Abstract
A fermentation controller correctly controls fermentation and produces a required material by fermentation. The fermentation controller (3) controls fermentation in a material production unit (1) that produces a material by fermentation. The controller (3) includes a capacitance sensor (63) to detect a capacitance change representative of a fermenting state in the material production unit and a memory (77) to store a reference capacitance change representative of a reference fermenting state. The controller compares the detected capacitance change with the reference capacitance change and controls fermentation in the material production unit according to the comparison result.
