1. An apparatus for pretreating a biomass, the apparatus comprising:
a reaction vessel for pressurizing and rapidly depressurizing a biomass within the reaction vessel,
wherein the reaction vessel comprises an inner perforated screen forming a cage for holding the biomass and separating the biomass from a wall of the reaction vessel, and
wherein the inner perforated screen forming a cage further comprises one or more perforated screen fingers positioned within the biomass during pressurization of the biomass to increase exposure of the biomass to steam.
