A vending system for hot food comprises stacks of food-containing trays of a standard size, a microwave oven whose horizontal dimensions are similar to those of the trays and whose vertical dimension is preferably such as to produce a resonant cavity for the wavelength used, and means for feeding a selected one of the trays into the microwave oven on demand. The radiation is preferably introduced through a waveguide into the top of the tray. Each tray preferably carries heating instructions in machine readable code, e.g. as apertures on lateral extensions of a horizontal flange, and a reading head reads the instructions and adjusts the microwave oven accordingly. The stacks of trays may be held in a rotary magazine and selected by push-buttons.

A vending system for dispensing containers of hot food, comprising: a plurality of stacks of food-containing trays containing a corresponding number of different varieties of food, each tray carrying machine readable heating instructions on a lateral extension of a horizontal flange extending outward from an upwardly extending wall of the tray; a microwave oven whose horizontal dimensions are those of the trays and exceed them only by up to 10 mm, the vertical dimension of the microwave oven to ensure that a resonant cavity, bounded by one of the trays, is produced for microwave radiation of the wavelength used; a reading head adapted to read the heating instructions and to supply a corresponding control signal to the microwave oven; and means for feeding one of said trays into the microwave oven on demand.
