Description

Technical Field

[0001] This utility model relates to the field of sterilization technology, and more specifically, to a sterilization device for dairy product processing. Background Technology

[0002] In existing technologies, sterilization devices for dairy processing generally suffer from problems such as poor continuous sterilization effect and inconvenient steam feed rate adjustment. These problems directly affect the production efficiency, quality and safety of dairy products.

[0003] Firstly, the poor effectiveness of continuous sterilization stems from the fact that traditional sterilization devices typically employ fixed heating methods or temperature control systems. This approach often struggles to ensure temperature uniformity at every stage of the sterilization process. Dairy products require stable and sufficient temperatures during sterilization to kill any potentially harmful bacteria or pathogens. However, existing devices cannot precisely control the heating effect in different areas, resulting in temperatures in some areas failing to meet sterilization standards, thus affecting the sterilization outcome. Uneven sterilization may leave bacteria in dairy products, impacting their taste, quality, and even food safety.

[0004] Furthermore, the inconvenience of adjusting the steam feed rate in existing sterilization equipment is also a significant factor affecting dairy processing. Steam is a crucial heat source in dairy sterilization, and its temperature, pressure, and flow rate directly impact the sterilization effect. However, many current equipment systems employ fixed flow rate and pressure designs for their steam supply systems, making it difficult to adjust the steam feed rate according to different process requirements or production batches. When the type of dairy products produced or the processing volume changes, a fixed steam feed rate may not meet the required temperature and pressure conditions, resulting in unsatisfactory sterilization. For example, excessive steam feed may lead to excessively high temperatures, damaging the nutritional components or flavor of the dairy products; insufficient steam feed may prevent the required sterilization temperature from being reached, affecting the sterilization effect.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a sterilization device for dairy product processing, which has the following beneficial effects:

[0018] This invention features a circulating sterilization mechanism. Through the combination of a circulating pump and a steam pump, dairy products circulate from the bottom and top via two sets of circulation pipes during the sterilization process.

[0030] Please see Figures 1-5A sterilization device for dairy product processing includes a sterilization tank 1, a circulating sterilization mechanism, a steam regulating mechanism, and a regulating auxiliary mechanism. The circulating sterilization mechanism includes a circulating pump 2 and a steam pump 3. Circulating pipes 4 are installed at both ends of the circulating pump 2. Two sets of circulating pipes 4 extend into the bottom end and top side of the sterilization tank 1, respectively. An air inlet pipe 5 is provided through the side wall of the sterilization tank 1. One end of the steam pump 3 is connected to the air inlet pipe 5 through the steam regulating mechanism. The steam regulating mechanism includes a regulating pipe 6 and rotating blocks 7. A rotating sleeve 8 is rotatably installed on the outer wall of the regulating pipe 6, and a top guide groove 9 is opened on the rotating sleeve 8. Multiple sets of rotating blocks 7 are rotatably installed in the side wall of the regulating pipe 6. A top guide block 10 is installed on the top end of the rotating block 7, and the top guide block 10 is slidably guided in the top guide groove 9. The rotation of the rotating sleeve 8 drives the multiple sets of rotating blocks 7 to rotate, and the rotating blocks 7 are rotatably contacted with each other.

[0031] In this embodiment, sterilization is achieved through the coordinated operation of the circulation pump 2 and the steam pump 3. The circulation pipes 4 at both ends of the circulation pump 2 extend into the bottom and top sides of the sterilization tank 1, respectively, forming a circulation loop. After the circulation pump 2 is started, the dairy products in the sterilization tank 1 are drawn out from the bottom, transported through the circulation pipes 4 to the top for re-injection, forming a continuous circulation flow. At the same time, the steam pump 3 supplies steam to the air inlet pipe 5 of the sterilization tank 1 through the steam regulating mechanism, providing the high-temperature environment required for sterilization. The stirring blade assembly 15 inside the sterilization tank 1 is driven to rotate by an external stirring motor to ensure that the dairy products are fully mixed during the circulation process, achieving uniform sterilization. The steam flow rate is precisely controlled by the cooperation of the regulating pipe 6 and the rotating block 7. The rotating sleeve 8 on the outer wall of the regulating pipe 6 is installed to limit rotation. The sleeve is provided with a top guide groove 9. Multiple sets of rotating blocks 7 are rotatably installed inside the side wall of the regulating pipe 6. The top guide block 10 at the top slides and is guided in the top guide groove 9, and the bottom guide block 21 at the bottom slides and is guided in the bottom guide groove 20 inside the regulating pipe 6. When the rotating sleeve 8 rotates, it drives multiple sets of rotating blocks 7 to rotate synchronously through the top guide groove 9. The contact setting between the rotating blocks 7 enables them to work in coordination and adjust the opening of the steam channel, thereby precisely controlling the steam flow rate and pressure entering the sterilization tank 1.

[0032] The adjustment auxiliary mechanism includes a bottom rotating block 11 and a tightening block 12. An outer fixing plate 13 is fixedly installed on the outer wall of the clamping tube. A tightening block 12 is slidably installed on the outer fixing plate 13. Multiple sets of tightening blocks 12 are provided. A tightening spring 14 is installed between adjacent tightening blocks 12. Multiple sets of bottom rotating blocks 11 are installed at the bottom end of the rotating sleeve 8. The bottom rotating blocks 11 pass through different tightening blocks 12 in sequence, so that the rotating sleeve 8 rotates stably on the adjustment tube 6.

[0033] In this embodiment, to ensure the stable operation of the steam regulating mechanism, multiple sets of tightening blocks 12 are slidably mounted on the outer fixed plate 13. The tightening springs 14 between adjacent tightening blocks 12 provide preload. Multiple sets of bottom rotating blocks 11 at the bottom of the rotating sleeve 8 pass sequentially between different tightening blocks 12, forming a stable support and guiding system. When the rotating sleeve 8 rotates, the bottom rotating blocks 11 move smoothly under the constraint of the tightening blocks 12. The elastic effect of the tightening springs 14 eliminates gaps and vibrations during the rotation process, ensuring that the rotating sleeve 8 rotates stably on the regulating pipe 6, thereby improving the accuracy and reliability of steam regulation.

[0034] Please see Figures 1-5 As a supplementary embodiment of a sterilization device for dairy processing, which includes a circulating sterilization mechanism, a steam regulating mechanism, and a regulating auxiliary mechanism: A stirring blade assembly 15 is rotatably mounted on the internal support of the sterilization tank 1. One end of the stirring blade assembly 15 is connected to an external stirring motor. A side frame 16 is mounted on the side of the sterilization tank 1, and a steam pump 3 is mounted on the top end of the side frame 16. A side pipe 17 is mounted on the side of the steam pump 3, and one end of the rotating sleeve 8 is sealed and rotated in conjunction with the side pipe 17. A connecting pipe 18 is mounted on one end of the steam pump 3 and is connected to an external air supply device through the connecting pipe 18. A main frame 19 is mounted on the side of the sterilization tank 1, and the bottom end of the main frame 19 is in contact with the opposite side. A bottom guide groove 20 is opened in the side wall of the regulating pipe 6, and a bottom guide block 21 is mounted on the bottom end of the rotating block 7. The bottom guide block 21 is slidably guided in the bottom guide groove 20.

[0035] More specifically, the dairy products requiring sterilization are injected into sterilization tank 1. An external stirring motor is started, and the stirring blade assembly 15 begins to rotate. Steam pump 3 obtains steam from an external air supply device via connecting pipe 18 and is sealed to the rotating sleeve 8 via side pipe 17. According to the sterilization process requirements, the rotating sleeve 8 of the steam regulating mechanism is rotated to adjust the opening of multiple sets of rotating blocks 7, controlling the steam flow rate and temperature entering sterilization tank 1. Circulation pump 2 starts, extracting the dairy products from the bottom of sterilization tank 1 and transporting them to the top for re-injection through circulation pipe 4, forming a continuous cycle. Simultaneously, steam enters sterilization tank 1 through air inlet pipe 5, providing the high-temperature environment required for sterilization. The stirring blade assembly 15 continues to rotate, ensuring thorough mixing of the dairy products in the high-temperature steam environment for uniform sterilization. The steam flow rate is precisely controlled by adjusting the stabilizing effect of the auxiliary mechanism, maintaining a constant temperature within sterilization tank 1. After the predetermined sterilization time is reached, the steam supply is shut off, circulation pump 2 is stopped, and the sterilized dairy products can then undergo further processing.

[0036] In summary, during the use or operation of the overall equipment: when the circulating sterilization mechanism is in operation, sterilization is achieved through the coordinated work of the circulating pump 2 and the steam pump 3. The circulating pipes 4 at both ends of the circulating pump 2 extend into the bottom and top sides of the sterilization tank 1, respectively, forming a circulation loop. After the circulating pump 2 is started, the dairy products in the sterilization tank 1 are drawn out from the bottom and transported to the top for re-injection through the circulating pipes 4, forming a continuous circulation flow. At the same time, the steam pump 3 delivers steam to the air inlet pipe 5 of the sterilization tank 1 through the steam regulating mechanism, providing the high-temperature environment required for sterilization. The stirring blade assembly 15 in the sterilization tank 1 is driven to rotate by an external stirring motor to ensure that the dairy products are fully mixed during the circulation process, achieving uniform sterilization. When the steam regulating mechanism is in operation, the steam flow rate is precisely controlled by the cooperation of the regulating pipe 6 and the rotating block 7. The rotating sleeve 8 on the outer wall of the regulating pipe 6 is installed in a limited rotation position. The sleeve is provided with a top guide groove 9. Multiple sets of rotating blocks 7 are rotatably installed inside the side wall of the regulating pipe 6. The top guide block 10 at the top slides and is guided in the top guide groove 9, and the bottom guide block 21 at the bottom slides and is guided in the bottom guide groove 20 inside the regulating pipe 6. When the rotating sleeve 8 rotates, it drives multiple sets of rotating blocks 7 to rotate synchronously through the top guide groove 9. The contact setting between the rotating blocks 7 enables them to work in coordination and adjust the opening of the steam channel, thereby precisely controlling the steam flow rate and pressure entering the sterilization tank 1. When the auxiliary mechanism needs to be adjusted, to ensure the stable operation of the steam regulating mechanism, multiple sets of tightening blocks 12 are slidably mounted on the outer fixed plate 13. The tightening springs 14 between adjacent tightening blocks 12 provide pre-tightening force. Multiple sets of bottom rotating blocks 11 at the bottom of the rotating sleeve 8 pass through the different tightening blocks 12 in sequence, forming a stable support and guiding system. When the rotating sleeve 8 rotates, the bottom rotating blocks 11 move smoothly under the constraint of the tightening blocks 12. The elastic effect of the tightening springs 14 eliminates the gaps and vibrations during the rotation process, ensuring that the rotating sleeve 8 rotates stably on the regulating pipe 6, thereby improving the accuracy and reliability of steam regulation.

[0037] The dairy products requiring sterilization are injected into sterilization tank 1. The external stirring motor is started, and the stirring blade assembly 15 begins to rotate. Steam pump 3 obtains steam from an external air supply device through connecting pipe 18 and is sealed to the rotating sleeve 8 through side pipe 17. According to the sterilization process requirements, the rotating sleeve 8 of the steam regulating mechanism is rotated to adjust the opening of multiple sets of rotating blocks 7, controlling the steam flow rate and temperature entering sterilization tank 1. Circulation pump 2 is started, drawing out the dairy products from the bottom of sterilization tank 1 and transporting them to the top for re-injection through circulation pipe 4, forming a continuous circulation. At the same time, steam enters sterilization tank 1 through air inlet pipe 5, providing the high-temperature environment required for sterilization. The stirring blade assembly 15 continues to rotate, ensuring that the dairy products are fully mixed in the high-temperature steam environment, achieving uniform sterilization. By adjusting the stabilizing effect of the auxiliary mechanism, the steam flow rate is precisely controlled to maintain a constant temperature inside sterilization tank 1. After the predetermined sterilization time is reached, the steam supply is turned off, and circulation pump 2 is stopped. The sterilized dairy products can then undergo further processing.
