[0002] Application document CN217483163U discloses a drying device for pet food production, relating to the field of production equipment technology. It includes a base, a drying chamber mounted on the upper surface of the base, an installation sleeve mounted on the inner surface of the drying chamber, an installation rod mounted on the inner surface of the installation sleeve, several installation seats mounted on the outer surface of the installation rod, a stirring rod mounted on the outer surface of the installation seats, auger blades mounted on the outer surface of the stirring rod, a transmission gear mounted on the outer surface of the installation rod, a gear rack mounted on the outer surface of the transmission gear, and a positioning sleeve mounted on the inner surface of the drying chamber. The outer surface of the installation rod is connected to the inner surface of the positioning sleeve. By controlling a stirring motor, the meshing between the power gear and the gear rack, as well as the meshing between the transmission gear and the gear rack, drives the installation rod to rotate, thereby driving the stirring rod and the auger blades to rotate, thus uniformly stirring the pet food and ensuring even drying, which improves the drying effect of the drying device.

[0003] However, the aforementioned equipment is inconvenient to add too much feed at once, otherwise the feed will pile up and be difficult to dry completely. Therefore, it is necessary to add feed frequently and in small amounts, which increases the number of operations for the user. This is not only time-consuming and labor-intensive, but also affects the feed feeding efficiency, resulting in low feed drying efficiency. Therefore, we propose a drying equipment for pet food production. Summary of the Invention

This ensures the drying time of the feed, thereby ensuring the drying effect of the feed and the use effect of the equipment, which is conducive to the promotion and use of the equipment.

[0029] Please see Figure 6 The top of the material preparation cylinder 21 is hinged to a cylinder cover 5, and a handle 6 is fixedly installed on the top of the cylinder cover 5.

[0030] Please see Figure 11 A scraper 7 is fixedly installed between the front and rear inner walls of the drying box 1. The scraper 7 abuts against the conveyor belt 33. Through the cooperation of the scraper 7 and the collection box 12, the scraper 7 can scrape off the feed powder adhering to the conveyor belt 33 and collect it into the collection box 12.

[0033] Please see Figure 4 and Figure 11 The front side of the drying box 1 is provided with a discharge chute, and a collection box 12 that fits into the discharge chute is placed on the bottom inner side of the drying box 1. A handle 13 is fixedly installed on the outer front surface of the collection box 12.

[0034] Working principle: During material preparation, open the cylinder cover 5, add feed into the material preparation cylinder 21, close the cylinder cover 5 to complete the material preparation. Before starting the equipment, preheat the internal space of the drying chamber 1 by controlling the hot air blower 41 to start. The hot air blower 41 generates hot air, which is injected into each distribution plate 42 through each air pipe 44, and then sprayed into the interior of the drying chamber 1 from multiple sets of air outlets 43 on each distribution plate 42. After preheating, according to the required feeding rate of the feed, first control the second motor 295 to start. The second motor 295 drives the gear 296 to rotate, which in turn drives the gear ring 293 to rotate and move the movable plate 293. 92. Rotate a certain angle until the material discharge holes on the movable plate 292 and the fixed plate 291 overlap in the vertical direction. Control the size of the overlap, i.e., control the feed feeding rate. After adjustment, control the equipment operation, i.e., control the first motor 214 and the third motor 31 to start synchronously. The third motor 31 will drive the two sets of transmission rollers 32 to rotate synchronously through the conveyor belt 33, driving the conveyor belt 33 to operate. The first motor 214 will drive the actuating component 215 to rotate continuously. The actuating component 215 will periodically actuate the paddle 216. Within one actuation cycle, it will first start the feed preparation. The cylinder 21 achieves micro-rotation by sliding on the limiting ring 24 and the support ring 22 through the two sets of first sliding sleeves 26 and two sets of second sliding sleeves 27 respectively. When it rotates to a certain angle, the two sets of first sliding sleeves 26 will compress the corresponding springs 211. Before the end of this turning cycle, that is, before the next turning, the rebound action of the two sets of springs 211 will drive the feed cylinder 21 to rotate back to its original position. This process repeats, achieving high-frequency vibration of the feed cylinder 21, which in turn shakes the feed inside the feed cylinder 21, causing the feed to continuously fall and fall onto the conveyor belt 33 in the drying box 1 through the material control mechanism 29. The falling feed will then be conveyed on the conveyor belt 33. The hot air blown out by the drying mechanism 4 directly dries the feed. The feed is dried as it falls from the conveyor belt 33 and is collected in the collection box 12. During this process, the scraper 7, which is close to the conveyor belt 33, scrapes off any powder or residue from the feed and collects it in the collection box 12. This process continues until the feed in the feed hopper 21 is completely dried. Before unloading, the partition plate 8 is slid into the drying chamber 1 by the handle 9 to separate the space where the collection box 12 is located. Then, the collection box 12 is pulled out to unload the feed and empty the dried feed. The feed can then be put back and the above drying steps can be repeated.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
