Abstract

See full text

A raw-material supply device for supplying a biomass raw material under pressure, wherein the device is provided with: a screw body, provided inside a screw feeder and adapted for compressing, rotating, and transporting the powdered biomass raw material using a motor from a normal-pressure feed section for the fed biomass raw material to a high-pressure discharge section; and a pressing plug provided on the tip section side of the screw body, the pressing plug having a plug tip for maintaining a high-temperature/high-pressure field against the discharge force of compressed consolidated biomass. The interior of the screw feeder comprises a raw-material feed region for feeding the biomass raw material in the raw-material transport direction, a raw-material compression region for compressing the biomass raw material, a raw-material consolidation region for consolidating the biomass raw material in the form of a cork, and a material seal section for maintaining the high-pressure field using the consolidated biomass.
