Abstract

See full text

A method for operating an agitating device and a digester, wherein the digester is filled with a substrate and an agitating device is in the digester. These steps are performed: a) A target load curve is lodged in the control device; b) the control device prescribes a target rotation speed; c) the control device operates the agitating device at an actual speed corresponding to a target speed; d) the control device captures an actual agitating device torque measurement value at the actual speed of rotation; e) the control device derives from the actual measurement value an actual characteristic value of the agitating device applied torque; f) the control device compares the derived actual characteristic value against the target characteristic value of the substrate resulting from the target load curve at the prescribed target speed; and g) the control device controls the agitating device in dependence on the result of comparison.
