Technical Field

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

[0002] A search revealed Chinese patent CN220602029U, which discloses a drying and shaping device for processing granular pet food. This device relates to the field of pet food processing technology and includes a drying chamber with supporting legs fixedly connected to its bottom. A blower mechanism is located on the left side of the drying chamber. Heating wires are installed inside the drying chamber, and a placement cylinder is fixedly connected to its inner wall. The drying chamber also includes a turning mechanism and a stirring mechanism. The turning mechanism turns the granular pet food inside the placement cylinder, and the stirring mechanism agitates it. This combination of turning and stirring mechanisms ensures even heating of the granular pet food, avoiding the drawback of hot air only reaching the outermost layer when too much pet food is placed inside. This ensures even heating and improves the drying efficiency of the granular pet food.

[0003] The drying and molding equipment for granulated pet food processing in the aforementioned patent has the following shortcomings: after the drying process is completed, the pet food material is located deep inside the placement cylinder, making it difficult to remove the pet food material. The operation is relatively complicated and requires a lot of time and effort, increasing the labor intensity of employees and significantly affecting the efficiency of the entire production process. Therefore, it is necessary to design a hot air drying equipment for pet food to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hot air drying device for pet food.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hot air drying device for pet food includes a drying chamber. A motor is installed on one side of the drying chamber, and a rotating shaft is fixedly connected to the output end of the motor. Two shovels are fixedly connected to the outer wall of the rotating shaft, and a grid is fixedly connected to the inner wall of the shovels. Two semi-circular plates are sleeved on the rotating shaft, and the two semi-circular plates are respectively located on both sides of the shovels. Two connecting rods are fixedly connected to the same side of each of the two semi-circular plates. Two slots are opened on the connecting rods, and insert rods are installed in the slots. The two insert rods at the same end are fixedly connected to the same extension rod. A circular groove is opened on one side of the drying chamber, and a circular plate is installed in the circular groove. An annular slide rail is sleeved on the circular plate, and the annular slide rail is fixedly connected to the drying chamber. The connecting rods pass through the circular plate. Due to the use of semi-circular plates... This invention employs a technique to move pet food materials for discharge. After drying, an extension rod is installed on a connecting rod to move a semi-circular plate, allowing the pet food materials to be discharged from the discharge pipe. The semi-circular plate moves along the rotating shaft, shovel, and grid, preventing material residue from remaining in the drying chamber. This effectively solves the problem mentioned in the background art where, after drying, the pet food materials are deep within the placement cylinder, making removal difficult, complex, time-consuming, and labor-intensive, thus increasing employee workload and significantly impacting overall production efficiency. The invention thus achieves the technical effect of significantly improving the speed and convenience of material removal, reducing employee workload, and substantially enhancing overall production efficiency.

[0012] As a further embodiment of this utility model, a support plate is fixedly connected to the bottom of the motor, and the support plate is fixedly connected to the drying oven.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a semi-circular plate to move pet food materials for discharge. After drying, an extension rod is installed on the connecting rod to move the semi-circular plate, allowing the pet food materials to be discharged from the discharge pipe. The semi-circular plate moves along the rotating shaft, shovel, and grid, preventing material residue from remaining in the drying chamber.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and implementing regulations.

[0023] Reference Figure 1 - Figure 5 A hot air drying device for pet food includes a drying chamber 1. A motor 2 is installed on one side of the drying chamber 1. A rotating shaft 3 is fixedly connected to the output end of the motor 2. Two shovels 4 are fixedly connected to the outer wall of the rotating shaft 3. The shovels 4 scoop up the pet food inside the drying chamber 1. A grid 5 is fixedly connected to the inner wall of the shovels 4. After the shovels 4 scoop up the pet food, when the shovels 4 move to the top, the pet food will fall onto the grid 5 under the action of gravity and eventually fall off the grid 5, causing the pet food to scatter. Two semi-circular plates 6 are sleeved on the rotating shaft 3. After the drying process is completed, the two semi-circular plates 6 are moved. The pet food inside the drying chamber 1 is pushed to the position of the discharge pipe 18 for discharge. Two semi-circular plates 6 are respectively set on both sides of the shovel plate 4. Two connecting rods 7 are fixedly connected to the same side of the two semi-circular plates 6. Two slots 8 are opened on the connecting rods 7, and insert rods 9 are set in the slots 8. The two insert rods 9 at the same end are fixedly connected to the same extension rod 10. When the semi-circular plates 6 are moved, the extension rod 10 is installed and then the semi-circular plates 6 are pushed to perform the discharge operation. A circular groove is opened on one side of the drying chamber 1. A circular plate 11 is set in the circular groove on the drying chamber 1. The circular plate 11 is fitted with an annular sliding plate. Rail 12, when the shovel plate 4 and grid 5 rotate to turn the pet food, can drive the semi-circular plate 6 to rotate. The semi-circular plate 6 will drive the connecting rod 7 to rotate, and the connecting rod 7 will drive the circular plate 11 to rotate. The circular plate 11 will rotate within the annular slide rail 12, ensuring the stability of the rotation of the two semi-circular plates 6. The annular slide rail 12 is fixedly connected to the drying box 1. The connecting rod 7 passes through the circular plate 11. Because the technology of using semi-circular plates to push the pet food material to move for discharge is adopted, after the drying work is completed, the extension rod is installed on the connecting rod to push the semi-circular plate to move the pet food material to the discharge pipe. The material is discharged at the designated location, and the semi-circular plate moves along the rotating shaft, shovel plate, and grid to prevent material residue from remaining in the drying chamber. This effectively solves the problem mentioned in the background technology that after the drying process is completed, the pet food material is located deep in the placement cylinder, making it difficult and complicated to remove the pet food material. This requires a lot of time and effort, increases the labor intensity of employees, and significantly affects the efficiency of the entire production process. As a result, the technology effectively improves the speed and convenience of material removal, reduces the labor intensity of employees, and significantly improves the overall production efficiency.

[0024] In this embodiment, a pin hole 13 is provided on the connecting rod 7, and a pin 14 is provided in the pin hole 13. When the semicircular plate 6 moves to the end of the drying oven 1 away from the motor 2, the pin 14 is inserted into the pin hole 13 to restrict the position of the semicircular plate 6.

[0025] In this embodiment, a base 15 is fixedly connected to the bottom of the drying oven 1.

[0026] In this embodiment, a feeding pipe 16 is provided at the top of the drying chamber 1, and a first sealing plate 17 is threadedly connected to the feeding pipe 16. A discharge pipe 18 is provided at the bottom of the drying chamber 1, and a second sealing plate 19 is threadedly connected to the discharge pipe 18. The first sealing plate 17 seals the feeding pipe 16, and the second sealing plate 19 seals the discharge pipe 18 to prevent accidental discharge of materials during the process of turning over pet food.

[0027] In this embodiment, a shell 20 is fixedly connected to the top of the drying oven 1, a heating wire 21 is installed on the inner wall of the shell 20, and a fan 22 is installed on the top of the shell 20.

[0028] In this embodiment, a valve 23 is installed on the side of the drying chamber 1 near the motor 2. The exhaust volume is adjusted by the valve 23 to avoid excessive internal hot air that prevents the addition of hot air, and also to avoid the internal temperature from being too low due to the hot air being discharged too quickly.

[0029] In this embodiment, a support plate 201 is fixedly connected to the bottom of the motor 2, and the support plate 201 is fixedly connected to the drying oven 1.

[0030] Working Principle: When using this device, the pet food to be dried is injected into the drying chamber 1 through the feeding pipe 16. Then, the first sealing plate 17 is screwed onto the feeding pipe 16. An external power supply heats the heating wire 21, and the fan 22 and motor 2 are started. The fan 22 draws outside air into the drying chamber 1, which is heated by the heating wire 21 and blown into the drying chamber 1, onto the pet food for drying. The output of the motor 2 drives the rotating shaft 3 to rotate, which in turn drives the shovel 4 to rotate. The shovel 4 then drives the grid 5 to rotate, lifting the pet food from inside the drying chamber 1. As the pet food is moved to the top of the drying chamber 1, it falls under gravity, passing over the grid 5 and landing back at the bottom of the drying chamber 1. During this descent, the pet food disperses, preventing it from piling up. The dispersed pet food also helps to dry. Sufficient contact with hot air ensures uniform drying. The shovel plate 4 and grid 5 continuously turn the pet food over, improving the drying effect and efficiency. After drying is complete, turn off the fan 22, unscrew the second sealing plate 19 and remove it. Take out the extension rod 10 and insert the insertion rod 9 on the extension rod 10 into the slot 8. Then push the extension rod 10 to move it towards the motor 2. The movement of the extension rod 10 will drive the insertion rod 9 to move, which in turn will drive the connecting rod 7 to move. The connecting rod 7 will then drive the semicircular plate 6 to move. The semicircular plate 6 will move along the rotating shaft 3, the shovel plate 4 and the grid 5, pushing the pet food inside the drying chamber 1 to the end of the drying chamber 1 near the discharge pipe 18. Place the container for collecting the pet food under the discharge pipe 18 to receive the food, thus completing the discharge process. Continue the drying process using the same steps.
