  • Patent number: 5289643
    Abstract: An apparatus for drying a moist particulate material having a non-uniform particle side with superheated steam includes a cylindrical part wherein a number of parallel, substantially vertical elongated chambers is located in ring form, one or more of the chambers having a closed bottom and the remaining chambers having a steam-permeable bottom, the adjacent chambers being interconnected, and an upper conical part which is also divided into chambers and which at a lower end is connected with the chambers of the cylindrical part of the apparatus, the chambers of the conical part of the apparatus being divided into smaller chambers by inclined guide plates, wherein at least part of each of the inclined guide plates in the conical part of the apparatus is hollow and can be heated by supplying superheated steam hereto.

  • Patent number: 4813155
    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.
