Abstract
A deep fat fryer includes an open-top vessel having at least one trough-shaped container adapted to hold a quantity of cooking oil. A pulse combustion burner is provided for heating the oil and includes a combustion chamber adapted to be immersed in the oil. A mixer head receives controllable air and fuel flows and an ignitor within the mixer head initiates combustion. A cabinet is provided for supporting the vessel and the burner. A tailpipe receives the combustion products and carries the same into an exhaust decoupler which is located adjacent the inlet end of the combustion chamber and which substantially enclosed the mixer head and at least a portion of a vent pipe. The exhaust decoupler and the tailpipe are arranged in heat exchange relationship with the vessel wall. A continuously operating air blower is provided to minimize burner start-up time and to cool electronic control circuitry used to regulate the oil temperature and the operating periods of the burner.
