ABSTRACT:
Heating devices and methods which are particularly useful in vending machines for hot Foods. Foods such as beverages contained in individual containers such as cans are rapidly heated to serving temperature by induction heating for delivery to a customer. Various types of foods with food by varying the power and timing of the inductive heating. The type of food is identified by machine-readable indicia on the container which are automatically scanned prior to heating. The food containers may be agitated before, during and/or after heating to mix the contents and distribute heat evenly. The containers are heated in a vertical orientation to safely heat the food without overheating or damage to the container. A power management protocol turns off non-essential components of the vending machine while the inductive heater is energized to permit the vending machine to operate on a standard 120 VAC, 15 A electrical circuit without overload.
