During the production process of fermented food, it is necessary to put the food raw materials into a fermentation container for sealing, and then ferment. Application number CN202020598683.6 discloses a fermentation tank for food processing, which relates to the field of food processing technology. The fermentation tank for food processing, by setting a turntable, a driving shaft, a limit frame, a tooth plate and a gear, achieves the effect of making the stirring structure rotate forward and reverse to fully stir the raw materials, and solves the problem that the current fermentation tank only stirs in one direction during the stirring process, the stirring efficiency is low, and the raw materials cannot be fully mixed and reacted. However, when the structure is actually used, the bottom of the rotating rod is not provided with a limit mechanism, which is easy to cause the rotating rod to shake when the rotating rod drives the stirring rod to stir, affecting the use effect.

[0003] The publication (announcement) number is CN219507909U, which discloses a fermentation tank that can be used for rapid fermentation of food, belonging to the technical field of fermentation tanks, including a fermentation tank body and a top cover arranged on the top of the fermentation tank body, an electric heating pipe is arranged in the middle of the bottom wall of the fermentation tank body, an electric box is arranged on one side of the middle of the bottom wall of the fermentation tank body, an equipment box is arranged on the top of the top cover, an air pump and a first motor are arranged in the middle of the equipment box, and a temperature sensor is arranged at the bottom of the top cover. The utility model firstly limits the bottom end of the rotating rod by the first rolling ball and the stirring rod, improves the stability of the rotating rod driving the stirring rod to rotate, improves the stirring effect, and can increase the food fermentation rate by stirring, and at the same time, the electric heating pipe can be controlled by the electric box to increase the temperature of the inside of the fermentation tank body, further increasing the food fermentation rate, and the pressure inside the fermentation tank body can be controlled by the cooperation of the air pump and the air pressure valve to improve the use effect.

[0004] Although the above scheme improves the sealing effect of the fermentation tank and the stability of the rotation of the stirring component, the sealing and opening of the fermentation tank requires the cooperation of components such as a motor, a gear ring, and multiple gears. The sealing and opening structure of the equipment tank is complex and the operating cost is high, and the heating effect of the fermentation raw materials is not sufficient. For this reason, we propose a fermentation tank that can be used for rapid fermentation of food. Utility Model Content
