Abstract
Description
Technical Field
[0001] This utility model relates to the field of dairy processing technology, specifically a dairy product sterilization device for processing. Background Technology
[0002] Dairy products are various foods made from raw milk and its products. Raw milk may carry a variety of pathogens, which can cause serious food poisoning or infectious diseases. Therefore, sterilization is a crucial step in the processing of dairy products. Sterilization can effectively kill these pathogens and reduce food safety risks.
[0003] Existing sterilization equipment for dairy processing mainly consists of a tank, a stirring mechanism, and a heating element. When sterilizing dairy products, the dairy products to be processed are fed into the tank through a hopper. Then, the heating element heats the dairy products in the tank. At the same time, the motor is started to rotate the stirring rod, which stirs the dairy products and creates a dynamic flow within the tank. This breaks the problem of local overheating or temperature gradients caused by traditional static heating, ensuring that heat is evenly transferred to every part and further improving the effect of high-temperature sterilization.
[0004] Existing sterilization devices for dairy processing result in rapid temperature rise and drying of dairy products near the heating elements on the outside, while the inner dairy products primarily receive heat through conduction, leading to lower heat transfer efficiency and slower drying. Furthermore, a temperature gradient exists within the tank, with higher temperatures near the heating elements and lower temperatures further away, hindering uniform heating of the dairy products. Moreover, existing sterilization devices rely solely on stirring, which fails to adequately agitate the dairy products for even heating, thus impacting sterilization effectiveness. Therefore, this paper proposes a new sterilization device for dairy processing to address these issues. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a sterilization device for dairy products in processing.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A dairy product sterilization device for processing, comprising a tank, an annular groove inside the tank, multiple heating tubes arranged within the annular groove, a hollow rotating shaft rotatably mounted inside the tank, multiple hollow stirring rods connected to the circumference of the hollow rotating shaft, a guide pipe connected to the annular groove, and the other end of the guide pipe rotatably connected to the top port of the hollow rotating shaft, an exhaust fan connected to the guide pipe, a support base fixedly connected between the bottom side of the exhaust fan housing and the tank, and an outer surface of the tank being fitted with... The device has a control panel for starting and stopping the heating element, motor, and exhaust fan. When sterilizing dairy products, the heating element heats the dairy products inside the tank, while the exhaust fan is activated to allow high-temperature gas from the annular groove to flow into the hollow rotating shaft through the guide pipe, and then into the hollow stirring rod. This facilitates heating of the dairy products inside the tank, creating a dual heating path that heats the dairy products from both the outside and inside. This reduces intermediate heat transfer steps, avoids localized overheating or temperature gradients, and ensures uniform temperature distribution within the tank, thereby improving sterilization effect and efficiency.
[0007] Preferably, two support rods are fixed at the top and bottom of the circumferential surface of the hollow rotating shaft. Two support rods on the same side are rotatably mounted on rotating rods. Multiple second stirring rods are fixed on each rotating rod, and the hollow stirring rods and second stirring rods are staggered. A scraper is fixed to the end of each second stirring rod. A first gear is fitted onto the top of each of the two rotating rods. A gear ring is fixed to the inner wall of the tank, and the gear ring meshes with the first gear. A protective cover is installed on the top side of the tank, and a motor is installed on the top side of the protective cover. An active motor is installed at the output end of the motor. The hollow shaft has a driven gear mounted on its top end, and the driving gear meshes with the driven gear. When heating and sterilizing dairy products, the rotation of the hollow stirring rod and the rotation and self-rotation of the second stirring rod create a compound stirring method that allows the dairy products to be fully stirred and mixed in the tank, avoiding dead corners and ensuring that all parts of the dairy products are heated evenly, further improving the sterilization effect. Through the synergistic effect of dual heating and compound stirring, the dairy products are ensured to be heated evenly, ensuring that all microorganisms are effectively killed, greatly improving the sterilization effect and efficiency.
[0008] Preferably, a partition is fixed to the inner wall of the tank, a disc is fitted at the top of the hollow rotating shaft, and an annular channel is formed between the disc and the partition. The rotating rod passes through the annular channel. When stirring the dairy products, the annular channel is provided to avoid obstruction of the rotating rod during rotation and to provide a clear movement trajectory for the rotating rod.
[0009] Preferably, a feeding hopper is connected to the top of the circumferential surface of the tank, a discharge pipe is connected to the bottom of the tank, a one-way valve is installed on the discharge pipe, and an air outlet pipe is connected to the tank. When using this device, the feeding hopper facilitates the addition of materials into the tank, the discharge pipe facilitates the discharge of processed dairy products, and the air outlet pipe can discharge excess gas, maintaining the pressure inside the tank within a safe range and ensuring the stable operation of the entire sterilization process.
[0010] Preferably, three support columns are fixed to the bottom of the tank, and an anti-slip pad is fixed to the bottom of each support column. When using the device, the anti-slip pad can increase the friction between the support column and the ground, making the support column more stable in supporting the tank and further improving the overall stability of the device.
[0011] The advantages of this utility model are:
[0012] 1. In the sterilization of dairy products, this utility model heats the dairy products inside the tank through a heating tube, while simultaneously activating an exhaust fan to allow high-temperature gas in the annular groove to flow into the hollow rotating shaft through a guide pipe, and then into the hollow stirring rod. This facilitates the heating of the dairy products inside the tank, thus forming a dual heating path. This allows the dairy products to be heated from both the outside and the inside, reducing intermediate heat transfer links, avoiding local overheating or temperature gradients, and ensuring uniform temperature distribution inside the tank, thereby improving the sterilization effect and efficiency.
[0013] 2. When heating and sterilizing dairy products, this utility model utilizes the rotation of the hollow stirring rod and the rotation and self-rotation of the second stirring rod. This composite stirring method ensures that the dairy products are fully mixed in the tank, avoiding dead corners and ensuring that all parts of the dairy products are heated evenly, further improving the sterilization effect. Through the synergistic effect of dual heating and composite stirring, the dairy products are ensured to be heated evenly, ensuring that all microorganisms are effectively killed, greatly improving the sterilization effect and efficiency.

[0022] Please see Figure 1-5As shown, a dairy product sterilization device for processing includes a tank 1. An annular groove 2 is formed inside the tank 1, and multiple heating tubes 3 are arranged within the annular groove 2. A partition 4 is fixedly connected to the inner wall of the tank 1. A hollow rotating shaft 5 is rotatably mounted inside the tank 1, and multiple hollow stirring rods 8 are connected to the circumference of the hollow rotating shaft 5. A guide pipe 19 is connected to the annular groove 2, and the other end of the guide pipe 19 is rotatably connected to the top port of the hollow rotating shaft 5. An exhaust fan 21 is connected to the guide pipe 19. A support base 20 is fixedly connected between the bottom side of the exhaust fan 21 housing and the tank 1. A control panel 25 is installed on the outer surface of the tank 1, and the control panel 25 is used to control the start and stop of the heating tubes 3, the motor 17, and the exhaust fan 21. The top of the rotating shaft 5 is fitted with a disc 6, and an annular channel 7 is formed between the disc 6 and the partition 4. During operation, when sterilizing dairy products, the dairy products to be processed are first fed into the tank 1 through the feed hopper 22. Then, the dairy products in the tank 1 are heated through the heating tube 3. At the same time, the exhaust fan 21 is started so that the high-temperature gas in the annular groove 2 flows into the hollow rotating shaft 5 through the guide pipe 19, and then flows into the hollow stirring rod 8, which facilitates the heating of the dairy products inside the tank 1. This forms a dual heating path, so that the dairy products are heated from the outside and the inside at the same time, reducing the intermediate links of heat transfer, avoiding local overheating or temperature gradients, and ensuring uniform temperature distribution inside the tank 1, thereby improving the sterilization effect and efficiency.
[0023] Two support rods 9 are fixed at the top and bottom of the circumferential surface of the hollow rotating shaft 5. Two support rods 9 on the same side are fitted with rotating rods 10, which pass through the annular channel 7. Multiple second stirring rods 11 are fixed to each rotating rod 10, and the hollow stirring rods 8 and second stirring rods 11 are staggered. A scraper 12 is fixed to the end of each second stirring rod 11. A first gear 13 is fitted onto the top of each of the two rotating rods 10. A gear ring 14 is fixed to the inner wall of the tank body 1, and the gear ring 14 meshes with the first gear 13. A protective cover 16 is installed on the top side of the tank body 1, and a motor 17 is installed on the top side of the protective cover 16. A drive gear 18 is installed at the output end of the motor 17. A driven gear 15 is fitted onto the top of the hollow rotating shaft 5, and the drive gear 18 meshes with the driven gear 15. During operation, while heating and sterilizing the dairy products, the motor 17 is started, causing the drive gear 18 to... The rotation forces the driven gear 15 to drive the hollow shaft 5 to rotate. The hollow shaft 5 drives the hollow stirring rod 8 and the support rod 9 to rotate. The support rod 9 drives the rotating rod 10, the second stirring rod 11, and the scraper 12 to rotate. With the cooperation of the first gear 13 and the gear ring 14, the rotating rod 10 rotates and rotates on its own axis, thereby causing the second stirring rod 11 to rotate on its own axis and rotate. Through the rotation of the hollow stirring rod 8 and the rotation and rotation of the second stirring rod 11, this compound stirring method can make the dairy products fully mixed in the tank 1, avoid dead corners, and ensure that all parts of the dairy products are heated evenly, further improving the sterilization effect. At the same time, the scraper 12 can scrape off the dairy product residue on the inner wall of the tank 1 to prevent scaling. Through the synergistic effect of dual heating and compound stirring, the dairy products can be heated evenly, ensuring that all microorganisms can be effectively killed, greatly improving the sterilization effect and efficiency.
[0024] Please see Figure 1-2 As shown, a feeding hopper 22 is connected to the top of the circumferential surface of the tank 1, and a discharge pipe 23 is connected to the bottom of the tank 1.

[0025] Three support columns 26 are fixed to the bottom of the tank body 1, and each support column 26 is fixed to the bottom end with an anti-slip pad 27. When the device is in operation, by setting the anti-slip pad 27, the friction between the support column 26 and the ground can be increased, so that the support column 26 can more stably support the tank body 1, and further improve the overall stability of the device.
[0026] Working Principle: Existing sterilization devices for dairy processing result in the following issues: Dairy products near the heating element 3 experience rapid temperature increases and faster drying during sterilization, while the inner products primarily receive heat through conduction, leading to lower efficiency and slower drying. A temperature gradient exists within the tank 1, with higher temperatures near the heating element 3 and lower temperatures further away, hindering uniform heating of the dairy products. Furthermore, existing sterilization devices rely solely on stirring, which fails to adequately agitate the dairy products for even heating, thus impacting sterilization effectiveness. Therefore, a new method is proposed to address these problems. A dairy product sterilization device for processing: When sterilizing dairy products, the dairy products to be processed are first fed into the tank 1 through the feed hopper 22. Then, the dairy products in the tank 1 are heated through the heating pipe 3. At the same time, the exhaust fan 21 is started so that the high-temperature gas in the annular groove 2 flows into the hollow rotating shaft 5 through the guide pipe 19, and then into the hollow stirring rod 8, which facilitates the heating of the dairy products inside the tank 1. This forms a dual heating path, so that the dairy products are heated from the outside and the inside at the same time, reducing the intermediate links of heat transfer, avoiding local overheating or temperature gradients, and ensuring uniform temperature distribution inside the tank 1, thereby improving the sterilization effect and efficiency.
[0027] While heating and sterilizing dairy products, the motor 17 is started, causing the drive gear 18 to rotate. This forces the driven gear 15 to drive the hollow shaft 5 to rotate. The hollow shaft 5 drives the hollow stirring rod 8 and the support rod 9 to rotate. The support rod 9 drives the rotating rod 10, the second stirring rod 11, and the scraper 12 to rotate. With the cooperation of the first gear 13 and the gear ring 14, the rotating rod 10 rotates and also rotates on its own axis, causing the second stirring rod 11 to rotate on its own axis and rotate. Through the rotation of the hollow stirring rod 8 and the rotation and rotation of the second stirring rod 11, this compound stirring method can ensure that the dairy products are fully stirred and mixed in the tank 1, avoiding dead corners and ensuring that all parts of the dairy products are heated evenly, further improving the sterilization effect. At the same time, the scraper 12 can scrape off the dairy product residue on the inner wall of the tank 1 to prevent scaling. Through the synergistic effect of dual heating and compound stirring, the dairy products can be heated evenly, ensuring that all microorganisms are effectively killed, greatly improving the sterilization effect and efficiency.
