Abstract
A vacuum dryer that has upper and lower platens brought together against the load handled by the application of a vacuum. A manifold, with means for producing a pressure within the manifold different from atmospheric, is used to seal one platen against the other. A flexible means joins the manifold to a platen whereby they are relatively displaceable.
