Abstract
Liquid is evaporated from a particulate solid material by passing the material through a row of upwardly open, elongated interconnected cells and introducing superheated steam into the cells at their lower ends in a manner so as to impart to the particles a whirling movement. Dried particles are lifted out of the cells and into a common transfer zone and from said zone down into a discharge cell which has no steam supplied thereto. The dried material thus introduced into the discharge cell is discharged together with material which has passed the row of cells. The invention eliminates the need for effecting an initial disintegration of the solid particulate material.
