Tangential shear homogenization and flash combined device with rotor / stator gap dimensions including uniform and non-uniform regions

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. A gap as a radially inner region having a radially outer region having a uniform dimension and at least one portion exhibiting a non-uniform dimension. The radially outer region defines a valve. In use, rotational movement of the rotor relative to the stator adds 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 (%).
