Abstract
An apparatus for adding trim water or liquid to a mixture in a powered mixer and controlling the amount automatically. After a selected temperature has been signalled by a temperature sensing device, the water or liquid is pulsed into the mixer, each pulse being followed by a dispersion time, until a selected power level is detected by a power sensing device, the selected power level having previously been correlated through testing with a desired characteristic of the mixture. When the selected power level is detected, a signal from the power sensing device terminates the water or liquid addition.
