[0002] During the fermentation process, bacteria, yeast and other microorganisms will carry out metabolic activities to produce carbon dioxide gas. These gases rise and gather in the liquid to form foam. Although foam is a common phenomenon in the fermentation process, excessive foam may hinder gas exchange and affect the growth and metabolism of microorganisms. Therefore, defoaming technology is needed to control the generation of foam during the fermentation process.

[0004] Existing microbial fermentation devices are prone to foaming during the fermentation process. The foam is generated in the fermentation tank. Since the fermentation tank requires a sterile environment, the fermentation tank cannot be opened at any time for defoaming operations, resulting in foam accumulation, affecting gas exchange and fermentation effects. Therefore, a fermentation defoaming device is proposed to address the above problems. Utility Model Content

[0024] Working principle: In the existing microbial fermentation device, foam is easily generated during the fermentation process. The foam is generated in the fermentation tank 1. Since the fermentation tank 1 requires a sterile environment, the fermentation tank 1 cannot be opened at any time for defoaming operation, which leads to the accumulation of foam, affecting the exchange of gas and the fermentation effect. Therefore, a fermentation defoaming device is proposed to solve the above problems. During the fermentation process, the positions of the first electrode plate 9 and the second electrode plate 13 are adjusted according to the amount of material in the fermentation tank 1, and the second fixing ring 11 is slid to move along the vertical rod 10, so that the second electrode plate 13 is also released. The first electrode plate 9 is moved until the distance between the first electrode plate 9 and the second electrode plate 13 meets the requirements, and the second fixing ring 11 is fixed by the first locking bolt 8, so that the initial position difference between the first electrode plate 9 and the second electrode plate 13 can be set according to the amount of fermentation material. When the initial position difference is adjusted, the first fixing ring 7 is moved along the foam rod 4, and the first electrode plate 9 is moved accordingly. As the fermentation proceeds, foam will be generated. As the foam increases, the foam frame 5 is lifted, thereby pushing the foam rod 4 upward. When the first electrode plate 9 moves up to contact the second electrode plate 13, the signal light 22 receives the signal. The signal light 22 model is AD16-25, and transmits the signal to the controller 21. The controller 21 model is STM32. The controller 21 starts the motor 16 and opens the solenoid valve 20, so that the defoamer in the storage barrel 18 is added to the fermentation tank 1 through the feeding pipe 19. At the same time, the motor 16 operates to make the gear 17 rotate. , with the cooperation of the teeth 14, the rotating disk 3 drives the foam frame 5 and the film 6 to rotate. When it reaches the position of the feeding tube 19, due to the obstruction of the feeding tube 19, the rotating disk 3 drives the foam frame 5 and the film 6 to rotate counterclockwise, so that the motor 16 performs forward and reverse exchange operations, and then drives the foam frame 5 and the film 6 to perform forward and reverse movements, so that the foam can be flattened and fully contacted with the defoaming agent, so that it can not only automatically identify the rise of foam, but also automatically perform defoaming operations, while improving the defoaming effect, avoiding foam accumulation, and ensuring the fermentation effect.
