Abstract: A deep fat frying system comprising an open ended frying chamber having a plurality of side walls, a floor portion for defining the basic frying chamber. There is further incorporated a heating system which would comprise an intake fan for intaking air, a gas inlet line, and an ignition zone for igniting the gas as the air is blown through the heating system. The heating system would further include a pair of flow channels which would be in spaced apart relation and directed in a modified "S" fashion through the frying chambers so that there are a plurality of right angle turns within the heating chambers prior to the heated air reaching the exit point at the rear end of the chamber. The angulated configuration of the double hot air flow channels would achieve a greater time within the hot oil that the heat is radiated outwardly into the oil and therefore less heat would escape and be lost to the back through the exiting point of the flow channels.
