Tangential shear homogenization and flash combined device with parameters depending on non-uniform rotor / stator gap dimensions and variable rotor / stator gap dimensions

摘要

A tangential shear homogenization and flash compounding device that destroys the structure of the pretreated biomass comprises a housing connectable to a source of pressurized pretreated biomass, and a stator and rotor mounted within the housing. Prepare. A stator and a rotor arranged facing each other and spaced apart by an axial gap of non-uniform dimensions. The minimum axial dimension between the rotor and stator that defines the restriction for the biomass flow. In use, rotational movement of the rotor relative to the stator imparts tangential shear to a volume of pretreated biomass. Tangential shear homogenizes the volume of pretreated biomass, while a pressure differential results in partial phase separation of the homogenized biomass into the gas phase and liquid phase, thereby pretreating the pretreated biomass. , The total volume increases at least 3 times and the weight transitions until the gas is at least 1 percent (%).
