[0037] Working principle: Opening the pressure pump 16 allows the fermentation liquid in the sealed box 1 to be discharged into the cooling tank 4 through the nozzle 21. Then, the first cover 3 is placed on top to seal and cool the tank. When the nozzle 21 needs to be replaced, rotating the threaded tube 19 and the nozzle 21 allows the threaded tube 19 to gradually disengage from the second channel 18. At this time, under the elastic force of the first spring 23, the sealing plug 20 is pushed downwards. When the threaded tube 19 is completely disengaged from the second channel 18, the first spring 23 completely pushes down the sealing plug 20, thereby sealing the bottom center of the second channel 18. The fermentation liquid is blocked to prevent it from spilling. When it is necessary to check whether cooling is complete, only the pH value of the fermentation liquid needs to be checked. Open the first pipe valve 5 and let a small amount of fermentation liquid drip through the first row pipe 6 onto the pH test paper 11. Then observe the color change. If cooling is not complete, pull the top rod 25. The top rod 25 presses the second spring 24 and moves along the sleeve 7, thereby detaching the top rod 25 from the top plate 10. The top plate 10 and pH test paper 11 can then be removed and replaced. After replacing the pH test paper 11, wait a while for it to cool down, and then continue the test.
