Abstract

La présente invention porte sur un appareil à combinaison d'évaporation et d'homogénéisation par contrainte tangentielle qui permet de déstructurer de la biomasse prétraitée et qui comprend un logement pouvant être relié à une source de biomasse prétraitée et mise sous pression, et un stator et un rotor montés à l'intérieur du logement. Le stator et le rotor sont disposés en confrontation et espacés par un intervalle axial. L'intervalle présente une région radialement extérieure ayant une dimension uniforme et une région radialement intérieure ayant au moins une section présentant une dimension non uniforme. La région radialement extérieure définit une vanne. En utilisation, un déplacement en rotation du rotor par rapport au stator communique une contrainte tangentielle à un volume de biomasse prétraitée. La contrainte tangentielle homogénéise le volume de biomasse prétraitée alors qu'une différence de pression provoque une séparation de phase partielle de la biomasse homogénéisée en phases vapeur et liquide de telle sorte que la biomasse prétraitée subit au moins une triple augmentation volumétrique totale et une transition de poids à une vapeur d'au moins un pourcent (1 %).
