Abstract
Abstract An improved nozzle apparatus for convection ovens comprises a honeycomb material layer adapted as the discharge face of a fluid supply plenum to thereby provide a multiplicity of elongated passages or nozzles for directing fluid flow onto products moving through the oven; the fluid flow therefrom being exclusively perpendicular to the direction of product movement. A perforated plate is positioned on the discharge side of the honeycomb material layer to provide desired fluid distribution and flow velocity.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
Apparatus for heat treating a series of thin walled container products comprising, in combination: A. a conveyor for moving products through said apparatus; B. a supply plenum for heat treating fluid; C. a discharge face for said plenum arranged in a plane parallel to the plane of the conveyor and in closely spaced relation to the products moving on said conveyor, said discharge face including 1. a layer of honeycomb material having a plurality of interconnected wall members providing a multiplicity of adjacent, elongated vertically oriented defining a plurality of relatively small nozzles effective to direct fluid flow in a direction normal to the plane of the conveyor for impingement in a non turbulent manner on the products moving therepast.
Claim 2
Dependent Claim
