Description

Technical Field

[0001] This invention relates to the field of yak milk processing technology, and in particular to a yak milk sterilization and disinfection device. Background Technology

[0002] The core function of yak milk sterilization is to build a crucial safety barrier while preserving its natural nutritional value and unique flavor. Although raw yak milk from the high plateau is rich in rare nutrients, it easily carries various microorganisms, posing a risk of spoilage or foodborne illness if consumed directly. Precise heat treatment processes such as pasteurization or ultra-high temperature sterilization can effectively kill pathogenic and spoilage bacteria, significantly delaying rancidity, thus ensuring safety and extending shelf life. Pasteurization typically uses a high-temperature short-time method, maintaining 72-75°C for 15-30 seconds, to better preserve the original natural immune-active proteins, rich flavor, and some probiotics in yak milk.

[0003] A search revealed Chinese patent application CN119032990A, which discloses a preheating milk sterilization device, comprising: a conveying mechanism, conveying pipes, a hot water frame, a stirring mechanism, and a driving mechanism. The driving mechanism synchronously drives the stirring and conveying mechanisms, allowing for the intermittent extraction of milk to be sterilized from a second milk tank. When processing yak milk with a high fat content, prolonged use can easily lead to sediment and solids forming inside the heating pipes. If left untreated, this can result in poor heating efficiency and blockages affecting flow rate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a yak milk sterilization and disinfection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A yak milk sterilization device includes multiple heating tubes installed in a sterilization tank. The bottom of each heating tube is fixedly connected to a mounting base, and a stirring shaft is rotatably connected to the upper end of the mounting base. Multiple scrapers are rotatably connected to the outside of the stirring shaft, and an adjusting gear is fixedly connected to the inside of each scraper. An adjusting rod is slidably connected to the inside of the stirring shaft, and multiple adjusting gears are fixedly connected to the outside of the adjusting rod. One side of the adjusting gear and the adjusting gear mesh with each other. A rotary drive assembly is fixedly connected above the stirring shaft.

[0006] Preferably, the heating tube is fixedly connected to a feed pipe at its upper end and a discharge pipe at its lower end. A cleaning top cover is rotatably connected above the stirring shaft. Mounting platforms are fixedly connected to both ends of the cleaning top cover, and the mounting platforms are fixedly connected to the feed pipe.

[0007] Furthermore: the rotary drive assembly includes a stirring motor, an assembly plate, a drive gear ring, and a drive gear. One end of the drive gear ring is fixedly connected to the upper end of the stirring shaft, and the drive gear ring and one end of the stirring shaft are rotatably connected to the assembly plate. The other end of the assembly plate is fixedly connected to the stirring motor, and the drive gear is fixedly connected to the power output end of the stirring motor. The drive gear and the drive gear ring mesh with each other.

[0008] Furthermore: a drive bracket is fixedly connected above the cleaning top cover, a lifting drive rod is fixedly connected below the drive bracket, a sliding limit frame is fixedly connected to the other end of the drive bracket, a sliding limit plate is slidably connected to the upper end of the sliding limit frame, a bearing is fixedly connected to the other end of the sliding limit plate, and the movable end of the inner side of the bearing is fixedly connected to the outer side of the adjusting rod.

[0009] As a preferred embodiment of the present invention: an inlet is fixedly connected to the top of the disinfection tank, and an outlet is fixedly connected to the bottom of the disinfection tank.

[0010] As a further embodiment of the present invention: a translation screw is rotatably connected above one side of the disinfection tank, a translation motor is fixedly connected above the disinfection tank, the translation screw is fixedly connected to the power output end of the translation motor, and a translation nut is slidably connected above the disinfection tank, with the inner thread of the translation nut connected to the translation screw.

[0011] As a further embodiment of the present invention: a lifting motor and a lifting guide rail are fixedly connected above the translation nut, a lifting screw is fixedly connected to the power output end of the lifting motor, the other end of the lifting screw is fixedly connected to the lifting guide rail, a limit rod is fixedly connected to one end of the lifting motor and the lifting guide rail, a lifting nut is slidably connected below the limit rod, and the middle part of the lifting nut is threadedly connected to the lifting screw.

[0012] Based on the aforementioned scheme: a lifting drive rod is fixedly connected to one side of the lifting nut, and a translation limit groove is fixedly connected to the top of the lifting drive rod.

[0013] Based on the aforementioned scheme: a lifting plate is fixedly connected to one side of the lifting drive rod, and a lifting positioning groove matching the shape of the lifting plate is opened on one side of the drive bracket.

[0014] Based on the aforementioned scheme: an anti-deviation boss is fixedly connected to one side of the adjusting rod, and multiple upper and lower limiting rings are fixedly connected to the inner side of the stirring shaft. The anti-deviation boss and the stirring shaft are slidably connected within the upper and lower limiting rings.

[0015] The beneficial effects of this invention are as follows: A yak milk sterilization device improves heating uniformity and cleaning efficiency through an adjustable scraper design. During sterilization, the scraper is rotated to a vertical position under the transmission of the adjusting rod and gear rack, and the rotating stirring shaft can stir the yak milk in the tube to ensure uniform heating. During cleaning, the adjusting rod is pulled to make the scraper turn horizontal and combine into a complete circle. While the stirring shaft is pulled out, the adhering substances on the inner wall of the tube are scraped off, achieving self-cleaning, reducing the amount of manual cleaning work, and is easy to operate and has low maintenance costs.

[0016] A yak milk sterilization device automates the maintenance of multiple heating tubes through a lifting and translation mechanism. The lifting motor drives the lead screw to move the lifting nut up and down. The angle of the scraper is adjusted first by the lifting drive rod, and then the stirring shaft is lifted as a whole. The translation motor can adjust the position of the lifting mechanism so that the translation limit groove is aligned with the sliding limit plate above different heating tubes, realizing the sequential positioning and extraction of each heating tube. It is suitable for multi-tube systems and improves the automation and efficiency of equipment maintenance. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent. Example

[0021] A yak milk sterilization device, such as Figures 1-8 As shown, the device includes multiple heating tubes 4 installed inside a disinfection tank 1. The bottom of each heating tube 4 is fixedly connected to a mounting base 32. A stirring shaft 17 is rotatably connected to the upper end of the mounting base 32. Multiple scrapers 31 are rotatably connected to the outer side of the stirring shaft 17. The edges of the scrapers 31 are made of food-grade silicone. An adjusting gear 36 is fixedly connected to the inner side of the scrapers 31. An adjusting rod 20 is slidably connected to the inner side of the stirring shaft 17. Multiple adjusting gears 37 are fixedly connected to the outer side of the adjusting rod 20. One side of the adjusting gears 37 and the adjusting gears 36 mesh with each other. A rotary drive assembly is fixedly connected above the stirring shaft 17. The disinfection tank 1 is fixedly connected to an inlet 2 at the top and an outlet 3 at the bottom. The inlet 2 and outlet 3 can be connected to an external water supply and drainage device for replacing the heated water. The upper end of the heating tube 4 is fixedly connected to the feed pipe 5, and the lower end is fixedly connected to the discharge pipe 6. The cleaning top cover 16 is rotatably connected above the stirring shaft 17. The two ends of the cleaning top cover 16 are fixedly connected to the mounting platform 24, which is fixedly connected to the feed pipe 5. When in use, fill the disinfection tank 1 with hot water at 72-75°C and keep it warm. Then, put the yak milk in through the feed pipe 5. The yak milk passes through the inside of the disinfection tank 1. The discharge pipe 6 has an electric switch and a flow meter at one end, which can be used to monitor the milk flow rate and keep the time for the yak milk to pass through the disinfection tank 1 within 15-30 seconds. To ensure that the yak milk flows smoothly and is heated evenly as it passes through the heating tube 4, after the stirring shaft 17 is installed on the mounting base 32, the adjusting rod 20 is pushed downwards. This simultaneously moves multiple adjusting gears 37 downwards, causing the adjusting gears 36 to rotate, so that the scraper 31 rotates to a position perpendicular to the cross-section of the stirring shaft 17. In this way, when the rotary drive assembly drives the stirring shaft 17 to rotate, the yak milk passing through the heating tube 4 can be stirred, ensuring even heating. When the heating tube 4 needs to be cleaned and maintained regularly, when removing the stirring shaft 17, first pull out the adjusting rod 20. At this time, multiple adjusting gears 37 will drive the scraper 31 to rotate to a state that is horizontal with the cross section of the stirring shaft 17. This allows multiple scrapers 31 to form a complete circle. In the subsequent process of removing the stirring shaft 17, multiple scrapers 31 can scrape off the solid matter attached to the inner wall of the heating tube 4 while rotating. After that, only a simple rinse is needed inside the heating tube 4. No further manual cleaning is required. The operation is simple. The rotary drive assembly includes a stirring motor 25, an assembly plate 26, a drive gear ring 27, and a drive gear 28. One end of the drive gear ring 27 is fixedly connected to the upper end of the stirring shaft 17, and the drive gear ring 27 and one end of the stirring shaft 17 are rotatably connected to the assembly plate 26. The other end of the assembly plate 26 is fixedly connected to the stirring motor 25, and the drive gear 28 is fixedly connected to the power output end of the stirring motor 25. The drive gear 28 and the drive gear ring 27 mesh with each other. A drive bracket 18 is fixedly connected above the cleaning top cover 16, and a lifting drive rod 15 is fixedly connected below the drive bracket 18. A sliding limit frame 21 is fixedly connected to the other end of the drive bracket 18. A sliding limit plate 22 is slidably connected to the upper end of the sliding limit frame 21. A bearing 23 is fixedly connected to the other end of the sliding limit plate 22. The movable end of the inner side of the bearing 23 is fixedly connected to the outer side of the adjusting rod 20. The cleaning top cover 16 has a sealing silicone sealant on its edge and can be fixed above the feed pipe 5 with bolts. When the heating tube 4 needs to be disassembled and maintained, the bolts can be removed to move the cleaning top cover 16 and the stirring shaft 17 upwards. Simultaneously, when the stirring motor 25 is working, it can drive the stirring shaft 17 to rotate, stir and scrape solids. The sliding limit frame 21 and the sliding limit plate 22 can work with the bearing 23 to ensure the stability of the adjusting rod 20.

[0022] like Figures 1-8As shown, a translation screw 8 is rotatably connected to the upper side of the disinfection tank 1, a translation motor 7 is fixedly connected to the upper side of the disinfection tank 1, the translation screw 8 is fixedly connected to the power output end of the translation motor 7, and a translation nut 9 is slidably connected to the upper side of the disinfection tank 1, with the inner thread of the translation nut 9 connected to the translation screw 8. A lifting motor 10 and a lifting guide rail 12 are fixedly connected above the translation nut 9. A lifting screw 11 is fixedly connected to the power output end of the lifting motor 10. The other end of the lifting screw 11 is fixedly connected to the lifting guide rail 12. A limit rod 14 is fixedly connected to one end of the lifting motor 10 and the lifting guide rail 12. A lifting nut 13 is slidably connected below the limit rod 14. The middle part of the lifting nut 13 is threaded to the lifting screw 11. A lifting drive rod 15 is fixedly connected to one side of the lifting nut 13, and a translation limit groove 29 is fixedly connected to the top of the lifting drive rod 15. When the lifting screw 11 is started, the lifting nut 13 can be driven to move up and down through the lifting screw 11. In this way, the lifting drive rod 15 installed on one side of the lifting nut 13 can be used to drive the translation limit groove 29 that is fastened to one end of the sliding limit plate 22 to move upward. This can first drive the adjusting rod 20 to move upward, adjust the angle of the scraper 31, and then drive the stirring shaft 17 to move upward and remove the stirring shaft 17. The translation motor 7 below drives the translation screw 8 to rotate, which can change the position of the lifting screw 11. In this way, the translation limit groove 29 can be used to fix it to one end of different sliding limit plates 22. It can be used for cleaning and maintenance of devices with multiple heating tubes 4 installed.

[0023] In this embodiment, when in use, hot water at 72-75°C is filled into the disinfection tank 1 and kept warm. Then, yak milk is introduced through the feed pipe 5. The yak milk passes through the inside of the disinfection tank 1. One end of the discharge pipe 6 has an electric switch and a flow meter, which can be used to monitor the flow rate of the milk and keep the time for the yak milk to pass through the disinfection tank 1 within 15-30 seconds. To ensure that the yak milk flows smoothly and is heated evenly as it passes through the heating tube 4, after the stirring shaft 17 is installed on the mounting base 32, the adjusting rod 20 is pushed downwards. This simultaneously moves multiple adjusting gears 37 downwards, causing the adjusting gears 36 to rotate, so that the scraper 31 rotates to a position perpendicular to the cross-section of the stirring shaft 17. In this way, when the rotary drive assembly drives the stirring shaft 17 to rotate, the yak milk passing through the heating tube 4 can be stirred, ensuring even heating. When the heating tube 4 needs to be cleaned and maintained regularly, when removing the stirring shaft 17, first pull out the adjusting rod 20. At this time, multiple adjusting gears 37 will drive the scraper 31 to rotate to a state that is horizontal with the cross section of the stirring shaft 17. This allows multiple scrapers 31 to form a complete circle. In the subsequent process of removing the stirring shaft 17, multiple scrapers 31 can scrape off the solid matter attached to the inner wall of the heating tube 4 while rotating. After that, only a simple rinse is needed inside the heating tube 4. No further manual cleaning is required. The operation is simple. The cleaning top cover 16 has a sealing silicone sealant on its edge and can be fixed above the feed pipe 5 with bolts. When the heating tube 4 needs to be disassembled and maintained, the bolts can be removed to move the cleaning top cover 16 and the stirring shaft 17 upwards. Simultaneously, when the stirring motor 25 is working, it can drive the stirring shaft 17 to rotate, stir and scrape solids. The sliding limit frame 21 and the sliding limit plate 22 can work with the bearing 23 to ensure the stability of the adjusting rod 20. When the lifting screw 11 is started, the lifting nut 13 can be driven to move up and down through the lifting screw 11. In this way, the lifting drive rod 15 installed on one side of the lifting nut 13 can be used to drive the translation limit groove 29 that is fastened to one end of the sliding limit plate 22 to move upward. This can first drive the adjusting rod 20 to move upward, adjust the angle of the scraper 31, and then drive the stirring shaft 17 to move upward and remove the stirring shaft 17. The translation motor 7 below drives the translation screw 8 to rotate, which can change the position of the lifting screw 11. In this way, the translation limit groove 29 can be used to fix it to one end of different sliding limit plates 22. It can be used for cleaning and maintenance of devices with multiple heating tubes 4 installed. Example

[0024] A yak milk sterilization device, such as Figures 1-8 As shown, a lifting plate 30 is fixedly connected to one side of the lifting drive rod 15, and a lifting positioning groove 19 matching the shape of the lifting plate 30 is opened on one side of the drive bracket 18. When the lifting drive rod 15 is at its lowest position, the top of the lifting plate 30 is lower than the drive bracket 18. When the translation limit groove 29 is aligned with the sliding limit plate 22, the lifting drive rod 15 moves upward to insert the lifting plate 30 into the lifting positioning groove 19, allowing the drive bracket 18 and the cleaning top cover 16 to move upward, making their movement more stable and preventing them from slipping off the side.

[0025] like Figures 1-8 As shown, an anti-deviation boss 35 is fixedly connected to one side of the adjusting rod 20, and multiple upper limiting rings 33 and lower limiting rings 34 are fixedly connected to the inner side of the stirring shaft 17. The anti-deviation boss 35 and the stirring shaft 17 are slidably connected within the upper limiting rings 33 and lower limiting rings 34. The upper limiting ring 33 and the lower limiting ring 34 can limit the uppermost and lowermost movement range of the adjusting toothed rod 37, which can further limit the rotation angle of the scraper 31. The anti-deviation boss 35 can ensure that the adjusting rod 20 rotates synchronously with the stirring shaft 17.

[0026] The above description represents a preferred embodiment of the present invention. The scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention, combined with existing technology or common knowledge, and within the spirit and principles of the present invention, should be covered within the scope of protection of the present invention.
