[0002] In the food industry, sour dairy products, with their unique sweet-sour taste and rich nutritional value, hold a prominent position. These products, such as yogurt and sour milk drinks, not only satisfy consumers' dual pursuit of deliciousness and health, but also have gained widespread market recognition for their diverse flavors and formats. However, the high viscosity and tendency to separate sour dairy products pose significant challenges to the mixing process during production and processing.

[0003] After searching, the Chinese utility model patent with authorization announcement number CN220110919U is a dairy raw material stirring device.

When the circular plate moves upward, the raw materials enter the heat conduction pipe through the circular pipe one and are re-conveyed into the tank body through the circular pipe two. In this process, the purpose of cooling the raw materials is achieved through the action of the refrigerator and the heat conduction pipe; when the circular plate moves in the opposite direction, the raw materials flow in the opposite direction through the action of the circular pipe two, the heat conduction pipe and the circular pipe one, and the stirring of the raw materials is achieved through the repeated sliding of the circular plate.

[0021] The following is combined with Figure 1-4 The specific implementation methods of the present utility model are further described in detail.

[0022] like Figure 1-4 As shown, the present invention is a stirring device for a batching tank for milk processing, comprising a tank base 10, a tank body 11 for accommodating dairy products fixed to the tank base 10, a tank cover 12 fixed to the upper end of the tank body 11, a refrigerator 20 fixed to the side of the tank body 11, a heat pipe 21 provided inside the refrigerator 20, and the upper and lower ends of the heat pipe 21 are respectively connected to the upper and lower ends of the tank body 11. When the dairy product flows in the heat pipe 21, the refrigerator 20 can cool the dairy product in the heat pipe 21. In addition to the above-mentioned prior art, the stirring device for the batching tank for milk processing of the present invention also includes:

[0023] A threaded rod 50, wherein the lower end of the threaded rod 50 is fixedly connected to the inner lower end of the tank body 11, and the axis of the threaded rod 50 is arranged to coincide with the axis of the tank body 11;

[0024] The circular plate 30 is threadedly mounted on the threaded rod 50 via a threaded sleeve 51 fixed at the center of the circular plate 30. It is understood that when the circular plate 30 rotates on the threaded rod 50, it moves in the length direction of the threaded rod 50. When the circular plate 30 moves up and down in the length direction of the threaded rod 50, it squeezes the dairy products in the upper and lower parts of the tank body 11 located on the circular plate 30, causing them to flow back and forth in the heat conducting pipe 21. The flow not only has a cooling effect, but also has a simple mixing effect.

[0025] Due to the high viscosity and easy stratification characteristics of dairy raw materials, dairy products may face problems such as uneven raw material flow and limited stirring effect when flowing in the heat pipe 20. Therefore, in order to increase the stirring effect of dairy products, a stirring component 40 is also provided inside the tank body 11.

[0026] In some embodiments, the stirring assembly 40 includes a stirring blade 42 and a stirring blade driving device 41. The stirring blade driving device 41 is provided on the tank cover 12 and is used to drive the stirring blade 42 to perform a circular motion around the center of the tank body 11. Specifically, the stirring blade 42 is a thin sheet structure and is uprightly arranged in the tank body 11. The circular plate 30 is penetrated by a transmission groove 31, and the stirring blade 42 penetrates the transmission groove 31. When in use, the stirring blade driving device 41 drives the stirring blade 42 to rotate in the tank body 11 to stir the milk. During the stirring process, since the stirring blade 42 is limited in the transmission groove 31, the stirring blade 42 will also drive the circular plate 30 to rotate during the rotation. When the circular plate 30 rotates, it automatically moves in the length direction of the threaded rod 50 under the limiting action of the threaded rod 50. When the circular plate 30 moves, it will squeeze the milk in the tank body 11, causing it to flow in the heat pipe 21 to achieve cooling. At the same time, under the stirring action of the stirring blade 42, the mixing effect of the milk in the tank body 11 is increased, and the milk ingredients are made more uniform.

[0027] There are at least two stirring blades 42 , and the upper ends of the stirring blades 42 are connected via a connecting piece 43 . The stirring blade driving device 41 is disposed on the tank cover 12 to drive the connecting piece 43 to rotate around the center of the tank body 11 .

[0028] In some embodiments, the stirring blade driving device 41 is a servo motor, which can drive the connecting member 43 to rotate in the forward and reverse directions. When the connecting member 43 rotates in the forward and reverse directions, it drives the stirring blade 42 to rotate in the forward and reverse directions. When the stirring blade 42 rotates in the forward and reverse directions, the circular plate 30 moves up and down in the tank body 11.

[0029] Furthermore, the transmission groove 31 passes through the side of the circular plate 30, and the side of the stirring blade 42 slides in contact with the inner wall of the tank body 11. In this way, the stirring blade 42 will also slide on the inner wall surface of the tank body 11 during stirring, thereby preventing the milk from sticking to the inner wall of the tank body 11.

[0030] In some embodiments, in order to facilitate cleaning of the interior of the tank 11, as shown in FIG. Figure 3 As shown, the tank cover 12 is detachably fixed to the upper end of the tank body 11 by a fixing member 60. The fixing member 60 can be any one of a bolt and a snap-fit ​​structure. When the tank cover 12 is removed, the stirring assembly 40 can be removed from the tank body 11 as a whole for easy cleaning.

[0031] The core of the stirring device of the ingredient tank for milk processing of the present invention lies in the exquisite coordination between the stirring assembly and the circular plate. The stirring assembly is composed of a stirring blade 42 and a stirring blade driving device 41 (such as a servo motor) on the tank cover 12. The stirring blade 42 is driven by the connecting piece 43 to rotate around the center of the tank body 11. While directly stirring the dairy product, the side of the stirring blade 42 contacts the transmission groove 31 on the circular plate 30, transmitting the rotational force to the circular plate 30 to achieve synchronous rotation. The circular plate 30 is threadedly mounted on the threaded rod 50 through the threaded sleeve 51 at the center of its circle. During the rotation process, it is limited by the threaded rod 50 and automatically moves up and down in the tank body. This up and down movement process squeezes the dairy product, forcing it to circulate in the heat pipe 21, which not only effectively cools it down, but also significantly improves the uniformity of the dairy product through continuous mixing, thereby achieving the dual high-efficiency goals of stirring and cooling.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
