According to the invention, biomass from an agricultural crop in a naturally damped state is crushed in screw presses for further processing. After pressing to separate a low-solid phase, the remaining high-solid phase is processed with pressurized vapor. Expansion occurs, a vapor phase is separated and the high-solid phase is cooled, wherein substances are decomposed under the influence of enzymes and/or fermentation with microorganisms, while a gaseous phase is separated. A low-solid and a high-solid phase is separated in the remaining mixture. All separated phases are used to obtain preferably ethanol, protein concentrate and fibers or are reprocessed. A screw press (200) enabling continuous implementation of said method comprises axially disposed inline chamber areas (201...204) with a common integral shaft (205) and screws (206...211) arranged thereon. Said chambers are tightly sealed off from each other by compacted material plugs. The aqueous liquid phase is reprocessed (215...217) in the opposite direction to said material. An additional chamber area (218) having its own screw can connect two partial areas (203...204) to each other, thereby forming a loop with the advancing material. |
