Abstract
Foodstuff is heated in a chamber ventilated by a fan through an exhaust duct. The duct has a sufficiently long airflow passage to produce a substantially laminar flow therein. An opening at an intermediate position along the duct length faces in a direction substantially perpendicular to the direction of the laminar airflow. The opening is closed by an enclosure so vaporized substance emitted by the foodstuff diffuses from the duct through the opening into the enclosure. A sensor in the enclosure detects the diffusing substance and develops a signal indicating a condition of the foodstuff.
