vertically.

[0006] As a further embodiment of the present invention, the flipping mechanism includes a lead screw, which is fixed to the top of the connecting frame. A sleeve is screwed onto the top of the lead screw, and a fixing rod is fixedly connected to the top of the fixing frame. The sleeve is fixed to the fixing rod.

[0007] As a further embodiment of the present invention, a first fixed frame is fixedly connected to the top of the base frame, and a second fixed frame is fixedly connected to one side of the top of the base frame. A first transmission gear is provided at the top of both the first and second fixed frames. The two first transmission gears are rotatably connected to a second transmission belt. The rotation center of the top of the rotating plate is rotatably connected to the top of the first fixed frame and the first transmission belt. A rack that meshes with the second transmission gear is rotatably connected to the top of the lead screw.

[0008] As a further embodiment of the present invention, a connecting rod is slidably sleeved at the top of the sleeve, and a plurality of bottom rods located at the bottom of the filter frame are fixedly connected to the bottom of the connecting rod. A filter screen is fixedly connected to the bottom of the filter frame, and a protruding rod for lifting the filter screen is fixedly connected to the top of the bottom rod.

[0009] As a further embodiment of the present invention, a limiting plate is fixedly connected to the top of the base frame, and one side wall of the rotating plate is in contact with the side wall of the limiting plate when the rotating plate is in a horizontal state.

[0010] As a further embodiment of the present invention, a brine barrel is provided at the top of the rotating plate, and a limiting frame for restricting the rotation of the brine barrel is fixedly connected to the top of the rotating plate. A transmission gear is provided at the top of the fixed frame, and a brine barrel is provided on one side of the top of the base frame. A side baffle for restricting the sliding of the brine barrel is fixedly connected to the top of the base frame.

[0011] As a further embodiment of the present invention, a transmission roller for sliding the brine barrel is embedded in one side of the top of the rotating plate and the top of the base frame.

[0012] As a further embodiment of the present invention, universal wheels are rotatably connected to all four sides of the bottom of the base frame, and brake pads are provided on the universal wheels. A drive motor for driving the rotating plate is fixedly connected to the top of the transmission frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a flipping mechanism to drive the filter frame in brine, simultaneously achieving both horizontal rotation and vertical movement. The rotation continuously changes the contact position between the filter screen and the brine, preventing impurities from accumulating locally and forming a "filter cake." The vertical movement ensures the filter frame always adapts to the brine level, maximizing the filtration area. Combined with the vibration effect of the lifting rod lifting the filter screen, it can shake off adhering fine impurities in real time, maintaining a stable filter throughput. The device achieves synchronous linkage of "brine barrel flipping - filter frame lifting - filter screen vibration" through transmission belt and gear set: when the drive motor drives the brine barrel to flip and pour, the power is transmitted to the filter mechanism through transmission belt and transmission gear, automatically triggering the lifting and rotation of the filter frame. The whole process does not require manual handling of high-temperature brine barrels or operation of filter components, completely avoiding the risk of scalding when pouring brine at temperatures above 80°C, while improving the brine filtration efficiency. The filter frame is initially positioned at the bottom of the brine tank and gradually rises as brine is poured in, ensuring that most of its structure remains submerged in the brine. This reduces brine splashing at the source. Combined with the flow-guiding effect of the rotating filter frame, the brine passes smoothly through the filter screen, avoiding the impact and splashing phenomenon of traditional tilting filters. This not only reduces brine waste but also lowers the safety threat of high-temperature brine to operators, while preventing environmental pollution caused by splashing impurities.

[0016] Please see Figure 1-9 The present invention provides a technical solution: a brine circulation and filtration device for processing braised chicken, comprising a base frame 1, a transmission frame 3 fixedly connected to the top of the base frame 1, a rotating plate 2 rotatably connected to the inner side of the transmission frame 3, and further comprising: The rotating filter assembly includes several filter frames 12 that are vertically and equidistantly distributed inside the brine tank 25. Several filter frames 12 are fixedly connected to a connecting frame 17. The top of the connecting frame 17 is provided with a flipping mechanism, which is used to drive the connecting frame 17 to rotate horizontally and move vertically. See Figures 1-2 After braising, the chicken is removed from the braising spice barrel 5. The braising spice barrel 5 is placed above the rotating plate 2, and the braising spice barrel 25 is placed above the base frame 1. The rotating plate 2 is then slowly rotated to create… Figure 4 As shown in the diagram, due to the height difference between the first brine container 5 and the second brine container 25, the brine inside the first brine container 5 gradually pours into the second brine container 25 and is filtered layer by layer through multiple filter frames 12 inside the second brine container 25. The mesh size of the filter frames 12 gradually increases, thus increasing the filtration degree. This allows different solids in the brine to be filtered separately. For example, large pieces of material in the brine are filtered by the first filter frame 12, while spices such as Sichuan peppercorns are filtered by the second filter frame 12. Furthermore, as the rotating plate 2 gradually rotates to filter the brine, the rotating mechanism drives the connecting frame 17 to rotate within the second brine container 25, simultaneously sliding upwards horizontally. The purpose of this is to enhance the brine filtration process. A large amount of solid matter will accumulate on the filter frame 12. The debris easily accumulates on the surface of the filter frame 12 to form a "filter cake". This not only reduces the flow rate, but may also cause brine splashing due to uneven pressure. The splashing of high-temperature brine not only wastes brine, but also affects the personal safety of the surrounding staff. By rotating the filter frame 12, the position of contact between the brine and the filter frame 12 is changed, reducing the accumulation of debris on the filter frame 12. At the same time, the filter frame 12 is initially located inside the bottom of the brine tank 25, and rises in height as the brine gradually increases. That is, if splashing occurs, the filter frame 12 will be located inside the brine tank 25 for most of the filtration time, and the splashed brine will not overflow to the outside of the brine tank 25.

[0017] As a further embodiment of the present invention, the flipping mechanism includes a lead screw 16, which is fixed to the top of the connecting frame 17. A sleeve 14 is spirally sleeved on the top of the lead screw 16. A fixing rod 13 is fixedly connected to the top of the fixing frame 2 8. The sleeve 14 is fixed on the fixing rod 13. A fixing frame 1 is fixedly connected to the top of the base frame 1. A fixing frame 2 8 is fixedly connected to one side of the top of the base frame 1. A transmission gear 11 is provided at the top of both the fixing frame 1 7 and the fixing frame 2 8. The two transmission gears 11 are rotatably connected to a transmission belt 2 9. A transmission belt 6 is rotatably connected to the top of the rotating plate 2 at the rotation center and the top of the fixing frame 1 7. A rack 15 that meshes with the transmission gear 2 26 is rotatably connected to the top of the lead screw 16. See Figures 1-5 , Figure 8During the filtration of brine, the rotating plate 2 rotates around the top center, causing the brine barrel 5 to generate... Figure 4 As shown in the diagram, the brine inside the first brine container 5 gradually flows into the second brine container 25. Simultaneously, the rotating shaft at the top of the fixed frame 7 is driven by the transmission belt 6 to rotate synchronously with the rotating plate 2. Through the cooperation of the two transmission gears 11 and the transmission belt 9, the rotating shaft 1 on the fixed frame 7 drives the rotating shaft 2 at the top of the second fixed frame 8 to rotate. The rotating shaft 2 drives the transmission gear 26 to rotate, and the transmission gear 26 drives the rack 15 to slide upward. The rack 15 drives the lead screw 16 to move upward synchronously by a distance L1, as shown in the diagram. Figure 8 As shown, during the upward movement of the lead screw 16, due to the limitation of the sleeve 14, it rotates along the θ direction during the upward movement, causing the filter frame 12 to flip and switch the position in contact with the brine to avoid the accumulation of debris. At the same time, as the volume of brine inside the brine barrel 25 gradually increases, the filter frame 12 gradually rises in height to continuously filter the brine, while preventing the brine from splashing to the outside of the brine barrel 25.

[0018] As a further embodiment of the present invention, a connecting rod 10 is slidably sleeved at the top of the sleeve 14, and a plurality of bottom rods 23 located at the bottom of the filter frame 12 are fixedly connected to the bottom of the connecting rod 10. A filter screen 18 is fixedly connected to the bottom of the filter frame 12, and a protruding rod 24 for lifting the filter screen 18 is fixedly connected to the top of the bottom rod 23. See Figures 6-9 When the rack 15 rises, it drives the connecting rod 10 to rise synchronously, causing the protruding rod 24 at the bottom of the filter screen 18 to rise synchronously with the filter frame 12. As the filter frame 12 rotates, the top of the protruding rod 24 will contact different positions on the same ring of the filter screen 18. The purpose of this is that the protruding filter screen 18 causes the debris attached to the surface to be displaced to the bottom of both sides under the action of gravity, avoiding the accumulation of debris at the contact position with the brine. Moreover, the contact position between the protruding rod 24 and the filter screen 18 is not at the center of the filter screen 18. In this way, during the rotation of the filter frame 12, the protruding rod 24 will lift the filter screen 18 and cause it to swing, thereby cleaning the debris clogging the filter screen 18.

[0019] As a further embodiment of the present invention, a limiting plate 20 is fixedly connected to the top of the base frame 1, and one side wall of the rotating plate 2 is in contact with the side wall of the limiting plate 20 when the rotating plate 2 is in a horizontal state. See Figure 3 The limiting plate 20 restricts the rotation of the rotating plate 2 and restricts the rotation of the rotating plate 2 in a static state, so as to facilitate the displacement of the brine barrel 5 to the top of the rotating plate 2.

[0020] As a further embodiment of the present invention, a brine barrel 5 is provided at the top of the rotating plate 2, a limiting frame 22 for limiting the rotation of the brine barrel 5 is fixedly connected to the top of the rotating plate 2, a transmission gear 26 is provided at the top of the fixing frame 8, and a side baffle 21 for limiting the sliding of the brine barrel 25 is fixedly connected to the top of the base frame 1. See Figure 3 Place the spice barrel 5 on top of the rotating plate 2 and align it with the limiting frame 22. The limiting frame 22 restricts the position of the spice barrel 5, so that when the rotating plate 2 rotates the spice barrel 5, the spice barrel 5 can remain in the position on the rotating plate 2 without changing due to gravity. The side baffle 21 serves as a positioning tool, ensuring that the position of the spice barrel 25 on the base frame 1 is fixed and uniform each time.

[0021] As a further embodiment of the present invention, the top of the rotating plate 2 and one side of the top of the base frame 1 are respectively embedded with transmission rollers 19 for sliding the brine barrel 5. See Figure 3 Both the brine barrel 1 (5) filled with brine and the brine barrel 2 (25) after filtration are quite heavy, making it difficult to slide them directly on the rotating plate 2 and the base frame 1. The transmission roller 19 is used to make them roll for easy loading and unloading.

[0022] As a further embodiment of the present invention, the bottom of the base frame 1 is rotatably connected to all four sides, and the universal wheels are provided with brake pads. The top of the transmission frame 3 is fixedly connected to a drive motor 4 for driving the rotating plate 2 to rotate. The universal wheels facilitate the movement of the base frame 1, and the brake pads keep the base frame 1 stationary during filtration. The drive motor 4 drives the rotating plate 2 to flip over to filter the brine.

[0023] Working principle: The brine inside the brine barrel 1 5 gradually enters the brine barrel 2 25. At the same time, the rotating shaft 1 at the top of the fixed frame 1 7 is driven by the transmission belt 6 to rotate synchronously with the rotating plate 2. Then, through the cooperation of the two transmission gears 11 and the transmission belt 9, the rotating shaft 1 on the fixed frame 1 7 drives the rotating shaft 2 at the top of the fixed frame 2 8 to rotate. The rotating shaft 2 drives the transmission gear 26 to rotate. The transmission gear 26 drives the rack 15 to slide upward. The rack 15 drives the lead screw 16 to move upward synchronously. During the upward movement of the lead screw 16, due to the limitation of the sleeve 14, it rotates during the upward movement, causing the filter frame 12 to flip and switch the position in contact with the brine to avoid the accumulation of debris. At the same time, as the volume of brine inside the brine barrel 2 25 gradually increases, the filter frame 12 gradually rises in height to continuously filter the brine, while preventing the brine from splashing to the outside of the brine barrel 2 25. When the rack 15 rises, it drives the connecting rod 10 to rise synchronously, causing the protruding rod 24 at the bottom of the filter screen 18 to rise synchronously with the filter frame 12. As the filter frame 12 rotates, the top of the protruding rod 24 will contact different positions on the same ring of the filter screen 18. The purpose of this is that the protruding filter screen 18 causes the debris attached to the surface to be displaced to the bottom on both sides under the action of gravity, avoiding the accumulation of debris at the contact position with the brine. Moreover, the contact position between the protruding rod 24 and the filter screen 18 is not at the center of the filter screen 18. In this way, during the rotation of the filter frame 12, the protruding rod 24 will lift the filter screen 18 and cause it to swing, thereby cleaning the debris clogging the filter screen 18.
