ABSTRACT:
A device for applying heat to sludge, including a rotating tubular chamber having a hollow-centered helical auger on its interior to move the sludge longitudinally through the chamber, and a gas distribution tube extending through the center of the chamber. Hot gas is injected into the chamber through outlets in the wall of the distribution tube, and sludge, which has been raised by lifters on the interior of the rotating chamber, falls through the hot gas streams from the outlets to dry and pasteurize the sludge. Chambers may be used in series, with the discharge from one chamber feeding the inlet of the next.
