Description

Technical Field

[0001] This invention relates to the field of nut drying and processing technology, specifically to a nut drying apparatus and drying method. Background Technology

[0002] Nut drying equipment is specialized equipment designed to reduce the moisture content of nuts (such as walnuts, almonds, cashews, pistachios, and peanuts) to achieve freshness, mold prevention, and ease of storage and subsequent processing. Its core principle is to gently remove moisture by controlling temperature, airflow, and time, while simultaneously preserving the nuts' color, flavor, and nutrients. These devices are used in large-scale production settings such as food processing plants and roasted nut companies, and mainly include multi-layer mesh belt dryers, hot air circulating ovens, microwave drying equipment, and belt dryers.

[0003] In existing mesh belt nut dryers, most lack a material-leveling mechanism during actual drying operations. Nuts fall directly from the feed hopper onto the conveyor belt, failing to be effectively dispersed, leading to uneven distribution and significant differences in material thickness. Thicker areas retain moisture, while thinner areas are prone to over-drying, resulting in poor overall drying uniformity. Some nuts have insufficient moisture content, while others are over-roasted, severely impacting product quality and hindering subsequent storage and processing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a nut drying device and drying method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A nut drying device includes a device body, a feeding hopper at the top of the device body, a discharge port at the bottom of one end of the device body, and a drying mesh belt and a conveying mesh belt rotatably mounted inside the device body via two sets of drive shafts. The bottom of the feeding hopper is provided with a toggle mechanism for quickly drying nuts on the top of the drying mesh belt, and both ends of the top of the drying mesh belt and the conveying mesh belt are provided with a baffle mechanism to prevent nuts from falling off. The top of the device body is equipped with two fixed plates, each with a first sliding groove at its top. Each of the two first sliding grooves has a first slider installed inside, and each of the two first sliders has a movable plate installed at its top. Both movable plates are connected to the feed hopper via two first electric telescopic rods set at the top. The actuating mechanism includes two fixed rods installed at the bottom of the feed hopper. A second sliding groove is provided on the outer wall of the side of the two fixed rods that are close to each other. A second slider is installed inside the two second sliding grooves. A fixed frame is installed between the two second sliders. Two rubber scrapers are installed on the top of the two fixed rods. The material blocking mechanism includes a first baffle and a second baffle set at the top of both ends of the drying mesh belt and the conveyor mesh belt. Two connecting rods are installed on the outer walls of the two first baffles and the two baffles on opposite sides. Motors are installed on both outer walls of the device body. Lead screws are installed at the output ends of the two motors. Moving frames are threaded onto the outer walls of the two lead screws. The two moving frames are respectively connected to the two connecting rods that are close to each other.

[0006] Optionally, a moving groove is provided at the center of the top of the device body, and a shielding curtain is installed at both ends of the top of the device body. A connecting plate is installed at the end of the two shielding curtains that are close to each other. Guide grooves are provided on both sides of the moving groove at the top of the device body. Two guide blocks are installed inside each of the two guide grooves. The two connecting plates are connected to the two guide blocks that are close to each other. The two connecting plates are magnetically attracted to the feed hopper through internally preset magnet blocks.

[0007] Optionally, an emergency discharge port is provided at the end of the device body away from the discharge port. A rotating plate is rotatably installed inside the emergency discharge port. A notch is provided at the top of the rotating plate. Two second electric telescopic rods are installed inside the notch. The telescopic ends of the two second electric telescopic rods are jointly installed with an abutment plate.

[0008] Optionally, a limiting plate is rotatably installed inside the device body near the emergency outlet, with the bottom end of the limiting plate abutting against the outer wall of the drying mesh belt.

[0009] Optionally, a toggle plate and a smoothing plate are rotatably mounted inside the fixed frame. A brush is mounted on the end of the smoothing plate away from the rotating part. The smoothing plate has multiple through slots that are adapted to the feeding teeth inside the toggle plate.

[0010] Optionally, each of the two second baffles has a storage groove inside, and each of the two storage grooves has a third sliding groove on its inner bottom surface. Each of the two third sliding grooves has a third slider installed inside, and each of the two third sliders has a blower head connected to its top via a third electric telescopic rod. Each of the two second baffles has a cover plate rotatably installed on its top for sealing the storage groove, and each of the rotating parts at both ends of the cover plate has a torsion spring fitted on its surface.

[0011] Optionally, a nut drying method is applied to the drying apparatus described above, and the drying method further includes the following steps: Step 1: First, control the extension and retraction ends of multiple first electric telescopic rods to reduce the distance between the bottom of the feeding hopper and the drying mesh belt. After the workers put the nuts to be dried into the inside of the feeding hopper, as the two first sliders move back and forth in the corresponding first chute, the feeding hopper moves back and forth on the top of the device body, so that the nuts are slowly and evenly discharged from the bottom of the feeding hopper to the top of the drying mesh belt. Step 2: After the nuts fall to the top of the drying mesh belt, the preset drying equipment inside the control device is activated, allowing hot air to pass through the drying mesh belt and circulate inside the device to slowly dry the nuts placed on top of the drying mesh belt. Step 3: During the drying process of the nuts at the top of the drying mesh belt, the control plate rotates downwards to a vertical position inside the fixed frame. As multiple first electric telescopic rods drive the control plate downwards to abut against the top of the drying mesh belt, two first sliders move back and forth inside the corresponding first grooves, driving the feed hopper and the control plate to move back and forth together, so that the control plate moves horizontally back and forth, automatically moving the nuts at the top of the drying mesh belt. In conjunction with the two second sliders moving back and forth inside the corresponding second grooves, the position of the control plate is moved vertically to adjust the position, so that the control plate can move the nuts at the top of the drying mesh belt comprehensively. Step 4: After the agitator moves the nuts on the top of the drying mesh belt, control the agitator to rotate upwards to reset, and control the smoothing plate to rotate downwards from the inside of the fixed frame to a vertical position. This allows the smoothing plate to repeat the working steps of the agitator in Step 3 above. The brush at the end away from the rotating part of the smoothing plate is used to flatten the nuts on the top of the drying mesh belt, controlling the thickness of the evenly spread material on the top of the drying mesh belt, so that the overall thickness of the nut layer on the top of the drying mesh belt is uniform.

[0012] The beneficial effects of this invention are: 1. In this invention, the feeding hopper can move back and forth on the top of the device body to evenly place the nuts inside on the top of the drying mesh belt, achieving initial flattening of the nuts; then, through the set toggle mechanism, the nuts on the top of the drying mesh belt are automatically toggleed, so that the nuts piled up in the middle of the top of the drying mesh belt are dispersed to both sides, solving the problems of uneven material distribution and accumulation and blockage of nuts during the drying process on the top of the drying mesh belt, and can gently break up damp and clumped nuts, thereby improving the drying efficiency of nuts on the top of the drying mesh belt.

[0013] 2. In this invention, after the agitator moves the nuts on the top of the drying mesh belt, it can be controlled to rotate upwards to reset, and the smoothing plate can be controlled to rotate downwards from the inside of the fixed frame to a vertical state. This allows the smoothing plate to repeat the working steps of the agitator, and with the help of the brush set at the end away from the rotating part, the nuts on the top of the drying mesh belt are spread out. This controls the thickness of the material evenly spread on the top of the drying mesh belt, making the overall thickness of the nut layer on the top of the drying mesh belt uniform, and further improving the subsequent drying efficiency of the nuts.

[0014] 3. In this invention, because the surface of the nuts to be dried contains moisture, they are prone to clogging as they are discharged downwards from the inside of the feed hopper to the top of the drying mesh belt. At this time, a rotating agitator inside the fixed frame can be used to stir and disperse the nuts that are clogged at the bottom of the feed hopper during rotation. This facilitates the automatic handling of the clogging problem at the bottom of the feed hopper, ensuring that the feed hopper can quickly discharge the nuts downwards to the top of the drying mesh belt for drying. This avoids the problem of nuts clogging inside the feed hopper, which would affect the drying efficiency of the nuts.

[0015] 4. In this invention, if the nuts are dried at the top of the drying mesh belt, and a malfunction in the related drive motor causes the drying mesh belt to stop rotating and conveying the nuts downwards, in order to prevent the nuts from remaining inside the device for a long time and being affected by the high temperature and humidity environment inside the device, causing the nuts to quickly become damp, moldy, hot, rancid, and clump together, they must be removed quickly in an emergency. At this time, the blowers inside the two second baffles can be used to loosen the nuts adhering to the drying mesh belt and embedded in the mesh, so that they detach from the top of the drying mesh belt, breaking the adhesion and clumping between the nuts and between the nuts and the drying mesh belt. The nuts are no longer sticking to the surface of the drying mesh belt. Then, with the cooperation of the relevant components of the actuating mechanism, all the nuts at the top of the drying mesh belt are discharged outwards from the emergency discharge port. This achieves the effect of quickly discharging the dried nuts in the event that the drying mesh belt cannot rotate, avoiding the problem of nuts remaining inside the device for a long time and affecting the quality of the nuts.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-12 A nut drying device includes a device body 1, with a feeding hopper 2 at the top and a discharge port 3 at the bottom of one end. Inside the device body 1, a drying mesh belt 12 and a conveyor mesh belt 13 are rotatably mounted via two sets of drive shafts 11. The bottom of the feeding hopper 2 is equipped with a toggle mechanism for rapidly drying nuts on the top of the drying mesh belt 12. Both ends of the drying mesh belt 12 and the conveyor mesh belt 13 are equipped with baffle mechanisms to prevent nuts from falling. Two first drive motors are pre-installed on one side of the outer wall of the device body 1. The output ends of the two first drive motors are connected to one end of the corresponding drive shaft 11, thereby driving the corresponding drive shaft 11 to rotate, which in turn drives the drying mesh belt 12 and the conveyor mesh belt 13 to rotate inside the device body 1. Two fixed plates 4 are installed on the top of the device body 1. Each fixed plate 4 has a first sliding groove 8 on its top. A first slider 19 is installed inside each of the two first sliding grooves 8. A movable plate 20 is installed at the top of each of the two first sliders 19. The two movable plates 20 are connected to the feeding hopper 2 through two first electric telescopic rods 21 set on the top. A first linear motor is preset inside each of the two first sliding grooves 8. The two first linear motors can drive the two first sliders 19 to move back and forth inside the corresponding first sliding grooves 8. In turn, they drive the two movable plates 20, the two first electric telescopic rods 21 and the feeding hopper 2 to move back and forth on the top of the device body 1 for adjustment. This allows the feeding hopper 2 to evenly discharge the nuts downward to the top of the drying mesh belt 12 for drying during the back and forth movement. During the extension and retraction of the two first electric telescopic rods 21, the feeding hopper 2 can move up and down on the top of the device body 1 for adjustment.

[0021] The actuating mechanism includes two fixed rods 22 installed at the bottom of the feed hopper 2. The outer wall of the two fixed rods 22 that are close to each other is provided with a second slide groove 24. A second slider 25 is installed inside the two second slide grooves 24. A fixed frame 26 is installed between the two second sliders 25. Two rubber scrapers 23 are installed on the top of the two fixed rods 22. A second linear motor is preset inside the two second slide grooves 24. The two second linear motors can drive the two second sliders 25 to move back and forth inside the second slide grooves 24, thereby driving the fixed frame 26 to move back and forth between the two fixed rods 22 for adjustment.

[0022] The material blocking mechanism includes a first baffle 32 and a second baffle 33 located at the top of both ends of the drying mesh belt 12 and the conveyor mesh belt 13. Two connecting rods 7 are installed on the outer walls of the two first baffles 32 and the two second baffles 33 on their opposite sides. Motors 34 are installed on the outer walls of both sides of the device body 1. Lead screws 35 are installed at the output ends of both motors 34. Moving frames 6 are threaded onto the outer walls of both lead screws 35, and each moving frame 6 is connected to its adjacent connecting rod 7. After starting, the two motors 34 drive the corresponding lead screws 35 to rotate, thereby moving the two moving frames 6 back and forth on both sides of the device body 1. As the moving frames 6 move, the corresponding first baffles 32 and second baffles 33 can be moved and adjusted on top of the drying mesh belt 12 and the conveyor mesh belt 13 via the two connecting rods 7.

[0023] As a technical optimization of the present invention, a movable groove 16 is provided at the center of the top of the device body 1. A shielding curtain 5 is installed at both ends of the top of the device body 1. A connecting plate 18 is installed at the end of each shielding curtain 5 that is close to each other. Guide grooves 15 are provided on both sides of the top of the device body 1 at the movable groove 16. Two guide blocks 17 are installed inside each guide groove 15. Each connecting plate 18 is connected to its adjacent guide blocks 17. Both connecting plates 18 are magnetically attracted to the feed hopper 2 through internally preset magnets. After the two connecting plates 18 are magnetically attracted to the outer walls of both sides of the feed hopper 2, as the feed hopper 2 moves back and forth inside the movable groove 16, the two shielding curtains 5 can be adjusted back and forth on the top of the device body 1, ensuring that the two shielding curtains 5 do not affect the feed hopper 2 while also providing a sealing and protective effect on the movable groove 16.

[0024] As a technical optimization of the present invention, an emergency discharge port 9 is provided at the end of the device body 1 away from the discharge port 3. A rotating plate 10 is rotatably installed inside the emergency discharge port 9. A notch is provided at the top of the rotating plate 10. Two second electric telescopic rods 30 are installed inside the notch. The telescopic ends of the two second electric telescopic rods 30 are jointly installed with an abutment plate 31. A second drive motor is pre-installed on one side of the outer wall of the device body 1. The output end of the second drive motor is connected to the rotating part of one end of the rotating plate 10, thereby driving the rotating plate 10 to rotate and adjust inside the emergency outlet 9. During the extension and retraction adjustment process, the extension and retraction ends of the two second electric telescopic rods 30 can drive the abutment plate 31 to extend and retract inside the notch. When the rotating plate 10 is in a vertical position inside the emergency outlet 9, the extension of the extension and retraction ends of the two second electric telescopic rods 30 pushes the abutment plate 31 to be inserted into the slot at the top of the emergency outlet 9, so as to assist in limiting and fixing the position of the rotating plate 10. A cleaning brush with short bristles is installed at the end of the abutment plate 31 away from the two second electric telescopic rods 30, so that after the rotating plate 10 drives the abutment plate 31 to rotate and adjust, the cleaning brush abuts against the outer wall of the drying mesh belt 12. As the drying mesh belt 12 rotates, it is convenient to clean the nut shell debris on the surface of the drying mesh belt 12.

[0025] As a technical optimization of the present invention, a limiting plate 14 is rotatably installed inside the device body 1 near the emergency outlet 9, with the bottom end of the limiting plate 14 abutting against the outer wall of the drying mesh belt 12. A third drive motor is preset on one side of the outer wall of the device body 1, and the output end of the third drive motor is connected to the rotating part of one end of the limiting plate 14, thereby driving the limiting plate 14 to rotate and adjust inside the device body 1. As the limiting plate 14 rotates away from the drying mesh belt 12, the drying mesh belt 12 rotates clockwise, allowing the dried nuts at its top to be discharged downwards to the top of the conveyor mesh belt 13 for outward output.

[0026] As a technical optimization of the present invention, a toggle plate 27 and a smoothing plate 28 are rotatably mounted inside the fixed frame 26. A brush 29 is mounted on the end of the smoothing plate 28 away from the rotating part. The smoothing plate 28 has multiple through slots that match the feeding teeth inside the toggle plate 27. Two fourth drive motors are preset inside the fixed frame 26. The output ends of the two fourth drive motors are respectively connected to the rotating parts at one end of the toggle plate 27 and the smoothing plate 28, thereby driving the toggle plate 27 and the smoothing plate 28 to rotate and adjust inside the fixed frame 26.

[0027] As a technical optimization of the present invention, each of the two second baffles 33 has a storage groove inside, and each of the two storage grooves has a third sliding groove 37 on its inner bottom surface. Each of the two third sliding grooves 37 has a third slider 39 installed inside, and each of the two third sliders 39 has a blower head 38 connected to its top end via a third electric telescopic rod 40. Each of the two second baffles 33 has a cover plate 36 rotatably installed on its top for sealing the storage groove, and each of the rotating parts at both ends of the two cover plates 36 is fitted with a torsion spring. Each of the two third slide grooves 37 is equipped with a third linear motor. The two third linear motors can drive the corresponding third sliders 39 to move back and forth inside the third slide grooves 37, thereby driving the two third electric telescopic rods 40 and the blower head 38 to move back and forth and adjust inside the storage slot. After the telescopic end of the third electric telescopic rod 40 is extended, it can push the blower head 38 to move upward, thereby pushing the cover plate 36 to rotate upward and open. As the telescopic end of the third electric telescopic rod 40 retracts and returns to its original position, the cover plate 36 loses the push of the blower head 38 and, with the help of the elastic reset of the torsion spring, drives the cover plate 36 to be repositioned on the top of the second baffle 33.

[0028] As a technical optimization of the present invention, a nut drying method is provided, which is applied to the drying apparatus described above, and the drying method further includes the following steps: Step 1: First, control the extension and retraction ends of multiple first electric telescopic rods 21 to reduce the distance between the bottom end of the feeding hopper 2 and the drying mesh belt 12. After the staff puts the nuts to be dried into the inside of the feeding hopper 2, as the two first sliders 19 move back and forth in the corresponding first slide grooves 8, the feeding hopper 2 moves back and forth on the top of the device body 1, so that the nuts are slowly and evenly discharged from the bottom end of the feeding hopper 2 to the top of the drying mesh belt 12. Step 2: After the nuts fall to the top of the drying mesh belt 12, the preset drying equipment inside the control device body 1 is activated, so that hot air can pass through the drying mesh belt 12 and circulate inside the device body 1 to slowly dry the nuts placed on the top of the drying mesh belt 12. Step 3: During the drying process of the nuts at the top of the drying mesh belt 12, the control plate 27 rotates downwards and becomes vertical inside the fixed frame 26. As multiple first electric telescopic rods 21 drive the plate 27 downwards to abut against the top of the drying mesh belt 12, the two first sliders 19 move back and forth inside the corresponding first slide groove 8, driving the feed hopper 2 and the plate 27 to move back and forth together, so that the plate 27 moves horizontally back and forth, automatically moving the nuts at the top of the drying mesh belt 12. In conjunction with the two second sliders 25 moving back and forth inside the corresponding second slide groove 24, the position of the plate 27 is moved vertically to adjust the position, so that the plate 27 can move the nuts at the top of the drying mesh belt 12 comprehensively. Step 4: After the agitator plate 27 moves the nuts on the top of the drying mesh belt 12, control the agitator plate 27 to rotate upward and reset, and control the smoothing plate 28 to rotate downward from the inside of the fixed frame 26 to a vertical state, so that the smoothing plate 28 repeats the working steps of the agitator plate 27 in Step 3 above. With the help of the brush 29 set at the end away from the rotating part, the nuts on the top of the drying mesh belt 12 are spread out, and the thickness of the nuts spread evenly on the top of the drying mesh belt 12 is controlled, so that the overall thickness of the nut layer on the top of the drying mesh belt 12 is uniform.

[0029] In this invention, when the user uses the device, first, the toggle plate 27 and the flat plate 28 inside the fixed frame 26 are rotated downwards together to avoid blocking the bottom opening of the feed hopper 2. Then, the telescopic ends of the multiple first electric telescopic rods 21 are retracted downwards, so that the distance between the bottom of the feed hopper 2 and the drying mesh belt 12 is reduced. After the worker puts the nuts to be dried into the feed hopper 2, as the two first sliders 19 move back and forth in the corresponding first slide grooves 8, the feed hopper 2 moves back and forth on the top of the device body 1, so that the nuts are slowly and evenly discharged from the bottom of the feed hopper 2 to the top of the drying mesh belt 12, initially achieving the effect of the nuts to be dried being spread flat on the top of the drying mesh belt 12.

[0030] As the nuts fall onto the top of the drying mesh belt 12, the first baffles 32 are provided at both ends of the top of the drying mesh belt 12, and a limiting plate 14 is provided inside the device body 1, which can effectively prevent the nuts falling from the edge of the drying mesh belt 12.

[0031] After the nuts fall onto the top of the drying mesh belt 12, the preset drying equipment inside the controllable device body 1 is activated, allowing hot air to pass through the drying mesh belt 12 and circulate inside the device body 1 to slowly dry the nuts placed on top of the drying mesh belt 12.

[0032] To improve the drying quality and efficiency of the nuts, the agitator plate 27 can be controlled to rotate downwards and reach a vertical position inside the fixed frame 26. As the extension ends of the multiple first electric telescopic rods 21 retract together, the agitator plate 27 moves downwards to a position abutting against the top of the drying mesh belt 12. As the two first sliders 19 move back and forth within their corresponding first sliding grooves 8, the feed hopper 2 and the agitator plate 27 move back and forth together for adjustment, allowing the agitator plate 27 to move laterally back and forth, automatically agitating the nuts at the top of the drying mesh belt 12. The two second sliders 25 move back and forth inside the corresponding second slide grooves 24, causing the position of the agitator 27 to be adjusted longitudinally. This allows the agitator 27 to more comprehensively move the nuts on the top of the drying mesh belt 12, dispersing the nuts piled up in the middle of the top of the drying mesh belt 12 to both sides. This solves the problems of uneven distribution and accumulation of nuts during the drying process on the top of the drying mesh belt 12, and also gently breaks up damp, clumped nuts, thereby improving the drying efficiency of the nuts on the top of the drying mesh belt 12.

[0033] After the agitator plate 27 agitates the nuts on the top of the drying mesh belt 12, it can be controlled to rotate upwards to reset, and the smoothing plate 28 can be controlled to rotate downwards from the inside of the fixed frame 26 to a vertical state. This allows the smoothing plate 28 to repeat the working steps of the agitator plate 27. With the help of the brush 29 set at the end away from the rotating part, the nuts on the top of the drying mesh belt 12 are spread out, and the thickness of the nuts spread evenly on the top of the drying mesh belt 12 is controlled, so that the overall thickness of the nut layer on the top of the drying mesh belt 12 is uniform, which further improves the subsequent drying efficiency of the nuts.

[0034] The gaps between the multiple feeding teeth of the agitator plate 27 make it easy for some smaller nuts to get stuck in these gaps during the back-and-forth movement of the agitator plate 27, affecting the subsequent use of the agitator plate 27. When nuts are stuck in the multiple gaps inside the agitator plate 27, the smoothing plate 28 has multiple through slots that are adapted to the feeding teeth. The agitator plate 27 can be rotated and adjusted inside the fixed frame 26. After the agitator plate 27 rotates into the smoothing plate 28, the nuts stuck inside it will be automatically pushed outward by the smoothing plate 28, achieving the effect of automatically removing the nuts stuck inside the agitator plate 27. This ensures that the agitator plate 27 has a good agitation effect on the nuts drying on the top of the drying mesh belt 12 during use.

[0035] Furthermore, since the surface of the nuts to be dried contains moisture, they are prone to clogging as they are discharged downwards from the inside of the feed hopper 2 to the top of the drying mesh belt 12. At this time, the agitator 27, which rotates flexibly inside the fixed frame 26, can be used to stir and disperse the nuts that are clogged at the bottom of the feed hopper 2 during rotation. This facilitates the automatic handling of the clogging problem at the bottom of the feed hopper 2, ensuring that the feed hopper 2 can quickly discharge the nuts downwards to the top of the drying mesh belt 12 for drying, thus avoiding the problem of the nuts clogging inside the feed hopper 2 and affecting the drying efficiency.

[0036] After the nuts are dried at the top of the drying mesh belt 12, the limiting plate 14 can be controlled to rotate away from the drying mesh belt 12. Then, the two corresponding drive shafts 11 are controlled to drive the drying mesh belt 12 to rotate clockwise, so as to convey the dried nuts downward to the top of the conveyor mesh belt 13. Then, the other two drive shafts 11 are controlled to drive the conveyor mesh belt 13 to rotate counterclockwise, so as to convey the dried nuts toward the discharge port 3, thus completing the drying process of the nuts.

[0037] If the nuts are dried at the top of the drying conveyor belt 12, and a malfunction in the related drive motor causes the drying conveyor belt 12 to stop rotating and conveying the nuts downwards, in order to prevent the nuts from remaining inside the device body 1 for a long time and being affected by the high temperature and humidity environment inside the device body 1, causing the nuts to quickly become damp, moldy, hot, rancid, and clump together and deteriorate, they must be removed quickly and urgently. Since the nuts have strong adhesion and are easy to stick to the drying conveyor belt 12 after drying, the external preset fan equipment can be started first, so that the air generated by the output end of the fan equipment is delivered to the inside of the two blower heads 38 through the pipe. With the help of the extension ends of the two third electric telescopic rods 40 extending upwards, the two blower heads 38 will push the corresponding cover plates 36 upwards. This allows the two blower heads 38 to move upwards to abut against the bottom of the drying mesh belt 12. As the two motors 34 drive the corresponding lead screws 35 to rotate, the two moving frames 6 drive the two connecting rods 7 to push the two second baffles 33 to move towards each other and away from each other. The two third sliders 39 move back and forth inside the corresponding third slide grooves 37, causing the two blower heads 38 to move back and forth horizontally and vertically at the bottom of the drying mesh belt 12. This allows the airflow blown upwards from the two blower heads 38 to pass through the drying mesh belt 12 and loosen the nuts that are adhering to the drying mesh belt 12 and embedded in the mesh holes, causing them to detach from the top of the drying mesh belt 12. This breaks the adhesion and clumps between the nuts and between the nuts and the drying mesh belt 12, so that the nuts are no longer stuck to the surface of the drying mesh belt 12.

[0038] Next, by using the downward-rotating, vertically positioned toggle plate 27, the above steps of automatically tossing the nuts back and forth on the top of the drying mesh belt 12 can be repeated to further loosen the dried nuts on the top of the drying mesh belt 12, ensuring that the nuts are not stuck to the drying mesh belt 12. Figure 8 As shown, the controllable actuating plate 27 and the smoothing plate 28 rotate downwards together inside the fixed frame 26 to a vertical position, so that they are spliced ​​together to form a push plate mechanism with no internal gaps. With the retraction of the telescopic ends of multiple first electric telescopic rods 21, the push plate mechanism is moved downwards to a position abutting against the top of the drying mesh belt 12. Then, the limiting plate 14 is controlled to rotate away from the drying mesh belt 12 for adjustment. Then, the rotating plate 10 is controlled to rotate inside the emergency discharge outlet 9 towards the drying mesh belt 12 to an inclined state, and the telescopic ends of the two second electric telescopic rods 30 are controlled to extend, causing the abutment plate 31 to abut against the curved part of the drying mesh belt 12. At this time, the corresponding two motors 34 drive the lead screw 35 to rotate, so that the two moving frames 6 drive the two connecting rods 7 and the two first baffles 32 to move towards each other, so that the two first baffles 32 can press the top of the drying mesh belt 12. The nuts are pushed towards the center position. After the nuts are piled up between the two first baffles 32, they can be moved towards the emergency discharge port 9 by the two first sliders 19 in the corresponding first slide grooves 8. This drives the assembled push plate mechanism to push the nuts on top of the drying mesh belt 12, so that the nuts at the top of the drying mesh belt 12 can be discharged from the emergency discharge port 9 to the preset collection container for temporary storage. As the two first sliders 19 drive the push plate mechanism to repeat the above steps multiple times, and the two second sliders 25 move and adjust in the corresponding second slide grooves 24, the push plate mechanism is adjusted longitudinally until all the nuts at the top of the drying mesh belt 12 are discharged from the emergency discharge port 9. This achieves the effect of quickly discharging the dried nuts in the event that the drying mesh belt 12 cannot rotate, avoiding the problem of nuts remaining inside the device body 1 for a long time and affecting the quality of the nuts.

[0039] After the drying of nuts is completed by the device body 1, in order to facilitate the cleaning of residual nut fragments and other impurities inside the device body 1 by the staff using relevant cleaning equipment, the rotating plate 10 can be controlled to rotate inside the emergency discharge port 9 towards the drying mesh belt 12. With the extension of the extension ends of the two second electric telescopic rods 30, the cleaning brush set on the abutment plate 31 is driven to abut against the outer wall of the drying mesh belt 12. Then, the connecting plates 18 magnetically attached to both sides of the feed hopper 2 are manually removed and pushed away from the top of the device body 1. This causes the two shielding curtains 5 at the top ends of the device body 1 to retract, exposing the moving slot 16, which facilitates the rapid dissipation of residual heat inside the device body 1. The drying mesh belt 12 is controlled to continue rotating inside the device body 1, so that it rubs against the cleaning brush, so that the cleaning brush can clean the impurities accumulated in the mesh of the drying mesh belt 12. With the help of the staff, the impurities are automatically removed by the relevant vacuuming equipment, so as to achieve a rapid cleaning effect inside the device body 1.

Step 3: During the drying process of the nuts on the top of the drying mesh belt (12), the control plate (27) rotates downward in the fixed frame (26) to a vertical position. As multiple first electric telescopic rods (21) drive the plate (27) to move downward until it abuts against the top of the drying mesh belt (12), the two first sliders (19) move back and forth in the corresponding first slide groove (8), driving the feed hopper (2) and the plate (27) to move back and forth together, so that the plate (27) moves horizontally back and forth, automatically moving the nuts on the top of the drying mesh belt (12). In conjunction with the two second sliders (25) moving back and forth in the corresponding second slide groove (24), the position of the plate (27) is moved vertically to adjust the position, so that the plate (27) can move the nuts on the top of the drying mesh belt (12) comprehensively. Step 4: After the agitator (27) moves the nuts on the top of the drying mesh belt (12), control the agitator (27) to rotate upward and reset, and control the smoothing plate (28) to rotate downward from the inside of the fixed frame (26) to a vertical state, so that the smoothing plate (28) repeats the working steps of the agitator (27) in Step 3 above. With the help of the brush (29) set at the end away from the rotating part, the nuts on the top of the drying mesh belt (12) are spread out, and the thickness of the nuts on the top of the drying mesh belt (12) is controlled to be uniform, so that the overall thickness of the nut layer on the top of the drying mesh belt (12) is uniform.
