[0029] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0030] Referring to Figures 1 - 5 , a drying device for pet food production includes a drying barrel assembly 10. The drying barrel assembly 10 includes an outer barrel 110 and an inner barrel 120 rotatably arranged in the outer barrel 110. The front sides of the outer barrel 110 and the inner barrel 120 are open. An air duct 130 is arranged in the inner barrel 120. Air outlet holes 131 are evenly distributed on the air duct 130. The rear end of the air duct 130 extends backward through the outer barrel 110 and the inner barrel 120 to the outside of the drying barrel assembly 10. A driving assembly 20 for driving the inner barrel 120 to rotate relative to the outer barrel 110 is arranged on the drying barrel assembly 10. Multiple arc-shaped screening grooves 122 coaxial with the inner barrel 120 are evenly distributed on the inner barrel 120. The arc-shaped screening grooves 122 penetrate through the inner barrel 120. A plurality of scraping assemblies 30 are arranged on the outer barrel 110. The scraping assemblies 30 can be inserted into any one of the arc-shaped screening grooves 122 to scoop out the materials.

[0031] The arc-shaped screening groove provided in the utility model can play a role in air circulation and screening materials, and the materials smaller than the width of the arc-shaped screening groove will fall into the space between the inner barrel and the outer barrel. During normal operation, as the inner barrel rotates, the scraping component can scrape out the materials blocked in the arc-shaped screening groove to avoid affecting air circulation and material passage.

[0032] The working principle of the utility model: When in use, the air duct 130 is connected to a hot air device. The hot air device uses an existing commercially available product, which conveys hot air into the air duct 130. The hot air enters the interior of the inner barrel 120 from the air outlet holes 131 to remove the excess moisture in the materials through heat, so as to achieve drying. During the drying process, the driving component 20 drives the inner barrel 120 to rotate relative to the outer barrel 110, so that the materials roll in the inner barrel 120, enabling the hot air to fully contact all the materials to improve the drying efficiency. At the same time, during the rotation of the inner barrel 120, the materials smaller than the width of the arc-shaped screening groove 122 fall into the space between the inner barrel and the outer barrel.

[0033] Furthermore, a discharge port 60 is provided at the rear side of the outer barrel 110. When it is necessary to clean the materials in the outer barrel 110, the entire drying barrel assembly 10 is tilted, so that the materials between the outer barrel 110 and the inner barrel 120 flow backward to the discharge port 60 and then fall out to the outside from the discharge port.

[0034] See Figure 4 , the scraping component 30 includes a moving rod 310. One end of the moving rod 310 close to the inner barrel 120 is provided with a material scraping member 320. The material scraping member 320 is movably inserted into the arc-shaped screening groove 122. An activity hole 113 is provided on the wall surface of the outer barrel 110 corresponding to the position of the moving rod 310. The moving rod 310 is movably inserted into the activity hole 113 and extends outward. A limiting member 340 is connected to the part of the moving rod 310 located outside the outer barrel 110. The limiting member 340 abuts against the outer side wall surface of the outer barrel 110. A spring 330 is sleeved on the moving rod 310 between the inner wall of the outer barrel 110 and the material scraping member 320.

[0035] The material scraping member 310 is in a spherical structure. Under the action of the spring 330, it can make the material scraping member 310 embed in the arc-shaped screening groove 122. As the inner barrel 120 rotates relative to the outer barrel 110, that is, the inner barrel 120 rotates relative to the material scraping member 310, so as to scrape out the materials blocked in the arc-shaped screening groove 122 through the material scraping member 310.

[0036] Furthermore, multiple groups of arc-shaped screening grooves 122 are provided in the utility model. The multiple groups of arc-shaped screening grooves 122 are arranged in a straight line along the axial direction of the inner barrel 120.

[0037] Each group of arc-shaped screening troughs 122 includes at least one. When there are two or more arc-shaped screening troughs 122 in each group, they are arranged along the circumferential direction of the inner barrel 120.

[0038] See Figure 2 , a rotating sleeve 123 is provided at the rear side of the inner barrel 120, an installation hole 112 is provided on the rear side wall surface of the outer barrel 110, and the rotating sleeve 123 is rotatably arranged in the installation hole 112; the air duct 130 is arranged through the rotating sleeve 123 and extends backward.

[0039] Furthermore, the rotating sleeve 123 is rotatably arranged in the installation hole 112 by using a bearing.

[0040] See Figure 2 , the air duct 130 is rotatably arranged in the rotating sleeve 123; a plurality of scraping blades 132 are provided on the air duct 130, and the driving assembly 20 is rotatably connected to the air duct 130 for driving the air duct 130 to rotate. The air duct 130 rotates relative to the inner barrel 120, and the material located in the inner barrel 120 can be scattered by the scraping blades 132, so that the material is dispersed, and the material can better contact with the air, improving the drying efficiency.

[0041] See Figure 2 , a first gear 210 is provided at the rear end of the air duct 130, and a second gear 220 is provided at the rear end of the rotating sleeve 123; the driving assembly 20 includes a first driving motor 200 fixedly arranged on the outer barrel 110, a third gear 230 and a fourth gear 240 are arranged on the motor shaft of the first driving motor 200, the third gear 230 meshes with the first gear 210, and the second gear 220 meshes with the fourth gear 240.

[0042] When the first driving motor 200 operates, it drives the third gear 230 and the fourth gear 240 to rotate, so as to drive the first gear 210 and the second gear 220 to rotate, thereby driving the air duct 130 and the rotating sleeve 123 to rotate, and the rotating sleeve 123 can drive the inner barrel 120 to rotate.

[0043] See Figure 2 , a first mating ring 111 is provided at the front side of the outer barrel 110, a second mating ring 121 is provided at the front side of the inner barrel 120, and the second mating ring 121 is rotatably connected to the first mating ring 111.

[0044] See Figure 2, a support assembly 50 rotatably engaged with the front end of the air duct 130 is provided inside the inner barrel 120; the support assembly 50 includes a fixed bracket 510 fixedly arranged inside the inner barrel 120, a support rod 530 is arranged on the fixed bracket 510, a rotating sleeve 520 is fixedly connected to the support rod 530, and the front end of the air duct 130 is rotatably arranged inside the rotating sleeve 520.

[0045] The support assembly 50 can support the front end of the air duct 130 and the air duct 130 can rotate relative to the support assembly 50.

[0046] See Figure 2 , further including a base 410, a vertical rod 420 is arranged on the base 410, and the upper end of the vertical rod 420 is hinged to the outer wall of the outer barrel 110; a telescopic element 430 is hinged to the base 410 on the front side of the vertical rod 420, and the telescopic end of the telescopic element 430 is hinged to the outer wall of the outer barrel 110.

[0047] In the present utility model, the telescopic element 430 is a cylinder.

[0048] Under the action of the telescopic element 430, it can drive the entire drying barrel assembly 10 to tilt forward or backward. Tilting forward can make the material flow forward from the inner barrel 120 until it is output to the outside. Tilting backward is to make the material located between the outer barrel 110 and the inner barrel 120 flow backward to the discharge port 60 and then fall out to the outside from the discharge port.
