Abstract

Abstract A waste sterilizing and crushing apparatus includes a heating chamber adapted to receive wastes therein, and a heater for heating the interior of the heating chamber. The bottom of the heating chamber is formed with a discharge port, and a cover plate driven by a driving device to open and close the discharge port. A crusher is disposed below the heating chamber for crushing wastes, and a feeder is provided whereby wastes discharged through the discharge port are fed into the crusher. When the wastes are heated in the heating chamber, the discharge port is opened by the action of the cover plate. Thereupon, the wastes in the heating chamber are charged into the crusher through the discharge port and feeder.
