Technical Field
[0001] This utility model relates to the field of food processing equipment technology, and in particular to a device for preparing formula milk with added human milk oligosaccharides. Background Technology
[0002] Human milk oligosaccharides (HMOs) are the third largest solid component in breast milk after lactose and fat. There are more than 200 types of HMOs with complex and diverse structures. HMOs play a significant role in regulating the gut microbiota of infants, enhancing immunity, promoting brain development, and antibacterial properties. Currently, the application of HMOs in infant formula is mainly to mimic the nutritional components of breast milk, thereby improving the health of infants.
[0003] Existing equipment for preparing milk using human milk oligosaccharides (HMI) is prone to uneven mixing of HMI and milk during production, leading to clumping. This has several adverse effects on product quality. First, uneven distribution of HMI may prevent its bioactivity from being fully realized, reducing the nutritional value of the milk. Second, clumping reduces the taste and texture of the milk, affecting the drinking experience. Furthermore, clumping can cause equipment blockage, increasing production costs and maintenance difficulties. These problems not only affect the stability of product quality but also limit the efficient utilization of HMI in milk. To address these issues, we have developed a device for preparing formula milk with added HMI. Utility Model Content

[0023] The anti-clogging mechanism includes a first motor 4, which is a dual-shaft motor. The first motor 4 is installed on the top of the premix tank 12.

Several stirring rods 131 are fixedly connected to the outside of the second rotating shaft 13. Several pressure rollers 15 are rotatably connected to the bottom of the outer wall of the second rotating shaft 13. The second rotating shaft 13 drives the pressure rollers 15 to rotate in a plane on one hand, and drives the rotating rod inside the pressure rollers 15 to rotate on the other hand, so that the pressure rollers 15 can rotate in a plane and rotate around their own rotating rods at the same time. Several protrusions 16 are fixedly connected to the several pressure rollers 15, and the height of the protrusions 16 increases from the outside to the inside.
[0024] The anti-clogging mechanism also includes a through-hole plate 14. The through-hole plate 14 is fixedly connected to the bottom of the premix tank 12. The bottom of the second rotating shaft 13 is rotatably connected to the through-hole plate 14. Multiple through holes are opened on the through-hole plate 14. The protrusion 16 corresponds to the through holes on the through-hole plate 14, so that the pressure roller 15 does not affect the downward flow of the premixed solution while rotating, ensuring the continuity of stirring and effectively solving the problem of clumping and clogging in the traditional process. When the protrusion 16 moves, it can cooperate with the through holes on the through-hole plate 14. An inclined hole column 17 is fixedly connected to the bottom of the through-hole plate 14.

The first gear 8 and the second gear 9 are meshed. A straight cylinder 10, fixedly connected to the storage tank 5, is rotatably connected to the bottom of the second gear 9. The bottom of the straight cylinder 10 adopts a support rod structure design, which not only enhances the overall stability of the device but, more importantly, facilitates the smooth flow of the human milk oligosaccharides into the conveying auger 11. To ensure smooth discharge, the bottom support rod of the straight cylinder 10 extends into the interior of the storage tank 5 and is fixedly connected to the storage tank 5. The bottom of the second gear 9 is fixedly connected to a round shaft 112, which is located inside the straight cylinder 10 and is rotatably connected to the straight cylinder 10. The bottom of the round shaft 112 is fixedly connected to a transmission auger 11. The bottom of the storage tank 5 has a through-hole for discharging. The transmission auger 11 is slidably connected to the discharging hole of the storage tank 5. The bottom of the storage tank 5 is fixedly connected to a feeding bucket 111, which corresponds to the discharging hole. The support plate 18 has a first material transfer pipe 19 inside, one end of which is connected to the premix tank 12.
[0026] It also includes a second motor 20, which is installed at the bottom of the mixing tank 3. The output shaft of the second motor 20 extends into the interior of the mixing tank 3 and is fixedly connected to a third rotating shaft 23. Several stirring rods 232 are fixedly connected to the outside of the third rotating shaft 23. The stirring rods 232 are located inside the mixing tank 3. A conical protrusion 231 is provided on the top of the third rotating shaft 23.
[0027] It also includes a guide pipe 22, the top of the third rotating shaft 23 is rotatably connected to the guide pipe 22, the side of the guide pipe 22 has several square grooves vertically opened, the conical protrusion 231 is located inside the guide pipe 22, the top of the guide pipe 22 is fixedly connected to the second material transfer pipe 21, the second material transfer pipe 21 passes through the support plate 18 and is fixedly connected to the bottom of the storage box 2, and the other end of the first material transfer pipe 19 is connected to the second material transfer pipe 21.
[0028] In operation, the worker first adds milk to the storage tank 2. At this time, the valves at the bottom of the storage tank 2 and at the bend 121 are closed. After filling the storage tank 2 with milk, the valve at the bend 121 is opened, and some milk flows through the bend 121 into the premixing tank 12 as a premixed solution. Simultaneously, the worker adds powdered human milk oligosaccharides (HMI) into the storage tank 5 through the inlet 6. It is worth noting that the ratio of HMI powder to the total amount of milk is the same to ensure that the final solution has the standard HMI concentration. Then, the first motor 4 is started, and its upper output shaft drives the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the first gear 8 to rotate, the first gear 8 drives the second gear 9 to rotate, and the second gear 9 drives the circular shaft 112 to rotate. The circular shaft 112 further drives the conveying auger 11 to rotate, forming a continuous feeding and conveying system. During the rotation of the conveying auger 11, it can quantitatively convey the human milk oligosaccharide to the feeding bucket 111, and then from the feeding bucket 111 to the premixing tank 12, realizing the continuous conveying of human milk oligosaccharide. At this time, the bottom valve of the premixing tank 12 is closed. At the same time, the lower output shaft of the first motor 4 drives the second rotating shaft 13 to rotate. The stirring rod 131 and the pressure roller 15 fixed on the second rotating shaft 13 also rotate. The stirring rod 131 drives the milk flowing into the premixing tank 12 from the bend pipe 121 to mix and pre-stir with the human milk oligosaccharide discharged from the feeding bucket 111. The purpose is to ensure that the human milk oligosaccharide can fully mix with the premixed solution in the premixing tank 12. Mixing is performed more efficiently in the premixing tank 12 because its smaller capacity compared to the mixing tank 3 improves mixing efficiency. After initial mixing, the human milk oligosaccharides and premixed solution form a premixed solution. This premixed solution passes through the perforated plate 14 at the bottom of the premixing tank 12 to complete subsequent steps. When the premixed solution reaches two-thirds of the water level in the premixing tank 12, the bottom valves of the premixing tank 12 and the storage tank 2 are opened simultaneously. According to fluid dynamics principles, the milk is diverted to two different paths: one part flows into the premixed solution at the bend 121, and the other part flows directly into the mixing tank 3 through the second feed pipe 21 and the guide pipe 22 via the bottom opening of the storage tank 2, serving as the base solution. As the premixed solution passes through the perforated plate 14… To prevent insufficient mixing from causing clumping of human milk oligosaccharides (HMOs), these clumps may remain on the surface of the perforated plate 14 or in its internal perforations, affecting the subsequent passage of the premixed solution through the plate 14. When the second rotating shaft 13 rotates, it drives the pressure roller 15 to rotate. The pressure roller 15 drives the protrusions 16 to squeeze the HMO clumps in the perforated plate 14. The pressure roller 15 crushes the clumps remaining on the surface of the plate 14, while the protrusions 16 crush the HMO clumps in the perforated plate 14. At this point, all clumps are crushed and mixed with the premixed solution before flowing out of the plate 14. The premixed solution then undergoes a diversion process through the inclined holes on the inclined column 17, further crushing the clumps and mixing them with the premixed solution.At this time, the premixed solution flows into the first transfer pipe 19 through the inclined column 17, and then into the second transfer pipe 21. When the premixed solution, after stirring, flows from the first transfer pipe 19 into the second transfer pipe 21, the base solution simultaneously flows from the bottom of the storage tank 2 into the second transfer pipe 21. This achieves the second mixing of the premixed solution and the base solution. Finally, it is discharged into the mixing tank 3 through the square groove of the guide pipe 22. As the mixed solution is discharged from the guide pipe 22, the conical structure at the top of the conical protrusion 231 changes the direction of water flow in the mixed solution, making the mixture... The mixed solution is discharged from the square groove of the flow pipe 22. At this time, the second motor 20 is started. The output shaft of the second motor 20 drives the third rotating shaft 23 to rotate, which in turn drives the stirring rod 232 to rotate, thoroughly stirring the mixed solution to ensure that the premixed solution and milk are completely mixed. When the remaining milk level in the storage tank 2 is lower than the height of the bend 121, and the premixed solution in the premix tank 12 has completely flowed into the stirring tank 3, the first motor 4 is turned off. After the mixing in the stirring tank 3 is completed, the second motor 20 is turned off, and finally the valve of the discharge port 24 is opened to allow the fully mixed solution to be discharged from the discharge port 24.
