1. A method comprising:
- saccharifying a biomass feedstock in a vessel while mixing with a jet mixer, the biomass feedstock having been dispersed in a liquid medium using a dispersing system that draws the feedstock and liquid medium out of the vessel and recirculates the feedstock and liquid medium back into the vessel, the dispersing system having a solids inlet in communication with a solids source, a liquid inlet in communication with a liquid source, and an outlet, the dispensing system being configured to disperse the biomass feedstock in the liquid medium,wherein the dispersing system comprises a chamber and, within the chamber, a rotating member which draws the feedstock and liquid medium into the chamber axially, through the inlets, and expels a dispersion of the feedstock in the medium from the chamber radially through the outlet, to the tank.

Abstract
Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce ethanol. Biomass feedstock is dispersed in a liquid medium and then saccharified.
