Description

Technical Field

[0001] The present invention relates to the technical field of pet food production devices, and in particular to a pet food production device with a circulating drying function. Background Art

[0002] Drying equipment in pet feed production is crucial for ensuring feed quality. Existing technologies primarily include hot air drying, microwave drying, and vibrating fluidized bed drying. Hot air drying uses hot air to evaporate moisture, offering simple operation but lengthy drying times. Microwave drying utilizes microwave energy to rapidly heat and evaporate moisture, preserving nutrients. Vibrating fluidized bed drying combines vibration with hot air to improve drying efficiency. When choosing a drying method, consider factors such as feed type, production efficiency, and cost.

[0003] For example, a pet food production device with a circulating drying function with publication number CN117016820B specifically discloses that it includes a support leg, the support leg is fixedly connected to a first fixed cylinder, the first fixed cylinder is fixedly connected to a first connecting frame and a fixed sleeve, the fixed sleeve is fixedly connected to a second connecting frame, the second connecting frame is fixedly connected to a feed hopper, the feed hopper is fixedly connected to a first fixed tube, the first fixed tube is rotatably connected to a first rotating tube, the first fixed cylinder is rotatably connected to a symmetrically distributed rotating plate, the rotating plate away from the second connecting frame is fixedly connected to a first outer gear ring, the first fixed cylinder is installed with a first motor, the output shaft of the first motor is fixedly connected to a transmission gear, and symmetrically distributed dumping racks are fixed between the symmetrically distributed rotating plates.

[0004] During operation, the high-temperature airflow blows over the feed in the existing drying device for pet feed production, flowing only through the surface of the feed. Since the high-temperature airflow only acts on the surface of the feed, the moisture inside the feed cannot be fully evaporated, resulting in uneven drying degrees inside and outside, affecting the overall quality of the feed. At the same time, to ensure uniform drying of the feed, it may be necessary to extend the drying time or increase the airflow temperature, which will lead to increased energy consumption. To solve the above problems, we propose a pet feed production device with a circulating drying function. Summary of the Invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Example 1

[0032] Reference Figure 1-8 As shown, a pet feed production device with a circulating drying function includes a box body 1, the upper end of the box body 1 is open, and support frames 3 are fixedly installed at both ends of the bottom of the box body 1. A discharge port 2 is opened at the lower end of the box body 1, and the inner wall of the box body 1 is set as an arc surface. A rotating drum 4 is set inside the box body 1, and the interior of the rotating drum 4 is hollow. A plurality of flip plates 5 distributed in a circular array are provided in the box body 1, and the flip plates 5 are set in a bent shape. The ends of the flip plates 5 are fixedly connected to the outside of the rotating drum 4. A plurality of gaps 15 are opened on the rotating drum 4, and the gaps 15 all pass through the rotating drum 4. A seal 6 is provided at the discharge port 2, which can block the discharge port 2. The upper end surface of the seal 6 is set to an arc surface and has the same curvature as the arc surface of the inner wall of the box body 1. Exhaust grooves 10 are provided on both sides of the box body 1. The exhaust grooves 10 all pass through the box body 1, and one end of the exhaust groove 10 is tilted upward. Connecting shafts 11 are fixedly installed at both ends of the rotating drum 4, and the ends of the connecting shafts 11 can be rotatably installed on the box body 1. An air supply mechanism is provided outside the box body 1, which is connected to the inner cavity of the rotating drum 4 and guides the high-temperature airflow into the rotating drum 4.

[0033] Among them, a magnetic plate 7 is fixedly installed at the bottom of the seal 6, and two iron sheets 8 are fixedly installed at intervals at the bottom of the box 1, and the magnetic plate 7 can be adsorbed on the iron sheet 8. Shock-absorbing pads are provided at the bottom of the support frame 3 to improve the stability of the device during operation. The edges of the box 1 are rounded to prevent the edges of the box 1 from scratching the staff. A handle 9 is fixedly installed at the bottom of the magnetic plate 7, and the magnetic plate 7 is moved by holding the handle 9. When the device is working, the discharge port 2 is blocked by the seal 6, and the magnetic plate 7 is adsorbed on the iron sheet 8. When discharging the material in the box 1, the seal 6 in the discharge port 2 is removed, the magnetic plate 7 is separated from the iron sheet 8, the discharge port 2 is in an open state, and the material in the box 1 can be discharged from the discharge port 2.

[0034] The end of the connecting shaft 11 extends outside the housing 1. The air supply mechanism includes an air duct 12, which is opened on one side of the connecting shaft 11 and communicates with the inner cavity of the rotating drum 4. A housing 13 is fixedly mounted on the outside of the housing 1, and the air duct 12 communicates with the inner cavity of the housing 13. A first motor 14 is disposed within the housing 13. A plurality of support bars 16 are fixedly mounted on the first motor 14, and the ends of the support bars 16 are fixed to the inner side of the housing 13. A filter plate 17 is fixedly mounted within the housing 13. The output shaft of the first motor 14 passes through the filter plate 17 and is rotatably mounted on the filter plate 17. A fan blade 18 is fixedly mounted on the output shaft end of the first motor 14. A heating wire 19 is disposed within the air duct 12. A support frame 20 is fixedly mounted within the housing 13. One end of the heating wire 19 is fixedly connected to the support frame 20. The housing 13 has an inlet 30. The heating wire 19 is configured in a spiral shape to increase the contact area between the heating wire 19 and the airflow within the air duct 12, thereby improving heating efficiency.

[0035] The pet food is added into the box body 1, and the sealing member 6 blocks the discharge port 2. The rotating drum 4 is driven to rotate, and the multiple flip plates 5 on the rotating drum 4 rotate. When the flip plates 5 rotate to the bottom end of the inner cavity of the box body 1, the flip plates 5 lift the pet food in the box body 1, and the pet food is accumulated on the flip plates 5. The pet food rises with the flip plates 5. When the flip plates 5 rotate to the upper end, the pet food slides on the flip plates 5. As the flip plates 5 continue to rotate, the pet food is separated from one end of the flip plates 5 and thrown out, and then falls to the inner wall of the box body 1. The pet food slides along the inner wall of the box body 1 to the bottom of the box body 1. In the above process, the pet food experiences a sliding and flipping state, and then the flip plates 5 continue to drive the pet food to repeat the above movement process, so that the pet food is continuously flipped.

[0036] At the same time, the first motor 14 drives the fan blades 18 to rotate, introducing external air into the housing 13. The air is filtered by the filter plate 17 to remove dust in the air, and the clean air is introduced into the housing 13, and then enters the inner cavity of the drum 4 through the air duct 12. The airflow in the air duct 12 is heated by the heating wire 19, so that the high-temperature airflow is introduced into the drum 4 and then discharged through the gap 15. The airflow discharged from the gap 15 blows on the pet food. With the pet food being continuously turned over, different positions of the pet food can be dried by the high-temperature airflow.

[0037] The device continuously supplies hot air into the chamber 1 and blows the heated air toward the pet food, achieving rapid and uniform drying. The hot air circulates within the device, continuously transferring heat to the food while simultaneously removing moisture from it. Compared to traditional drying methods, the high-temperature airflow used in this application can evenly affect different locations on the pet food surface, preventing areas of excessive drying or moisture, thereby ensuring uniform and consistent drying quality.

[0038] Example 2

[0039] Reference Figure 5-8 As shown, as another preferred embodiment of the present invention, the difference from Example 1 is that a driving mechanism is provided on one side of the housing 1, and the driving mechanism is connected to the connecting shaft 11 on one side. The driving mechanism is used to drive the flip plate 5 on the rotating drum 4 to rotate. The driving mechanism includes a support plate 21, which is fixedly mounted on the outside of the housing 1. A driven wheel 22 is provided in the support plate 21, and the driven wheel 22 is fixedly mounted on the end of the connecting shaft 11. Two spaced-apart chute 23 are fixedly mounted on the bottom of the support plate 21. A movable frame 24 is provided in the support plate 21. Slide blocks 29 are fixedly mounted on both sides of the movable frame 24. The slide blocks 29 are respectively slidably mounted in the chute 23. A first rack 25 is fixedly mounted on the upper end of the movable frame 24, and the first rack 25 is meshed with the driven wheel 22.

[0040] Among them, second racks 26 are fixedly connected on both sides of the movable frame 24, a second motor 27 is fixedly installed in the support plate 21, and an incomplete gear 28 is fixedly installed on the output shaft end of the second motor 27. The incomplete gear 28 is set in the movable frame 24, and the incomplete gear 28 is located between the two second racks 26 and can engage with the second racks 26.

[0041] The drum 4 is driven to rotate by the driving mechanism. Specifically, the second motor 27 drives the incomplete gear 28 to rotate, and the incomplete gear 28 intermittently drives the upper and lower second racks 26 to move, thereby driving the movable frame 24 to move back and forth along the direction of the slide 23. The first rack 25 on the movable frame 24 drives the driven wheel 22 to rotate back and forth, thereby driving the drum 4 to rotate back and forth, and the flip plate 5 on the drum 4 rotates synchronously. Figure 4 As shown, when the flip plate 5 rotates counterclockwise, the angle of the flip plate 5 rotating counterclockwise is greater than one circle, and the flip plate 5 can flip the pet food in the box 1. When the flip plate 5 rotates clockwise, it can drive the pet food to rise in the reverse direction and play the role of mixing the pet food.

[0042] Working principle:

[0043] The pet feed is added into the box body 1, the seal 6 blocks the discharge port 2, and the driving mechanism drives the drum 4 to rotate, and the multiple flip plates 5 on the drum 4 rotate. Specifically, the second motor 27 drives the incomplete gear 28 to rotate, and the incomplete gear 28 intermittently drives the upper and lower second racks 26 to move, thereby driving the movable frame 24 to reciprocate along the direction of the slide 23. The first rack 25 on the movable frame 24 drives the driven wheel 22 to reciprocate, thereby driving the drum 4 to reciprocate, and the flip plates 5 on the drum 4 rotate synchronously. Figure 4As shown, when the flip plate 5 rotates counterclockwise, the angle of the flip plate 5 rotating counterclockwise is greater than one circle, and the flip plate 5 can flip the pet food in the box 1. When the flip plate 5 rotates clockwise, it can drive the pet food to rise in the reverse direction and play the role of mixing the pet food.

[0044] During the counterclockwise rotation of the flip plate 5, when the flip plate 5 rotates to the bottom end of the inner cavity of the box body 1, the flip plate 5 lifts the pet food in the box body 1, and the pet food accumulates on the flip plate 5. The pet food rises with the flip plate 5. When the flip plate 5 rotates to the upper end, the pet food slides on the flip plate 5. As the flip plate 5 continues to rotate, the pet food is separated from one end of the flip plate 5 and thrown out, and then falls to the inner wall of the box body 1. The pet food slides along the inner wall of the box body 1 to the bottom of the box body 1. In the above process, the pet food experiences a sliding and flipping state, and then the flip plate 5 continues to drive the pet food to repeat the above movement process, so that the pet food is continuously flipped.

[0045] At the same time, the first motor 14 drives the fan blades 18 to rotate, introducing external air into the housing 13. The air is filtered by the filter plate 17 to remove dust in the air, and the clean air is introduced into the housing 13, and then enters the inner cavity of the drum 4 through the air duct 12. The airflow in the air duct 12 is heated by the heating wire 19, so that the high-temperature airflow is introduced into the drum 4 and then discharged through the gap 15. The airflow discharged from the gap 15 blows on the pet food. With the pet food being continuously turned over, different positions of the pet food can be dried by the high-temperature airflow.

[0046] When discharging the material in the box body 1 , the seal 6 in the discharge port 2 is removed, the magnetic plate 7 is separated from the iron sheet 8 , the discharge port 2 is in an open state, and the material in the box body 1 can be discharged from the discharge port 2 .

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
