According to the pH test results, it is tested once every 24 hours and an appropriate amount of acidic substance is gradually added to ensure that the pH value is stable.

[0058] Finally, the material is transported from the discharge hopper 105 of the second fermentation tank 2 to the feed port 103 of the third fermentation tank 3 through a screw conveyor 701. The structure of the third fermentation tank 3 is the same as that of the previous two fermentation tanks.
