Abstract
In known rack dryers, the drying effect is weaker in the outer area on the side of the air intake into the pipe chambers than in the other areas. Said weaker drying effect is caused by turbulence in this area, which leads to a drop in the static pressure. The aim of the invention is to provide a dryer which ensures even drying of the goods across the entire width, even in the problem areas. The rack dryer is equipped with conductive bodies (20, 26) which are located on the partition wall (5) and which streamline the current in the area of the air intake into the pipe chambers in such a way, that a predominantly even static pressure prevails throughout the entire pipe chamber. The invention can be used for drying sandwich-type plaster board or wood veneer.
Claims10
A dryer for flat workpieces, the dryer comprising:
- a housing;
- an upright partition in the housing defining a treatment space and a vertical feed chamber to one side of the space, the housing having a collecting chamber to an opposite side of the space and a passage extending horizontally between the collecting chamber and feed chamber;
- conveyor means in the treatment space for displacing the workpieces longitudinally and horizontally through the housing in a plurality of vertically spaced levels;
- respective nozzle boxes extending at the levels above and below the workpieces, having ends open at the partition into the feed chamber, having opposite closed ends, and formed with holes open vertically toward the workpieces;
- means including a blower for drawing air out of the collecting space, passing it through the passage to the feed space, and forcing it through the boxes and out of the holes;
- and
- respective flow-guide bodies projecting from the partition into the feed chamber between the open nozzle-box ends.
