At the same time, the motor is started, so that the cavity stirring blade rotates to stir, thereby maximizing the efficiency of mixing the nutrient solution and the fermentation liquid. This solves the problem that when the fermentation liquid is poured into the tank and then the nutrient solution is poured in, so that the nutrient solution is on top of the fermentation liquid, the simple rotation of the stirrer is generally not enough to quickly mix the nutrient solution and the fermentation liquid evenly, which may result in low stirring efficiency.

[0030] The specific settings and functions of the stirring component 2 and the scraping component 3 will be explained below.
[0031] Reference Figure 2 and Figure 4 as well as Figure 5 As shown, in this embodiment: the stirring assembly 2 includes a hollow rotating shaft 21 rotatably connected to the lower end of the cover 7. The hollow rotating shaft 21 is fixed to the output end of the motor 9. A hollow stirring blade 22 is fixedly connected to the arc surface of the hollow rotating shaft 21. Multiple evenly distributed water outlet pipes 29 are fixedly connected to the upper end of the hollow stirring blade 22. By setting the stirring assembly 2, when it is necessary to mix the nutrient solution into the fermentation liquid, the nutrient solution is input into the hollow rotating shaft 21 and the hollow stirring blade 22 through the water inlet mechanism, so that it flows out into the fermentation liquid through the water outlet pipes 29. At the same time, the motor 9 is started, so that the hollow stirring blade 22 rotates to stir, thereby maximizing the efficiency of uniform mixing of the nutrient solution and the fermentation liquid. A sealing cap 210 is provided on the inner wall of the water outlet pipe 29. A first spring 211 is fixedly connected to the lower end of the sealing cap 210. The other end of the first spring 211 is fixed to the hollow stirring blade 22. By setting the first spring 211, the sealing cap 210 is limited, maximizing the efficiency of uniform mixing. To prevent fermentation broth from entering the cavity stirring blade 22, when there is nutrient solution in the cavity stirring blade 22, the sealing cover 210 is pushed out, allowing it to flow into the fermentation broth. The cavity rotating shaft 21 is rotatably connected to a cavity rotating ring 23 on its arc surface. The inner arc surface of the cavity rotating ring 23 has a first water inlet hole 24, and the arc surface of the cavity rotating shaft 21 has a second water inlet hole 25. A self-priming pump 27 is installed at the upper end of the cover 7, and a short water supply is fixedly connected between the output end of the self-priming pump 27 and the cavity rotating ring 23. Pipe 26 and the input end of self-priming pump 27 are fixedly connected to connecting pipe 28. Connecting pipe 28 and external nutrient solution pipe are fixed. Self-priming pump 27 is started, and nutrient solution is introduced into cavity rotating shaft 21 through short water pipe 26, cavity rotating ring 23, first water inlet hole 24 and second water inlet hole 25. The lower end of sealing cover 210 is fixedly connected to telescopic rod 212. The other end of telescopic rod 212 is fixed to cavity stirring blade 22. The spring is limited by setting telescopic rod 212.
[0032] Reference Figure 2 and Figure 3As shown, in this embodiment: the scraping component 3 includes a mounting ring 31 disposed on the arc surface of the cavity rotating shaft 21. A scraper 32 is fixedly connected to the arc surface of the mounting ring 31. When fermentation liquid adhering to the bottom of the inner wall of the tank 1 is needed, the mounting ring 31 and the cavity rotating shaft 21 are fixed by a fixing mechanism, thereby rotating the cavity rotating shaft 21 and causing the scraper 32 to rotate, thereby scraping off the fermentation liquid adhering to the bottom of the inner wall of the tank 1. A plurality of evenly distributed pins 33 are slidably inserted into the arc surface of the cavity rotating shaft 21. The pins 33 are inserted into the mounting ring 31, locking the mounting ring 31 in place. The pin 33 is inserted into the mounting ring 31 by a pushing mechanism, thereby fixing the mounting ring 31 and the hollow shaft 21. A screw 36 is threaded into the lower end of the hollow shaft 21. A push rod 34 is fixedly connected to one end of the pin 33. The push rod 34 passes through the hollow shaft 21. Tightening the screw 36 will squeeze the push rod 34. A second spring 35 is fixedly connected to one end of the pin 33. The second spring 35 is fixed to the hollow shaft 21. By setting the second spring 35, the screw 36 is released from its limit, allowing the pin 33 to reset.
[0033] Working principle:
[0034] When adding nutrient solution during fermentation, workers pour the glutathione fermentation broth into the tank 1 supported by the support leg 4 through the feed pipe 8. After pouring the nutrient solution into the tank 1, the motor 9 on the cover 7 is started, causing the agitator to rotate and mix the nutrient solution and fermentation broth. After mixing, the valve 6 is opened, allowing the mixed liquid to flow out through the discharge pipe 5. When it is necessary to mix the nutrient solution into the fermentation broth, the connecting pipe 28 and the external nutrient solution pipe are fixed, and the self-priming pump 27 is started. The nutrient solution is fed into the cavity shaft 21 through the short water pipe 26, the cavity rotating ring 23, the first water inlet 24, and the second water inlet 25, thus entering the cavity rotating shaft 21. This feeds into the cavity rotating shaft 21 and the cavity stirring blades 22, allowing it to flow out into the fermentation broth through the outlet pipe 29. Simultaneously, the motor 9 is started, causing the cavity stirring blades 22 to rotate and stir, thereby maximizing the mixing effect. To improve the efficiency of mixing the nutrient solution and fermentation liquid, a first spring 211 is used to limit the sealing cap 210, preventing the fermentation liquid from entering the cavity stirring blade 22 as much as possible. When there is nutrient solution in the cavity stirring blade 22, the sealing cap 210 is pushed out, allowing it to flow into the fermentation liquid. A telescopic rod 212 is used to limit the spring. When the fermentation liquid adhering to the bottom of the inner wall of the tank 1 is needed, the mounting ring 31 is inserted into the cavity rotating shaft 21, and then the screw 36 is turned to squeeze the push rod 34, causing the pin 33 to engage with the mounting ring 31, thus fixing the mounting ring 31 and the cavity rotating shaft 21. The cavity rotating shaft 21 rotates, causing the scraper 32 to rotate, thereby scraping off the fermentation liquid adhering to the bottom of the inner wall of the tank 1. A second spring 35 is used to release the screw 36 limit, allowing the pin 33 to reset.
