AI Technical Summary

Technical Problem

Existing natto fermentation equipment cannot control the discharge rate during the discharge process, which may lead to equipment blockage and shutdown.

Method used

The discharge speed is adjusted by controlling the size of the through hole by using a limit rod and gear transmission system inside the fermentation tank, and anti-clogging guide blades are installed in the discharge hopper to prevent material from adhering and clogging.

Benefits of technology

This achieves controllability of the discharge speed, avoids equipment blockage, and ensures the continuous stability of the discharge process and the uniformity of fermentation quality.
