Abstract: Apparatus for heating, disinfecting and sterilizing materials through exposure to microwave radiation; includes a treatment chamber which houses a container filled with material to be treated. An injector is in fluid communication with the container for introducing a liquid to the material and includes a dome which is tightly placed on top of the container, and a nozzle which is secured interiorly of the dome and projects through an opening of the container for injecting liquid into the treatment chamber. An exhaust conduit further projects into the dome for discharge of exhaust fluid from within the container directly to an area outside of the treatment chamber.

Abstract: Apparatus for heating and thermal decontaminating, e.g. sterilizing, pasteurizing and/or disinfecting, pumpable or pourable material, includes a microwave unit forming a treatment chamber for receiving the material transported along a passageway and for subjecting the material to microwave radiation. Two pumps are respectively situated upstream and downstream of the treatment chamber, with a pressure sensor being arranged between the pumps for generating a a signal commensurate with the pressure in the passageway between the pumps. The signal is transmitted from the pressure sensor to a control unit which is operatively connected to both pumps.
