Abstract: A method and an apparatus for simply disposing medical waste from a medical institution on site. The method comprises crushing medical waste in a closed container, exhausting air out of the container, sterilizing the air before releasing it into the atmosphere, and filling the container with a high-pressure steam having a temperature between 110.degree. C. and 150.degree. C. to sterilize the crushed medical waste. The apparatus is equipped with a pressure container having at least one air-tight seal, an internal waste crushing mechanism such as blades, an internal supply of steam, a valve for exhausting air from the container, and an air sterilizer for the exhausted air.

Abstract: Apparatus for sterilizing packed foods includes a sterilizing chamber for storing packed foods therein, a jet pipe mounted onthe interior upper portion of the sterilizing chamber for jetting mixture of steam and compressed air, an ejector having an inlet port, a suction port and an outlet port and connected at the outlet port to the jet pipe for generating a suction force through a flow of mixture of steam and compressed air, a steam line connected to the inlet port of the ejector for supplying steam thereto, a circulation line connected at one end to the interior lower portion of the sterilizing chamber and at the other end to the suction part of the ejector, a drain line connected to the bottom of the sterilizing chamber for exhausting a part of the mixture of steam and compressed air, a heat exchanger interposed between the sterilizing chamber and the drain line, and a compressed air line connected to the inlet port of the ejector through the heat exchanger.
