  • Patent number: 10087578
    Abstract: Provided is a discharge device for discharging pretreated biomass from a pressurized reactor. The device comprises: a vessel having an opening to a high pressure region at the top, and configured to be connected with a pressurized biomass pretreatment device; one or more inlet openings situated along the sides of the vessels through which water or liquid may be added; an orifice or valve at a lower part of said vessel, said orifice or valve being configured to eject pretreated biomass, optionally into a pipeline. The discharge device is characterised in that it comprises mechanical agitation means, said agitation means comprising an agitation element arranged in the interior of said vessel at a lower part of said vessel, and being configured to provide agitation of the content of said vessel, wherein said agitation means being adapted to withstand a pressure in the interior of a said vessel of 10 bar or more.
