Description

Technical Field

[0001] The present application relates to the field of peanut processing, and in particular to a peanut semi-microwave drying device. Background Art

[0002] Currently, in the processing of peanut products, pretreatment is a key step. First, peanuts need to be washed to remove impurities, and then peanut kernels are obtained through mechanical shelling. Since the moisture content of the shelled peanut kernels is relatively high and they are prone to mildew, drying treatment is required. Generally, hot air drying or microwave drying technology is used to reduce the moisture content to 8%-10% to ensure the quality and shelf life of peanuts.

[0003] The related technology can refer to the Chinese patent application with the publication number CN221864536U, which discloses a peanut cleaning and drying integrated machine in the field of peanut processing. The peanut cleaning and drying integrated machine includes a cleaning box and a drying box. An air inlet hood is installed at the top of the drying box, and a driving motor and an electric heating wire are respectively installed inside the air inlet hood. The output end of the driving motor is connected to a driving shaft. By setting a material turning component, when the washed peanuts enter the drying box, the peanuts will fall onto the guide net. At this time, when the driving shaft rotates, it will drive the driving bevel gear to rotate, the driving bevel gear will drive the driven bevel gear to rotate, the driven bevel gear will drive the movable shaft to rotate, the movable shaft will drive the driving pulley to rotate, and then drive the driven pulley to rotate through a belt and drive the rotating shaft to rotate. The rotating shaft will drive the turning plate to rotate. After the turning plate rotates, it can lift the peanuts on the guide net, making the peanuts roll down level by level. The rolling peanuts can fully contact the hot air, thereby improving the drying efficiency of peanuts.

[0004] In view of the above related technology, during the process of the rotating shaft driving the turning plate to rotate, the peanuts move sequentially on the guide net. During the movement, the probability of peanut accumulation can be reduced. However, during the drying process, the drying effect of the peanuts close to the air nozzle is better than that of the peanuts far from the air nozzle. The rotating shaft drives the turning plate to move, making the peanuts move sequentially on adjacent guide nets. During the movement, the interval between the peanuts can be increased, but the peanuts far from the air nozzle cannot be transported to the position close to the air nozzle, resulting in poor drying uniformity of the peanuts during the drying process. Summary of the Invention

[0005] In order to improve the drying uniformity of peanuts, the present application provides a peanut semi-microwave drying device.

[0006] The present application provides a peanut semi-microwave drying device, adopting the following technical solutions: A peanut semi-microwave drying device, comprising a box body, a microwave heater and a stirring device. The microwave heater and the stirring device are both located inside the box body. The microwave heater is located at the upper end of the box body. A connecting cylinder is fixedly arranged inside the box body, and the connecting cylinder is located at the upper end of the box body. An exhaust port is vertically opened at the upper end of the box body. A feed pipe is communicated with the upper end of the box body. The stirring device includes a rotating motor, a first gear, a second gear, a first rotating shaft, a plurality of second rotating shafts and a connecting piece. The rotating motor is fixedly connected to the upper end of the box body and is horizontally arranged. The upper ends of the first rotating shaft and the plurality of second rotating shafts pass through the box body and are rotatably connected to the box body. The plurality of second rotating shafts are uniformly arranged circumferentially along the first rotating shaft. The second gear is sleeved outside the first rotating shaft and rotates coaxially. The first gear is fixedly connected to the output shaft of the rotating motor and meshes with the second gear. The connecting piece is located inside the box body and is used to connect the first rotating shaft and the second rotating shaft. A rotating rod is fixedly arranged at the lower end of the first rotating shaft. A plurality of first guide plates are fixedly arranged axially along the outside of the first rotating shaft. A plurality of second guide plates are fixedly arranged axially along the outside of the second rotating shaft. The rotating rod is inclined from top to bottom in the direction from the center of the box body to the outer edge of the box body. The first guide plates and the second guide plates are inclined from right to left in the direction from the center of the box body to the outer edge of the box body. A support member is arranged at the lower end of the connecting cylinder. A peeling component is arranged inside the box body, and the peeling component is located below the support member and is used to peel the peanut kernels. A separation component is arranged inside the box body, and the separation component is located below the peeling component.

[0007] By adopting the above technical solution, the peanut kernels are added into the box body through the feed pipe. The microwave heater heats and dries the peanut kernels inside the connecting cylinder. The exhaust port is used to keep the air pressure inside and outside the box body consistent. The rotating motor rotates, and the first gear and the second gear cooperate to drive the first rotating shaft to rotate. The connecting piece connects the first rotating shaft and the second rotating shaft, and then the first rotating shaft drives the second rotating shaft to rotate. During the rotation of the first rotating shaft, a plurality of first guide plates rotate to convey the peanut kernels at the center of the box body to the outer edge of the box body. A plurality of second guide plates rotate to make the peanut kernels at the outer edge of the box body move along the circumference of the connecting cylinder. The support member supports the peanut kernels inside the connecting cylinder. The rotating rod is used to convey the peanut kernels at the bottom of the connecting cylinder upward. After the peanut kernels are dried, the peeling component removes the red skins of the peanut kernels. The separation component separates the peanut kernels from the red skins and collects the red skins, improving the drying uniformity of the peanuts.

[0008] Optionally, the connecting piece includes a third gear and a plurality of fourth gears. The third gear is sleeved outside the first rotating shaft and rotates coaxially with the first rotating shaft. The fourth gears correspond to the second rotating shafts one by one. The fourth gear is sleeved outside the second rotating shaft and rotates coaxially. The third gear meshes with the fourth gear.

[0009] By adopting the above technical solution, the first rotating shaft drives the third gear to rotate. The third gear drives the second gear to rotate through the fourth gear, improving the connection stability between the first rotating shaft and the second rotating shaft and the convenience of rotation.

[0010] Optionally, a hot air device is fixedly installed at the upper end of the box body. A scraping plate is fixedly installed at one end of the rotating rod away from the first rotating shaft. The scraping plate is arranged vertically and is in contact with the connecting cylinder. The first rotating shaft, the second rotating shaft, the first guiding plate, the second guiding plate and the rotating rod are all hollow. The first guiding plate and the rotating rod are both communicated with the first rotating shaft, and the second guiding plate is communicated with the second rotating shaft. A number of air-permeable holes are opened in the first guiding plate, the second guiding plate and the rotating rod. A number of air delivery pipes are communicated with one side of the hot air device. The number of air delivery pipes are respectively communicated with the first rotating shaft and the second rotating shaft.

[0011] By adopting the above technical solution, the hot air device conveys hot air into the first rotating shaft and the second rotating shaft through the air delivery pipes. The hot air enters the box body from the first guiding plate and the second guiding plate through the air-permeable holes, which is beneficial to improving the drying efficiency of peanut kernels and reducing the probability that the red skins adhere to the first guiding plate and the second guiding plate during the stirring process of peanut kernels.

[0012] Optionally, the supporting member includes two supporting plates. The upper ends of the two supporting plates are both in contact with the lower end of the connecting cylinder. The two sides of the two supporting plates along the length direction are both in contact with the box body. The two sides of the two supporting plates away from each other are hinged to the box body vertically. Two sliding openings are opened on one side of the box body along the length direction of the supporting plate. The sliding openings correspond to the supporting plates one by one. A sliding block is arranged on one side of the supporting plate close to the sliding opening. The sliding block is slidably connected to the supporting plate along the width direction of the supporting plate and is located in the sliding opening. A cover plate is hinged to the upper end of the box body vertically. A sealing ring is fixedly installed on one side of the cover plate close to the exhaust port. The cover plate is opposite to the exhaust port. A driving member is arranged between the cover plate and the sliding block.

[0013] By adopting the above technical solution, during drying, the two supporting plates support the peanut kernels. When the drying is completed, the driving member pushes the sliding block to move in the sliding opening and move along the width direction of the supporting plate, so that the two supporting plates are separated from each other. While the two supporting plates are separated from each other, the driving member drives the cover plate to cover the exhaust port. The cooperation of the sealing ring and the cover plate enables the gas in the box body to be conveyed only downward of the box body, which is beneficial to reducing the probability of peanut kernels accumulating between the two supporting plates and the convenience of separating the two supporting plates.

[0014] Optionally, the driving member includes a double-acting cylinder, two first connecting rods and a second connecting rod. The double-acting cylinder is fixedly connected to the outside of the box body and is located above the supporting plate. The double-acting cylinder is arranged vertically. The first connecting rods correspond to the sliding blocks one by one. The upper end of the first connecting rod is vertically hinged to the output end below the double-acting cylinder, and the lower end of the first connecting rod is vertically hinged to the sliding block. The second connecting rod is fixedly connected to the output end above the double-acting cylinder and is arranged vertically. The upper end of the second connecting rod is vertically hinged to the cover plate and is slidably connected to the cover plate along the length direction of the cover plate.

[0015] By adopting the above technical solution, the output end below the double-acting cylinder extends, and the two first connecting rods push the two sliders to move downward along the box body and move away from the double-acting cylinder. As a result, the two support plates are separated from each other, and a channel for the peanut kernels to fall is formed. The output end above the double-acting cylinder contracts, driving the second connecting rod to descend. During the descent of the second connecting rod, the cover plate is driven to cover the exhaust port, further improving the convenience of separating the two support plates and reducing the probability of peanut kernels accumulating between the two support plates.

[0016] Optionally, the peeling assembly includes a flow dividing block, a plurality of rollers and a driving device. The flow dividing block is fixedly connected to the inner side of the box body and is horizontally arranged along the length direction of the support plate. The flow dividing block is hollow, and flow dividing ports are opened at both the upper end and the lower end of the flow dividing block. A plurality of placement ports are opened along the length direction at the upper end of the flow dividing block. The rollers correspond to the placement ports one by one. The rollers are located in the placement ports and are horizontally arranged along the length direction of the support plate. Both ends of the rollers are connected to the box body and are rotatably connected to the box body in the vertical direction. The driving device is located outside the box body.

[0017] By adopting the above technical solution, the peanut kernels fall from the two support plates and enter the inside of the flow dividing block from the flow dividing ports. The driving device drives the plurality of rollers to rotate. The rollers come into contact with the peanut kernels, thereby separating the peanut kernels from the red skins. Since the exhaust port is in a closed state, the airflow in the connecting cylinder is in the same direction as the moving direction of the peanut kernels. Due to the push of the airflow, it is beneficial to reduce the probability of peanut kernels accumulating in the flow dividing block and improve the efficiency of removing the red skins from the peanut kernels.

[0018] Optionally, the separation assembly includes a rotary motor, a lead screw, a moving block and two sealing plates. First moving ports are opened on both sides of the box body along the length direction. The sealing plates correspond to the first moving ports one by one. The two sealing plates are attached to each other and are located in the first moving ports. The sealing plates are slidably connected to the box body along their own width directions. A second moving port is opened on one side of the box body along the width direction. A moving member is provided in the second moving port for driving the two sealing plates to approach or move away from each other. The rotary motor is fixedly connected to one side of the box body along the length direction and is located above the first moving port. The output shaft of the rotary motor passes through the box body and is fixedly connected to the lead screw. The lead screw passes through the moving block and is threadedly connected to the moving block. Separation blocks are provided on both sides of the moving block along the width direction. Exhaust pipes are communicated with both sides of the box body along the width direction of the support plate. Air extractors are provided in the exhaust pipes. One end of the exhaust pipe far from the box body is communicated with a cloth bag.

[0019] By adopting the above technical solution, the peanut kernels fall onto the upper sides of the two blocking plates after removing the red skins. The rotating motor rotates, and the lead screw drives the moving block to slide along the length direction of the lead screw. The separating blocks on both sides of the moving block are used to convey the peanut red skins below upward, making the red skins in a floating state. The air extractor conveys the peanut red skins in the box to the cloth bag for recycling through the exhaust pipe. When the red skin cleaning is completed, the moving parts in the second moving port drive the two blocking plates to slide in the first moving port, so that the peanut kernels above the blocking plates fall to the lower end of the box, improving the efficiency and convenience of removing the peanut red skins.

[0020] Optionally, receiving grooves are opened on both sides of the moving block in the width direction. The two separating blocks are slidably connected to the moving block along their own width directions. A plurality of springs are arranged in the receiving grooves. One end of each spring is fixedly connected to the moving block, and the other end of each spring is fixedly connected to the separating block. A guiding cylinder is fixedly arranged in the box, and the guiding cylinder is located below the blocking plate. The lower end of the box is communicated with a discharge pipe.

[0021] By adopting the above technical solution, when the separating block contacts the box body, the separating block squeezes the spring and moves into the receiving groove. The peanut kernels after the red skins are removed flow into the discharge pipe through the guiding cylinder for recycling, which is beneficial to reducing the probability of peanut kernel breakage caused by the squeezing of the separating block on the peanut kernels and improving the particle integrity of the peanut kernels.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the rotation of the first rotating shaft, a plurality of first guiding plates rotate to convey the peanut kernels in the center of the box to the outer edge of the box. A plurality of second guiding plates rotate, so that the peanut kernels at the outer edge of the box move along the circumference of the connecting cylinder. The supporting member supports the peanut kernels inside the connecting cylinder, and the rotating rod is used to convey the peanut kernels at the bottom of the connecting cylinder upward, which is beneficial to making the peanut kernels move sufficiently in the box, keeping the heating degree of the peanut kernels in the box uniform, and improving the drying uniformity of the peanut kernels; 2. The peanut kernels fall from the two supporting plates and enter the inside of the shunt block from the shunt port. The driving device drives a plurality of rollers to rotate. The rollers contact the peanut kernels, and then separate the peanut kernels from the red skins. Since the two-way cylinder and the second connecting rod cooperate to keep the exhaust port closed, the air flow in the connecting cylinder is in the same direction as the moving direction of the peanut kernels. Due to the pushing of the air flow, it is beneficial to reduce the probability of peanut kernel accumulation in the shunt block and improve the efficiency of removing the red skins of the peanut kernels; 3. The rotating motor rotates, and the lead screw drives the moving block to slide along the length direction of the lead screw. The separating blocks on both sides of the moving block are used to convey the peanut red skins below upward, making the red skins in a floating state. The air extractor conveys the peanut red skins in the box to the cloth bag for recycling through the exhaust pipe, improving the efficiency and convenience of removing the peanut red skins.

When the separation block 631 contacts the box body 1, the separation block 631 squeezes the spring 633 and moves towards the inside of the receiving groove 632.

[0048] Refer to Figure 1 and Figure 2 , a guide cylinder 17 is fixedly provided in the box body 1. The guide cylinder 17 is located below the blocking plate 64. A discharge pipe 18 is connected to the lower end of the box body 1. The peanut kernels after the red skin removal flow into the discharge pipe 18 through the guide cylinder 17 for recycling, which is beneficial to reducing the probability of peanut kernel breakage caused by the extrusion of the separation block 631 and improving the particle integrity of the peanut kernels.

[0049] The implementation principle of a peanut semi-microwave drying device according to an embodiment of the present application is as follows: During the rotation of the first rotating shaft 24, multiple first guide plates 242 rotate to convey the peanut kernels at the center of the box body 1 to the outer edge of the box body 1. Multiple second guide plates 251 rotate to move the peanut kernels at the outer edge of the box body 1 along the circumferential direction of the connecting cylinder 12. The rotating rod 241 conveys the peanut kernels at the bottom of the connecting cylinder 12 upward, enabling the peanut kernels to move sufficiently within the box body 1, so that the heating degree of the peanut kernels within the box body 1 remains uniform. The hot air device 7 conveys hot air into the first rotating shaft 24 and the second rotating shaft 25 through the air delivery pipe 71. The hot air enters the interior of the box body 1 from the first guide plate 242 and the second guide plate 251 through the air permeation holes 252. The driving member 8 separates the two support plates 41 and simultaneously closes the exhaust port 13 with the cover plate 44. The peanut kernels fall from between the two support plates 41 and enter the interior of the flow dividing block 51 from the flow dividing port 54. The driving device 53 drives multiple rollers 52 to rotate. The rollers 52 come into contact with the peanut kernels, thereby separating the peanut kernels from the red skins. Since the exhaust port 13 is in a closed state, the airflow within the connecting cylinder 12 is in the same direction as the movement of the peanut kernels. Due to the push of the airflow, the peanut kernels smoothly enter the next process. The moving block 63 drives the separating block 631 to move along the length direction of the lead screw 62. The separating block 631 conveys the peanut red skins below upward, causing the red skins to be in a floating state. The air extractor conveys the peanut red skins within the box body 1 to the cloth bag 16 through the exhaust pipe 15 for recovery. The cooperation of the first guide plate 242, the second guide plate 251, and the rotating rod 241 enables the peanut kernels to move sufficiently within the box body 1, so that the heating degree of the peanut kernels within the box body 1 remains uniform, improving the uniformity of peanut kernel drying.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
