Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a drying device for dried venison. Background Technology

[0002] In the processing of venison jerky, traditional air-drying methods mainly rely on natural sun-drying or simple air-drying equipment. Natural sun-drying is greatly affected by weather and environmental factors. For example, rainy weather can easily cause venison jerky to mold and spoil. Moreover, being exposed to an open environment, dust, insects and other impurities can easily adhere to it, making it difficult to guarantee food hygiene and safety.

[0003] Existing simple air-drying equipment is mostly a fixed structure, with the bottom drying layer located at a low position. Operators need to frequently bend over to place or remove the dried venison from the bottom layer. This repetitive bending motion can easily lead to lower back fatigue and injury, increasing occupational health risks. At the same time, its air intake system lacks an effective filtration device, and the air comes into direct contact with the dried venison without purification, posing a risk of microbial contamination. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an air-drying device for dried venison.

[0005] The air-drying device for dried venison provided by this utility model includes: an air-drying box, an air inlet pipe, a filter structure, a side plate, a lifting structure, a bottom plate, and a top plate. The top of the air-drying box has an inlet / outlet slot. A support column is fixedly connected to the lower surface of the air-drying box. Three through holes are opened at the bottom of the air-drying box, and an air inlet pipe is fixedly connected to the outer side of each of the three through holes. A filter structure is provided at the end of the air inlet pipe away from the air-drying box. The filter structure includes a sealing cover, an air guide pipe, and a filter element. The sealing cover is threaded to the outer surface of the end of the air inlet pipe away from the air-drying box. A fixing hole is opened on the side surface of the sealing cover, and a guide pipe is fixedly connected inside the fixing hole on the side surface of the sealing cover. The air duct extends into the air inlet duct at one end, and a filter element is fitted on the outer surface of the end of the air duct that extends into the air inlet duct. The drying box has two side plates inside, and each side plate has a lifting structure on the side away from each other. The lifting structure includes a guide rail, a lifting block, a lead screw, and a servo motor. The lifting block is slidably connected inside the guide rail. One side of the lifting block passes through the guide rail and is fixedly connected to the outer surface of the side plate. The upper surface of the lifting block has a threaded hole, and a lead screw is threaded inside the threaded hole. A servo motor is installed at the lower end of the lead screw. Four bottom plates are fixedly connected between the two side plates, and a top plate is fixedly connected to the upper part of the two side plates.

[0006] Preferably, the air duct has a dispersion hole on the outer surface of one end of the air inlet pipe, and the other end of the air duct extends to the outer surface of the sealing cover. An air intake fan is fixedly connected to one end of the air duct on the outer surface of the sealing cover.

[0007] Preferably, the outer surface of the guide rail is fixedly connected to the inner wall of the drying box, and a partition is fixedly connected to the inner wall of the lower end of the guide rail, with a through hole on the upper surface of the partition.

[0008] Preferably, the lead screw is rotatably connected to the inside of the through hole on the upper surface of the partition plate, the upper end of the lead screw is rotatably connected to the top of the guide rail, the lower end of the lead screw is fixedly connected to the power output end of the servo motor, and the outer surface of the servo motor is fixedly connected to the inner wall of the guide rail.

[0009] Preferably, each of the four base plates has ventilation holes on its upper surface, and a carrier box is placed on the upper surface of each of the four base plates. The bottom of the carrier box also has ventilation holes.

[0010] Preferably, the top plate has three through holes on its upper surface, and an exhaust fan is fixedly connected to the outside of each of the three through holes on the upper surface of the top plate.

[0011] Compared with related technologies, the air-drying device for dried venison provided by this utility model has the following beneficial effects:

[0012] 1. By incorporating a lifting structure and activating a servo motor, the servo motor's power output in the lifting structure rotates simultaneously on one side of the two side plates, moving them away from each other. The rotation of the servo motor's power output drives the lead screw to rotate synchronously in the same direction. The lead screw connects with the threaded hole on the upper surface of the lifting block, causing the lifting block to rise along the guide rail. The lifting block then lifts the side plates, bottom plate, carrier box, and top plate as a whole. During the ascent, the bottom plate pauses sequentially. When removing venison, it starts from the top bottom plate and descends sequentially. When placing venison, the servo motor's power output reverses, causing the lifting block to lower the side plates, bottom plate, carrier box, and top plate as a whole. During the descent, the bottom plate pauses sequentially, and venison is placed from the bottom bottom plate upwards sequentially. This allows for the loading and unloading of venison jerky without bending over, reducing the risk of lower back strain and improving the working environment.

[0013] 2. Equipped with an intake fan, air inlet duct, filter structure, and exhaust fan, the system draws in outside air when the intake fan is activated. The air passes through the air duct and filter element, which intercepts dust and impurities, ensuring clean air enters the drying chamber through the air inlet duct. The clean air flows upward from the bottom opening of the drying chamber, passing through the bottom plate vent, the carrier box vent, and the dried venison in sequence. The airflow fully contacts the dried venison, carrying away surface moisture, forming a flow of hot and humid air towards the top plate of the drying chamber. The exhaust fan is then activated to force the hot and humid air out, creating a "bottom in, top out" airflow path. This maintains the air pressure balance inside the drying chamber, accelerates moisture evaporation, ensures the cleanliness of the air entering the drying chamber, and prevents the dried venison from becoming contaminated during the drying process.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The system includes: a drying box 1, an air inlet duct 2, a filter structure 3, a side panel 4, a lifting structure 5, a bottom plate 6, and a top plate 7. The top of the drying box 1 has an inlet / outlet slot. A support column 19 is fixedly connected to the lower surface of the drying box 1, maintaining a certain distance between the drying box 1 and the ground to facilitate the installation of the air inlet duct 2 and air circulation. The bottom of the drying box 1 has three through holes, each with an air inlet duct 2 fixedly connected to its outer side. The air inlet duct 2 introduces external air into the drying box 1, directing it to the bottom and guiding the airflow upwards. A filter structure 3 is installed at the end of the air inlet duct 2 furthest from the drying box 1. The filter structure 3 includes a sealing cover 8, an air duct 9, and a filter element 10. The sealing cover 8 is threaded to the outer surface of the end of the air inlet pipe 2 away from the drying box 1. A fixing hole is provided on the side surface of the sealing cover 8, and the air duct 9 is fixedly connected inside the fixing hole. One end of the air duct 9 extends into the interior of the air inlet pipe 2. The sealing cover 8 is fitted with the air duct 9 to ensure a tight seal between the air duct 9 and the air inlet pipe 2. The filter element 10 is fitted onto the outer surface of the end of the air duct 9 that extends into the air inlet pipe 2. The sealing cover 8 is threaded to one end of the air inlet pipe 2, which facilitates disassembly and maintenance, and makes it easy to replace the filter element 10. Core 10 filters dust and impurities from the air to prevent contamination of the dried venison and ensure a clean drying environment. The drying chamber 1 contains two side plates 4, each with a lifting structure 5 on the side furthest from each other. The lifting structure 5 includes a guide rail 11, a lifting block 12, a lead screw 13, and a servo motor 14. The lifting block 12 is slidably connected inside the guide rail 11. One side of the lifting block 12 passes through the guide rail 11 and is fixedly connected to the outer surface of the side plate 4. When the lifting block 12 moves up and down along the guide rail 11, it can drive the side plate 4 to move up and down. A threaded hole is provided on the upper surface of the lifting block 12, and the threaded hole on the upper surface of the lifting block 12 is threaded... A lead screw 13 is connected to the dryer, and a servo motor 14 is installed at the lower end of the lead screw 13. Four bottom plates 6 are fixedly connected between the two side plates 4. A top plate 7 is fixedly connected to the upper end of the two side plates 4. The top plate 7 is used to seal the inlet and outlet slot of the drying box 1. When the lifting block 12 drives the side plates 4 to rise, the top plate 7 is disengaged from the drying box 1. At this time, the side plates 4 drive the bottom plates 6 through the inlet and outlet slot on the upper surface of the drying box 1 and into the outer surface of the drying box 1, which facilitates the removal of dried venison and the placement of venison to be dried. When removing venison, it is taken out sequentially starting from the bottom plate 6 located at the upper end of the side plates 4, while when placing venison, it is placed sequentially starting from the bottom plate 6 at the lower end of the side plates 4.

[0022] In the specific implementation process, the air guide duct 9 has a dispersion hole on the outer surface of one end of the air inlet duct 2, and the other end of the air guide duct 9 extends to the outer surface of the sealing cover 8. An air intake fan 15 is fixedly connected to one end of the air guide duct 9 on the outer surface of the sealing cover 8. The air intake fan 15 is used to actively draw in external air and accelerate the air intake process. The air intake fan 15 draws air into the air guide duct 9, and the air guide duct 9 evenly disperses the drawn air into the air inlet duct 2 through the dispersion hole to avoid airflow concentration.

[0023] The outer surface of the guide rail 11 is fixedly connected to the inner wall of the drying box 1, and a partition 16 is fixedly connected to the lower inner wall of the guide rail 11. A through hole is opened on the upper surface of the partition 16, which facilitates the installation of the lead screw 13.

[0024] The lead screw 13 is rotatably connected to the through hole on the upper surface of the partition 16, allowing it to rotate within the hole. The upper end of the lead screw 13 is rotatably connected to the top of the guide rail 11, and the lower end is fixedly connected to the power output end of the servo motor 14. The outer surface of the servo motor 14 is fixedly connected to the inner wall of the guide rail 11. The servo motor 14 is electrically connected to an external power supply and a PLC controller. The PLC controller is a Siemens S7-1200 series; however, specific models can be replaced according to actual needs. The PLC controller is a commonly used technology and will not be elaborated upon here. The operator controls and starts the servo motor 14 through the external PLC controller, causing the power output ends of the servo motor 14 in the lifting structure 5 to rotate simultaneously on one side of the two side plates 4. When the power output end of the servo motor 14 rotates, it drives the lead screw 13 to rotate synchronously in the same direction. When the lead screw 13 rotates, it is threadedly connected to the threaded hole on the upper surface of the lifting block 12, causing the lifting block 12 to rise and fall along the guide rail 11.

[0025] The four base plates 6 are provided with ventilation holes on their upper surfaces. The base plates 6 are used to place the carrier box 17. The ventilation holes on the upper surface of the base plates 6, together with the ventilation holes at the bottom of the carrier box 17, allow the airflow to pass through the dried venison evenly. The carrier box 17 is placed on the upper surface of each of the four base plates 6. The carrier box 17 is also provided with ventilation holes at its bottom. The carrier box 17 is used to hold the dried venison to be dried. The ventilation holes at the bottom of the carrier box 17, together with the ventilation holes on the base plates 6, allow the airflow to pass through the dried venison and achieve uniform drying.

[0026] The top plate 7 has three through holes on its upper surface. Each of the three through holes on the upper surface of the top plate 7 is fixedly connected to an exhaust fan 18. The exhaust fan 18 is electrically connected to an external power source. When the exhaust fan 18 is started, it actively discharges the hot and humid air in the drying box 1, accelerates air circulation, and improves drying efficiency. Combined with the air intake of the air inlet pipe 2, it forms a "bottom in, top out" airflow path, which optimizes the drying effect.

[0027] The working principle of this utility model is as follows: The operator starts the intake fan 15, which actively draws in external air. The air passes through the air duct 9 and the filter element 10, which intercepts dust and impurities, ensuring that clean air enters the drying chamber 1 through the air inlet duct 2. The clean air flows upward from the bottom hole of the drying chamber 1, passing through the ventilation holes of the bottom plate 6, the ventilation holes of the carrier box 17, and the dried venison in sequence. The airflow fully contacts the dried venison, carrying away surface moisture, forming a flow of hot and humid air towards the top plate 7 of the drying chamber 1. The exhaust fan 18 is then started to force the hot and humid air out, forming a "bottom in, top out" airflow path, maintaining the air pressure balance inside the drying chamber 1, and accelerating moisture evaporation. When the dried venison is dried, the operator controls and starts the servo motor 14 through the external PLC controller, causing the two side plates 4 to move away from each other and rise and fall. In structure 5, the power output end of servo motor 14 rotates simultaneously. When the power output end of servo motor 14 rotates, it drives lead screw 13 to rotate synchronously in the same direction. When lead screw 13 rotates, it is threadedly connected to the threaded hole on the upper surface of lifting block 12, so that lifting block 12 rises along guide rail 11. Lifting block 12 drives side plate 4, bottom plate 6, carrier box 17 and top plate 7 to rise as a whole. As the rising process proceeds, bottom plate 6 stops in sequence. When taking out venison, it starts from the top bottom plate 6 and goes down in sequence. When venison is put in, the operator controls and starts the power output end of servo motor 14 to reverse through external PLC controller. As lifting block 12 drives side plate 4, bottom plate 6, carrier box 17 and top plate 7 to fall as a whole, bottom plate 6 stops in sequence during the falling process. Venison is put up in sequence from the bottom bottom plate 6 until the lower surface of top plate 7 is in contact with the upper surface of drying box 1.

[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
