1. A feedstock saccharification system comprising:
- a tank configured to contain a cellulosic or lignocellulosic biomass feedstock and a liquid medium;
a 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 dispersing system being configured to disperse the biomass feedstock in the liquid medium, the dispersing system comprising a chamber and, within the chamber, a rotating member which draws the feedstock and liquid medium into the chamber through the inlets, and expels a dispersion of the feedstock in the medium from the chamber radially through the outlet, to the tank; and

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.
