Technical Field

[0001] The utility model belongs to the field of yogurt production, in particular to a fermentation tank for yogurt production. Background Art

[0002] Lactic acid beverages can be divided into two types: fermented and blended. Lactic acid bacteria beverages are made from milk fermented with lactic acid bacteria, and are fermented lactic acid beverages. Other lactic acid beverages are blended products, which are made from milk, water, sugar, citric acid or lactic acid. They are not fermented, and there are no lactic acid bacteria or metabolites of lactic acid bacteria in the products. At present, in the production process of yogurt beverages, the raw materials need to be fermented.

[0003] In the prior art, when yogurt is fermented, a single stirring blade is generally used to stir the yogurt in the fermentation tank, and an electric heating tube is arranged to heat the raw materials in the tank body to achieve fermentation. At the same time, the stirring of the stirring blade can ventilate the raw materials in the tank, thereby ensuring the oxygen supply required for the reproduction of beneficial bacteria in the raw materials. However, in the existing fermentation tank, the heating tube is generally only arranged on one side of the tank body, and the single stirring blade cannot achieve uniform stirring of the raw materials, which not only affects the fermentation efficiency of the yogurt, but also causes uneven heating of the yogurt, affecting the fermentation quality. In addition, the ventilation effect only through stirring is poor, and it is difficult to ensure the fermentation efficiency of the yogurt, which leads to a decrease in the yield of yogurt.
