Abstract:
1. A steam cooker comprising: a steam generator including a steam superheater having a first passageway in communication with the heat exchanger to receive hot gases from the heat exchanger and a second passageway in communication with the heating chamber to receive steam from the heating chamber, the first and second passageways arranged in a heat exchange relationship; wherein, in use, steam generated in the heating chamber travels along the second passageway while hot gases travel along the first passageway to superheat steam in the second passageway, the hot gases and the steam travel in a counter flow arrangement along the first and second passageways; and a steam cooking chamber in communication with the second passageway to receive superheated steam from the second passageway; wherein the first passageway comprises an exhaust conduit in communication with the heat exchanger and the second passageway comprises a steam conduit in communication with the heating chamber; wherein the exhaust conduit is disposed in the steam conduit, the second passageway defined between the steam conduit and the exhaust conduit; wherein pressure in the heating chamber is at least about three psi while steam is being generated therein; wherein steam traveling along the second passageway is heated to a temperature of between about 220 degrees F. and 260 degrees F.
