Abstract
Description
Technical Field
[0001] This utility model relates to the field of pet food raw material processing technology, and in particular to a rapid maturation device for pet food raw materials. Background Technology
[0002] A pet food ingredient maturation device is a core processing equipment specifically designed for handling pet food ingredients. Its main function is to mature raw ingredients (such as meat, grains, and vegetables) through heating or other physical methods. This process not only effectively kills any pathogenic microorganisms that may be present in the ingredients, ensuring food safety, but also gelatinizes the starch and denatures the proteins, thereby improving the pet's digestibility and absorption of its nutrients. Depending on different process requirements, maturation devices come in various forms, including cooking pots, ovens, and extrusion maturation machines. Their common goal is to provide pets with safe and easily digestible basic food ingredients.
[0003] Traditional curing equipment typically uses a fixed placement frame. Because it lacks an automatic lifting function, the distance between the steam nozzle and the top surface of the material remains constant regardless of the material height. If the material is piled too high, the steam may directly and forcefully impact the material, causing localized overheating or damage. If the material is too low, the steam may not be able to effectively reach the upper layer. In addition, traditional curing equipment may have only a few steam nozzles or an uneven nozzle layout, resulting in uneven steam distribution within the chamber. Some areas of the material may not be heated enough, while other areas may be overheated, leading to poor overall curing uniformity. Utility Model Content
[0004] The purpose of this invention is to provide a device for rapidly cooking pet food ingredients to solve the aforementioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A rapid maturation device for pet food ingredients includes a maturation box, multiple mounting racks, and multiple ventilated placement frames. Multiple mounting slots are provided at the front and rear ends of both sides of the inner wall of the maturation box. A threaded rod is installed inside each mounting slot on one side, and a second servo motor is fixedly connected to the inner bottom surface of each mounting slot on the other side. The output ends of the second servo motors are fixedly connected to the middle of the lower end of the threaded rod. A guide rod is fixedly connected inside each mounting slot on the other side. Sliding blocks are fitted onto the outer walls of both the threaded rod and the guide rod. The outer walls of the adjacent sides of the sliding blocks are connected to the front and rear ends of the outer walls of the mounting racks. The mounting frame is fixedly connected, with sliding grooves on the outer walls of adjacent sides. Sliding plates are fixedly connected to both sides of the outer wall of the ventilated placement frame. The outer walls of the sliding plates slide against the inner walls of the sliding grooves. A steam generator is fixedly connected to one side of the upper surface of the curing box. A conveying pipe is connected through the exhaust port of the steam generator. Multiple steam pipes are connected through the other side of the conveying pipe. The other side of each steam pipe penetrates the curing box into its interior. A nozzle is connected through the lower end of each steam pipe. The steam pipes and nozzles are located at the upper end of the ventilated placement frame.
[0006] Furthermore, the upper surface of the curing box is provided with multiple ventilation slots, and a protective shell is fixedly connected to the middle of the upper surface of the curing box. A first servo motor is fixedly connected to the inner bottom surface of the protective shell. The output end of the first servo motor passes through the curing box to the interior of the upper end of the curing box and is fixedly connected to a fan blade. A filter plate is provided at the lower end of the fan blade. The outer wall of the filter plate is fixedly connected to the inner wall of the middle of the upper end of the curing box.
[0007] Furthermore, a sealing door is hinged to the other side of the front end of the curing box via a hinge joint. A door handle is fixedly connected to the outer wall of one side of the front end of the sealing door, and a transparent observation window is fixedly connected to the inner wall of the other side of the sealing door. The outer wall of the sealing door is tightly fitted to the inner wall of the front end of the curing box.
[0008] Furthermore, a PLC control panel is fixedly connected to the outer wall on the other side of the curing tank.
[0009] Furthermore, the upper ends of the threaded rods on one side are rotatably connected to the inner top surface of the mounting groove, the outer walls of the sliding blocks are slidably fitted to the inner wall of the mounting groove, the inner walls of the sliding blocks on one side are threadedly connected to the outer wall of the threaded rod, and the inner walls of the sliding blocks on the other side are slidably fitted to the outer wall of the guide rod.
[0010] Furthermore, the outer walls of the mounting frame are all in close contact with the inner wall of the curing box, and the outer walls of the ventilated placement frame are all in close contact with the inner wall of the mounting frame.
[0011] Furthermore, a temperature sensor is installed on one side of the inner wall of the curing chamber.
[0012] Compared with the prior art, the pet food raw material rapid cooking device proposed in this utility model has the following beneficial effects: the threaded rod is driven to rotate by the second servo motor, and the mounting frame can be automatically raised and lowered, thereby adjusting the distance between the material in the placement frame and the steam nozzle above. Since different types, shapes or loading amounts of raw materials will cause changes in the height of the material, this adjustment ensures that no matter how high the material is stacked, its upper surface can always maintain an optimal working distance with the nozzle, avoiding the problem of insufficient steam action when the material is too high, or the problem of local overheating damage caused by direct steam impact when the material is too low. In addition, the layout of multiple steam pipes and nozzles, combined with the design of the placement frame, helps the steam to be evenly distributed to the material in the box, reducing heating dead zones and improving the uniformity of cooking.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] Reference Figure 3 , Figure 5 and Figure 6 This utility model provides a rapid maturation device for pet food ingredients, including a maturation box 1, multiple mounting racks 6, and multiple breathable placement frames 7. Multiple mounting slots 104 are provided at the front and rear ends of both sides of the inner wall of the maturation box 1. A threaded rod 501 is provided inside each mounting slot 104 on one side. A second servo motor 5 is fixedly connected to the inner bottom surface of each mounting slot 104 on one side. The output end of each second servo motor 5 is fixedly connected to the middle of the lower end of the threaded rod 501. A guide rod 502 is fixedly connected inside each mounting slot 104 on the other side. Sliding blocks 503 are fitted onto the outer walls of both the threaded rod 501 and the guide rod 502. The outer walls of the sliding blocks 503 on adjacent sides are connected to the outer walls of the mounting racks 6 on both sides. The front and rear ends are fixedly connected. The outer walls of the mounting frame 6 on both sides are provided with sliding grooves 601. The outer walls of the ventilated placement frame 7 are fixedly connected with sliding plates 701. The outer walls of the sliding plates 701 slide against the inner walls of the sliding grooves 601. A steam generator 4 is fixedly connected to one side of the upper surface of the curing box 1. The exhaust port of the steam generator 4 is connected to a conveying pipe 401. Multiple steam pipes 402 are connected to the other side of the conveying pipe 401. The other side of the steam pipes 402 penetrates the curing box 1 to the interior of the curing box 1. The lower end of the steam pipes 402 is connected to a nozzle 403. The steam pipes 402 and the nozzles 403 are located at the upper end of the ventilated placement frame 7.
[0017] The second servo motor 5 drives the threaded rod 501 to rotate, which in turn moves the sliding block 503 and the mounting bracket 6 up and down, thus achieving automated lifting and lowering of the mounting bracket 6. This allows for adjustment of the distance between the material and the steam nozzle 403. The height of pet food ingredients in the placement box may vary depending on the type, shape, or loading density of the ingredients. By adjusting the height of the mounting bracket 6, it can be ensured that no matter how high the material is stacked in the placement box, its upper surface maintains a relatively fixed and optimized working distance from the steam nozzle 403. This avoids insufficient steam action due to the material being too high, or direct steam impact on the material surface due to the material being too low. To prevent localized overheating or damage, the high-temperature steam generated by the steam generator 4 is directly sprayed onto the raw materials on the placement frame through the conveying pipe 401, steam pipe 402, and nozzle 403. Steam has the characteristics of large heat capacity and high heat transfer efficiency, which can achieve rapid heating and maturation of the raw materials. The design of multiple steam pipes 402 and nozzles 403, together with the layout of the placement frame, helps to distribute the steam more evenly to the materials in different areas of the box, reduce heating dead zones, and improve the uniformity of maturation. In addition, the design of the ventilated placement frame 7 allows steam to penetrate and contact the materials, and also facilitates the evaporation and discharge of moisture generated by the materials themselves during the maturation process.
[0018] Reference Figure 2 , Figure 3 and Figure 4The upper surface of the curing box 1 is provided with multiple ventilation slots 102. A protective shell 103 is fixedly connected to the middle of the upper surface of the curing box 1. A first servo motor 3 is fixedly connected to the inner bottom surface of the protective shell 103. The output end of the first servo motor 3 passes through the curing box 1 to the interior of the upper end of the curing box 1 and is fixedly connected to a fan blade 301. A filter plate 302 is provided at the lower end of the fan blade 301. The outer wall of the filter plate 302 is fixedly connected to the inner wall of the middle of the upper end of the curing box 1. The ventilation slots 102 serve as a passage for air circulation. The ventilation channel allows for the exchange of hot and humid air inside the chamber with the outside environment. The fan blades 301 are driven to rotate by the first servo motor 3, which forces the hot and humid air inside the chamber to be discharged through the ventilation channel 102. At the same time, it may draw in relatively dry or slightly cooler air. The downward airflow helps to distribute the heat more evenly to all corners of the chamber, reducing temperature dead zones and making all materials heat more uniformly. In addition, the filter plate 302 can filter out fine dust, hair or other impurities carried in the air entering from the ventilation channel 102.
[0019] Reference Figure 1 , Figure 2 and Figure 5A sealing door 2 is hinged to the other side of the front end of the curing chamber 1 via a hinge joint. A door handle 201 is fixedly connected to the outer wall of one side of the front end of the sealing door 2, and a transparent observation window 202 is fixedly connected to the inner wall of the other side of the sealing door 2. The outer wall of the sealing door 2 fits tightly against the inner wall of the front end of the curing chamber 1. The door handle 201 provides a convenient and safe way to open and close the sealing door 2. Operators do not need to directly contact the edge of the sealing door 2, which may be hot or pressurized, reducing the risk of burns or accidental loosening. The tight fit design effectively prevents heat loss from the inside of the curing chamber 1, improving energy efficiency and reducing the waste of steam or heat energy. In addition, the transparent observation window 202 allows operators to intuitively observe the curing status and arrangement of the materials inside the chamber without opening the sealing door 2, and can even check for any abnormalities. A PLC control panel 101 is fixedly connected to the outer wall of the other side of the curing chamber 1. The PLC control panel 101 is used to control the operation of the entire equipment. The upper end of the threaded rod 501 on one side is rotatably connected to the inner top surface of the mounting groove 104. The outer walls of the moving blocks 503 are all slidably fitted against the inner walls of the mounting grooves 104. The inner walls of one side of the sliding blocks 503 are threadedly connected to the outer walls of the threaded rods 501, and the inner walls of the other side of the sliding blocks 503 are all slidably fitted against the outer walls of the guide rods 502. This design makes the movement of the mounting brackets 6 and the ventilated placement frames 7 driven by the sliding blocks 503 more stable. The outer walls of the mounting brackets 6 and 104 are all tightly fitted against the inner walls of the curing box 1, and the outer walls of the ventilated placement frames 7 are all tightly fitted against the inner walls of the mounting brackets 6. This design ensures that the mounting brackets 6 drive the placement frames 104 to move smoothly. During the lifting and lowering process, the frame can move stably along the inner wall of the curing box 1, reducing gaps and helping the steam to be distributed more evenly in the curing box 1. A temperature sensor is installed on one side of the inner wall of the curing box 1. The temperature sensor can measure the temperature at a specific location in the curing box 1 in real time and accurately. The control system can automatically adjust the steam supply, heating power, or open / close the exhaust valve of the steam generator 4 based on the temperature data fed back by the sensor, so as to maintain the temperature inside the box within the set curing process requirements and ensure that the curing process is stable and controllable.
[0020] The working principle of this utility model is as follows: First, the operator places the pet food raw materials to be cooked into the ventilated placement frame 7 and places the placement frame on the mounting frame 6. After closing the sealing door 2, the PLC control panel 101 starts the system, and the second servo motor 5 starts working, driving the threaded rod 501 to rotate. Through the cooperation of the sliding block 503 and the guide rod 502, the mounting frame 6 and the placement frame on it are automatically raised and lowered to the preset optimal height, ensuring that the upper surface of the material in the frame maintains a uniform and optimized distance from the steam nozzle 403 above. Then, the steam generator 4 generates high-temperature steam, which is transported to the box through the conveying pipe 401 and multiple steam pipes 402, and then sprayed... The steam generator 403 sprays evenly onto the material, utilizing the efficient heat transfer characteristics of steam to quickly heat and cook the raw materials. At the same time, the first servo motor 3 drives the fan blades 301 to rotate, forcing the hot and humid air inside the chamber to be discharged through the ventilation slots 102 and filtered through the filter plate 302. This not only helps to dissipate heat and prevent excessive humidity, but also promotes a uniform temperature distribution inside the chamber. The temperature sensor monitors the temperature inside the chamber in real time and feeds the data back to the PLC control panel 101. The panel then precisely controls components such as the steam generator 4 to ensure that the cooking process is carried out stably within the set temperature range until the ideal cooking effect is achieved. The entire process is highly automated and the cooking efficiency is fast and uniform.
