Frozen food in packs, generally of rectilinear configuration, are heated for consumption by being passed through a microwave energy field which generates heat which is substantially uniform across the pack width and which traverses the pack length due to movement relatively between the pack and microwave energy source. The relative movement overcomes thermal runaway since the energy is continuously being dragged away from the zones which have just been heated and where thermal runaway could otherwise occur. |
