Abstract
Particles to be dried are loaded into the bottom of an upwardly open vessel which is then spun about a central axis at a speed sufficient to form the particles into an annular body and to urge the particles radially outwardly with a centrifugal force greater than the force of gravity. The outer wall of the vessel is gas-pervious and drying gas is passed radially inwardly through this wall to contact the particles and at least partially fluidize the body of particles. The dried particles are drawn off out of the upper end of the rotating vessel as fresh wet particles are loaded into the lower end.
