Abstract
Shown is a baking oven or other gas treating apparatus having a novel gas distribution-box construction for circulation or impingement of a gaseous treating medium around or against goods conducted through the apparatus. The present invention is particularly applicable to the baking of baked goods, but also is applicable to the drying or treating of particulate material or webs of material and has other uses.
Claims9
In a longitudinally extending gas treating apparatus including longitudinally moving carrying means for transporting goods to be gas treated through said apparatus, the improvement comprising a gas distribution box for dispensing a gaseous medium in said apparatus, said distribution box comprising
- at least one plenum chamber having a longitudinal dimension and a transverse dimension, the plenum chamber longitudinal dimension extending laterally within the gas treating apparatus across the width of the goods being treated;
- gas inlet means for introducing said gaseous medium into said plenum chamber;
- a nozzle substantially coextensive with the plenum chamber in the plenum chamber longitudinal dimension;
- means dividing the nozzle into a plurality of parallel, straight channels oriented towards the goods being treated, each channel having an inlet end and an exhaust end;
- and
- means defining an elongated, constricted, substantially continuous slot substantially coextensive with the plenum chamber and nozzle communicating the plenum chamber with said channel inlet ends;
- the slot being sufficiently narrow to establish a pressure differential between the plenum chamber and the nozzle.
