Abstract: An improved cyclone dryer is disclosed, having an outer cylinder, an inner cylinder, and a cone-shaped chamber. The outer cylinder has a tangential airstream orifice for injecting a high-speed stream of material and air, or other gases, into the dryer. The inner cylinder has a plurality of apertures and a plurality of deflectors that deflect air and material into a cavity defined by the inner cylinder and the cone-shaped chamber. The cone-shaped chamber, the outer cylinder, and the inner cylinder define an annular air chamber. An exhaust assembly is attached proximate the inner and outer cylinders, and is in fluid communication with the cavity.

Abstract: An improved cyclone dryer is disclosed, having an upper, a lower cylinder and a cone-shaped chamber that define a cavity. The improved dryer is adapted for a high-speed airstream to enter the cavity via a tangential airstream orifice. Wet material is fed into the improved dryer via an input assembly that is mounted proximate an exhaust assembly and feeds wet material into the cavity, at a point proximate a lower portion of the cylinder and proximate the cone-shaped chamber.
