Abstract
The present invention relates to the use of a mechanical apparatus to convey a workpiece through a fluidized bed dryer. In particular, the invention relates to a single or multiple stage vibrating fluidized drag conveyor having spaced apart conveyor paddles attached to a continuous chain or a similar device, and driven by a variable frequency motor drive. The invention is of particular applicability in the case of low-density workpieces where chaotic motion of air may disrupt or reverse the orderly flow of workpieces through the dryer.
