Description

Technical Field

[0001] The utility model relates to a fermentation tank, in particular to a fermentation tank with uniform mixing, belonging to the technical field of fermentation tanks. Background Technique

[0002] Yogurt is a dairy product made from milk by adding a starter culture to the milk. It not only retains all the advantages of milk but is also easier to digest than milk. Therefore, yogurt is an extremely suitable nutritious drink. In the process of yogurt fermentation preparation, a special fermentation tank is required for yogurt fermentation.

[0003] In the prior art, as disclosed in a yogurt fermentation tank with the publication number CN218245469U, including a fermentation tank, a motor is fixedly connected to the top of the fermentation tank. One end of the output shaft of the motor passes through the top of the fermentation tank and is fixedly connected to a driving shaft. At least one stirring frame is fixedly connected to the circumference of the driving shaft; an installation cylinder is rotatably connected to the inner wall of the top of the fermentation tank. When scraping the yogurt on the inner wall of the fermentation tank, the arc-shaped scraping strip can shake under the action of the wedge-shaped block. Thus, when scraping the yogurt on the inner wall of the fermentation tank, it can also make the yogurt on the arc-shaped scraping strip fall off, reducing the waste of yogurt and quickly discharging the yogurt, improving the discharging efficiency. However, in actual use, although the existing fermentation tank can scrape the yogurt on the inner wall of the tank to ensure that when stirring and mixing the yogurt raw materials, the part of the raw materials adhered to the inner wall is not mixed unevenly, during the whole stirring and mixing process, it can only horizontally rotate and stir and mix the yogurt raw materials at multiple positions, and cannot turn the yogurt fermentation raw materials up and down. Although it can also ensure uniform mixing after a long time of stirring, due to the need for a long time of stirring, it will affect the fermentation efficiency. Secondly, during the yogurt fermentation process, the fermentation temperature needs to be maintained within a relatively constant range. As disclosed in a yogurt fermentation tank with the publication number CN211983575U, a heat preservation layer and a heating pipe are provided on the tank wall of the fermentation tank body, which can ensure constant-temperature yogurt fermentation and improve the product quality. However, since the heating pipe is arranged on the tank wall, for the yogurt fermentation raw materials, it can only be heated and insulated externally, and cannot be directly heated and insulated internally, which is likely to cause uneven temperature between the internal and external parts, that is, the overall heating and insulation effect is not ideal.

[0040] Furthermore, one end of the inner cavity partition plate 32 close to the inner cavity 21 of the rotating rod is integrally connected with a bent flow guide plate 33, and the bent flow guide plate 33 is arranged in the inner cavity 21 of the rotating rod in a downwardly bent shape. When warm water flows upward along the inner cavity 21 of the rotating rod, a part of the warm water can be guided into the inner cavity 31 of the stirring rod through the action of the bent flow guide plate 33.

[0041] Working principle: Various raw materials for yogurt preparation are added into the tank body 1 through the feed pipe 12. The driving motor 6 provides driving force to drive the rotating rod 2 to rotate in the tank body 1, and then drives the stirring rod 3 and the spiral stirring blade 5 to rotate accordingly, so as to realize the stirring and mixing of the raw materials for yogurt preparation placed in the tank body 1. And because the spiral stirring blade 5 can drive the raw materials for yogurt preparation to turn up and down during rotation, and the multiple stirring rods 3 can stir the raw materials for yogurt preparation in the tank at multiple positions, the mixing rate can be improved.
