Abstract
Method and apparatus for treating particles of food or other substances with a gas, e.g., hot air, to effect blanching, dehydration, puffing, or the like. Feature of the invention is a system wherein the particles are contained in a perforated cylinder which is rotated at a speed sufficient to produce a centrifugal acceleration of at least one g, while a unidirectional flow of gas is applied to the cylinder perpendicular to its axis of rotation.
