Description

Technical Field

[0001] The utility model mainly relates to the technical field of lactic acid bacteria fermentation, and in particular to a lactic acid bacteria fermentation and cultivation device. Background Art

[0002] When producing some snack products such as yogurt, the high-temperature boiled and sterilized milk needs to be cooled to 40°C, lactic acid bacteria are mixed into the milk, and preliminary fermentation is carried out at 40°C. After the preliminary fermentation, the milk needs to be transferred to a 4°C environment for post-fermentation.

[0003] An existing patent (publication number: CN218860702U) discloses a lactic acid bacteria fermentation incubator with uniform heating. The incubator comprises an incubator housing, a first annular electric heating tube mounted within the side walls of the housing, and multiple support legs mounted at the bottom. The top of the incubator is movably connected to an upper cover, the center of which is provided with a motor cover. A motor slot is provided at the bottom of the motor cover, and a drive motor is mounted within the motor slot. The output shaft of the drive motor is connected to a stirring mechanism comprising a cylindrical connecting column. The present invention incorporates a stirring mechanism within the incubator to mix and stir the solution within the incubator for uniform mixing. Furthermore, a second electric heating tube within the stirring arm heats the mixed solution within the incubator and slowly stirs the solution as needed, ensuring uniform heating of the solution within the incubator, which is beneficial for the fermentation of probiotics.

[0004] In the process of implementing this solution, the inventor found that some impurities in the solution after fermentation treatment were adhered to the structure inside the kettle body in actual production. In the current technology, an electric push rod is used to open the upper cover. When workers are maintaining and cleaning the interior of the kettle body and the upper structure of the upper cover, the structure assembled on the upper cover is above the workers, which poses a great operational safety risk.
