Description

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] Pet food typically undergoes drying during processing to extend shelf life and improve taste. Currently, commonly used drying equipment employs hot air circulation combined with tray or drum structures to dry materials. However, existing drying equipment still has the following problems:

[0003] Insufficient turning of materials during the drying process leads to uneven drying. The equipment has a rigid structure, and the unloading process requires manual intervention or mechanical forced opening of the lid, which is cumbersome and poses a risk of burns.

[0004] Therefore, we propose a hot air drying device for pet food to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a hot air drying device for pet food.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot air drying device for pet food, comprising a housing, a hot air pipe, a main mesh plate, and a secondary mesh plate. The main mesh plate and the secondary mesh plate are rotatably connected by a connecting shaft, forming a complete mesh cylinder structure. The mesh cylinder structure is rotatably disposed within the housing. Electromagnets are respectively provided on the outer walls of the main mesh plate and the secondary mesh plate, and the positions of the two electromagnets correspond to each other.

[0007] The hot air duct is located at the central axis of the mesh cylinder structure.

[0008] Preferably, one end of the main mesh plate of the mesh cylinder structure is rotatably mounted on the box body and its outer wall is provided with a toothed ring. The outer wall of the box body is provided with a base, the base is provided with a motor, the output end of the motor is provided with a gear, and the toothed ring meshes with the gear teeth.

[0009] Preferably, the upper end of the outer wall of the housing is provided with a bracket, the hot air pipe is fixed on the bracket, and the other end of the hot air pipe passes through the central hole of the mesh cylinder structure and is located inside the mesh cylinder structure.

[0010] Preferably, the other end of the main mesh plate of the mesh cylinder structure is provided with a feed head, which is located on the box body and is connected to an exhaust port.

[0011] Preferably, the inner wall of the housing is provided with a sliding rail, and the outer wall of the electromagnet is provided with a sliding contact, the sliding contact being slidably connected to the sliding rail.

[0012] Preferably, the lower end of the outer wall of the box is provided with side plates symmetrically, and the lower surface of the side plates is provided with supporting legs symmetrically.

[0013] Preferably, the bottom of the inner wall of the box is designed in a funnel shape, and the bottom opening of the funnel and the feed head are both threaded with a cap.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] During use, this utility model pet food hot air drying equipment is connected to an external power source. At this time, the electromagnets are energized, and the opposite poles of the two electromagnets attract each other, so that the main screen plate and the auxiliary screen plate form a complete screen cylinder. Then, the cover of the feed head can be opened to introduce the pet food material to be dried into the screen cylinder structure through the feed head, and then the feed head is closed.

[0016] At this time, the hot air pipe is connected to the external hot air source. The hot air is blown into the mesh cylinder structure through the hot air pipe. Then the motor works and drives the mesh cylinder to rotate in the box under the meshing action of the gear teeth. The rotation of the mesh cylinder, together with the hot air, makes the material in the mesh cylinder evenly dried. During this process, the hot air flows through the mesh cylinder and finally carries the water vapor out of the box through the exhaust port.

[0017] After the material inside the screen cylinder is dried, the screen cylinder structure is controlled to stop rotating. The screen cylinder is stopped when the electromagnet is vertically downward. Then, the current direction of the two electromagnets is controlled so that the two electromagnets with the same poles repel each other. At this time, the secondary screen plate deflects on the main screen plate through the connecting shaft, so that the dried material falls from the gap between the secondary screen plate and the main screen plate into the box, and is finally discharged through the bottom opening of the box.

[0018] In this invention, the main mesh plate and the secondary mesh plate are attracted and attached by an electromagnet to form a closed rotating mesh cylinder for drying operations. After drying, the polarity of the electromagnet is changed so that like poles repel each other, causing the secondary mesh plate to deflect and open, disintegrating the mesh cylinder structure and forming a discharge channel. The material falls automatically, achieving rapid unloading. Driven by rotation, the mesh cylinder, combined with hot air circulation, keeps the material tumbling and heating evenly, improving the drying effect. It is suitable for pet food in various forms such as granules and strips. Attached Figure Description

[0025] 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.

[0026] Example 1

[0027] like Figures 1-4 As shown, the present invention proposes a hot air drying device for pet food, comprising a housing 1, a hot air pipe 5, a main mesh plate 9, and a secondary mesh plate 14. The main mesh plate 9 and the secondary mesh plate 14 are rotatably connected by a connecting shaft 15, forming a complete mesh cylinder structure. The mesh cylinder structure is rotatably disposed within the housing 1. A feed head 13 is rotatably disposed at the other end of the main mesh plate 9, and the feed head 13 is located on the housing 1. An exhaust port 12 is connected to the feed head 13. Electromagnets 10 are respectively provided on the outer wall, and the positions of the two electromagnets 10 are corresponding. The hot air pipe 5 is located at the central axis of the mesh cylinder structure. During the use of this pet food hot air drying equipment, when connected to an external power source, the electromagnets 10 are energized, and the opposite poles of the two electromagnets 10 attract each other, so that the main mesh plate 9 and the secondary mesh plate 14 form a complete mesh cylinder. Then the cover of the feed head 13 can be opened to introduce the pet food material to be dried into the mesh cylinder structure through the feed head 13, and then the feed head 13 is closed.

[0028] At this time, the hot air pipe 5 is connected to the external hot air source. The hot air is blown into the mesh cylinder structure through the hot air pipe 5. Then the mesh cylinder is controlled to rotate. The rotation of the mesh cylinder, in conjunction with the hot air, makes the material in the mesh cylinder evenly dried. During this process, the hot air flows through the mesh cylinder and finally carries water vapor out of the box 1 from the exhaust port 12.

[0029] After the material inside the mesh cylinder is dried, the mesh cylinder structure is controlled to stop rotating. The mesh cylinder is stopped when the electromagnet 10 is vertically downward. Then, the current direction of the two electromagnets 10 is controlled so that the two electromagnets 10 with the same poles repel each other. At this time, the auxiliary mesh plate 14 is deflected on the main mesh plate 9 through the connecting shaft 15, so that the dried material falls into the box 1 from the gap between the auxiliary mesh plate 14 and the main mesh plate 9. Then, the bottom opening of the box 1 is opened and the material is discharged through the bottom opening of the box 1.
