Abstract
Pre-frozen complete dinners are packaged in a compartmented tray which is formed from a material transparent to microwave radiation of a frequency which would be employed to heat or partially cook the food. The tray, with the various foods of the dinner in separate compartments, is taken directly from a freezer storage and is placed in a specially designed shielding box which in turn is placed in a microwave oven to heat the food. Means are provided on the box to control the degree to which each tray compartment, and the food contained therein, is exposed to the radiation, thus controlling the degree of heating or cooking of each of the foods independently of each other. Means are provided for isolating each of the compartments fully from each other while the food is being heated to preclude contact between the separate foods and gases generated during the heating or cooking process. The shielding box is intended to be used repeatedly as in mass feeding environments and is adapted to enable repetitive insertion and removal of food bearing trays. Each tray is of the same configuration and means are provided to insure proper orientation of the trays in the shielding box. Means also are provided for supplementally shielding a selected of the tray compartments from stray internally reflected radiation.
