Beschreibung
Zusammenfassung:	A system is provided for heating batches of sealed, metal cans containing a food product. The system includes a pressure chamber, an induction coil, a can support, a sealing device, a power supply, an air pressure source, and a drive. The pressure chamber has an opening. The induction coil is supported within the pressure chamber. The can support is for engaging and rotating a plurality of sealed, metal cans, at least a portion of the can support being movable through the opening from a first position outside of the chamber to a second position within the chamber adjacent to the induction coil and being rotatably supported within the chamber. The sealing device seals the pressure chamber when the can support is within the chamber. The power supply is coupled to the induction coil to energize the coil to apply an alternating current to the coil to induce a current into the metal cans which heats the food product of the metal cans. The air pressure source is coupled to the pressure chamber to pressurize the chamber during energization of the induction coil. The drive is coupled to the can support which rotates the can support during energization of the induction coil.
