[0034] Reference Figures 1 to 4 The utility model proposes a multi-stage cleaning device for raw chicken, comprising:

[0035] A conveyor frame 100 having a suspension frame 110;

[0036] a first cleaning tank 200 , which is located below the conveying rack 100 ;

[0037] A first filter plate 300, which is located in the first cleaning tank 200;

[0038] A first cleaning gun 400 is used to rinse the periphery of the raw chicken located in the first cleaning tank 200. Multiple first cleaning guns 400 are arranged opposite to each other, and the gun heads of the first cleaning guns 400 are in a horizontal state;

[0039] Second cleaning tank 500, the raw chicken is transported to the second cleaning tank 500 after passing through the first cleaning tank 200;

[0040] The second filter plate 600 is located in the second cleaning tank 500;

[0041] The second cleaning gun 700 cleans the inside of the raw chicken located in the second cleaning tank 500, and the gun head of the second cleaning gun 700 is in an inclined state.

[0042] After the chickens are plucking and eviscerating, they are cleaned again before final packaging. However, during the plucking and eviscerating processes, feathers and internal organs may not be completely removed in one pass. The eviscerated chickens are transported by a conveyor 100 to the top of a first cleaning tank 200. A first cleaning gun 400 rinses the chicken's exterior, flushing any remaining feathers and dropping them into the first cleaning tank 200. After the chickens are rinsed, the conveyor 100 transports them to the top of a second cleaning tank 500. A second cleaning gun 700 flushes the chicken's interior, flushing any remaining internal organs into the second cleaning tank 500. Because feathers and chicken offal have other uses, such as making feed or crafts, and processing pet food, two separate cleaning pools are set up to collect feathers and offal, respectively. To prevent clogging of the pools, filter plates are installed in each pool to separate the feathers from the wash water and the offal from the wash water. After flushing the exterior and interior, the chicken can undergo a secondary depilation and evisceration, simultaneously completing the cleaning process. This addresses the issue of incomplete chicken treatment during the depilation-evisceration process in existing technologies.

[0043] Specifically, the first cleaning tank 200 is used to receive the remaining feathers washed down by the first cleaning gun 400. The cleaning water and the feathers fall onto the first filter plate 300 of the first cleaning tank 200. The feathers remain above the first filter plate 300. The cleaning water passes through the first filter plate 300 and is received by the first cleaning tank 200.

[0044] To facilitate feather collection, the first filter plate 300 is detachably connected to the first cleaning tank 200. Optionally, a support is provided within the first cleaning tank 200, and the first filter plate 300 is mounted on the support. When a certain amount of feathers have accumulated on the first filter plate 300, the first filter plate 300 can be removed to collect the feathers. Because feathers have a certain degree of adhesion when exposed to water, a large number of feathers on the first filter plate 300 will block the filter mesh of the first filter plate 300, reducing its water flow efficiency. To ensure the water flow efficiency of the first filter plate 300, a larger mesh size is required. At the same time, to prevent feathers from passing through the first filter plate 300, the mesh size of the first filter plate 300 is preferably 18 to 25.

[0045] When the first cleaning tank 200 is provided with the liquid outlet 210, the height of the support member is higher than the liquid outlet 210, so that the first filter plate 300 is higher than the liquid outlet 210. In this case, the first filter plate 300 can not only collect feathers but also prevent feathers from clogging the liquid outlet 210.

[0046] Furthermore, to ensure comprehensive rinsing of the raw chicken's exterior, multiple first cleaning guns 400 are provided, arranged in opposing positions. This means that as the raw chicken is conveyed over the first cleaning tank 200, the multiple first cleaning guns 400 are positioned on either side of the raw chicken to rinse its exterior. The first cleaning guns 400 are connected to a water source and a water pump to achieve a predetermined pressure.

[0047] The second cleaning tank 500 receives the remaining viscera flushed from the raw chicken's cavity by the second cleaning gun 700. These viscera, along with the cleaning water, fall into the second cleaning tank 500 and remain above the second filter plate 600. The cleaning water then passes through the second filter plate 600 and enters the lower portion of the second cleaning tank 500. Since the raw chicken's cavity is typically opened during the evisceration process, flushing can remove any remaining viscera. Furthermore, the raw chicken's internal skeleton allows for high water pressure to be used without damaging the chicken.

[0048] The surface of residual offal is relatively smooth, making it more difficult to collect than feathers. Furthermore, since the offal remaining in the raw chicken cavity is of various types and sizes, the mesh size of the second filter plate 600 is selected to be in the range of 25-35 mesh, with a smaller pore size to prevent offal from getting stuck in the filter holes and making collection difficult.

[0049] Furthermore, to facilitate the collection of residual viscera, the second filter plate 600 is tilted. When residual viscera accumulate on the second filter plate 600 to a certain extent, a tool such as a scraper can be used to collect the viscera along the second filter plate 600. To facilitate the discharge of viscera, a discharge port 510 is provided in the second cleaning tank 500. The discharge port 510 is located at the lower end of the second filter plate 600.

[0050] The axis of the filter holes of the second filter plate 600 is arranged perpendicular to the horizontal plane, so that the second filter plate 600 can be quickly discharged into the water.

[0051] The conveyor rack 100 hangs the raw chicken via the hanging rack 110 . During the hanging process, the feet of the raw chicken are inserted into the cavity 111 , and the two feet are respectively clamped in the two leg grooves 112 to achieve the hanging of the raw chicken.

[0052] The present invention also proposes a raw chicken processing line, which includes a multi-stage cleaning device as described above. Since the processing line adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the above embodiments, which will not be described one by one here.

[0053] It should also be noted that the cleaning device can operate as a standalone structure or as part of a production line to complete the corresponding process. The lengths of the first cleaning tank 200, the second cleaning tank 500, and the conveyor rack 100 can be set according to the specific working environment. In addition, the first cleaning tank 200 and the second cleaning tank 500 are independent structures.

[0054] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
