RAW-MATERIAL SUPPLY DEVICE AND BIOMASS SEPARATION DEVICE

摘要

A raw-material supply device for supplying a biomass raw material (11) under pressure, wherein the device is provided with: a screw body (31), provided inside a screw feeder (35) and adapted for compressing, rotating, and transporting the powdered biomass raw material (11) using a motor (M) from a normal-pressure input section for the input biomass raw material (11) to a high-pressure discharge section; and a pressing plug (32) provided on the tip section (31d) side of the screw body (31), the pressing plug (32) having a plug tip (39) for retaining a high-temperature/high-pressure field (36) against the discharge force of compressed consolidated biomass (33). The interior of the screw feeder (35) comprises a raw-material supply region (51) for supplying the biomass raw material (11) in the raw-material transport direction, a raw-material compression region (52) for compressing the biomass raw material, a raw-material consolidation region (53) for consolidating the biomass raw material in the form of a cork, and a material seal section (54) for maintaining the high-pressure field using the consolidated biomass (33).
