Abstract
An induction heatable body ( ) that quickly heats to a desired temperature, retains heat long enough to be used in almost any application, and develops no “hot spots” even when heated by a heating source having an uneven magnetic field distribution. The induction-heatable body ( ) achieves the foregoing while remaining relatively lightweight, inexpensive and easy to manufacture. The induction-heatable body ( ) includes a plurality of induction-heatable layers ( ) each sandwiched between alternating layers of heat retentive material ( ). The induction-heatable layers ( ) consist of sheets of graphite material that can be inductively heated at magnetic field frequencies between 20 and 50 kHz. The heat-retentive layers ( ) consist of solid-to-solid phase change material such as radiation cross-linked polyethylene. A food delivery assembly ( ) uniquely adapted and configured for maintaining the temperature of sandwiches, french fries, and other related food items is also disclosed. The food delivery assembly ( ) includes a magnetic induction heater ( ), a food container ( ), and a delivery bag ( ) for carrying and insulating the food container ( ).
