Technical Field
[0001] This utility model relates to the technical field of morel mushroom processing equipment, and in particular to a multi-layer circulating hot air drying box for drying morel mushrooms. Background Technology
[0002] Morel mushrooms are a rare edible fungus, rich in various nutrients, and are loved by consumers. Drying is a key step in the processing of morel mushrooms. Its purpose is to remove the moisture from the morel mushrooms, making them easier to store and transport, while preserving their nutrients and flavor to the greatest extent.
[0003] Morel mushrooms need to be dried and dehydrated during processing to meet the requirements for packaging and storage. However, in current drying equipment, morel mushrooms are always on the same heated surface, and they often need to be turned manually when they need to be turned, which results in a waste of manpower and resources.
[0004] An existing patent (publication number: CN221670906U) discloses a morel mushroom processing and drying device. This utility model uses an electric telescopic rod to first retract, causing the extrusion block to move along the extrusion groove. At this time, the sliding plate squeezes the spring, causing the spring to be compressed. When the extrusion block moves to the top of the vertical groove, the spring is no longer subjected to the force from the extrusion block and will quickly rebound to return to its original length. At this time, the extrusion plate will be pushed upward by the spring for a short time, thereby turning the morel mushrooms in the drying box and achieving the beneficial effect of drying the morel mushrooms evenly.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing morel mushroom drying devices still employ a relatively simple hot air drying method. This method cannot ensure that hot air is released simultaneously on the inner and outer layers of the morel mushrooms, resulting in low drying efficiency. Furthermore, due to the inability to heat evenly, the drying effect of the morel mushrooms is poor, often resulting in some areas being over-dried while others are under-dried, which seriously affects the quality of the product.
[0006] To address this, a multi-layer circulating hot air drying box for drying morel mushrooms is proposed. Utility Model Content
[0007] The purpose of this invention is to provide a multi-layer circulating hot air drying box for drying morel mushrooms. This solution addresses the problem that existing morel mushroom drying devices still use a relatively simple hot air drying method. This method cannot allow hot air to be released simultaneously on the inner and outer layers of the morel mushrooms, resulting in low drying efficiency. Furthermore, due to the inability to heat evenly, the drying effect of morel mushrooms is poor, often resulting in some parts being over-dried while others are under-dried, which seriously affects the quality of the product.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer circulating hot air drying box for drying morel mushrooms, including a support, and a drying mechanism is provided on the top of the support;
[0009] The drying mechanism includes a drying box fixedly connected to the top of the support. The front and rear sides of the drying box are cavities. The top and bottom of the drying box have openings. The front and rear sides of the drying box have outer hot air vents. A mesh cylinder is rotatably connected inside the drying box. The mesh cylinder is located inside the outer hot air vents. A drive structure is provided on the right side of the mesh cylinder. An inlet / outlet is provided at the top of the mesh cylinder. The inlet / outlet is located at the bottom of the top opening. An opening / closing mesh plate is slidably connected inside the inlet / outlet. A three-way pipe is connected to the left side of the top of the drying box. A drying hot air fan is connected to the left side of the three-way pipe. An inner drying structure is provided inside the mesh cylinder. The inner drying structure is connected to the three-way pipe.
[0010] Preferably, the inner drying structure includes a connecting pipe connected to the bottom of the three-way pipe, with the right side of the connecting pipe penetrating the left side of the mesh cylinder.
[0011] Preferably, the right side of the connecting pipe is connected to an inner pipe, which is located inside the mesh cylinder.
[0012] Preferably, an inner hot air outlet is provided on the outer side of the inner tube, and a rubber rod is fixedly connected to the outer side of the inner tube.
[0013] Preferably, the driving structure includes a base block fixedly connected to the right side of the support, and a support sleeve fixedly connected to the top of the base block.
[0014] Preferably, a servo motor is bolted to the top of the support sleeve, the servo motor is connected to an external controller, and the output end of the servo motor is fixedly connected to the right side of the mesh cylinder.
[0015] Preferably, a hopper is fixedly connected inside the top opening, and the hopper is located at the top of the discharge port.
[0016] Preferably, the support has an inclined slide plate inside, and a receiving plate is fixedly connected to the front side of the inclined slide plate.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application employs a drying mechanism. When the inlet / outlet is at the top, the opening / closing screen is removed, allowing morel mushrooms to be placed inside the mesh cylinder through the inlet and outlet. The screen is then reinserted, activating the drive mechanism to rotate the mesh cylinder within the drying chamber, causing the morel mushrooms to tumble. A three-way pipe connects to the output of an external drying hot air blower, allowing hot air to enter the cavities on the front and back sides of the drying chamber via the three-way pipe and exit through the outer hot air outlet, drying the morel mushrooms from the outside. Simultaneously, the inner drying structure within the mesh cylinder is also connected to the three-way pipe, releasing hot air from the inside. This method enables the morel mushrooms to be heated and dried simultaneously on both the inner and outer layers during the turning process, effectively solving the problem that existing devices cannot release hot air from the inner and outer layers at the same time, greatly improving drying efficiency. Under the action of the drive structure, the mesh cylinder rotates continuously, and the morel mushrooms change positions constantly during the drying process, resulting in more uniform heating and avoiding over-drying in some areas and under-drying in others. This significantly improves the drying quality of the morel mushrooms. After drying, the discharge port of the mesh cylinder is rotated to the bottom, and the opening and closing mesh plate is pulled out to easily discharge the morel mushrooms. The operation is simple and convenient.
[0019] 2. By setting up supports, this application provides a stable support foundation for the drying mechanism, ensuring that the drying box remains stable during operation and avoiding the impact of shaking or displacement on the drying effect. Its stable support function ensures that the various components inside the drying box, such as the rotating mesh cylinder and the connecting T-pipes, can operate normally, indirectly improving the reliability and stability of the entire device and extending the service life of the equipment.

[0028] 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.
[0029] Please see Figure 1-7 The present invention provides the following technical solution:
[0030] A multi-layer circulating hot air drying box for drying morel mushrooms includes a support 1, and a drying mechanism 2 is provided on the top of the support 1.
[0031] The drying mechanism 2 includes a drying box 21 fixedly connected to the top of the support 1. The front and rear sides of the drying box 21 are cavities. The top and bottom of the drying box 21 are provided with openings 22. The front and rear sides of the drying box 21 are provided with outer hot air outlets 23. A mesh cylinder 24 is rotatably connected inside the drying box 21. The mesh cylinder 24 is located inside the outer hot air outlet 23. A drive structure 25 is provided on the right side of the mesh cylinder 24. A discharge port 26 is provided on the top of the mesh cylinder 24. The discharge port 26 is located at the bottom of the top opening 22. An opening and closing mesh plate 27 is slidably connected inside the discharge port 26. A three-way pipe 28 is connected to the left side of the top of the drying box 21. A drying hot air fan is connected to the left side of the three-way pipe 28. An inner drying structure 29 is provided inside the mesh cylinder 24. The inner drying structure 29 is connected to the three-way pipe 28.
[0032] In this embodiment: By setting up a support 1 and a drying mechanism 2, the support 1 provides stable support for the drying chamber 21, ensuring the stability of the drying chamber 21 during operation and preventing shaking or displacement. This allows the various components inside the drying chamber 21, such as the rotating mesh cylinder 24 and the connected three-way pipe 28, to operate stably, laying a solid foundation for the entire drying process. Then, when preparing to dry morel mushrooms, the discharge port 26 is turned upwards, the opening and closing mesh plate 27 is pulled out, and the morel mushrooms are placed into the mesh cylinder 24 through the opening 22 and the discharge port 26. The opening and closing mesh plate 27 is then inserted back in, and the drive structure 25 is activated, causing the mesh cylinder 24 to rotate inside the drying chamber 21. The morel mushrooms then turn over. At this time, the three-way pipe 28, which is connected to an external drying hot air blower, delivers hot air to the cavities on the front and rear sides of the drying chamber 21, drying the outer layer of morel mushrooms through the outer hot air discharge port 23. Meanwhile, the inner drying structure 29 also receives hot air through the three-way pipe 28 to dry the morel mushrooms from the inside. This achieves simultaneous heating of the inner and outer layers of the morel mushrooms during the turning process, effectively solving the problem that existing drying devices cannot achieve simultaneous drying of the inner and outer layers with hot air, greatly improving drying efficiency. Moreover, the continuous rotation of the mesh cylinder 24 allows the morel mushrooms to constantly change position, resulting in more uniform heating and avoiding uneven drying, thus improving the drying quality of the morel mushrooms. After drying, the discharge port 26 is rotated to the bottom, and the opening and closing mesh plate 27 can be pulled out to easily discharge the morel mushrooms. The operation is simple and convenient. Here, the drying parameters of the drying hot air blower, such as the control method of key parameters like drying temperature and wind speed, are explained. Users can adjust the drying requirements according to the different stages of the morel mushrooms to ensure precise control of the drying process and guarantee the quality of the morel mushrooms.
[0033] Specifically, such as Figure 4 As shown, the inner drying structure 29 includes a connecting pipe 291 connected to the bottom of the three-way pipe 28, with the right side of the connecting pipe 291 penetrating the left side of the mesh cylinder 24.
[0034] Specifically, such as Figure 4 As shown, the right side of the connecting pipe 291 is connected to the inner pipe 292, which is located inside the mesh cylinder 24.
[0035] Specifically, such as Figure 4 As shown, an inner hot air outlet 293 is provided on the outer side of the inner tube 292, and a rubber rod 294 is fixedly connected to the outer side of the inner tube 292.
[0036] In this embodiment: by setting an inner drying structure 29, hot air from the three-way pipe 28 enters the inner pipe 292 through the connecting pipe 291. The inner pipe 292 is located inside the mesh cylinder 24. The inner hot air outlet 293 opened on the outside of the inner pipe 292 allows the hot air transported by the inner pipe 292 to be blown from the inside of the inner pipe 292 to the inner layer of the morel mushrooms, thereby drying the morel mushrooms from the inside. The rubber rod 294 fixedly connected to the outside of the inner pipe 292 helps to stir the rotating morel mushrooms when the mesh cylinder 24 rotates, so that each part of the morel mushrooms can come into full contact with the hot air under the action of the inner hot air, thereby improving the drying quality of the morel mushrooms.
[0037] Specifically, such as Figure 7 As shown, the drive structure 25 includes a bottom block 251 fixedly connected to the right side of the support 1, and a support sleeve 252 fixedly connected to the top of the bottom block 251.
[0038] Specifically, such as Figure 7 As shown, a servo motor 253 is bolted to the top of the support sleeve 252. The servo motor 253 is connected to an external controller, and the output end of the servo motor 253 is fixedly connected to the right side of the mesh cylinder 24.
[0039] In this embodiment: by setting up a drive structure 25, after the servo motor 253 is started by an external controller, its output end drives the mesh cylinder 24 to rotate. Since the mesh cylinder 24 is the carrier for drying morel mushrooms, the rotation of the mesh cylinder 24 causes the morel mushrooms to tumble continuously during the drying process. In this way, all parts of the morel mushrooms can receive the hot air blown from the inner and outer layers more evenly, effectively avoiding the situation of some morel mushrooms being over-dried or under-dried. Moreover, the speed and rotation time of the servo motor 253 can be flexibly adjusted by the controller. According to the actual situation such as the quantity and humidity of the morel mushrooms, the drying process of the morel mushrooms can be precisely controlled, improving drying efficiency and quality, and meeting different drying needs.
[0040] Specifically, such as Figure 2 As shown, a hopper 3 is fixedly connected inside the top opening 22, and the hopper 3 is located at the top of the discharge port 26.
[0041] Specifically, such as Figure 2 As shown, the support 1 has an inclined slide plate 4 inside, and a receiving plate 5 is fixedly connected to the front side of the inclined slide plate 4.
[0042] In this embodiment: by setting up a feeding hopper 3, an inclined slide plate 4, and a receiving plate 5, when feeding morel mushrooms, the morel mushrooms fall directly into the discharge port 26 through the feeding hopper 3 at the top opening 22, and then into the inside of the mesh cylinder 24. The setting of the feeding hopper 3 guides the morel mushrooms to be accurately fed, avoiding the morel mushrooms from scattering, and facilitating operation. After drying, the morel mushrooms are discharged from the discharge port 26 and fall onto the inclined slide plate 4. The inclined design of the inclined slide plate 4 allows the morel mushrooms to automatically slide onto the receiving plate 5. The receiving plate 5 is used to catch the morel mushrooms, preventing them from falling directly to the ground, facilitating collection, reducing the workload of manual collection, and also ensuring the cleanliness and hygiene of the morel mushrooms, thus improving the convenience and efficiency of the entire drying operation.
[0043] Working Principle: In the process of using the multi-layer circulating hot air drying box for morel mushroom drying, the drying box 21 is first placed in a suitable position using the support 1. The support 1 provides stable support for the entire drying mechanism 2, ensuring that the drying box 21 is stable and does not shake during operation, and ensuring the normal operation of each component. When preparing to dry morel mushrooms, the discharge port 26 is rotated to the top, and the opening and closing screen plate 27 is pulled out. The morel mushrooms are placed into the screen cylinder 24 through the discharge port 26 via the hopper 3 of the top opening 22. Then, the opening and closing screen plate 27 is inserted back in. Next, the servo motor 253 in the drive structure 25 is started through the external controller. The servo motor 253 drives the screen cylinder 24 to rotate inside the drying box 21, and the morel mushrooms tumble accordingly. At the same time, the drying hot air blower is connected to the three-way pipe 28 and turned on. The drying hot air blower outputs hot air according to the temperature, wind speed and other parameters set by the user according to different drying stages of the morel mushrooms. The hot air passes through the three-way pipe 28. Part of the morel mushrooms enters the cavities on the front and back sides of the drying chamber 21 and is blown out from the outer hot air outlet 23 to dry the outer layer of morel mushrooms. The other part enters the inner tube 292 through the connecting pipe 291. The inner tube 292 is located inside the mesh cylinder 24. Hot air is blown out from the inner hot air outlet 293 of the inner tube 292 to dry the morel mushrooms from the inside, achieving simultaneous heating and drying of the inner and outer layers of the morel mushrooms. The rubber rod 294 on the outside of the inner tube 292 helps to stir the morel mushrooms, allowing each part to come into full contact with the hot air and be heated more evenly. During the drying process, the user can adjust the speed and rotation time of the servo motor 253 through the controller according to the actual situation to achieve the best drying effect for the morel mushrooms. After drying, the discharge port 26 of the mesh cylinder 24 is rotated to the bottom, and the opening and closing mesh plate 27 is pulled out. The morel mushrooms will fall on the inclined slide plate 4 and automatically slide down the inclined slide plate 4 to the receiving plate 5 for easy collection. The whole operation process is simple and efficient.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
