Abstract
A substantially enclosed and insulated frame has a chain conveyor for carrying patties from one end of the frame to the other. A motor on the frame operates the chain conveyor. A heating element on the frame is effective to increase the temperature within the enclosure and is in position to heat a patty on the conveyor. A thermostat on the frame within the enclosure is subject to such temperature and is effective through a controller to vary the speed of the conveyor in relation to the temperature of the thermostat. Preferably, the speed of advance of the conveyor is increased as the enclosure temperature increases and vice versa. A manual controller permits variation in the ratio of the sensed temperature and the speed of the conveyor.
