Abstract
A steam cooker includes a steam generator including a heating chamber defining a volume for holding water. A heat exchanger is associated with the heating chamber so as to generate steam. A steam superheater superheats steam traveling from the heating chamber to a steam cooking chamber.
Claims24
A steam cooker comprising:
- a steam generator including
- a heating chamber defining a volume for holding water;
- a heat exchanger associated with the heating chamber, the heat exchanger configured to have hot gases pass therethrough in order to heat water in the heating chamber so as to generate steam;
- and
- 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;
- and
- a steam cooking chamber in communication with the second passageway to receive superheated steam from the second passageway.

- a heat exchanger associated with the heating chamber, the heat exchanger configured to have hot gases pass therethrough in order to heat water in the heating chamber so as to generate steam;
- an exhaust stack arranged to receive hot gases from the heat exchanger;
- and
- a steam flow path that receives steam from the heating chamber, the steam flow path arranged in a heat exchange relationship with the exhaust stack such that, in use, steam moving along the steam flow path is superheated by heat from hot gases traveling along the exhaust stack;
- and
- a steam cooking chamber for receiving superheated steam from the steam flow path.

A method of cooking using superheated steam, the method comprising:
- generating steam from water disposed in a boiler comprising a heating chamber and a heat exchanger disposed in the heating chamber where hot gases pass through the heat exchanger;
- superheating the steam in a superheater having a first passageway in communication with the heat exchanger for receiving hot gases and a second passageway in communication with the heating chamber for receiving steam, the first and second passageways being in thermal communication such that steam traveling from the heating chamber along the second passageway is superheated by hot gases traveling from the heat exchanger along the first passageway;
- and introducing superheated steam to a cooking chamber.
A steam cooker comprising:
- a steam generator including a heating chamber defining a volume for holding water and an on-board heat exchanger associated with the heating chamber;
- a steam path in communication with the heating chamber to receive steam from the heating chamber and extending to a steam cooking chamber;
- an on-board heating mechanism located along the steam path for superheating steam traveling along the steam path to a temperature of between about 220 and 260 degrees F.
