Abstract
Apparatus for thawing and reheating a deep-frozen food preparation by microwave and infrared radiation comprises a housing enclosing a heating chamber which is delimited by a tubular wall. The chamber is subjected to microwave radiation from two inlets as well as infrared radiation. The inlets of microwave radiation are arranged in two opposed regions of the tubular wall situated on either side of the central region where the food product is positioned, and the infrared heating elements comprise at least two lamps extending axially of the tubular wall and arranged on either side of the central region in two opposed regions distinct from those of the wave guide openings. A heating process performed using this apparatus involves simultaneously producing continuous microwave radiation by alternately feeding two generators branched in anti-parallel, and continuous infrared radiation, throughout a thawing and reheating cycle.
