ABSTRACT:
In induction-based food warming and serving system includes a table unit adapted for receiving seating around a perimeter thereof. A top surface of the table is divided into a plurality of serving areas, displaced about the perimeter. Each serving area includes a recessed portion for receiving an induction heater/warmer module, or in the alternative, a non-functional module. Each induction heating module defines a recess, below which is placed a high-frequency induction heat coil. The recess surrounds an insulative pad, which in turn receives a serving plate comprised of iron. The table unit, and in each induction module, includes a switch for concurrently or individually controlling each heating unit.
