Claim:
A roller grill assembly, comprising: a housing; a plurality of roller tubes, each roller tube rotatably mounted to the housing, wherein each of the plurality of roller tubes is substantially hollow and defines a first opening at a first end of the roller tube and a second opening at the second end of the roller tube, and wherein each of the plurality of roller tubes includes a heating element for heating a surface of the roller tube; a first restrictor positioned orthogonal to a first opening at a first end of the roller tube, the first restrictor substantially covering each of the first ends of the plurality of roller tubes, wherein the first restrictor does not contact the first ends of the plurality of roller tubes; wherein the first restrictor creates a convective air stream within each of the roller tubes when the heating element is activated; and a plurality of temperature measuring probes located within the hollow portion of at least one roller tube of the roller grill assembly to measure the temperature of the convective air stream within the associated roller tube.
