Abstract

A vortex dryer for fibrous material utilizes a helical inlet to the base of a central vortex tube to separate fiber from debris by abruptly changing direction of the conveying air flow. The dryer combines the helical input with helical shaping of the air flow through the central vortex tube to induce greater drying for the fiber which is continued at the top of the vortex tube through a separate drying chamber.
