Procédé d'obtention de matières de ballast, à partir des drèches de brasserie, pour obtenir un produit destiné à la consommation humaine, plus riche en fibres et en matières de ballast et plus pauvre en graisse et en lipides, ce procédé comprenant (a) un traitement des drèches à l'eau chaude, (b) un brassage du mélange, (c) un traitement mécanique avec élimination d'albumine, (d) un pressage, (e) un séchage et (f) un broyage final du produit à une granulométrie prédéterminée. On propose également une variante de ce procédé où un acide faible chaud remplace l'eau chaude. An energy-efficient method of recovering roughage from brewery residues (draff), including adding water to the draff and mixing to form a mixture of a soft protein fraction and a hard roughage fraction, separating the soft protein fraction from the hard roughage fraction, and removing water from the separated roughage fraction. After separating water the roughage fraction may be dried, and comminuted. In contrast to other methods, the separation into roughage and protein fractions is performed before the drying step and only the roughage fraction of interest is dried.
