A domestic waste dryer which performs separating and sorting operations easily and efficiently in a subsequent process by drying the domestic waste before separating and sorting ordinary domestic waste is provided. A domestic waste dryer comprises: a frame(10) for forming an overall framework of the dryer; a cylindrically structured external cylinder(20) rotatably supported to the frame; an internal cylinder(30) which has a domestic waste injection port(31) formed on a front portion thereof and a discharge port(32) formed on a rear portion thereof, which is positioned in a central part of the external cylinder, and which is fixed to an inner wall of the external cylinder by a plurality of connecting bars(33) such that the injection port is projected from the external cylinder, the discharge port is spaced from the external cylinder, and the internal cylinder is rotated together with the external cylinder; an internal spiral pipe(40) adhered to an inner surface of the internal cylinder to transfer domestic waste injected into the internal cylinder toward the discharge port; an external spiral pipe(50) adhered to an outer surface of the internal cylinder to transfer domestic waste dropped through a discharge port(110) of the internal cylinder toward the discharge port formed on a front portion of the external cylinder; a heat supply pipe(60) extending to an outer side of the external cylinder to supply external heat into the internal and external spiral pipes; and a power device(70) for driving rotation of the external cylinder. |
