Abstract
An apparatus for transferring thermal energy between a temperature-controlled fluid and products to be treated comprises a tunnel having a plurality of openings through which extend duct members for supplying said tunnel with a temperature-controlled fluid from a supply plenum. A perforated metal conveyor belt within said tunnel is driven by a variable speed drive and supports the product to be treated. A return plenum is positioned between the supply plenum and the tunnel and communicates with the tunnel through the plurality of openings. Means to circulate the temperature-controlled fluid forces the fluid through the duct members which collimate the fluid and discharge it in the form of high-velocity jets against the product. The jets break up the boundary layer around the product to facilitate heat transfer and the fluid rebounds through the openings through which the ducts project into a return plenum without producing laminar flow across the treated product.
