TECHNICAL FIELD
[0001] The utility model relates to yogurt fermentation technical field, concretely is a yogurt fermentation device. BACKGROUND
[0002] Yogurt fermentation is a biochemical process that uses lactic acid bacteria to convert lactose in milk into lactic acid. This process not only changes the pH of the milk, but also causes the proteins to coagulate, resulting in the unique texture of yogurt. In making yogurt, two types of lactic acid bacteria, Streptococcus thermophilus and Lactobacillus bulgaricus, are commonly used as starter cultures. These two strains can interact with each other to promote the fermentation of milk. Yogurt fermentation device is a special industrial equipment for producing yogurt. Its basic functions include heating, constant temperature control, stirring, cooling and fermentation. These functions ensure the smooth progress of the fermentation process under suitable temperature and conditions, thereby producing yogurt products with delicate taste and high nutritional value.
[0003] The common yogurt fermentation device is composed of a kettle body, a heating mechanism and a stirring mechanism. When in use, yogurt is poured into the kettle body, and then heated and stirred by the heating mechanism and the stirring mechanism to accelerate the fermentation process of the yogurt, reduce the stirring blind area and ensure that all raw materials can participate in the fermentation.
[0004] However, this method has some drawbacks. The kettle body is vertical in structure, and the stirring mechanism is installed in the middle of the inner cavity of the kettle body. Therefore, only simple circumferential stirring can be performed when stirring the yogurt. Due to the viscous texture of the yogurt, the mixing speed of the upper and lower layers of the yogurt during fermentation is slow, which is insufficient to promote the full mixing of the materials, especially in the early stage of fermentation. In addition, the heating is conducted by the bottom heating and temperature conduction method, and the vertical stirring makes the upper layer of yogurt warm up slowly, resulting in temperature difference and affecting the quality of yogurt fermentation. Therefore, a yogurt fermentation device is proposed. SUMMARY
