AI Technical Summary
In traditional microbial fermentation devices, the stirring shaft can only rely on one, and the internal raw materials and additives cannot be fully mixed, resulting in insufficient fermentation process.
A stirring tank for microbial fermentation is designed, and two stirring shafts (first stirring shaft and second stirring shaft) are connected by connecting pipes. The plug-in rod can be lifted and moved to open the orifice of the stirring shaft, so that the additives flow in and evenly mix them into the raw material.
Through the dual stirring shaft design, additives can be mixed uniformly into the raw materials, improving the adequacy and efficiency of the fermentation process.
