ABSTRACT:
A food cooking and heating cabinet having a closed air convection system consisting of a variable speed blower in a air heating chamber for circulating air past a variable heating element, through a food holding oven, and back to the air heating chamber, a control for selecting a desired temperature to be maintained in the food holding oven, and means for comparing the temperature at the outlet and the inlet of the heating chamber to the selected temperature causing the air variable heating element to operate and the speed of the blower to increase when more heat is required and reduces both heat and blower speed as the need for the higher heat and air flow is no longer required, and when preset parameters are reached automatically sets the temperature to a preset temperature and holds the heated product to the predetermined temperature.
