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.

Process and apparatus for removal of liquid from a solid particulate

In a process for the production of sugar thick juice from lime-containing raw juice and wherein carbon dioxide and soda are added to the lime-containing raw juice in at least one carbonation step, and wherein the thin juice is preheated and evaporated to form thick juice, ammonia in the form of gaseous spent heating medium originating from the preheating of the thin juice is added to the lime-containing raw juice. The method of the invention results in a reduction of the consumption of soda in the carbonation step and in an increased sugar yield.
