Abstract: A counter-top reheating unit for packages containing pre-cooked meals which are initially in a frozen state, the unit acting to quickly raise the temperature of the meals to a service temperature level and to maintain the meals at this level for an indefinite period. The unit includes a box-like case having telescoped therein an open-fronted inner box whose walls are spaced from those of the case to define rear and side air spaces therebetween. Mounted within the inner box is a compartment to receive a stack of packages with spacings therebetween. The perforated wall of the compartment is spaced from the rear of the inner box to define a rear plenum.
