Evaluation of a rotating drum mixer

Abstract

A "rotating drum" type mixer was tested to determine if it could produce a uniformly mixed feed. Feed was manufactured in four separate trials, which examined addition sequence, mixing time, mixer capacity, and liquid addition. Uniformly mixed feed was obtained after 8 min, when ingredients were properly sequenced and mixed. Smaller batch sizes decreased the time required to obtain a uniform mixture. The mixer distributed liquid uniformly through the feed and had excellent clean-out capabilities.
