Description

Technical Field

[0001] The utility model relates to the technical field of pecan processing, in particular to a drying device for pecan processing. Background Technique

[0002] The pecan nut shell is thin and easy to peel, the kernel is thick, rich in fat, and tastes sweet. It is a raw material for dried fruits and oil extraction. Although walnuts have long been loved by people as dried fruits, due to their hard shells that are not easy to peel off, their main utilization ways are as oil and food raw materials. The thin-shelled pecan has a shell that is easy to peel off, just like peeling peanuts, and its nutritional value is also much higher than that of ordinary walnuts. The processing process of pecans generally can be divided into: raw material processing (sorting, washing, drying, grading, etc.), shelling, drying, peeling, grading, packaging and other processes.

[0003] For example, the patent document with the publication number CN221489023U discloses a drying device for pecan processing, which includes a box body. There is a feed inlet at the top of the box body. A placement frame is slidably installed in the box body. A drying device is arranged in the box body, and a material stirring mechanism is also arranged in the box body. The drying device is two heating tubes symmetrically distributed and fixed on the inner wall of the box body. A protection structure for protecting the two heating tubes is arranged in the box body. In the prior art, the pecan drying device dries incompletely, resulting in uneven drying on the surface of the pecans and affecting the quality of the pecans. Content of the Utility Model

A microwave generator 3 is fixedly connected to the bottom of the device housing. The device housing is provided with a rotating mechanism. The rotating mechanism includes a support rod 401 fixedly connected to the bottom of the device housing. The upper part of the support rod 401 is rotatably connected to a rear support frame 402. A fixed end plate 403 is fixedly connected to the rear end of the rear support frame 402. A motor 404 is fixedly connected to the rear side of the fixed end plate 403. The output end of the motor 404 is fixedly connected to a driving gear 405. The driving gear 405 is rotatably connected to the fixed end plate 403. A stirring shaft 408 is fixedly connected to the front side of the driving gear 405. A transmission gear 406 is fixedly connected to the front side of the fixed end plate 403. The transmission gear 406 meshes with the driving gear 405. A rotating support 407 is rotatably connected to the front side of the fixed end plate 403. A toothed ring is provided on one side of the rotating support 407. The transmission gear 406 meshes with the toothed ring on the rotating support 407. The rotating support 407 is rotatably connected to the rear support frame 402. An opening is provided at the upper end of the rear support frame 402. A drying cylinder 409 is fixedly connected to the front end of the rotating support 407. A front support frame 410 is rotatably connected to the front side of the drying cylinder 409. An electric telescopic rod 411 is rotatably connected to the lower end of the front support frame 410. The lower end of the electric telescopic rod 411 is hinged to the device housing. A number of air-permeable round holes are provided on the drying cylinder 409. A number of stirring blades are fixedly connected to the stirring shaft 408. A number of through holes are provided on the stirring blades. The washed pecans enter the rotating mechanism through the opening on the rear support frame 402. The rotation of the motor 404 drives the rotation of the driving gear 405. The rotation of the driving gear 405 drives the rotation of the stirring shaft 408. The rotation of the driving gear 405 drives the rotation of the transmission gear 406. The rotation of the transmission gear 406 drives the rotation of the rotating support 407. The rotation of the rotating support 407 drives the rotation of the drying cylinder 409. In this way, the pecans can move continuously in the rotating mechanism. The electric telescopic rod 411 expands and contracts to drive the up and down movement of the front support frame 410. The front end of the rotating mechanism is higher than the rear end, which can prevent the pecans from falling out. The front end of the rotating mechanism is lower than the rear end, which can pour the dried pecans out of the drying device.

[0026] The device housing includes a housing 101 fixedly connected to a support rod 401. At the upper end of the housing 101, a feed hopper 102 is fixedly connected. At the front end of the housing 101, a discharge hopper 103 is fixedly connected. At the upper end of the discharge hopper 103, a gate plate 104 is provided. The gate plate 104 is slidably connected to the housing 101. At the upper end of the housing 101, a cylinder 105 is fixedly connected. The output end of the cylinder 105 is fixedly connected to the gate plate 104. At the rear end of the housing 101, an exhaust fan 106 is fixedly connected. Inside the housing 101, symmetrically arranged humidity monitors 107 are fixedly connected. The lower end of the feed hopper 102 is connected to the upper opening of the rear support frame 402 through a flexible pipe. Observation windows are symmetrically arranged on both sides of the housing 101. The cleaned pecan nuts enter the drying device from the feed hopper 102. The cylinder 105 is activated to push the gate plate 104 downward, making the gate plate 104 fit with the discharge hopper 103. After drying is completed, the gate plate 104 is opened, and the pecan nuts leave the drying device from the discharge hopper 103. The exhaust fan 106 can discharge the internal hot air out of the drying device after drying is completed to accelerate the cooling of the pecan nuts. The humidity monitor 107 can detect the internal humidity to determine the drying degree of the pecan nuts.

[0027] The nitrogen aeration mechanism includes an inlet nitrogen pipe 201 fixedly connected to the upper end of the housing 101. The lower end of the inlet nitrogen pipe 201 is fixedly connected to a gas delivery plate 202. The lower end of the gas delivery plate 202 is fixedly connected to a spray head 203. The inlet nitrogen pipe 201 is externally connected to a nitrogen storage tank. Nitrogen enters the gas delivery plate 202 from the inlet nitrogen pipe 201 and then enters the interior of the drying device from the spray head 203. Nitrogen can reduce the oxygen inside the drying device, reduce the occurrence of oxidation reactions, and adjust the internal humidity.

[0028] Working principle: The cleaned pecan nuts enter the drying device from the feed hopper 102. The washed pecan nuts enter the rotating mechanism from the opening on the rear support frame 402. The motor 404 rotates to drive the driving gear 405 to rotate. The driving gear 405 rotates to drive the stirring shaft 408 to rotate. The driving gear 405 rotates to drive the transmission gear 406 to rotate. The transmission gear 406 rotates to drive the rotating bracket 407 to rotate. The rotating bracket 407 rotates to drive the drying cylinder 409 to rotate. In this way, the pecan nuts can continuously move inside the rotating mechanism. The electric telescopic rod 411 expands and contracts to drive the front support frame 410 to move up and down. The front end of the rotating mechanism is higher than the rear end, which can prevent the pecan nuts from falling out. The microwave generator 3 is activated to dry the pecan nuts using microwaves. During the drying process, nitrogen enters the gas delivery plate 202 from the inlet nitrogen pipe 201 and then enters the interior of the drying device from the spray head 203. After drying is completed, the electric telescopic rod 411 moves to make the front end of the rotating mechanism lower than the rear end, so that the pecan nuts leave the drying device through the discharge hopper 103.
