Description

Technical Field

[0001] This invention relates to the field of roast chicken processing production line technology, and in particular to a complete roast chicken processing production line and production method. Background Technology

[0002] Roast chicken, a traditional braised meat product, is beloved by consumers, and the industry is continuously expanding. Automated production lines have gradually replaced traditional manual operations, becoming the mainstream method for mass production of roast chicken. The core processes involved in a roast chicken production line, such as raw material steaming, conveying, feeding, oil soaking, and roasting, all rely on specialized agricultural and sideline food processing equipment. Specifically, the steaming and roasting processes correspond to steaming equipment and food roasting machinery, respectively, within the specialized agricultural and sideline food processing equipment; the oil soaking process involves oil processing and maturation equipment; and conveying and feeding rely on the accompanying material conveying machinery. These devices together constitute a complete production line for the physical and thermal processing of chicken, a primary agricultural product, and therefore fall under the category of specialized agricultural and sideline food processing equipment.

[0003] In existing roast chicken production lines, the feeding process largely relies on manual labor to hook the processed raw materials one by one onto the hooks of the conveyor line. The unloading process also requires manual removal of the finished roast chickens from the hooks. This repetitive and monotonous hooking work is not only physically demanding and prone to errors, but also makes it difficult for workers to keep up with the continuous operation of the production line, becoming a bottleneck restricting production efficiency. Therefore, designing a fully automated roast chicken processing production line that can automatically feed raw materials onto hooks for conveying and automatically unload finished roast chickens to solve these problems is particularly important. Summary of the Invention

[0050] Reference Figures 1-8 A complete production line for roast chicken processing includes: a steaming and cooking device 1, used to cook the raw materials;

[0051] The conveying device 2 is used at the output end of the cooking device 1 to convey raw materials. The conveying device 2 includes a frame 21, a conveyor belt 22 rotatably connected to the frame 21, and a through hole 23 opened on the conveyor belt 22. The support frame 102 is fixedly connected to the frame 21. The cooked raw materials can be conveyed by the conveyor belt 22. The staff put the raw materials from the cooking device 1 onto the conveyor belt 22 and arrange them so that the neck of the raw materials (cooked chicken) faces forward. The conveyor belt 22 is driven by a motor. When the conveyor belt 22 conveys the raw materials, the water inside the raw materials will be discharged through the through hole 23 opened on the conveyor belt 22.

[0052] The conveying guide rail 3 and the lifting structure 4 installed on the conveying guide rail 3 are used to convey the lifting structure 4. The lifting structure 4 is used to load raw materials. The lifting structure 4 includes an air supply module 41, a separation component 42 and a hook 43 installed on the separation component 42. The air supply module 41 is mainly used to supply air to the pneumatic components on the separation component 42. The hook 43 is used to hook the raw materials for conveying. The conveying guide rail 3 adopts existing technology, with a chain and sprocket drive method in conjunction with a guide sprocket. Since this is a relatively mature technology, its working principle and structure will not be described in detail.

[0053] The spraying device 5 is located on one side of the conveying device 2 and is used to spray the raw materials after they have been cooked by the cooking device 1. The spraying device 5 is mainly used to spray and clean the surface of the raw materials (cooked chicken) after they have been cooked by the cooking device 1. The spraying device 5 mainly uses water rinsing, which is existing technology, so its working principle and structure will not be described in detail.

[0054] The drying device 6 is located at the output end of the spraying device 5 and is used to dry the raw materials after they have been sprayed by the spraying device 5. The drying device 6 is mainly used to pre-dry the surface of the raw materials after cleaning. The drying is mainly carried out by hot air drying. The surface of the raw materials is dried as the conveying guide rail 3 conveys the raw materials through the cavity. This is a relatively mature drying technology, so its working principle and structure will not be described in detail.

[0055] The oil-soaking device 7 is located at the output end of the drying device 6 and is used to apply oil to the raw materials after they have been dried by the drying device 6. The oil-soaking device 7 mainly consists of an oil-soaking tank and honey oil or other grease introduced into the oil-soaking tank. The conveying guide rail 3 conveys the raw materials into the oil-soaking tank for oil soaking, so that the surface of the raw materials is coated with honey oil to enhance the taste and flavor of the raw materials.

[0056] The baking device 8, located at the output end of the oiling device 7, is used to bake the raw materials after they have been oiled by the oiling device 7. The baking device 8 and the drying device 7 both use hot air drying and are equipped with a waste heat recovery system to achieve the purpose of waste heat recovery and reuse, thus achieving the effect of energy-saving drying. The conveying guide rail 3 conveys the raw materials to the baking device 8. After heating and baking for a certain period of time, the conveying guide rail 3 conveys the raw materials to the unloading device 9 for unloading. The heating temperature and baking time of the baking device 8 are controlled by the PLC control system. This is a relatively mature technology, so its working principle and structure will not be described in detail.

[0057] The feeding device 9, located at the output end of the baking device 8, is used to feed the raw materials after baking by the baking device 8. Roasted chicken, as a traditional braised meat product, is very popular with consumers, and the industry is constantly expanding. Automated production lines have gradually replaced traditional manual operations, becoming the mainstream method for mass production of roasted chicken. The core processes involved in the roasted chicken production line, such as raw material steaming, conveying, feeding, oil soaking, and baking, all rely on corresponding specialized agricultural and sideline food processing equipment. Specifically, the steaming and baking processes correspond to steaming equipment and food baking machinery in specialized agricultural and sideline food processing equipment, respectively; the oil soaking process belongs to oil processing and maturation equipment; and conveying and feeding rely on the supporting material conveying machinery. These devices together constitute a complete production line for the physical and thermal processing of chicken, a primary agricultural product, and therefore fall under the category of specialized agricultural and sideline food processing equipment.

[0058] The conveying device 2 is equipped with an auxiliary feeding mechanism 10, which includes a support platform 101 and a support frame 102 mounted on the conveying device 2, an intermittent drive assembly 103 mounted on the support frame 102, grooves 104 symmetrically formed on the support platform 101, sliders 105 symmetrically slidably connected to the inner wall of the grooves 104, and a rotating plate 106 connected to the sliders 105. One of the rotating plates 106 has an opening 107, and a rotating shaft 108 is rotatably connected to the rotating plate 106. The intermittent drive assembly 103 is connected to the rotating shaft 108, and a hook 43 is movably connected inside the opening 107. The drive assembly 103 includes a geared motor 1031 mounted on a support frame 102, a driving bevel gear 1032 mounted on the output end of the geared motor 1031, a driven bevel gear 1033 meshing with the outer wall of the driving bevel gear 1032, a transmission shaft 1034 mounted at the center of the driven bevel gear 1033, a cam 1035 symmetrically mounted on the outer wall of the transmission shaft 1034, a lifting plate 1036 abutting against the outer wall of the cam 1035, and a lifting rod 1037 mounted on the lifting plate 1036. A rotating shaft 108 is fixedly connected to the lifting rod 1037. The centerline of the cam 1035 is not collinear with the centerline of the transmission shaft 1034.When cooked ingredients need to be loaded onto hook 43 for conveying, once the ingredients reach the designated position on the support platform 101, the PLC control system drives the reduction motor 1031 to start. The reduction motor 1031 drives the active bevel gear 1032 mounted on its output end to rotate. The active bevel gear 1032 meshes with the driven bevel gear 1033 and drives the driven bevel gear 1033 to rotate. The driven bevel gear 1033 drives the transmission shaft 1034 mounted at its center to rotate. The transmission shaft 1034 drives the two cams 1035 mounted on its outer wall to rotate. The center line of the cams 1035 is not collinear with the center line of the transmission shaft 1034, thus the cams... Cam 1035 rotates eccentrically around drive shaft 1034. When cam 1035 rotates eccentrically, it contacts the lifting plate 1036 on its outer wall and pushes the lifting plate 1036 upward. Since the frame 21 has a lifting groove near the lifting plate 1036, both ends of the lifting plate 1036 can slide on the inner wall of the lifting groove. The lifting groove can restrict the movement direction of the lifting plate 1036, so the lifting plate 1036 moves upward vertically and drives the lifting rod 1037 to rise. Since the frame 21 is equipped with a guide sleeve for guiding the lifting rod 1037, the lifting rod 1037 moves upward vertically. The lifting rod 1037 pushes the rotating shaft 1... 08. Lifting and rotating the rotating plate 106 on both sides causes it to rotate. The rotation of the rotating plate 106 drives the slider 105 to move towards each other on the inner wall of the groove 104, thereby lifting the raw material (the boiled chicken neck) through the two rotating plates 106. The raw material (the boiled chicken body) still remains on the support platform 101. The PLC control system can match the conveying speed of the conveyor belt 22, the intermittent movement speed of the intermittent drive component 103, and the speed of the conveying hook 43 of the conveying guide rail 3. When the rotating plate 106 lifts the raw material (the boiled chicken neck), the hook 43 enters the opening 107 and is conveyed by the conveying guide rail 3. The hook 43 is located at When the raw material (the boiled chicken neck) is below, it comes into contact with the raw material (the boiled chicken neck). Then, the conveying guide rail 3 moves upward, so the hook 43, driven by the conveying guide rail 3, hooks the raw material and moves it upward, thus loading the raw material onto the hook 43. Compared with the existing method that requires manual hanging of the boiled raw material (the chicken neck) onto the hook 43, this device, with the cooperation of the intermittent drive component 103, the lifting structure 4, the conveying guide rail 3, and the conveyor belt 22, can automatically hang the raw material onto the hook 43 for conveying, effectively improving the loading efficiency, reducing the labor intensity of the workers, and improving the overall automation level of the device.

[0059] The cooking device 1 includes a frame 11, a cooking tank 12 mounted on the frame 11, a heating module 13 mounted on the cooking tank 12, a drain outlet 14 located below the cooking tank 12, a perforated plate 15 movably connected to the inner wall of the cooking tank 12, a telescopic cylinder 16 mounted on the frame 11, a through groove 17 located on the side wall of the cooking tank 12, and a plate 18 slidably connected to the inner wall of the through groove 17. The plate 18 is connected to the output end of the telescopic cylinder 16. Frozen chicken is poured into the cooking tank 12, and water is added to the cooking tank 12. The heating module 13 heats the water in the cooking tank 12 to a boil, thawing and cooking the frozen chicken. After cooking, the PLC control system drives the telescopic cylinder 16 to start. The telescopic cylinder 16 drives the plate 18 to move upward. The upward movement of the plate 18 drives the perforated plate 15 to move upward on the inner wall of the cooking tank 12, supporting the cooked raw material. During the upward movement of the plate 18, since the length of the plate 18 is longer than the length of the through groove 17, the plate 18 can block the through groove 17, thereby preventing the boiling water inside the cooking tank 12 from flowing out of the through groove 17. At this time, the perforated plate 15 lifts the raw material, and the raw material is separated from the water inside the cooking tank 12 through the holes and grooves on the perforated plate 15. The water inside the cooking tank 12 can be discharged through the drain outlet 14.

[0060] The separation assembly 42 includes a hollow rod 421 installed below the air supply module 41, a groove 422 formed on one side wall of the hollow rod 421, a moving block 423 slidably connected to the inner wall of the groove 422, a moving rod 424 slidably connected to the inner wall of the hollow rod 421, a fixing plate 425 fixedly connected to the outer wall of the hollow rod 421, and a cylinder 426 installed on the fixing plate 425. The moving rod 424 is fixedly connected to the moving block 423, and the output end of the cylinder 426 abuts against the lower surface of the moving block 423. The feeding device 9 includes a feeding platform 91 and a position sensor 92 installed on the feeding platform 91. When the roasted chicken is conveyed to the feeding platform 91 near the edge via the conveyor rail 3 and the hook 43, the position sensor... Position sensor 92 detects the position of hook 43, which is located at the edge of the feeding platform 91. Position sensor 92 transmits a signal to the PLC control system, which then starts cylinder 426. Cylinder 426 moves its output end downward to separate from the lower surface of moving block 423, releasing the restriction on moving block 423. Simultaneously, under the action of gravity, moving rod 424 and moving block 423 move downward on the inner wall of hollow rod body 421 and the inner wall of groove body 422, respectively, thereby driving hook 43 downward. Hook 43 moves downward at the outer edge of feeding platform 91 and detaches from the roasted chicken product. At this time, the body part of the roasted chicken product falls onto feeding platform 91, and then the staff removes the roasted chicken product from feeding platform 91.

[0061] It also includes a PLC control system; the cooking device 1, conveying device 2, conveying guide rail 3, hanging structure 4, spraying device 5, drying device 6, oil immersion device 7 and baking device 8 are all electrically connected to the PLC control system. The PLC control system can control the operation of the entire production line and monitor the operation status and production information.

[0062] A method for producing roasted chicken, comprising the following steps:

[0063] S1. Pour the raw materials into the cooking device 1 for cooking. Then, use the telescopic cylinder 16, plate 18 and perforated plate 15 to manually feed the cooked raw materials onto the conveying device 2.

[0064] S2, conveying device 2 conveys the cooked raw materials to the support platform 101;

[0065] S3. The auxiliary feeding mechanism 10 cooperates with the conveying guide rail 3 to transfer the raw material to the hook 43 to complete the feeding; the intermittent drive component 103 is started to drive the rotating shaft 108 to move upward. During the upward movement of the rotating shaft 108, the two rotating plates 106 on both sides are pulled to rotate, lifting the raw material. At this time, the hook 43 enters the opening 107 under the conveying action of the conveying guide rail 3 and moves to the bottom of the raw material. Then, driven by the conveying guide rail 3, the hook 43 moves along the upward running trajectory to hook the raw material. After that, the auxiliary feeding mechanism 10 returns to its position.

[0066] S4. Repeat step S3 to load all the raw materials onto hook 43;

[0067] S5. The conveyor rail 3 conveys the raw materials hooked by the hook 43 to the spraying device 5 for spraying.

[0068] S6, the conveyor rail 3 conveys the sprayed raw material to the drying device 6 for drying;

[0069] S7. Conveying guide rail 3 conveys the dried raw material to the oil immersion device 7 for oil immersion.

[0070] S8, the conveyor rail 3 conveys the raw material after oil soaking to the baking device 8 for baking;

[0071] S9. The conveyor rail 3 transports the baked finished product to the unloading platform 91. When the position sensor 92 detects the position of the hook 43, it transmits the signal to the PLC control system. The PLC control system drives the cylinder 426 to start. The output end of the cylinder 426 moves down and disengages from the moving block 423, releasing the restriction on the moving block 423. At the same time, under the action of gravity, the hook 43 moves down and disengages from the finished product, unloading the finished product onto the unloading platform 91.

[0072] S10. The staff will unload the finished products onto the unloading platform 91.

[0073] Working principle: The raw material (frozen chicken) is poured into the cooking tank 12 for cooking. After cooking, the raw material (cooked chicken) is lifted out of the cooking tank 12 by the cooperation of the telescopic cylinder 16 and the perforated plate 15. The operator loads the raw material (cooked chicken) onto the conveyor belt 22 through the perforated plate 15 and places it with the neck of the raw material (cooked chicken) facing forward. The speed of the conveyor belt 22, the conveyor rail 3 and the intermittent drive component 103 are matched by the PLC control system. When the raw material (cooked chicken neck) reaches the designated position on the support platform 101, the intermittent drive component 103 can lift the raw material (cooked chicken neck). At the same time, the hook 43 enters the opening 107 and is located below the raw material (cooked chicken neck). As the hook 43 moves, it hooks the raw material (cooked chicken neck), thus loading the raw material (cooked chicken) onto the hook 43 for conveying. The conveyor rail 3 drives the lifting structure 4. The raw material (cooked chicken) is sequentially passed through a spraying device 5 to clean its surface, a drying device 6 to dry its surface, an oil-soaking device 7 to coat its surface with grease, and a baking device 8 to bake it into a roasted chicken product. Then, the conveying guide rail 3 and the hanging structure 4 transport the roasted chicken product to the unloading device 9. When the position sensor 92 detects the hook 43, it transmits a signal to the PLC control system. The PLC control system drives the cylinder 426 to start. The cylinder 426 drives its output end to move down and disengage from the moving block 423. At this time, under the action of gravity, the hook 43 moves downward and disengages from the roasted chicken product, so that the roasted chicken product falls onto the unloading platform 91. Finally, the worker can remove the roasted chicken product from the unloading platform 91. Compared with the existing technology, this roasted chicken production line can realize the automatic feeding of raw materials to the hook 43 and the automatic unloading from the hook 43, thereby reducing the labor intensity of the workers and effectively improving the automation level of the production line.

[0074] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

9. A method for producing roasted chicken, using the complete roasted chicken processing production line as described in claim 1, comprising the following steps: S1. Pour the raw materials into the cooking device for cooking. The cooked raw materials are then manually fed onto the conveying device using the telescopic cylinder, plate and perforated plate. S2. The conveying device transports the cooked raw materials to the carrying platform; S3. The auxiliary feeding mechanism works in conjunction with the conveyor rail to transfer the raw material to the hook to complete the feeding. The intermittent drive component is started to drive the rotating shaft to move upward. During the upward movement of the rotating shaft, the two rotating plates on both sides are pulled to rotate, lifting the raw material. At this time, the hook enters the opening under the conveyor rail and moves to the bottom of the raw material. Then, driven by the conveyor rail, the hook moves along the upward running trajectory to hook the raw material. After that, the auxiliary feeding mechanism returns to its position. S4. Repeat step S3 to load all the raw materials onto the hook; S5. The conveyor rail transports the raw materials hooked by the hook to the spraying device for spraying; S6.
