Abstract
An oven employing electromagnetic radiation as a source of heat is adapted for use in the mass preparation of complete pre-frozen or refrigerated meals such as in institutional feeding environments and the like. Each meal is prepackaged and contained in a single radiation transparent tray with the various individual foods of the meal being located in selected predetermined compartments of the tray. The oven includes a lower conveyor belt which carries the tray through the oven and an upper conveyor belt which moves through the oven at the same linear speed as the lower conveyor belt but spaced above the lower belt so that the tray may be received and disposed between the belts. Each of the upper and lower belts include means defining radiation transparent apertures arranged in a predetermined array to be alignable with the different compartments in each food tray. The apertures are arranged to control the amount of radiation to which each food in each tray is exposed. The belts and the trays move in unison through the oven at a predetermined rate which is controlled in relation to the degree of energy radiated within the oven so that each of the foods receive, selectively, energy sufficient to properly heat condition them. At the outlet end of the oven, the belts separate and enable the heat conditioned dinner to be removed.
