Abstract

A rotary particle dryer has a shaft extending along an axis and a hollow drum coaxially and spacedly surrounding the shaft and rotatable about the axis in a direction. A set of axially extending inner baffles fixed to the shaft extend radially outward therefrom and each form at least one angularly open inner pocket. A set of axially extending outer baffles fixed to the drum extend radially inward therefrom and each form at least two angularly open outer pockets. Structure mechanically connects the inner baffles directly with the outer baffles.
