[0029] Please see Figure 1-4 This utility model provides a technical solution:
[0030] A multifunctional dairy product testing stirring device includes a dairy product stirring tank 1. Four reinforcing legs 2 are fixedly connected to the lower end of the dairy product stirring tank 1. An external threaded groove 3 is opened on the upper part of the outer surface of the dairy product stirring tank 1. A detachable stirring device 5 is arranged on the top of the dairy product stirring tank 1. The lower part of the detachable stirring device 5 is located inside the dairy product stirring tank 1. An operation keyboard 4 is fixedly connected to the front of the outer surface of the dairy product stirring tank 1. A through pipe 6 is fixedly connected to the lower right part of the dairy product stirring tank 1. A control valve 7 is arranged on the right side of the outer surface of the through pipe 6. A dairy product detector 8 is fixedly connected to the end of the through pipe 6 away from the dairy product stirring tank 1.
[0031] In this embodiment, the detachable stirring device 5 includes a stirring cover 51. A feed pipe 52 is fixedly connected to the upper left part of the stirring cover 51, and a stirring assembly 53 is fixedly connected to the upper middle part of the stirring cover 51. The lower part of the stirring assembly 53 is located inside the stirring dairy tank 1. The stirring cover 51 is detachably connected to the stirring dairy tank 1 via an external threaded groove 3. The feed pipe 52 communicates with the interior of the stirring dairy tank 1. The stirring assembly 53 includes a servo motor 531, which is fixedly connected to the upper end of the stirring cover 51. The output end of the servo motor 531 passes through the upper middle part of the stirring cover 51 and is fixedly connected to a connecting rod 532. Three upper-level flat blade groups 53 are fixedly connected to the upper part of the outer surface of the connecting rod 532. 3. Three middle-layer inclined stirring blade groups 534 are fixedly connected to the middle of the outer surface of the connecting rod 532. Three bottom-layer anchor stirring blade groups 535 are fixedly connected to the lower part of the outer surface of the connecting rod 532. A cleaning brush assembly 536 is fixedly connected to the upper part of the outer surface of the connecting rod 532. The cleaning brush assembly 536 is located directly above the three upper-layer flat blade groups 533. The three upper-layer flat blade groups 533, the three middle-layer inclined stirring blade groups 534, and the three bottom-layer anchor stirring blade groups 535 are all located inside the mixing tank 1. The three upper-layer flat blade groups 533 are alternately staggered with the three middle-layer inclined stirring blade groups 534. The three middle-layer inclined stirring blade groups 534 are alternately staggered with the three bottom-layer anchor stirring blade groups 535.
[0032] The above scheme achieves efficient mixing through the stirring assembly 53. The servo motor 531 drives the connecting rod 532 to rotate, which in turn drives the upper flat blade assembly 533, the middle inclined stirring blade assembly 534, and the bottom anchor stirring blade assembly 535. The upper flat blade assembly 533 breaks up the liquid surface and prevents foaming; the middle inclined stirring blade assembly 534 enhances axial flow; and the bottom anchor stirring blade assembly 535 pushes the material at the bottom. These blades are alternately and staggered, forming a complex mixing flow field, avoiding dead zones, and enabling thorough mixing of dairy products containing different components such as particles, fat globules, and protein clots. Simultaneously, the cleaning brush assembly 536 cleans the inner wall of the mixing tank 1 during mixing. The stirring cover 51 is detachably connected to the mixing tank 1 via the external threaded groove 3, facilitating assembly and cleaning. The feed pipe 52 allows for the addition of materials as needed. This makes the entire mixing device compact and functionally complete, effectively solving the problem of insufficient mixing in traditional mixing devices.
[0033] In this embodiment, the cleaning brush assembly 536 includes a reinforcing ring block 5361. The upper end of the reinforcing ring block 5361 has a through connection hole 5362. Three cleaning brush bodies 5363 are fixedly connected to the outer surface of the reinforcing ring block 5361. The reinforcing ring block 5361 is fixedly connected to the connecting rod 532 through the connection hole 5362. The three cleaning brush bodies 5363 are respectively pressed against the inner wall of the stirring dairy tank 1 but not fixed.
[0034] Through the above scheme: the reinforcing ring block 5361 is fixedly connected to the connecting rod 532 through the connecting hole 5362, and the three cleaning brush bodies 5363 on it rotate with the connecting rod 532. When the stirring device is working, the cleaning brush bodies 5363 are pressed against the inner wall of the stirring dairy tank 1 but not fixed, which can effectively remove residual dairy products from the inner wall of the tank. Since dairy products have sticky and easy-to-residue characteristics, the cleaning brush bodies 5363 can prevent residues from adhering, avoid microbial growth, and reduce cross-contamination. The reinforcing ring block 5361 ensures the structural stability of the cleaning brush assembly 536. In this way, during the stirring process, not only can dairy products of different components be fully stirred, but the cleaning brush assembly 536 can also perform synchronous self-cleaning to ensure the cleanliness of the container and stirring paddle, ensure the accuracy of subsequent testing work, and avoid potential hazards caused by residues.
[0035] It should be noted that this utility model is a multifunctional stirring device for dairy product testing. During use, the dairy product to be tested is first placed into the stirring dairy tank 1 through the feeding pipe 52. The operation keyboard 4 can be used to set relevant stirring parameters. The servo motor 531 is started, and its output drives the connecting rod 532 to rotate. The three upper-layer flat blade groups 533, three middle-layer inclined stirring blade groups 534, and three bottom-layer anchor-type stirring blade groups 535 on the connecting rod 532 rotate accordingly. Because they are alternately staggered, they can form a complex stirring flow field. The upper-layer flat blade groups 533 can break the liquid surface, and the middle-layer inclined stirring blade groups 534 enhance... Axial flow is achieved by the bottom anchor-type stirring blade assembly 535 pushing the material at the bottom to fully stir the dairy products of different components. At the same time, the reinforcing ring block 5361 in the cleaning brush assembly 536 is fixed to the connecting rod 532 through the connecting hole 5362. The three cleaning brush bodies 5363 will press tightly against the inner wall of the stirring dairy tank 1 to clean the inner wall during the stirring process and prevent dairy residue. After stirring is completed, the control valve 7 is opened, and the stirred dairy products are transported to the dairy product detector 8 for testing through the pipe 6. Therefore, the overall accessories work together to improve the accuracy and reliability of dairy product testing, providing an efficient, convenient and hygienic solution for dairy product testing.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
