Technical Field
[0001] This utility model relates to the field of walnut kernel processing technology, and in particular to a high-temperature dryer for walnut kernel production. Background Technology
[0002] Walnuts are a type of dried fruit and contain moisture. If the storage environment is humid, walnuts can easily absorb moisture from the air, which can lead to mold growth. Drying can effectively reduce the moisture content of walnuts, thereby reducing the risk of moisture absorption and preventing mold and spoilage caused by a humid environment. Drying is especially important in high-humidity areas, such as southern regions.
[0003] The high-temperature dryer used in walnut kernel production is a device specifically designed to dry walnut kernels to ensure that they reach the ideal degree of dryness, making them easy to store and process later.
[0004] Existing high-temperature dryers for walnut kernel production suffer from uneven internal temperature distribution during the drying process. This results in some areas being too hot, which can easily lead to over-roasting or localized scorching of the walnut kernels, while other areas retain high levels of moisture. Therefore, a new high-temperature dryer for walnut kernel production is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high-temperature dryer for walnut kernel production, which aims to improve the problem that existing high-temperature dryers for walnut kernel production have uneven internal temperature distribution when drying walnut kernels, resulting in some areas having higher temperatures, which can easily cause over-roasting or local scorching of the walnut kernels, while other areas have high residual humidity.

[0009] As a further description of the above technical solution: the connecting plate is arranged perpendicularly to the connecting shaft, and the bottom of the connecting plate is arranged perpendicularly to the top surface of the drying plate;
[0010] As a further description of the above technical solution: the placement plate and the drying tank are adapted to each other, and the first vent hole and the second vent hole are the same size;
[0011] As a further description of the above technical solution: the placement plate is movably connected to the inside of the drying tank, and the first vent hole and the second vent hole are vertically overlapped;

Detailed Implementation
[0022] 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.
[0023] Reference Figure 1 - Figure 3This utility model provides an embodiment of a high-temperature dryer for producing walnut kernels, comprising a shell 1, a dryer body 2 fixedly connected to the bottom inner side of the shell 1, an exhaust pipe 3 fixedly connected to the top of the shell 1, a motor frame 4 fixedly connected to one side surface of the shell 1, a drive motor 5 fixedly connected to the surface of the motor frame 4, a door 6 rotatably connected to one side surface of the shell 1, and a drying assembly 7 disposed inside the shell 1. The drying assembly 7 includes a drive shaft 71 rotatably connected between the inner walls of the shell 1, and connecting rods uniformly fixedly connected to the surface of the drive shaft 71. Connecting rod 72, with connecting shaft 73 fixedly connected between the opposite surfaces of the two connecting rods 72. Connecting plates 74 are symmetrically rotatably connected to the surfaces of the connecting shafts 73. Drying plates 75 are fixedly connected to the bottom surfaces of the connecting plates 74. Drying grooves 76 are formed on the surface of each drying plate 75, and first ventilation holes 77 are formed on the bottom surface of each drying plate 75. The walnut kernels to be dried are evenly distributed inside the placement grooves 82 on the surface of the placement plate 81. Then, the placement plate 81 is placed inside the drying grooves 76 on the surface of the drying plate 75, and the fixing plate 84 is snapped in place. Inside the slot 85, the door 6 is then closed, and the drive motor 5 and the dryer body 2 are started. Hot air flows through the first vent 77 and the second vent 83 to dry the walnut kernels inside the placement slot 82. During this process, the drive motor 5 drives the drive shaft 71 to rotate, and the drive shaft 71 drives the connecting rod 72 and the connecting shaft 73 to perform circular motion. Because the connecting plate 74 is rotatably connected to the surface of the connecting shaft 73, under the gravity of the drying plate 75 and the placement plate 81, the drying plate 75 and the placement plate 81 always remain in a vertical state. While the drying plate 75 and the placement plate 81 move in a circular motion, each drying plate 75 and placement plate 81 can pass evenly over the dryer body 2, so that the walnut kernels inside the placement trough 82 can be dried evenly. The surface of the drying plate 75 is provided with a placement component 8. The output shaft of the drive motor 5 is fixedly connected to one end of the drive shaft 71. The connecting plate 74 is rotatably connected to both sides of the surface of the connecting shaft 73. The connecting plate 74 is perpendicular to the connecting shaft 73, and the bottom of the connecting plate 74 is perpendicular to the top surface of the drying plate 75.
[0024] Reference Figure 1 - Figure 3 The placement assembly 8 includes a placement plate 81 placed inside the drying plate 75. The surface of the placement plate 81 is provided with a placement groove 82. The bottom surface of the placement plate 81 is provided with second ventilation holes 83 evenly distributed. Both ends of the placement plate 81 are fixedly connected to fixing plates 84. Both ends of the drying plate 75 are provided with slots 85. The placement plate 81 and the drying trough 76 are adapted to each other. The first ventilation hole 77 and the second ventilation hole 83 are the same size. The placement plate 81 is movably connected inside the drying trough 76. The first ventilation hole 77 and the second ventilation hole 83 are vertically overlapped. The fixing plates 84 are all snapped into the slots 85. The placement groove 82 is used to lay the walnut kernels to be dried flat.
[0025] Working principle: During use, the walnut kernels to be dried are evenly distributed inside the placement groove 82 on the surface of the placement plate 81. Then, the placement plate 81 is placed inside the drying groove 76 on the surface of the drying plate 75. The fixing plate 84 is then engaged inside the slot 85. The door 6 is then closed, and the drive motor 5 and the dryer body 2 are started. Hot air flows through the first vent 77 and the second vent 83 to dry the walnut kernels inside the placement groove 82. During this process, the drive motor 5 drives the drive shaft 71 to rotate, and the drive shaft 71 drives the connecting rod 72 and the connecting shaft 73 to perform circular motion. The connecting plate 74 is rotatably connected to the surface of the connecting shaft 73. Under the gravity of the drying plate 75 and the placement plate 81, the drying plate 75 and the placement plate 81 always remain vertical. While the drying plate 75 and the placement plate 81 are moving in a circular motion, each drying plate 75 and the placement plate 81 can pass evenly over the dryer body 2, so that the walnut kernels inside the placement trough 82 can get a uniform drying effect. This avoids uneven temperature distribution inside the shell 1, which can lead to excessively high temperature in some areas, causing the walnut kernels to be over-roasted or locally scorched, while other areas have high residual humidity.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
