ABSTRACT:
A fryer system having a vat containing shortening, a first heater for supplying heat to the shortening, and a second heater for supplying heat to the shortening. The second heater is preferably activated only when the temperature of the shortening falls below a predetermined minimum temperature and disabled when the temperature of the shortening reaches a predetermined maximum temperature. In one preferred embodiment, the first heater is a heat exchanger with a gas burner while the second heater is an electric heating element. In another preferred embodiment, the first heater is an electric heating element and the second heater is an autotransformer supplying an overvoltage to the electric heating element. A method for operating a heating system for a fryer is also disclosed.
