Description

Technical Field

[0001] This invention belongs to the field of pet food technology, specifically relating to a low-temperature fresh meat dehydration production system and process for pet food. Background Technology

[0002] Pet food is a general term encompassing various cat and dog foods used to feed pets. The current pet food market is vast and rapidly expanding. In existing pet food production, if meat is used as a raw material, it is generally produced by purchasing meat meal, which is formed through high-temperature dehydration (HTDH). HTDH dehydration of meat meal involves processes exceeding 200°C, causing the separation of oil and water in the meat, resulting in the loss of nutrients such as fats and affecting the taste of the pet food. Furthermore, meat meal and other raw materials are usually purchased externally, not produced by the pet food manufacturers themselves, leading to a lack of control over the meat source and consequently, uncontrollable product quality. If fresh meat is directly mixed with other ingredients to produce pet food, the moisture content of the fresh meat is difficult to control, making extrusion impossible and ultimately compromising the quality of the final product. Summary of the Invention

[0017] like Figure 1-3 As shown, the pet food low-temperature fresh meat dehydration production system includes, in sequence, a batching bin 101, a batching scale 102, a mixer 103, an ultrafine pulverizer 104, a forming bin 105, a forming machine 108, a drying oven 109, a spraying roller 110, a first cooler 111, and a finished product bin 112. The batching bin 101 includes multiple independent bins 113, one of which is a dehydrated fresh meat bin 114. The dehydrated fresh meat bin 114 is connected to a fresh meat dehydration production line. The fresh meat dehydration production line includes, in sequence, a crusher 115, a low-temperature dehydration device 100, and a second cooler 106. The outlet of the second cooler 106 is connected to the dehydrated fresh meat bin 114.

[0018] Furthermore, the crusher 115 is connected to the low-temperature dehydration device 100 through the first conveying mechanism, the low-temperature dehydration device 100 is connected to the second cooler 106 through the second conveying mechanism, and the second cooler 106 is connected to the dehydrated fresh meat bin 114 through the third conveying mechanism. The batching scale 102 is equipped with a first receiving hopper 116, which is weighed by the batching scale 102. The bin 113 is connected to batching pipes 117, which extend above the first receiving hopper 116. The first receiving hopper 116 is connected to a mixer 103, which is connected to a pulverizing chamber 118 via a fourth conveying mechanism. The pulverizer 104 is located below the pulverizing chamber 118 and is connected to a forming chamber 105 via a fifth conveying mechanism. The molding machine 108 is located below the molding chamber 105. The molding machine 108 is connected to the drying chamber 109 via a hoist. The drying chamber 109 is connected to the spraying roller 110 via a conveyor and a hoist in sequence. The spraying roller 110 is connected to the first cooler 111 via a hoist. The first cooler 111 is connected to the finished product chamber 112 via a sixth conveying mechanism.

[0019] Furthermore, the low-temperature dehydration device 100 includes an outer cylinder 1 and an inner cylinder 2. The inner cylinder 2 is located inside the outer cylinder 1 and is driven to rotate by a rotary drive mechanism. The circumferential surface of the inner cylinder 2 is covered with mesh holes. One end of the outer cylinder 1 has an upward-facing external feed inlet 3, which is covered with a feed cylinder cover 4. The other end of the outer cylinder 1 has a downward-facing external feed inlet 5, which is covered with a discharge cylinder cover 6. One end of the inner cylinder 2 has an upward-facing internal feed inlet 7, which corresponds to the external feed inlet 3. The other end of the inner cylinder 2... One end of the inner cylinder 2 has a downward-facing inner outlet 8, which corresponds to the outer outlet 5. Sealing cylinders 9 are movably fitted onto both ends of the inner cylinder 2 by a translational drive mechanism, covering either the inner inlet 7 or the inner outlet 8. The outer cylinder 1 has an exhaust port 10 and an air distribution pipe located below the inner cylinder 2. The air distribution pipe is connected to the exhaust port 10 via a return pipe 11, on which a dehumidifier 12, a circulating fan 13, and a heater 14 are installed. The dehumidifier 12 can be an existing condenser dehumidifier, or other suitable type. The circulating fan 13 allows for airflow circulation within the outer cylinder 1. The heater 14 heats the circulating airflow, stabilizing the temperature within the outer cylinder 1 between 90-100℃, achieving a lower temperature dehydration process for fresh meat compared to traditional dehydration processes above 200℃. The translational drive mechanism moves the sealing cylinder 9, exposing the inner feed inlet 7, allowing fresh meat to be dehydrated to be placed into the inner cylinder 2 through the outer feed inlet 3. Then, the sealing cylinder 9 moves to cover the inner feed inlet 7. The inner cylinder 2 rotates continuously during the dehydration process, turning the fresh meat and improving dehydration efficiency. Hot airflow gradually carries away the moisture from the fresh meat, forming a hot and humid airflow. This hot and humid airflow is dehumidified by the dehumidifier 12 and then circulates back into the outer cylinder 1.

[0020] Furthermore, a receiving hopper 15 is fixed to the inner feed inlet 7, and the opening of the receiving hopper 15 is fitted against the inner wall of the corresponding sealing cylinder 9. A discharge hopper 16 is installed at the inner discharge outlet 8, and the opening of the discharge hopper 16 is fitted against the inner wall of the corresponding sealing cylinder 9. Mounting grooves are provided around the openings of the receiving hopper 15 and the discharge hopper 16, and ball bearings are installed in the mounting grooves. In this way, the inner cylinder 2 can maintain a sealed connection with the sealing cylinder 9 during rotation, preventing fresh meat from being thrown out from the inner feed inlet 7 and the inner discharge outlet 8 during dehydration. A stirring shaft 17 is installed inside the inner cylinder 2. Both ends of the stirring shaft 17 are rotatably connected to the two ends of the inner cylinder 2. Spiral blades 18 are installed on the stirring shaft 17. The rotation drive mechanism includes a rotary motor 19 and a rotary shaft 20. The rotary motor 19 is mounted on the outer cylinder 1. The rotary shaft 20 rotatably extends into the outer cylinder 1 and connects to the stirring shaft 17. A turntable 21 is fixedly connected to one end of the inner cylinder. The turntable 21 has a slot 22, and a through hole in the middle of the slot 22 allows the stirring shaft 17 to pass through. The inner cylinder 17 is equipped with several evenly spaced semi-circular locking blocks 23. One end of the stirring shaft 17 passes through a through hole and extends into a locking groove 22. Several evenly spaced locking blocks 24 are fixedly connected to the end of the stirring shaft 17 located in the locking groove 22. The locking blocks 24 are mounted on the stirring shaft 17 by springs 27 and are located between adjacent semi-circular locking blocks 23. Each sealing cylinder 9 is equipped with two clamping blocks 31, forming a clamping groove between the two clamping blocks 31 for one side of the receiving hopper 15 or the discharging hopper 16 to engage. When one side of the receiving hopper 15 or the discharging hopper 16 is not engaged in the corresponding locking groove 22, the rotary motor 19 drives the rotary shaft 20 to rotate, thereby driving the stirring shaft 17 to rotate. Because the locking blocks 24 engage between adjacent semi-circular locking blocks 23, the rotation of the stirring shaft 17 drives the turntable 21 to rotate, causing the entire inner cylinder 2 to rotate accordingly. The fresh meat inside the inner cylinder 2 is continuously tumbled, improving dehydration efficiency. After dehydration is complete and feeding is required, the translation drive mechanism moves the sealing cylinder 9, causing one side of the receiving hopper 15 and / or one side of the discharging hopper 16 to engage in the corresponding slot 22, after which the inner cylinder 2 and the sealing cylinder 9 remain relatively stationary. The rotary motor 19 continues to drive the rotating shaft 20 to rotate, and the stirring shaft 17 rotates, using the spiral blades 18 to convey the dehydrated fresh meat in the inner cylinder 2, transporting it to the inner outlet 8 for feeding. To improve control accuracy, an infrared sensor or similar device can be installed inside the outer cylinder 1 to sense the position of the receiving hopper 15, thereby enabling precise positioning control of the inner cylinder 2, etc.

[0021] Furthermore, the translation drive mechanism includes a translation cylinder 25. The outer cylinder 1 has an annular opening 26 for one end of the sealing cylinder 9 to extend movably. After one end of the sealing cylinder 9 extends movably from the outer cylinder 1, it is fixedly connected to the translation cylinder 25. The translation cylinder 25 drives the sealing cylinder 9 to move along a direction parallel to the axis of the outer cylinder 1. To ensure more stable operation of the sealing cylinder 9, a slide rail can be installed inside the outer cylinder 1, with a slider on the slide rail fixedly connected to the sealing cylinder 9. Several slip rings 28 are provided between the inner cylinder 2 and the outer cylinder 1. The slip rings 28 provide support for the inner cylinder 2, maintaining a certain gap between it and the outer cylinder 1 without affecting the rotation of the inner cylinder 2.

[0022] Furthermore, an external exhaust pipe 29 is connected to the exhaust port 10, and valves 30 are respectively installed on the external exhaust pipe 29 and the return pipe 11. By adjusting the valves 30, hot air inside the outer cylinder 1 can be directly exhausted to ensure stable and normal air pressure inside the outer cylinder 1. Alternatively, a fan can be installed directly on the external exhaust pipe 29 to draw away the hot and humid airflow for exhaust, and a heater can be installed inside the outer cylinder 1 to provide a temperature environment of 90-100℃.

[0023] Furthermore, the first conveying mechanism includes a first bucket elevator; the second conveying mechanism includes a second bucket elevator; the third conveying mechanism includes a third bucket elevator; the fourth conveying mechanism includes a first scraper conveyor, a fourth bucket elevator, and a second scraper conveyor connected in sequence, with a second permanent magnet cylinder installed between the second scraper conveyor and the ultrafine grinding chamber 118; the fifth conveying mechanism includes a fifth bucket elevator, a third scraper conveyor, and a sixth bucket elevator in sequence; and the sixth conveying mechanism includes a seventh bucket elevator.

[0024] The low-temperature dehydration process for pet food fresh meat, using the aforementioned low-temperature dehydration system, includes the following steps: Step 1: Crush the fresh meat using crusher 115, then transfer it to low-temperature dehydration device 100 for low-temperature dehydration at 90-99℃, then cool the dehydrated fresh meat using second cooler 106, then separate the meat from the bone, remove the bone, and transfer the fresh meat to dehydrated fresh meat bin 114. Step 2: Different raw materials are released from the batching bin 101 and weighed separately using the batching scale 102. The different raw materials fall into the mixer 103 for mixing and stirring. Step 3: The mixed raw materials are fed into the ultra-fine pulverizer 104 for ultra-fine pulverization, and then loaded into the forming chamber 105 for storage and later use. Step 4: The raw material to be formed in the forming chamber 105 is conveyed to the forming machine 108 for granulation and forming; Step 5: After the pet food is formed, it is transferred to the drying oven 109 to dry, and then transferred to the spraying roller 110 to spray the auxiliary materials. Finally, it is cooled and put into the finished product bin 112 to wait for packaging.

[0025] Furthermore, the molding machine 108 is a baking molding machine or an extruder.

[0026] Furthermore, the dehydrated fresh meat in the dehydrated fresh meat silo 114 has a moisture content of 15-20%, and the pet food in the finished product silo 112 has a moisture content of ≤10%.

[0027] It is worth mentioning that the technical features of baking forming machine, extruder, crusher, bucket elevator, scraper conveyor and other related technologies involved in this patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this patent. This patent will not be further elaborated in detail.

It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
