Technical Field

The utility model relates to the technical field of biological fermentation, in particular to a full-automatic acidity control device for microbial fermentation feed.

Background

The optimum pH range for microbial fermentation is generally between 5 and 8, for example, the optimum pH for glutamic acid fermentation is 7.5 to 8.0. However, the pH value of the fermentation varies with the species and the product. Because fermentation is a multi-enzyme composite reaction system, the optimal pH value of each enzyme is different, so that the optimal pH value for growth of the same strain is possibly different from the optimal pH value for product synthesis. Therefore, different pH ranges should be controlled at different stages of the fermentation process to maximize product yield.

In the process of biological fermentation, the pH value of fermentation liquor in a fermentation tank needs to be detected in real time, so that the condition that internal microorganisms cannot grow due to the imbalance of the pH value in the fermentation liquor is avoided. In the prior art, the pH value inside the metal can is measured mainly by adopting a mode of manual test paper detection, and then the pH value inside the metal can is adjusted by manually adding water and acid.
