ABSTRACT:
An improved flighting for dryers is the subject of the present invention. An elongated drying drum is disposed for rotation about its longitudinal axis. The inner surface of the drum is provided with a plurality of material distributing vanes in circumferentially spaced relationship. The vanes are characterized by first surface extending generally transverse to a tangent to set body at the point of attachment and a second wedge-shaped surface intersecting the first surface. The wedge-shaped surface may also be provided with a lip extending circumferentially therefrom. A plurality of interference structures are disposed from a central longitudinal support and provide means for distributing material gravitating from the outer peripheral vanes. A plurality of return flighting members are disposed along the inner surface of the drum between the afore described material distributing vanes. These flighting members are disposed at an angle and conform generally to the curvature of the inner surface. A method of drying a product includes passing the product through a dryer, rotating the dryer, and comminuting the product while it is being dried.
