Abstract

L'invention concerne un procédé et une installation de production, à partir de biomasse (1), dans une presse à granulés (2), de granulés (9), en particulier destinés à être utilisés comme matériau combustible dans des chaudières. La biomasse (1) est faite de fibres de cellulose et/ou de fibres, de copeaux ou de débris contenant de la lignocellulose et elle alimente, via un dispositif de dosage (4), la presse à granulés (2) qui est faite d'au moins une matrice annulaire (24) et d'au moins un rouleau broyeur (21). Le procédé inventif consiste en ce que, entre le dispositif de dosage (4) et la presse à granulés (2), la biomasse (1) est répartie à l'aide d'au moins un dispositif de distribution (12) de manière substantiellement régulière sur la largeur (10) de la zone d'entrée (11) entre au moins un rouleau broyeur (21) et la matrice annulaire (24) et/ou la biomasse (1) est répartie par le même dispositif de distribution (12) et/ou un autre dispositif de distribution (5, 13) régulièrement ou proportionnellement sur une section de distribution (20) comprenant au moins deux rouleaux broyeurs (21).
