(54)	STAGED FRYER HEATING SYSTEM

(57) Systems, methods, and computer program products for controlling a heating system (40) in a fryer (10). At startup, a setpoint temperature (T_SP) for a cooking medium (36) is set to a melt temperature (T_MELT). While in melt mode, each of a plurality of heating elements (44-47) each located in a different region of a fry pot (12, 14) is sequentially activated to control an amount of heat provided to the cooking medium. Once the cooking medium has reached the melt temperature, the setpoint temperature is increased to a target cooking temperature (T_TCT). While in cooking mode, if an order to cook a food product is not received within a predetermined time period, the setpoint temperature is set to an idle temperature (T_IDLE) which is below the target setpoint temperature and above the melt temperature. The target cooking temperature is adjusted using a set of setpoint bias temperatures that is selected based on a cooking load.
