Please refer to fig. 1, which is a schematic structural diagram of a yogurt stirring temperature control device according to an embodiment of the present application. As can be seen from fig. 1, the present application provides a yogurt stirring temperature control device, which includes a housing 1, a stirring unit 2, and a transmission unit 3; the stirring unit 2 and the transmission unit 3 are disposed inside the housing 1, wherein the housing 1 includes an inner housing 11 and an outer housing 12, and the inner housing 11 is divided into an upper isolation space 4 and a lower stirring space 5 by an isolation plate 13.

As shown in fig. 3, the stirring unit 2 includes a main stirring device 21 and a secondary stirring device 22, the main stirring device 21 is a main functional unit for stirring raw materials of yogurt, and is disposed at a central position inside the casing 1, so that the raw materials at the central position and around the central position are fully mixed; the auxiliary stirring unit 22 is an auxiliary function unit for stirring the yogurt material and is located between the main stirring unit 21 and the inner casing 11, so that the material liquid close to the inner casing 11 and the corners can be fully mixed.
The main stirring device 21 includes a motor 211, a main rotating shaft 212 connected to the motor 211, and a plurality of groups of main stirring paddles 213 fixed to the main rotating shaft 212 along a vertical direction, and the auxiliary stirring device 22 includes an auxiliary rotating shaft 221 and a plurality of groups of auxiliary stirring paddles 222 fixed to the auxiliary rotating shaft 221 along a vertical direction. The master paddle 213 and the slave paddle 222 are disposed in the agitating space 5. The master paddles 213 can be arranged in 3-5 groups and the slave paddles 222 can be arranged in 2-7 groups, depending on the actual mixing requirements and the volume of the housing. In order to increase the stirring area of the master paddle 213, in the present embodiment, the length of the blade of the master paddle 213 is greater than that of the slave paddle 222. In addition, in order to improve the stirring efficiency of the main stirring paddles 213, the setting direction of each group of main stirring paddles 213 may be optimized, so that there is no overlapping area in the projection of the stirring blades on each group of main stirring paddles 213 in the vertical direction, so as to obtain a better stirring effect, and the setting direction of the auxiliary stirring paddles 222 may also be optimized in the above manner, which is not described herein again.
Referring to fig. 2, a schematic structural diagram of a transmission unit according to an embodiment of the present application is shown. As can be seen from fig. 1 and 2, the transmission unit 3 includes a first gear 31 fixed on the main rotating shaft 212, a second gear 32 fixed on the auxiliary rotating shaft 221, and a third gear 33 fixed on the inner housing 11, wherein the first gear 31, the second gear 32, and the third gear 33 are engaged with each other, and the second gear 32 is connected to the first gear 31 through a connecting shaft 34. The first gear 31 is driven by the motor to rotate, so as to drive the second gear 32 to rotate along the opposite direction, meanwhile, the second gear 32 rotates along the inner edge of the third gear under the meshing action of the third gear 33, the second gear 32 drives the slave stirring device 22 to rotate along the third gear 33, an effective supplementary stirring effect is achieved on the main stirring device 21, and therefore the yoghourt raw materials in the stirring space 5 are fully and uniformly stirred. For example, as shown in fig. 2, the first gear 31 is driven by the motor to rotate counterclockwise, the second gear 32 is driven by the first gear 31 to rotate clockwise, and the third gear 33 is meshed to revolve counterclockwise around the first gear 31 around the inner edge of the third gear.

In addition, the constant temperature water bath mode is adopted to avoid the temperature drop phenomenon in the stirring space, thereby ensuring the fermentation temperature of the yoghourt raw material. Specifically, this acidophilus milk stirring temperature control device still includes pan feeding mouth 61, discharge gate 62, heat preservation liquid entry 63 and heat preservation liquid outlet 64, pan feeding mouth 61 with discharge gate 62 runs through interior casing 11 with shell body 12, pan feeding mouth 61 set up in interior casing 11 with the upper end of shell body 12, discharge gate 62 set up in interior casing 11 with the lower extreme of shell body 12, heat preservation liquid entry 63 set up in the bottom of shell body 12, heat preservation liquid outlet 64 set up in the upper portion of shell body 12.
In the scheme, the main stirring device is a main functional unit for stirring the yoghourt raw materials, so that the raw material liquid in the central position and around is fully mixed; the auxiliary function unit for stirring the yoghourt raw material from the stirring device enables the raw material liquid close to the position of the inner shell and the corners to be fully mixed. The auxiliary stirring device plays an effective role in supplementing and stirring the main stirring device, so that the yoghourt raw materials in the stirring space are fully and uniformly stirred. In addition, the constant temperature water bath mode is adopted to avoid the temperature drop phenomenon in the stirring space, thereby ensuring the fermentation temperature of the yoghourt raw material.
In the initial stage of adding the yogurt raw material, the yogurt raw material and water have a strong heat exchange effect, which easily causes the temperature of the yogurt raw material to be unstable, and therefore, in other embodiments of the present application, the yogurt stirring temperature control device may further include a temperature control processing device 71, and a temperature sensor 72 and a heating wire 73 electrically connected to the temperature control processing device 71, where the temperature sensor 72 and the heating wire 73 are disposed in the stirring space 5. When the temperature sensor 72 detects that the temperature of the yogurt raw material is lower than a certain threshold value, the temperature control processing device 71 controls the heating wire 73 to heat the yogurt raw material, and when the temperature sensor 72 detects that the temperature of the yogurt raw material is higher than the certain threshold value, the temperature control processing device 71 controls the heating wire 73 to stop heating the yogurt raw material, so that temperature fluctuation caused by environment and process progress is avoided. Further optimally, the heating wire 73 is fixed at the bottom of the inner shell 11, and the temperature sensor 72 is arranged at the position corresponding to the heat preservation liquid outlet 64 on the inner shell 11, so that on one hand, the heating source can be far away, and on the other hand, the position of the heat preservation liquid outlet 64 can be close, thereby detecting the temperature change inside and outside more accurately.
Further optimally, the main stirring paddle 213 and the auxiliary stirring paddle 222 are arranged along the horizontal projection direction of the main rotating shaft 212 in a staggered mode, so that the stirring area of the stirring blade can be increased, the stirring blade can be stirred or crushed in different areas, and the stirring and crushing effects of the stirrer can be improved. In addition, in order to avoid the contact between the stirring blades of the master stirring paddle 213 and the slave stirring paddle 222, the radius of the circumference formed by the master stirring paddle 213 and the slave stirring paddle 222 when rotating is smaller than the distance between the master rotating shaft 212 and the slave rotating shaft 221.
Please refer to fig. 4, which is a schematic structural diagram of a main stirring paddle according to an embodiment of the present application. As shown in fig. 4, in other embodiments of the present invention, each blade of the master paddle 213 and/or the slave paddle 222 forms an angle α with the horizontal plane, and the angle α is preferably 15 degrees, so as to increase the contact area between the blade and the feed liquid, and further enhance the stirring strength.
