Dans la presse de pelletisation (3), au moins un dispositif de pelletisation (12) composé d'un rouleau (5) roulant sur une matrice (4) comprime la biomasse (1) à travers les perçages (13) de la matrice (4) pour former des pellets (10), la matrice (4) et/ou le rouleau (5) pouvant être déplacés l'un par rapport à l'autre dans un mouvement relatif lors de la fabrication. L'invention vise à permettre une bonne accessibilité et un échange rapide d'éléments ou de modules machine essentiels, et à mettre en oeuvre une construction et un fonctionnement modulaires de la presse de pelletisation de telle manière que la production puisse être réglée de façon variable et/ou que la production soit indépendante de la réparation de modules individuels. A cet effet, la presse de pelletisation (3) comporte au moins un dispositif de pelletisation (12) composé d'au moins un rouleau (5) et/ou d'une matrice (4) à l'intérieur d'une structure de presse (21), la structure de presse (21) se présentant sous la forme d'au moins une cadre en forme de C (18) et/ou d'au moins un dormant (20).
