First Claim
1. A method of conveying a material under an electron beam, the method comprising:
- exposing a biomass material to an electron beam while conveying the biomass material on a vibratory conveyor, wherein the vibratory conveyor comprises a vibratory conveyor trough having a first surface conveying the biomass, andcooling a second surface of the vibratory conveyor trough,wherein the first and second surfaces of the vibratory conveyor trough are in thermal communication.

Abstract
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, while cooling equipment and the biomass to prevent overheating and possible distortion and/or degradation. The biomass is conveyed by a conveyor, which conveys the biomass under an electron beam from an electron beam accelerator. The conveyor can be cooled with cooling fluid. The conveyor can also vibrate to facilitate exposure to the electron beam. The conveyor can be configured as a trough that can be optionally cooled.
