[0002] Nut processing refers to the use of manual or mechanical methods to remove the shell of the fruit to produce kernels. The process of processing nuts into kernels can generally be divided into: raw material processing (picking, washing, drying, grading, etc.), shelling, drying, peeling, grading, packaging and other processes.

[0003] The drying of nuts is one of the key links in the processing process. Traditional natural drying relies on sun drying. Although it can better preserve the natural flavor and nutrients of nuts, it has many shortcomings: first, the drying efficiency is low, it is completely dependent on natural conditions, and is greatly affected by seasonal and weather changes; second, the nuts are piled or stacked, and the nuts on the lower layer are prone to moisture and mold due to lack of good ventilation, resulting in quality degradation or even scrapping; third, the drying is uneven, the nuts are of different sizes, and the fixed layer spacing is difficult to meet the optimal drying requirements of different nuts. In addition, nuts are prone to rolling and collision during natural stacking, increasing the breakage rate. In response to the above problems, although some drying equipment has appeared on the market, most of them use electric heating or mechanical drying methods, which have high energy consumption and may destroy the natural flavor of nuts. Therefore, it is particularly necessary to develop a device that not only maintains the advantages of natural drying but also overcomes the limitations of existing natural drying.

[0018] See also Figure 1-4The utility model provides a technical solution: a nut drying device, including a side bracket 1, two side brackets 1 are symmetrically provided, and a plurality of drying racks 2 distributed up and down are arranged between the side brackets 1. The drying rack 2 is a rectangular frame structure, and a partition 6 is arranged inside the drying rack 2. The edges of the partition 6 and the inner wall of the drying rack 2 are connected by welding. The space formed between the partition 6 and the bottom inner wall of the drying rack 2 is provided with a laterally distributed blowing pipe 7, and a plurality of nozzles are evenly arranged on the top of the blowing pipe 7. A fan 3 is fixedly installed on one side of the outside of the side bracket 1 through a supporting plate, and the air outlet end of the fan 3 is connected to a main air duct 4, and a plurality of interconnected branch hoses 5 are connected to the main air duct 4. The outer ends of the branch hoses 5 all penetrate into the interior of the bottom end of the drying rack 2 and It is fixedly connected to the middle of the blowing pipe 7 through an interface, and positioning rods 9 penetrating the side bracket 1 are welded and fixed on both sides of the bottom of the drying rack 2. The drying rack 2 with this structure can evenly place the nuts that need to be dried on the partition 6 inside it. When the fan 3 is started, the wind will be transported from the main air duct 4 to each branch hose 5 and flow into the blowing pipe 7. The blowing pipe 7 can spray and dry the nuts placed on the partition 6 inside the drying rack 2 through a plurality of nozzles on the top. In this way, the drying rack 2 can use an air-drying method while naturally drying the nuts, ensuring that the heat and humidity are evenly distributed between the layers of nuts during the drying process. Each drying rack 2 can also be flexibly adjusted between the two side brackets 1 through the positioning rods 9. In order to change the spacing width between each layer, it is beneficial to increase the space for air circulation, so that the nuts in the bottom drying rack 2 can also get good ventilation, reduce the risk of moisture, and thus effectively improve the efficiency and uniformity of drying nuts. A vertical through hole 10 that matches the positioning rod 9 structure is provided on the side bracket 1, and the bottom of the positioning rod 9 is rotatably connected to a locking shaft 11 with a bending structure through a bearing, and a plurality of fitting grooves that match the bottom end structure of the locking shaft 11 are evenly provided on the inner wall of one side of the vertical through hole 10. The positioning rod 9 of the same group of this structure can adjust the height position of the drying rack 2 by sliding to different positions in the vertical through hole 10, and when the drying rack 2 is adjusted to a suitable position between the two side brackets 1, the locking shaft 11 can be adjusted by sliding in the fixed The bottom of the positioning rod 9 rotates to fit the bottom end portion into the corresponding fitting groove on the inner wall of one side of the vertical through hole 10, so as to realize the function of quickly limiting the height of the drying rack 2, which is more convenient to operate. A push rod 12 that slides through the bottom plate of the drying rack 2 is welded and fixed in the middle of the bottom of the blowing pipe 7, and an adjusting screw 13 is provided on the outer side of the connection between the drying rack 2 and the push rod 12. The top of the adjusting screw 13 is connected to the outer wall of the bottom end of the drying rack 2 through a bearing, and the bottom end of the push rod 12 is sleeved on the outside of the adjusting screw 13 through a threaded sleeve. When the adjusting screw 13 of this structure rotates, the push rod 12 can be driven to move up and down through the threaded sleeve. When the push rod 12 moves up and down, the height position of the blowing pipe 7 can be adjusted and controlled, so as to adjust the blowing pipe 7 to a suitable blowing angle.In this way, the blowing pipe 7 can make the wind force more effectively blow and dry the nuts placed on the partition 6, further improving the drying effect to ensure the natural flavor and nutritional value of the nuts. The two sides of the bottom wall of the drying rack 2 are welded and fixed with a bracket 8 of a U-shaped structure, and the inside of the bracket 8 is connected with a bracket block 14 through an elastic pad. The elastic pad here can be made of a high-elasticity sponge material. The top of the bracket block 14 is provided with an arc-shaped recess, and both ends of the blowing pipe 7 are mounted in the arc-shaped recess at the top of the bracket block 14. The drying rack 2 of this structure can adjust the height up and down. When the drying rack 2 is in the correct position, the two ends will squeeze the support block 14 inside the bracket 8. The support block 14 can support the two ends of the drying rack 2 under the elastic force of the elastic pad, which is conducive to improving the stability of the drying rack 2 when adjusting the position. The partition 6 is a hollow structure, and a number of rubber strips are evenly bonded and fixed on the top of the partition 6. The partition 6 of this structure can ensure that the wind force sprayed by the blowing pipe 7 rises evenly, and the several rubber strips on the top of the partition 6 can effectively reduce the rolling amplitude of the nuts when they are blown, greatly reducing the physical damage during the air-drying process.

[0019] Working principle: When using the nut drying device, first place the nuts to be dried evenly inside the drying rack 2 and on the partition 6, then start the fan 3. When the fan 3 is started, the wind will be transported from the main air duct 4 to each branch hose 5. The wind in the branch hose 5 will then flow into each spray pipe 7. The spray pipe 7 can spray and dry the nuts placed on the partition 6 through a number of nozzles on the top. When it is necessary to better dry the nuts in the drying rack 2 on the bottom layer, each drying rack 2 can slide to different positions in the vertical opening 10 through two positioning rods 9 to change the spacing width between each layer. When the drying rack 2 is adjusted to a suitable position between the two side brackets 1, the locking shaft 11 can rotate at the bottom of the positioning rod 9 to fit the bottom end portion into the inner wall on one side of the vertical opening 10. The corresponding interlocking groove can be used to quickly limit the position of the drying rack 2 after adjustment, which is conducive to increasing the space for air circulation, so that the nuts in the bottom drying rack 2 can also get good ventilation, and the operator can also rotate the adjusting screw 13. When the adjusting screw 13 rotates, the push rod 12 can be driven up and down by the screw sleeve. When the push rod 12 moves up and down, the height position of the blowing pipe 7 can be adjusted and controlled. When the height position of the drying rack 2 is adjusted up and down, the two ends will squeeze the support block 14 inside the bracket 8. The support block 14 can support the two ends of the drying rack 2 under the elastic force of the elastic pad until the blowing pipe 7 is adjusted to a suitable blowing angle, so that the blowing pipe 7 can make the wind force more effectively blow and dry the nuts placed on the partition 6, so that the effect of drying the nuts is better, thereby completing a series of tasks.
