[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] like Figure 1-8 As shown, a food processing meat drying device includes a drying box 1, a sealed box door is hinged on one side of the drying box 1, a hot air circulation mechanism is provided on one side of the drying box 1, a support column 2 is rotatably connected inside the drying box 1, a driving mechanism for rotating the support column 2 is provided at the bottom of the drying box 1, a support plate 3 is provided on the support column 2, and an annular groove 4 is opened on the side wall of the support plate 3, a plurality of rotating shafts 5 are rotatably connected in the annular groove 4, the rotating shafts 5 are rotatably connected to the bottom of the annular groove 4 through bearings, and the plurality of rotating shafts 5 are evenly distributed in the annular groove 4. The bottom of the rotating shaft 5 passes through the support plate 3 and is fixedly connected to a hook 6. A driving assembly for rotating the rotating shaft 5 is provided on the inner walls of both sides of the drying box 1. The number of the support plates 3 and the driving assembly is set to three. The support plate 3 and the driving assembly in the middle position are respectively fixed on the support column 2 and the side wall of the drying box 1. The support plates 3 and the driving assembly on the upper and lower sides are respectively movably connected to the support column 2 and the side wall of the drying box 1. A lifting mechanism is provided in the support column 2 for moving the support plates 3 and the driving assembly on the upper and lower sides up and down.

[0029] The driving mechanism includes a driving groove 7 opened at the bottom of the drying box 1, and a driving motor 8 is fixedly provided on one side of the driving groove 7. The output shaft of the driving motor 8 is fixedly connected to a rotating shaft 9, and the end of the rotating shaft 9 is fixedly sleeved with a first bevel gear 10. The bottom of the support column 2 extends through the driving groove 7 and is fixedly sleeved with a second bevel gear 11. The second bevel gear 11 is meshed with the first bevel gear 10. The bottom of the support column 2 is rotatably connected to the bottom of the driving groove 7. The diameter of the second bevel gear 11 is larger than the diameter of the first bevel gear 10.

[0030] The rotating shaft 9 and the first bevel gear 10 are driven to rotate by the driving motor 8. The first bevel gear 10 engages with the second bevel gear 11 to rotate, and the second bevel gear 11 drives the support column 2 and the support plate 3 to rotate. Since the diameter of the second bevel gear 11 is larger than the diameter of the first bevel gear 10, it plays a decelerating role, so the support column 2 and the support plate 3 can rotate slowly, avoiding the support plate 3 rotating too fast, causing the meat on the bottom hook 6 to be unhooked, or collision between adjacent meats, resulting in surface damage.

[0031] The driving assembly includes a connecting plate 12 that can be moved up and down and connected to the side wall of the drying box 1. The connecting plate 12 is fixedly connected to an annular plate 13, and the annular plate 13 is slidably connected to the annular groove 4. The annular plate 13 is fixedly provided with an annular rack 14 on the side close to the rotating shaft 5. A gear 15 is fixedly sleeved on the rotating shaft 5, and the gear 15 is meshed with the annular rack 14.

[0032] While the support plate 3 drives the rotating shaft 5 to rotate, the gear 15 on the rotating shaft 5 also revolves around the center of the support column 2. The gear 15 continuously engages with the annular rack 14 while revolving, thereby driving the gear 15 and the rotating shaft 5 to rotate. Without the need for an additional driving source, the meat on the hook 6 at the bottom of the rotating shaft 5 can rotate while revolving during drying, so that the meat is heated evenly, thereby improving the efficiency and effect of meat drying.

[0033] Annular grooves 16 are provided on the upper and lower inner walls of the annular groove 4, and annular sliders 17 are fixed on the upper and lower sides of the annular plate 13. The annular sliders 17 are slidably connected in the annular grooves 16 to improve the stability of the annular plate 13 in the annular groove 4 when the support plate 3 rotates.

[0034] The upper and lower inner walls of the drying box 1 are provided with limiting grooves 18, and the limiting grooves 18 are arranged in the vertical direction of the drying box 1. The limiting blocks 19 are slidably connected in the limiting grooves 18, and the limiting blocks 19 are fixedly connected to the side walls of the connecting plate 12. The number of the limiting grooves 18 and the limiting blocks 19 is set to 4, and they are symmetrically arranged on the inner walls of both sides of the drying box 1. The movement trajectory of the connecting plate 12 is limited by the limiting grooves 18 and the limiting blocks 19, so that the connecting plate 12 can only move in the vertical direction, thereby preventing the annular plate 13 slidingly connected to the annular groove 4 from rotating when the support plate 3 rotates, affecting the meshing relationship between the annular rack 14 and the gear 15 on the annular plate 13, and affecting the rotation of the rotating shaft 5 and the hook 6 at the bottom driven by the gear 15.

[0035] The lifting mechanism includes a lifting slot 20 provided in the support column 2, and a bidirectional screw rod 21 is rotatably connected in the lifting slot 20. The top of the bidirectional screw rod 21 passes through the support column 2 and is fixedly connected to a rotating motor 22. The support column 2 passes through the top of the drying box 1 and is rotatably connected to the inner wall of the top of the drying box 1. The rotating motor 22 is fixedly provided on the top of the support column 2. A through slot for the bidirectional screw rod 21 to pass through is provided in the support column 2. A lifting seat 23 is threadedly connected to both sides of the bidirectional screw rod 21. A fixing block 24 is fixedly provided on the side wall of the lifting seat 23. A connecting slot 25 is provided on the side wall of the lifting slot 20. The fixing block 24 passes through the connecting slot 25 and is fixedly connected to the support plate 3. The fixing blocks 24 on the upper and lower sides are respectively fixedly connected to the support plates 3 on the upper and lower sides. The number of the fixing blocks 24 is set to four and is evenly distributed around the support column 2.

[0036] By rotating the motor 22 to drive the bidirectional screw rod 21 to rotate, the lifting seats 23 on the upper and lower sides of the bidirectional screw rod 21 drive the fixed block 24 and the support plate 3 to move in opposite directions. While moving, the support plate 3 drives the driving components on both sides to move up and down synchronously, thereby adjusting the distance between the support plates 3 on the upper and lower sides and the support plate 3 in the middle position, which is suitable for drying meat of different lengths and also convenient for moving the support plates 3 on the upper and lower sides to the middle position, so as to facilitate taking and placing meat hanging on the support plates 3.

[0037] A hydraulic rod 26 is fixedly provided at the bottom of the limit groove 18, and the top of the hydraulic rod 26 is fixedly connected to the limit block 19. When the limit block 19 moves in the limit groove 18, the hydraulic rod 26 synchronously moves a corresponding distance to support the bottom of the limit block 19, thereby improving the stability of the connecting plate 12 fixedly connected to the limit block 19, and further improving the stability of the annular plate 13 in the annular groove 4 when the support plate 3 rotates, thereby ensuring the stability of the meshing connection between the gear 15 on the rotating shaft 5 rotatably connected to the bottom of the annular groove 4 and the annular rack 14 on the side wall of the annular plate 13.

[0038] The hot air circulation mechanism includes an air collecting hood 27 fixedly arranged on the side wall of the drying box 1, a hot air blower 28 is fixedly arranged on the air collecting hood 27, and a ventilation hole connected to the air collecting hood 27 is opened on the side wall of the drying box 1. The air inlet of the hot air blower 28 is fixedly connected with a ventilation pipe 29, and the ventilation pipe 29 extends to one side of the bottom of the drying box 1. The hot air generated by the hot air blower 28 is blown toward the air collecting hood 27. After being dispersed by the air collecting hood 27, the hot air can evenly pass through the ventilation holes and flow into the drying box 1, so that the hot air in the drying box 1 is evenly distributed.

[0039] The support plate 3 is provided with a plurality of ventilation slots 30 , which facilitate the upward and downward circulation of air in the drying box 1 , thereby improving the circulation effect of hot air.

[0040] A temperature sensor 31 is fixedly provided on the inner wall of one side of the drying box 1. The temperature sensor 31 is electrically connected to the hot air blower 28. The temperature inside the drying box 1 is controlled by the temperature sensor 31 to keep the temperature inside the drying box 1 at an appropriate temperature, thereby preventing the temperature inside the drying box 1 from being too high, causing the moisture on the surface of the meat to evaporate rapidly, resulting in surface hardening and forming a hard shell, which hinders the continued evaporation of internal moisture. If the temperature inside the drying box 1 is too low, it will take a long time to remove the moisture, and it will easily increase the risk of microbial growth, affecting the storage stability and safety of the product.

[0041] A controller is fixedly provided on one side of the drying box 1 , and the controller is electrically connected to the driving motor 8 , the rotating motor 22 , the hydraulic rod 26 , the hot air blower 28 and the temperature sensor 31 through wires.

[0042] When in use, according to the length of the meat to be dried, first start the rotating motor 22 to drive the bidirectional screw 21 to rotate, and the lifting seats 23 on the upper and lower sides of the bidirectional screw 21 drive the fixed block 24 and the support plate 3 to move in opposite directions. While the support plate 3 moves, it drives the driving components on both sides to move up and down synchronously, and adjusts the distance between the support plates 3 on both sides and the support plate 3 in the middle position to a suitable position. Hang the meat on the hook 6 under the support plate 3, then start the hot air blower 28 and the drive motor 8, and the drive motor 8 drives the rotating shaft 9 and the first bevel gear 10 to rotate. The first bevel gear 10 engages with the second bevel gear 11 to rotate, and the second bevel gear 11 drives the support column 2 and the support plate 3 to rotate slowly. The support plate 3 drives the rotating shaft 5 and the gear 15 on the rotating shaft 5 to revolve around the center of the support column 2. While revolving, the gear 15 continuously engages with the annular rack 14, thereby driving the gear 15 and the rotating shaft 5 to rotate. Without the need for additional drive, the meat on the hook 6 at the bottom of the rotating shaft 5 can rotate while revolving during drying, so that the meat is heated evenly, thereby improving the efficiency and effect of meat drying.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
