Description

Technical Field

[0001] This utility model relates to the field of pet food processing technology, and in particular to a pet food oil homogenization emulsification spraying device. Background Technology

[0002] In current pet food production and processing, extruded dry pet food typically undergoes a series of processes including drying, adding oil, adding liquid flavoring agents, and adding solid flavoring agents. Current processes usually involve directly mixing the oil onto the surface of the dried food or using vacuum extraction to inject the oil into the pores of the extruded food. However, both methods have several drawbacks. For example, after a period of storage, the oil is prone to seeping out, leading to easy oxidation of the food. Furthermore, pets generally have a low rate of oil digestibility and absorption in pet food, affecting the sensory experience during shelf life and failing to meet the high digestibility and absorption requirements of pets for oils.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0023] Please see Figure 1 This utility model provides a pet food oil homogenization emulsification spraying equipment, including a homogenization emulsification device 1 and a vacuum spraying device 2; an oil storage tank 3, an emulsifier tank 4 and a water supply pipe 5 are provided upstream of the homogenization emulsification device 1; the homogenization emulsification device 1 includes a first tank body 11, a first stirring mechanism 12 disposed in the first tank body 11 and an emulsification pump 13; the discharge port of the first tank body 11 is connected to the inlet of the vacuum spraying device 2.

[0024] In practical use, oil, emulsifier, and water are first added to the first tank 11 according to the formula ratio. Then, the first stirring mechanism 12 is started to mix thoroughly. After thorough mixing, the first stirring mechanism 12 is turned off, and the emulsification pump 13 is started to homogenize the mixture in the first tank 11 under high pressure to form a stable emulsion. Specifically, the inlet and outlet of the emulsification pump 13 are both located inside the first tank 11, and it circulates and draws in the solution during operation. The emulsion is then transported to the vacuum spraying device 2 for spraying. Before spraying, puffed dry food is added to the vacuum spraying device 2, and a vacuum treatment is performed in advance. After the emulsion is sprayed, the oil in the emulsion state can be better absorbed into the interior by the puffed dry food, and the mixture is more uniform and more stable, making it less likely to overflow during subsequent storage.

[0025] Preferably, the first stirring mechanism 12 is driven by a variable frequency motor.

[0026] Please see Figure 1 In one embodiment, a weighing device 31 is provided between the oil storage tank 3 and the homogenizing emulsification device 1, and a first delivery pump 32 is provided between the weighing device 31 and the homogenizing emulsification device 1. Specifically, the pet food oil homogenizing emulsification spraying equipment also includes a control device, and the weighing device 31 is electrically connected to the control device. Before homogenizing emulsification, the amount of oil added can be accurately controlled by the weighing device 31. The first delivery pump 32 is electrically connected to the control device. When the weighing weight of the weighing device 31 reaches the set value, the first delivery pump 32 starts and delivers the oil into the first tank 11.

[0027] Please see Figure 1 In one embodiment, a first flow meter 41 and a second delivery pump 42 are provided between the emulsifier tank 4 and the homogenizing emulsification device 1. The second delivery pump 42 is located upstream of the first flow meter 41, and the first flow meter 41 and the second delivery pump 42 are electrically connected to a control device. When the first flow meter 41 detects that the amount of emulsifier added is sufficient, the control device stops the second delivery pump 42 from operating.

[0028] Specifically, the amount of water added can be controlled using a flow meter and a water pump. The water supply pipe can be connected to a water tank.

[0029] Please see Figure 1 In one embodiment, the emulsifying pump 13 is disposed at the bottom of the first tank 11 and below the first stirring mechanism 12. Specifically, the inlet of the emulsifying pump 13 is located at the bottom, and the outlet of the emulsifying pump 13 is located at the top. By continuously circulating and drawing in the mixture within the first tank 11, the oil is sufficiently homogenized and emulsified.

[0030] Please see Figure 1In one embodiment, the homogenizing emulsification device 1 further includes a steam generator 14 and a jacket 15 disposed on the outer shell of the first tank 11, wherein the steam generator 14 and the jacket 15 are connected by a pipe. The steam generator 14 is used to provide high-temperature steam to the jacket 15, and the jacket 15 then transfers heat to the first tank 11. By raising the temperature of the oil, the dispersion effect of the oil can be improved, and it can help to form an emulsion with smaller particles.

[0031] Please see Figure 1 In one embodiment, a temperature sensor 16 is installed inside the first tank 11. The temperature sensor 16 is used to detect the temperature inside the first tank 11 in real time. When the temperature is too high, it triggers the steam generator 14 to stop the continued supply of high-temperature steam.

[0032] Please see Figure 1 In one embodiment, the homogenizing emulsification device 1 further includes a support frame 18, on which a weight sensor 17 is mounted, and the first tank 11 is mounted on the weight sensor 17. Specifically, the weight sensor 17 is electrically connected to a control device and is used to detect changes in the weight of the first tank 11. During spraying, it is also necessary to precisely control the amount of emulsion sprayed. By detecting the overall weight change of the first tank 11, the amount of emulsion sprayed can be reflected.

[0033] Please see Figure 2 In one embodiment, the vacuum spraying device 2 includes a second tank 21, a vacuum pumping device 24, and a second stirring mechanism 22 disposed within the second tank 21. The vacuum pumping device 24 is connected to the top of the second tank 21. Multiple first nozzles 23 are disposed within the second tank 21, and the inlets of the first nozzles 23 are connected to the outlets of the first tank 11. Specifically, the top of the second tank 21 is provided with an extruded dry food inlet. Before spraying the emulsion, a specific weight of extruded dry food is added to the second tank 21, then the extruded dry food inlet is closed, and the vacuum pumping device 24 is activated. Once the vacuum level within the second tank 21 reaches the required level, the emulsion is sprayed out through the first nozzles 23. During the spraying of the emulsion, the second stirring mechanism 22 operates, continuously stirring the extruded dry food during the spraying process to ensure that the emulsion is evenly sprayed onto the extruded dry food.

[0034] Please see Figure 2 In one embodiment, a plurality of first nozzles 23 are disposed on the top of the second tank 21; each first nozzle 23 is provided with a spraying arm 231, which is used to rotate the first nozzle 23. Specifically, the first nozzle 23 is provided with a plurality of nozzles. The spraying arm 231 allows the spraying direction of the nozzles to be changed during the spraying process, and combined with the continuously stirring second stirring mechanism 22, the puffed dry food can be sprayed with emulsion more evenly.

[0035] Please see Figure 3 In one embodiment, the second tank 21 is equipped with a plurality of second nozzles 25, which are connected to the liquid flavoring agent tank 6 via a liquid flavoring agent pipeline 61. The liquid flavoring agent pipeline 61 is equipped with a second flow meter 62 and a third delivery pump 63. The liquid flavoring agent tank 6 is used to store the liquid flavoring agent. The third delivery pump 63 is located upstream of the second flow meter 62. The second flow meter 62 and the third delivery pump 63 are electrically connected to a control device. In this embodiment, after the emulsion is sprayed, the liquid flavoring agent is further sprayed to improve the palatability of the puffed dry food.

[0036] In summary, this utility model, by sequentially setting up a homogenizing emulsification device 1 and a vacuum spraying device 2, uses an integrated device to homogenize and emulsify the oil, and then sprays the resulting emulsion onto the puffed dry food, thereby effectively allowing the oil to better penetrate into the puffed dry food and better bind with it, reducing overflow and oxidation problems.

[0037] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
