Claims16
A deep fryer, comprising:
- a fry tank for holding a cooking medium, the fry tank comprising:
- a cooking zone;
- and
- a lower chamber located beneath the cooking zone, the lower chamber comprising:
- a front wall and a back wall;
- and
- a right side wall and a left side wall;
- and
- a combustion system comprising:
- at least one gas supply conduit for receiving and distributing a combustion gas;
- at least one burner in fluid communication with the at least one gas supply conduit;
- at least two generally horizontal combustion chambers, each combustion chamber being in fluid communication with a corresponding burner, each combustion chamber being affixed to an exterior surface of one of the right side wall or the left side wall of the lower chamber, so as to be in heat transfer communication with the exterior surface of such side wall, wherein the right side wall and the left wall form interior walls of the combustion chambers;
- at least one flue in fluid communication with each combustion chamber for exhausting the combustion gas;
- and
- wherein each combustion chamber comprises:
- an inlet portion located near the front wall of the lower chamber;
- and
- an outlet portion located near the back wall of the lower chamber;
- wherein the combustion gas flows continuously in a generally horizontally orientation along the right side wall and the left side wall of the lower chamber from the inlet portion to the outlet portion and thereafter is exhausted through the flue.
