Abstract
Apparatus for convectively cooling bottles and the like in a heat transfer decorator. Bottles travel on an underlying conveyor where they are subjected to descending air streams issuing from a plenum chamber. Refrigerated or room temperature air is directed from the plenum chamber by a series of fans, and routed through a honeycomb flow straightener which reduces the helical turbulence of the air streams. The air streams pass between nozzle plates which further enhance the flow uniformity.
Claims8
Apparatus for convectively cooling articles travelling on a moving conveyor, comprising:
- a plenum chamber having a floor,
- means for supplying air to said plenum chamber to pressurize said chamber at above ambient pressure;
- a plurality of fans located in the floor of said plenum chamber for directing air streams toward the conveyor;
- a lattice of open cells located downstream of said fans and upstream of the conveyor, each of the cells having a passage with an axis in the direction of the conveyor so as to reduce turbulence of the air streams passing therethrough;
- and
- at least two plates located downstream of the lattice of open cells and straddling the articles travelling on the conveyor, said plates converging in the direction of said conveyor so as to direct said air streams uniformly over the articles.
