A system for heating objects serially within a plurality of separate heating zones is described. Objects are placed on pallets and sequentially moved through the plurality of heating zones. In a preferred embodiment, the pallets are fabricated of a microwave absorptive material and sequentially moved through a plurality of microwave cavities. The microwave cavities are provided with a source of microwave energy which heats the pallets, and by conduction, the objects placed thereon.

A conveyorized heating system, comprising: a plurality of adjacent microwave cavities; a microwave radiating means for independently, selectively radiating microwave energy in each of said cavities; at least one pallet means for supporting an object to be heated; a conveyance means for transporting

A conveyorized heating system, comprising: a plurality of adjacent microwave cavities; a microwave radiating means for independently, selectively radiating microwave energy in each of said cavities; at least one pallet means for supporting an object to be heated; a conveyance means for transporting said at least one pallet means sequentially through said plurality of adjacent cavities; a selectively operable, microwave and environmentally sealing closure between adjacent pairs of said cavities, closing of said closure permitting independent and arbitrarily different environmental and microwave conditions within ones of said adjacent pair of cavities; and opening means, cooperating with said conveyance means, for selectively and time sequentially opening said closure to permit passage therethrough of said at least one pallet means, said at least one pallet means operably integral to said conveyance means, having conveyor loop means, is made of a microwave absorptive material, said microwave absorptive pallet means directly contacts a not highly microwave absorptive object to be heated thereon which is to be heated by conduction of heat from said microwave absorptive pallet means which is heated by said radiated microwave energy as said microwave absorptive pallet means is transported through each cavity.
