It is known from Forrer U.S. Pat. No. 2,864,932 of Dec. 16, 1958 that food when wrapped in a suitable transparent film can be cooked when exposed to an infrared heat source and enclosed in an oven with space for free circulation of air by convection. In Barrett et al U.S. Pat. No. 3,108,173 of Oct. 22, 1963 the infrared heating apparatus is adapted for broiling food items, and has its housing provided with expanded sheet metal panels for the free circulation of air or observation of the progress being made on heating the food items, and in addition, there is provided conventional electrical controls including timer means for broiling. An infrared oven for heating packaged frozen food is disclosed by King U.S. Pat.
