Abstract
Apparatus to transfer heat to the surface of a product includes a product support, a duct having a duct entrance, a duct outlet and a longitudinal duct axis and a plenum for delivering temperature controlled fluid into the entrance of the duct such that fluid flows longitudinally of the duct toward the outlet. A perforated plate has at least one orifice, having an orifice axis extending generally toward a product support for forming a jet of fluid, having a jet axis, flowing in a predetermined direction. The longitudinal duct axis of the duct is rotated relative to the orifice axis for changing the direction of the jet axis relative to the orifice axis for moving the jet axis relative to the product support.
