[0002] In today's pet food industry, manufacturers often apply flavoring or nutritional substances to the surface of pet food in the final stage of pet food processing in order to enhance the nutritional value and appeal of the product. This process aims to provide better taste and additional vitamins, minerals and other essential nutrients to pet food, ensuring that pets can obtain a balanced diet.

[0003] However, different nutrients have their own strict requirements for environmental conditions, especially temperature. Some sensitive nutrients, such as vitamin C and certain active probiotics, may become unstable and easily decompose or lose their effectiveness in high-temperature environments. When these fragile nutrients are sprayed onto pet food that has just been processed at a high temperature, the effective ingredients will quickly be lost, resulting in the actual nutritional content of the final product being much lower than expected.

[0004] However, the existing pet feed production equipment still cannot well solve the above problems, so that the nutritional content of the final pet feed is not as expected. SUMMARY

[0005] The main purpose of the utility model is to provide a pet nutrition feed production device to solve the problem of easy loss of nutritional content in pet food in the prior art.

[0006] To achieve the above purpose, the utility model provides a pet nutrition feed production device, comprising: a first cooling device for receiving and cooling baked and shaped pet feed; a first mixing tank arranged downstream of the first cooling device for receiving pet feed cooled by the first cooling device; a first ingredient spraying device connected to the first mixing tank for first ingredient spraying of pet feed stirred in the first mixing tank; a second cooling device for receiving and cooling pet feed subjected to first ingredient spraying; a first conveying device connected between the second cooling device and the first mixing tank; a second mixing tank arranged downstream of the second cooling device for receiving pet feed cooled by the second cooling device; and a second ingredient spraying device connected to the second mixing tank for second ingredient spraying of pet feed stirred in the second mixing tank.

[0011] Further, the sorting device further comprises a third elevator arranged between the sorting machine and a distributor, and the distributor is arranged between the third elevator and the storage hopper.

[0012] Further, the pet nutrition feed production device further comprises a nutrition bin connected to the second mixing tank through a flow control unit.

[0016] The technical scheme of the utility model is applied to: when the pet feed which has been baked and formed enters the first stirring tank through the first cooling equipment, the temperature of the pet feed has been preliminarily reduced, the granular feed in the pet feed is uniformly mixed with the first nutrient component sprayed by the first component spraying equipment in a more suitable temperature range, and the first conveying equipment is used to convey the pet feed which has been sprayed with the first component from the first stirring tank to the second cooling equipment. Then, the feed which has been sprayed with the first component is reduced in temperature again through the second cooling equipment to further slow down the temperature rise of the surface layer of the feed, and ensure that the mixing in the second stirring tank and the second component spraying process by the second component spraying equipment can be carried out in a more stable temperature environment. Through the cooperative design of the above-mentioned multistage cooling and multiple component spraying, the problem that the nutrient component is decomposed or invalid in the high temperature of the traditional equipment is effectively solved.

[0024] Figure 1 The utility model discloses a pet nutrient feed production device, which comprises a first cooling device 10, a first stirring tank 20, a first component spraying device 30, a second cooling device 40, a first conveying device 50, a second stirring tank 60 and a second component spraying device 70. The first cooling device 10 is used for receiving the baked and shaped pet feed and cooling it. The first stirring tank 20 is arranged downstream of the first cooling device 10 and is used for receiving the pet feed cooled by the first cooling device 10. The first component spraying device 30 is connected to the first stirring tank 20 and is used for spraying the first component on the pet feed stirred in the first stirring tank 20. The second cooling device 40 is used for receiving the pet feed sprayed with the first component and cooling it. The first conveying device 50 is connected between the second cooling device 40 and the first stirring tank 20. The second stirring tank 60 is arranged downstream of the second cooling device 40 and is used for receiving the pet feed cooled by the second cooling device 40. The second component spraying device 70 is connected to the second stirring tank 60 and is used for spraying the second component on the pet feed stirred in the second stirring tank 60.

[0025] Using the technical solution of the present invention, after the baked pet food enters the first mixing tank 20 via the first cooling device 10, its temperature is initially lowered, allowing the granular feed to mix evenly with the first nutrient sprayed by the first ingredient spraying device 30 within a suitable temperature range. The first conveying device 50 is used to transport the pet food, which has been sprayed with the first ingredient, from the first mixing tank 20 to the second cooling device 40. Subsequently, the temperature of the pet food, which has been sprayed with the first ingredient, is further lowered by the second cooling device 40 to further slow the temperature rise of the feed's surface, ensuring that the subsequent mixing in the second mixing tank 60 and the second ingredient spraying by the second ingredient spraying device 70 can proceed under a relatively stable temperature environment. The present invention, through the coordinated design of multi-stage cooling and multiple ingredient spraying, effectively solves the problem of high temperatures causing nutrient decomposition or inactivation in conventional equipment. Under the action of the first cooling device 10 and the second cooling device 40, the pet food receives the nutrients added by the first and second ingredient spraying devices 30 and 70 at suitable temperatures, thereby maintaining the activity and stability of the nutrients. The pet feed obtained in this way is not only richer in sensory perception and flavor, but the actual content of nutrients is closer to the expected value, providing pets with a more comprehensive and balanced nutritional supply.

[0026] As an optional implementation, Figure 1 As shown, in the technical solution of this embodiment, the pet nutritional feed production device also includes a finished product silo 80 and a second conveying device. The finished product silo 80 is arranged downstream of the second mixing tank 60, and the second conveying device is connected between the second mixing tank 60 and the finished product silo 80. The pet feed that has completed the second component spraying and fully mixed in the second mixing tank 60 will be smoothly transported to the finished product silo 80 through the second conveying device. Through the cooperation between the above-mentioned finished product silo 80 and the second conveying device, the present device realizes the efficient collection and stable storage of the final pet feed after the second component spraying and mixing, which helps to avoid secondary pollution and nutritional loss caused by the finished product transportation process, while ensuring that the finished feed enters the finished product silo 80 in a suitable state.

[0027] Preferably, Figure 1As shown, the second conveying equipment includes a first vibrating screen 111, a first elevator 112, and a second elevator 113. The first vibrating screen 111 is used to sort the pet food. The first elevator 112 is connected between the second mixing tank 60 and the first vibrating screen 111, and the second elevator 113 is connected between the first vibrating screen 111 and the finished product silo 80. In use, the combination of the first vibrating screen 111, the first elevator 112, and the second elevator 113 in the second conveying equipment achieves dual optimization of pet food transportation and quality control. The first vibrating screen 111 sorts the pet food from the second mixing tank 60, ensuring more consistent particle size and quality before entering the finished product silo 80. The first elevator 112 and the second elevator 113 respectively transport the pet food upstream and downstream, ensuring efficient material flow from the second mixing tank 60, through the vibrating screen, to the finished product silo 80. This prevents impurities and substandard particle size in the finished product while also ensuring uniform and stable quality of the final feed in the finished product silo 80.

[0028] like Figure 1 As shown, as a preferred embodiment, the pet nutritional feed production apparatus further includes: a packaging device 90, located downstream of the finished product silo 80, for packaging the pet feed in the finished product silo 80. By adding the packaging device 90 downstream of the finished product silo 80, a fully integrated production process is achieved, from raw material processing, spraying, cooling, screening, storage, to final packaging. Pet feed in the finished product silo 80 that has reached the ideal nutritional and quality standards can be directly transported to the packaging device 90 for quantitative packaging and quality assurance, thereby ensuring the high stability and convenience of the final product in the circulation process, effectively reducing secondary contamination and nutritional loss of the finished feed during transfer, while simplifying the subsequent packaging process and improving the integration and production efficiency of the entire pet feed production process.

[0029] Optionally, in the technical solution of this embodiment, the pet nutritional feed production device also includes a dispensing device, which includes a dispenser 114 and a storage hopper 115. Dispenser 114 is located upstream of the first cooling device 10 and selects pet feed that meets the specifications and supplies it to the first cooling device 10. Storage hopper 115 is located downstream of dispenser 114 and is used to receive pet feed that does not meet the specifications selected by dispenser 114. By adding dispensing equipment upstream of the first cooling device 10, and in particular by using dispenser 114 and storage hopper 115 in conjunction with each other, the quality of the pet feed can be controlled. Dispenser 114 pre-selects pet feed that meets the specifications and supplies it to the first cooling device 10, ensuring that the particle size and quality of the material entering the first cooling device 10 are more uniform, thereby improving the overall stability and consistency of the subsequent cooling, mixing, and spraying processes. At the same time, unqualified pet feed is separated and collected by storage hopper 115 for further processing or disposal, reducing waste and unnecessary energy consumption.

[0030] More preferably, in the technical solution of this embodiment, the distributing equipment further includes a third elevator 116 and a distributor 117. Third elevator 116 is positioned between distributor 114 and distributor 117, and distributor 117 is positioned between third elevator 116 and storage hopper 115. By incorporating third elevator 116 and distributor 117 into the distributing equipment, efficient and flexible diversion of unqualified pet food is achieved. Third elevator 116 ensures that unqualified feed screened by distributor 114 is stably and orderly elevated and transported to distributor 117, while distributor 117 further evenly distributes this portion of feed and directs it to storage hopper 115.

[0031] like Figure 1 As shown, as a preferred embodiment, the pet nutritional feed production device also includes a nutrient silo 118, which is connected to the second mixing tank 60 through a flow control unit. By adding the nutrient silo 118 upstream of the second mixing tank 60, a variety of nutrients can be accurately added at the appropriate processing stage. These nutrients are stored in the nutrient silo 118 and can be added evenly and in appropriate amounts through the flow control unit after the pet feed in the second mixing tank 60 is cooled and preliminarily processed, according to actual nutritional needs and formula requirements. This not only better maintains the activity and effectiveness of each nutrient under suitable temperature and stirring conditions, thereby improving the overall nutritional value and palatability of pet food, but also reduces the risk of damage to sensitive ingredients caused by high temperature environments.

[0032] In the technical solution of this embodiment, if Figure 1As shown, the pet nutritional feed production apparatus also includes a first material addition device 119 and a second material addition device 120. The first material addition device 119 is connected to the first mixing tank 20, and the second material addition device 120 is connected to the second mixing tank 60. By placing the first material addition device 119 and the second material addition device 120 upstream of the first mixing tank 20 and the second mixing tank 60, respectively, specific materials can be flexibly and accurately added at different processing stages. The first material addition device 119 ensures that the required nutrients or supplementary ingredients are added to the pet feed after initial cooling by the first cooling device 10, thereby improving the overall uniformity of the initial ingredient spraying and mixing. The second material addition device 120 can add more refined nutritional or functional ingredients after the pet feed is further cooled by the second cooling device 40 and meets suitable environmental conditions, thereby achieving a higher level of nutritional balance and quality assurance in the second mixing tank 60. This segmented and targeted addition strategy can more effectively maintain the activity of nutrients, reduce waste and loss, and ultimately produce a nutritionally comprehensive pet food product with a stable taste.

[0033] More preferably, a first dust collector 121 is provided at the first material adding device 119, and a second dust collector 122 is provided at the second material adding device 120. By respectively providing the first dust collector 121 and the second dust collector 122 at the first material adding device 119 and the second material adding device 120, the dust pollution problem in the process of adding powdered materials can be effectively reduced. When a large amount of fine dust is generated in the process of unpacking the powder and putting it into the first material adding device 119, the first dust collector 121 can capture and filter it in time to ensure that the relevant equipment is not affected by the dust. Similarly, the second dust collector 122 purifies the dust at the second material adding device 120, which is conducive to maintaining a good processing environment in the second mixing tank 60. In this way, not only the cleanliness of the production site and the work safety of the operators are improved, but also stable and dust-free conditions are provided for the operation of the entire process including the first cooling equipment 10 and the second cooling equipment 40.

The second component spraying device 70 comprises a second oil tank 71 and a second flow control unit 72, and the second oil tank is connected to the second stirring tank 60 through the second flow control unit 72. By respectively providing the first oil tank 31 and the second oil tank 71 in the first component spraying device 30 and the second component spraying device 70 and their corresponding first flow control unit 32 and second flow control unit 72, the addition amount and timing of the nutritional oil or flavor liquid can be accurately controlled. Before spraying in the first stirring tank 20 and the second stirring tank 60, the spraying rate and spraying amount can be flexibly adjusted through the flow control unit according to the formula requirements of the pet food and the actual working conditions such as temperature and humidity, so as to ensure that the surface of the feed particles is uniformly coated with the predetermined component, which is beneficial to improve the palatability and stability of the finished feed.

[0035] Preferably, in the technical scheme of the embodiment, the first cooling device 10 comprises a cooling bin 11, a fan 12, a shaker 13 and a damper 14, the cooling bin 11 is used to receive pet feed, the fan 12 blows air to the cooling bin 11 through the shaker 13, and the damper 14 is arranged downstream of the shaker 13. After the pet feed enters the cooling bin 11, the fan 12 blows air into it through the shaker 13, thereby forming effective forced convection to achieve rapid cooling. The shaker 13 can separate and capture fine dust or particles in the air during this process, ensuring the cleanliness and safety of the downstream pipeline and equipment. The damper 14 builds a sealed barrier between the material conveying and the cooling air environment, preventing excessive exchange of cooling air with the external environment, thereby maintaining stable internal cooling conditions. Similarly, the structure of the second cooling device 40 is the same as that of the first cooling device 10.

[0036] More preferably, in the technical scheme of the embodiment, a first collecting hopper 123 is further arranged downstream of the first cooling device 10, the first collecting hopper 123 is used for receiving the pet feed cooled by the first cooling device 10, a first material scale 124 and a first weighing gate 125 are further arranged downstream of the first collecting hopper 123, the first material scale 124 and the first weighing gate 125 are used for controlling the flow of the pet feed delivered by the first collecting hopper 123 to the first stirring tank 20.

By adding the first collecting hopper 123, the first material scale 124 and the first weighing gate 125 downstream of the first cooling device 10, the quantitative and continuous control of the cooled pet feed is realized. The first collecting hopper 123 can timely collect the pet feed cooled by the first cooling device 10, and the first material scale 124 and the first weighing gate 125 can accurately adjust the material flow according to the production demand, so as to provide stable and controllable raw material input for the stirring and spraying operation in the first stirring tank 20. At the same time, the second collecting hopper 126 arranged downstream of the first stirring tank 20 is used for receiving the pet feed sprayed with the first component, which helps to maintain uniform material supply in the subsequent process.

[0037] Similarly, a third collecting hopper 127 is further arranged downstream of the second cooling device 40, the third collecting hopper 127 is used for receiving the pet feed cooled by the second cooling device 40, a second material scale 128 and a second weighing gate 129 are further arranged downstream of the third collecting hopper 127, the second material scale 128 and the second weighing gate 129 are used for controlling the flow of the pet feed delivered by the third collecting hopper 127 to the downstream.

By adding the third collecting hopper 127, the second material scale 128 and the second weighing gate 129 downstream of the second cooling device 40, the delivery amount of the cooled pet feed can be accurately controlled, so that the downstream link always obtains suitable and stable material supply. The third collecting hopper 127 centrally receives the pet feed cooled by the second cooling device 40, and the second material scale 128 and the second weighing gate 129 accurately control the output amount of the pet feed according to the production demand, so as to ensure that the subsequent processes, such as the second stirring tank 60 and the fourth collecting hopper 130 arranged downstream thereof, spray and mix the components under the best working condition.

[0038] In the technical scheme of the embodiment, the flow material control unit comprises a third material scale 131 and a third weighing hopper door 132. The third material scale 131 and the third weighing hopper door 132 are key components in the flow material control unit, and are used to realize accurate regulation of the feeding process of the nutrient material bin 118 to the second stirring tank 60. The third material scale 131 can accurately weigh and measure the nutrient material, so as to ensure that the nutrient ingredients added in the second stirring tank 60 are consistent with the predetermined formula. The third weighing hopper door 132 adjusts the inflow rate of the nutrient material according to the value fed back by the third material scale 131, so as to realize accurate control of the amount of material added.

[0039] Preferably, in the technical scheme of the embodiment, the first conveying device 50 is connected with the second cooling device 40 through the second vibrating screen 51. The first conveying device 50 is connected with the second cooling device 40 through the second vibrating screen 51, thereby realizing accurate screening and efficient transmission of the material.
