[0042] AsFigure 1 The embodiment shown provides a yogurt tank, which comprises a tank body, a stirring unit, a cleaning unit 3 and a feeding and draining unit.

[0043] Referring to Figure 1 The tank body comprises, from the inside to the outside, an inner container 11, an inner shell 12, a middle shell 13 and an outer shell 14, a circulating liquid path is formed between the inner shell 12 and the inner container 11, the circulating liquid path is used for introducing a thermal management medium, a containing interlayer is formed between the middle shell 13 and the inner shell 12, the containing interlayer is used for containing pipelines, and the containing interlayer is filled with thermal insulation materials; the stirring unit comprises a stirring paddle 21, which is rotatably arranged in the inner container 11 about its own axis; the cleaning unit 3 comprises a cleaning water inlet pipe 31 and a first valve assembly 32, one end of the cleaning water inlet pipe 31 is communicated with the inner container 11, the other end is communicated with a water supply device, and the first valve assembly 32 is used for controlling the opening and closing of the cleaning water inlet pipe 31 and the inner container 11; the feeding and draining unit comprises a feeding and draining pipe 41, which is used for introducing raw materials for making yogurt and draining cleaning water in the inner container 11.

[0044] The yogurt tank 100 provided by the embodiment can introduce raw materials for making yogurt into the inner container 11 through the feeding and draining pipe 41, without opening the inner container 11 and manually adding raw materials into the inner container 11. By arranging the cleaning water inlet pipe 31 and the first valve assembly 32, when cleaning the inner container 11, the first valve assembly 32 is opened, the cleaning water in the water supply device can enter the inner container 11 through the cleaning water inlet pipe 31, the inner container 11 is cleaned under the action of the stirring unit, the cleaned water is drained through the feeding and draining pipe 41, and the yogurt tank 100 is intelligent and highly automated. Moreover, the circulating liquid path formed between the inner container 11 and the inner shell 12 can introduce the thermal management medium, so that the outer side of the inner container 11 is uniformly covered with the thermal management medium instead of being heated locally, thereby improving the temperature uniformity of the inner container 11. Further, the containing interlayer formed between the inner shell 12 and the middle shell 13 is filled with thermal insulation materials, which can provide good thermal insulation effect for the inner container 11. The containing interlayer is also used for arranging various pipelines, thereby improving the integration of the device and realizing the miniaturized design of the yogurt tank 100.
