Abstract
An oven compartment in an oven for subjecting items to a selected heating sequence having a compartment container with a transport opening therein to permit selectively entering such items adjacent to first plenum structure at a perforated surface to allow providing heating fluid thereon. The first plenum structure has a material mass and a specific heat such that a rate of change of temperature of that structure exceeds one degree Centigrade per second for a selected maximum temperature differential between heating fluid and any entered items positioned adjacent to the perforated surface at selected heating fluid pressures at that perforated surface. A method for heating such items with a heating fluid previously heated by a heater, to an extent determined by operating a heater control, directed onto such items is based on obtaining a control representation of a selected set of values for the heater control versus time based on a heating specification for a selected kind of item to be heated. Heating fluid is directed onto such an item with this heating fluid having been previously heated by the heater through operating the heater control to follow the control representation but as adjusted based on measurements of heating fluid near the perforated surface.
