Abstract

An improved veneer dryer and method for enhancing the performance of a veneer dryer. The veneer dryer includes at least one drying chamber (38) that includes conveyor for conveying product to be dried between an input end and an output end. A plurality of upper (54) and lower (52) nozzles are arranged above and below the conveyor and are operative to direct heated air (44) into an impinging contact with material being conveyed on the conveyor. The nozzles are arranged in pairs wherein one nozzle of a pair includes a plurality of discharge ports that are offset with respect to a plurality of discharge ports forming part of the other nozzle of the pair. The nozzles are preferably tapered in a longitudinal direction, such that the ratio of a cross section of an inlet end of the nozzle and the cross section of a terminal end of the nozzle is equal to or less than 7.5625 and greater than 5.04. The nozzles are arranged in pairs both in a lateral direction and a vertical direction. The extent to which the discharge ports of one nozzle are offset with respect to the discharge ports of the other nozzle is less than the lateral distance of adjacent discharge ports on a given nozzle.
