Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a cylindrical multi-layer turning mushroom drying equipment. Background Technology

[0002] Fresh mushrooms have a high water content, are prone to rotting and spoilage at room temperature, and are difficult to store for long periods and transport over long distances. If fresh mushrooms are not processed in time after harvesting, they may become moldy within 24 hours, which seriously affects economic benefits. By using drying equipment to dehydrate and dry mushrooms, the water content can be reduced to a safe storage range of 12%-15%, which can extend the shelf life of mushrooms.

[0003] In existing technologies, most drying devices use a single air inlet and fixed air vent design. However, most drying devices are multi-layered. A single air inlet results in higher temperatures near the inlet and lower temperatures further away, causing mushrooms closer to the inlet to become scorched and incompletely dried. In the actual processing of mushrooms, they are usually laid directly on the placement layer. Due to the lack of an effective turning device, the mushrooms cannot be heated evenly as ideally. The distance between the mushrooms and the heat source varies at different positions on the placement layer. Mushrooms closer to the heat source heat up faster, while those further away heat up more slowly. Moreover, without a turning device to change the position of the mushrooms, this heating difference persists, causing the temperature difference between different parts of the mushroom to widen, further exacerbating the problem of uneven heating. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical multi-layer turning mushroom drying device to solve the problems mentioned in the background art, such as uneven heating of mushrooms at different distances due to a single air inlet, and the problem that the lack of a turning component would further aggravate uneven heating due to the accumulation of mushrooms.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical multi-layer turning mushroom drying device, including a drying cylinder and support legs installed on the drying cylinder, as well as a first pipe installed on the drying cylinder, a second pipe installed on the first pipe, a lifting component installed on the drying cylinder, a feeding component installed on the lifting component, and a turning component installed on the drying cylinder. The lifting component extends the feeding component outside the drying cylinder, and mushrooms are laid inside the feeding component. The turning component turns the mushrooms inside the feeding component.

[0006] Based on the preferred embodiment of this technical solution, there are several second pipes and several nozzles, and the several second pipes are circular, and the second pipes are distributed sequentially from top to bottom on the first pipe, and the several nozzles are evenly distributed on the second pipes.

[0007] According to the preferred embodiment of this technical solution, the lifting assembly includes a first motor installed at the bottom of the drying cylinder, a first threaded rod fixedly connected to the output end of the first motor, a lifting rod threadedly connected to the first threaded rod, and a top cover fixedly connected to the top of the lifting rod and covering the drying cylinder. The first threaded rod is rotatably connected to the drying cylinder.

[0008] In the preferred embodiment of this technical solution, the drying cylinder has a sliding groove at the corresponding position of the lifting rod, and the lifting rod slides inside the sliding groove.

[0009] In a preferred embodiment of this technical solution, the feeding assembly includes a mounting block fixedly connected to the lifting rod, a first placement disc mounted on the mounting block, a threaded cylinder rotatably connected to the mounting block, a second threaded rod threadedly connected to the threaded cylinder, a slider fixedly connected to the second threaded rod, and a second placement disc mounted on the slider. The rotation of the threaded cylinder to screw out or into the second threaded rod can drive the first placement disc and the second placement disc to move away from or closer to each other.

[0010] In the preferred embodiment of this technical solution, the lifting rod has a guide groove at the corresponding position of the slider, and the slider slides inside the guide groove.

[0011] In a preferred embodiment of this technical solution, the tumbling assembly includes a second motor fixedly connected to the bottom of the drying drum, a first drive rod fixedly connected to the output end of the second motor, a second drive rod slidably connected to the first drive rod, a connecting ring slidably connected to the second drive rod, a first rubber rod fixedly connected to the connecting ring, and a second rubber rod fixedly connected to the first rubber rod. The connecting ring is rotatably connected inside the first and second placement trays. Compared with the prior art, the beneficial effects of this utility model are: 1. Through the first circular pipe, the multi-layer second pipe and the atomizing nozzle, the hot air is evenly diffused in 360°. The temperature difference between each layer of mushrooms is controlled within ±2℃. With the second pipe distributed on the upper and lower sides, the heating of the multi-layer feeding components is ensured to be consistent, thereby improving the qualified rate of mushroom drying and eliminating scorching or undried phenomena.

[0012] 2. The first and second rubber rods, made of rubber, can gently turn the mushrooms, allowing the upper and lower layers of the mushrooms to alternately come into contact with hot air. After drying, the overall moisture content of the mushrooms is effectively reduced. At the same time, the soft rubber rods prevent scratching the surface of the mushrooms and ensure the product's appearance. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 This utility model provides an embodiment of a cylindrical multi-layer turning mushroom drying device, including a drying cylinder 21 and support legs 22 installed on the drying cylinder 21, as well as a first pipe 23 installed on the drying cylinder 21, a second pipe 24 installed on the first pipe 23, a lifting assembly installed on the drying cylinder 21, a feeding assembly installed on the lifting assembly, and a turning assembly installed on the drying cylinder 21. The lifting assembly extends the feeding assembly outside the drying cylinder 21, and mushrooms are laid inside the feeding assembly. The turning assembly turns the mushrooms inside the feeding assembly. The drying cylinder 21 is made of 304 stainless steel, which has good temperature resistance. It can withstand drying temperatures of 80-120℃ for a long time and is corrosion resistant, preventing rust contamination of mushrooms. The support legs 22 are welded from Q235 steel plates and have rubber anti-slip pads at the bottom to enhance the stability of the device and prevent displacement due to vibration during the drying process. The first pipe 23 and the second pipe 24 are both food-grade stainless steel pipes with smooth inner walls that are not easy to accumulate dirt, ensuring that the hot air is clean and free of impurities, meeting the hygiene requirements of food processing. The lifting component can avoid heat loss caused by frequent manual opening of the drying cylinder to pick up and put in materials, reducing energy consumption. A hot air blower can be connected to the first pipe 23 to continuously supply hot air into the first pipe 23, and an exhaust port is opened on the drying cylinder 21.

[0017] Please see Figure 3A further solution based on this embodiment is as follows: several second pipes 24 and nozzles 25 are provided, and the several second pipes 24 are circular. The second pipes 24 are distributed sequentially from top to bottom on the first pipe 23, and the several nozzles 25 are evenly distributed on the second pipes 24. The several second pipes 24 ensure that the hot air covers the entire area of ​​the drying cylinder 21. The nozzles 25 are spiral atomizing nozzles, which can make the hot air diffuse evenly and avoid local overheating. They are compatible with multi-layer feeding components to ensure that the temperature difference of each layer of mushrooms is ≤±2℃, thus solving the problem of "near heat and far cold" caused by the traditional single air inlet.

[0018] Please see Figure 2 A further solution based on this embodiment is as follows: The lifting assembly includes a first motor 31 installed at the bottom of the drying cylinder 21, a first threaded rod 32 fixedly connected to the output end of the first motor 31, a lifting rod 33 threadedly connected to the first threaded rod 32, and a top cover 34 fixedly connected to the top of the lifting rod 33 and covering the drying cylinder 21. The first threaded rod 32 is rotatably connected to the drying cylinder 21. The first threaded rod 32 is made of No. 45 steel with chrome plating, which has strong wear resistance and high thread precision to ensure smooth lifting. The inner side of the top cover 34 is pasted with polyurethane insulation cotton, which can reduce heat loss inside the drying cylinder 21 and improve drying efficiency.

[0019] Please see Figure 2 A further solution based on this embodiment is as follows: the drying cylinder 21 has a sliding groove at the corresponding position of the lifting rod 33, and the lifting rod 33 slides inside the sliding groove. The inner wall of the sliding groove is polished to reduce the frictional resistance when the lifting rod 33 slides, so that the material feeding component extends / retracts more smoothly. The gap between the sliding groove and the lifting rod 33 is controlled at 0.5-1mm, which can both ensure the flexible sliding of the lifting rod and limit its movement to prevent the material feeding component from deviating and colliding with the inner wall of the drying cylinder.

[0020] Please see Figure 4 A further embodiment of this solution is as follows: The feeding assembly includes a mounting block 41 fixedly connected to the lifting rod 33, a first placement plate 42 mounted on the mounting block 41, a threaded cylinder 43 rotatably connected to the mounting block 41, a second threaded rod 44 threadedly connected to the threaded cylinder 43, a slider 45 fixedly connected to the second threaded rod 44, and a second placement plate 46 mounted on the slider 45. The threaded cylinder 43 rotates out or into the second threaded rod 44, which can drive the first placement plate 42 and the second placement plate 46 to move away from or closer to each other. The mounting block 41 is made of aluminum alloy, which is lightweight and has high strength. The first placement plate 42 and the second placement plate 46 are both made of food-grade PP plastic, which is heat-resistant and has a smooth surface, making it less likely for mushrooms to stick together. The threaded cylinder 43 is provided with an external hexagonal block, which is convenient for manual rotation and adjustment. The spacing adjustment range is 5-15cm, which can be flexibly adapted according to the thickness of the mushrooms, avoiding the mushrooms from piling up too thickly and causing the inner layer to dry incompletely.

[0021] Please see Figure 4 A further solution based on this embodiment is as follows: the lifting rod 33 has a guide groove at the corresponding position of the slider 45, and the slider 45 slides inside the guide groove. The cross section of the guide groove is T-shaped and matches the shape of the slider 45. This can prevent the slider from detaching from the lifting rod 33 when sliding, ensuring the second placement plate 46 moves stably. Solid grease is applied to the inner wall of the guide groove to further reduce sliding friction and make the spacing adjustment easier.

[0022] Please see Figure 2 , Figure 5 A further solution based on this embodiment is as follows: The turning assembly includes a second motor 51 fixedly connected to the bottom of the drying cylinder 21, a first drive rod 52 fixedly connected to the output end of the second motor 51, a second drive rod 53 slidably connected to the first drive rod 52, a connecting ring 54 slidably connected to the second drive rod 53, a first rubber rod 55 fixedly connected to the connecting ring 54, and a second rubber rod 56 fixedly connected to the first rubber rod 55. The connecting ring 54 is rotatably connected inside the first placement tray 42 and the second placement tray 46. The first rubber rod 55 and the second rubber rod 56 are made of food-grade silicone, which is soft and elastic, effectively turning the mushrooms without scratching their surface. The gap between the connecting ring 54 and the inner wall of the placement tray is 1-2mm, allowing for smooth rotation without jamming and ensuring no dead angles during turning.

[0023] Working principle: The first motor 31 drives the first threaded rod 32 to rotate, which in turn drives the lifting rod 33 to rise. The lifting rod 33 then drives the feeding assembly to extend beyond the drying cylinder 21. The threaded cylinder 43 is twisted, causing it to rotate out of or into the second threaded rod 44. The second threaded rod 44 drives the slider 45, which in turn drives the second placement tray 46. The distance between the first placement tray 42 and the second placement tray 46 can be adjusted. Mushrooms are then laid on the first and second placement trays. After laying is complete... The first motor 31 flips, and the principle is the same as above, driving the material feeding component to descend back into the drying cylinder 21. Hot air is delivered into the first pipe 23 by the external hot air blower, and then the hot air is evenly dispersed through the second pipe 24 and the nozzle 25. Then the second motor 51 is started to drive the first drive rod 52, the first drive rod 52 drives the second drive rod 53, the second drive rod 53 drives the connecting ring 54, and the connecting ring 54 drives the first rubber rod 55 and the second rubber rod 56. The mushroom is turned up by the first rubber rod 55 and the second rubber rod 56.
