[0002] Dried fruits are fruits whose outer skin has dried after ripening. They are further divided into cracked and indehiscent fruits, and most are rich in protein, vitamins, and lipids. Many common dried fruits exist in our lives, such as chestnuts, nutmegs, and nutmegs. Dried fruit foods contain 17 amino acids, including the eight essential amino acids, and are rich in minerals such as manganese, calcium, phosphorus, and potassium, as well as vitamins, carotene, and protein. They are also rich in monounsaturated fatty acids, oleic acid, and magnesium.
[0003] In existing technologies, operators mostly use manual static drying when drying dried fruits and vegetables. This method may result in insufficient drying. Manually turning the dried fruits and vegetables over not only increases the workload of the operators but also reduces the drying efficiency. Furthermore, the dried fruits and vegetables may be affected by birds during the drying process, which could contaminate them and affect their quality, thus hindering the drying process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1
[0025] Reference Figure 1-5 A drying device for processing dried fruit food includes a circular drying plate 1. A drive motor 2 is provided at the middle position of the lower surface of the circular drying plate 1. A drive rod 3 is provided at the power output end of the drive motor 2. A fixing block 4 is fixedly connected to the upper surface of the drive rod 3. A circular sleeve 31 is sleeved on the outer surface of the drive rod 3, and the circular sleeve 31 is fixedly connected to the middle position of the upper surface of the circular drying plate 1.
[0026] Two strip sleeves 5 are fixedly connected to both sides of the fixing block 4. Four stirring rods 6 are fixedly connected to the lower surface of the two strip sleeves 5. The side of the two strip sleeves 5 away from the fixing block 4 is provided with a guide wheel 8 through a pin 7. The drive motor 2 drives the drive rod 3 to rotate. Since the circular sleeve 31 is fixed on the drying board 1, the drive rod 3 can rotate freely around the central axis. At the same time, the fixing block 4 drives the strip sleeves 5 on both sides to make a circular motion. When the stirring rods 6 rotate with the strip sleeves 5, they can initially stir the dried fruit on the drying board to avoid accumulation.
[0027] An annular sleeve 9 is fixedly connected to the edge of the upper surface of the circular drying board 1. An annular groove 10 is opened at the top of the inner wall of the annular sleeve 9, and the guide wheel 8 is located inside the annular groove 10. The annular sleeve 9 is fixed to the edge of the circular drying board 1 and serves as the physical carrier of the guide track. The annular groove 10 is opened at the top of the inner wall of the annular sleeve 9, and its width is greater than the diameter of the guide wheel 8, ensuring that the guide wheel 8 can roll freely in the groove but cannot detach. The guide wheel 8 is suspended from the end of the strip sleeve 5 by a pin 7, and its outer surface is in close contact with the groove wall of the annular groove 10 to form a mechanical constraint.
[0028] A fixing post 11 is fixedly connected to the upper surface of the fixing block 4. A blocking ring 12 is fixedly connected to the upper surface of the fixing post 11. A threaded post 13 is fixedly connected to the upper surface of the blocking ring 12. A retaining ring 14 is threadedly connected to the outer surface of the threaded post 13. An arc-shaped rod 15 is fixedly connected to the outer surface of the retaining ring 14. A blocking mesh 16 is fixedly connected to the outer surface of the arc-shaped rod 15. A fixing bottom ring 17 is fixedly connected to the bottom end of the arc-shaped rod 15. A limiting threaded cylinder 18 is threadedly connected to the outer surface of the threaded post 13, and the limiting threaded cylinder 18 is located at the retaining ring 14. Above, the top of the threaded column 13 is machined with external threads, which serve as the motion guide for the retaining ring 14 and the limiting threaded cylinder 18. Its core function is to convert rotational motion into axial displacement. The inner wall is machined with matching threads, which can move up and down along the threaded column 13 by rotation. The outer side is connected to the arc-shaped rod 15, which is the actuator for adjusting the height of the blocking net 16. The inner wall thread of the limiting threaded cylinder 18 matches the threaded column 13 and is installed above the retaining ring 14. By tightening, the retaining ring 14 can be pressed to prevent it from loosening or shifting under equipment vibration or material impact.
[0029] Furthermore, the barrier net 16 and the arc-shaped rod 15 can effectively prevent birds from entering the inside of the annular sleeve 9 to peck at the dried fruit, thereby preventing birds from contaminating the quality of the dried fruit products;
[0030] A battery 32 is installed in the middle of the upper surface of the two strip sleeves 5. A second drive motor 19 is installed on the upper surface of the two strip sleeves 5. A second drive rod 20 is installed at the power output end of the second drive motor 19. A drive wheel 21 is fixedly connected to the lower surface of the second drive rod 20. A movable rod 22 is fixedly connected to the lower surface of the drive wheel 21. A first transmission wheel 24 is connected to the outer surface of the drive wheel 21 through a first transmission belt 23. A second transmission wheel 25 is installed on the lower surface of the first transmission wheel 24. Movable rods 26 are installed inside both the first transmission wheel 24 and the second transmission wheel 25. The rotation of the first drive motor 2 can drive the fixed block 4 and the strip sleeves 5 to revolve around the center of the circular drying board 1, so that the stirring rod 6 can perform circumferential stirring and cover the entire drying surface.
[0031] The outer surface of the second transmission wheel 25 is connected to the third transmission wheel 28 via the second transmission belt 27. The interior of the third transmission wheel 28 is equipped with a third movable rod 29. The lower surfaces of the first movable rod 22, the second movable rod 26, and the third movable rod 29 are all fixedly connected with fan blades 30. When the fan blades 30 rotate, they push the air to form an airflow. The airflow direction can be designed to be upward or outward, which accelerates the air circulation on the surface of the drying board, removes moisture from the dried fruit, and, combined with the turning effect of the stirring rod 6, achieves the dual effects of physical turning and airflow drying, thereby improving drying efficiency and uniformity.
[0032] Most existing technologies use manual static drying. When using static drying to dry dried fruits and vegetables, the dried fruits and vegetables may not be dried sufficiently. If the dried fruits and vegetables are turned over manually, it will not only increase the workload of the operators, but also reduce the drying efficiency. In addition, the dried fruits and vegetables may be affected by birds during the drying process, which may contaminate the dried fruits and vegetables and affect the quality of the products, which is not conducive to the drying work.
[0033] Place the circular drying board 1 stably in the open air or drying room. Adjust the height of the blocking net 16 by rotating the retaining ring 14 along the threaded post 13 according to the size of the dried fruit particles. Then, use the limiting threaded cylinder 18 to fix the position and prevent shaking. Spread the dried fruit evenly on the circular drying board, ensuring the thickness does not exceed the position of the fan blade 30. Start the drive motor 2, which drives the fixed block 4 to rotate via the drive rod 3. The fixed block 4 drives the two side strip sleeves 5 to rotate synchronously, and the stirring rod 6 on the lower surface stirs the dried fruit, causing it to tumble. The guide wheel 8 at the end of the strip sleeve 5 rolls within the annular groove 10 of the annular sleeve 9, providing radial support and ensuring smooth rotation of the strip sleeve 5, preventing the device from shaking or the dried fruit from spilling due to centrifugal force.
[0034] While rotating, the fixed column 11, the retaining ring 14, the arc rod 15, the barrier net 16 and the fixed bottom ring 17 will also rotate together with the power of the drive motor 2, which can drive away birds and prevent birds from entering the inside of the annular sleeve 9 to peck at the dried fruit, thereby preventing birds from contaminating the quality of the dried fruit food.
[0035] Then, the running time of drive motor 12 can be set according to the characteristics of dried fruit to ensure that all sides of the dried fruit are evenly contacted for drying and to prevent localized mold growth or uneven drying. When drive motor 29 is turned on, it drives drive wheel 21 to rotate through drive rod 20. Drive wheel 21 drives drive wheel 24 and drive wheel 25 to rotate through drive belt 23. Drive wheel 28 is then driven through drive belt 27. Movable rod 12, movable rod 26, and movable rod 39 rotate synchronously. The fan blade 30 at the lower end rotates at high speed to generate airflow, blowing on the surface of the dried fruit and accelerating moisture evaporation. Drive motor 29 is powered by battery 32 on strip sleeve 5, supporting outdoor use in scenarios without power.
[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
