Abstract

The invention relates to a feeding arrangement (1) for feeding comminuted biomass material through a treatment stage (200), which feeding arrangement comprises a screw feeder (10), which comprises an inlet (12) and an outlet (13), and a feed screw (2) for transporting the biomass material from the inlet to the outlet. The feed screw comprises at least one screw flight (2b) with a pushing flight surface (PF) and a leeside flight surface (LF). The feeding arrangement comprises a supply channel (SC) arranged to supply anti-fouling liquid from at least one liquid supply source (So, So), and a plurality of nozzles (NZ) connected to said supply channel, which are arranged to distribute said anti- fouling liquid over the leeside flight surface for establishing a liquid layer on said leeside flight surface. The invention also includes the use of said screw feeder in hydrolysis processes and method for operation of said screw feeder.
