<p>An impregnation arrangement (1) includes a vertically arranged impregnator chamber (10), a first inlet (11) arranged at a bottom end of the chamber configured for introducing material to be impregnated into the chamber, a conveyor arrangement (20) configured for moving the introduced material in a direction from the bottom end of the chamber to a top end of the chamber, at least one outlet ( 12) arranged at the top end for extracting the impregnated material from the chamber, and a second inlet (13) configured for introducing impregnation liquid into the chamber. Further, the impregnator arrangement includes a second outlet ( 14) at the bottom end configured for extracting liquid from the chamber (10) during operation, to provide a liquid flow in the chamber (10) in a counter-current or opposite direction of the direction of the introduced material. Further, the arrangement (1) includes a third inlet (15) for introducing liquid into the chamber (10) at the top end and a cleaning arrangement (30) connected between the third inlet (15) and the second outlet (14) to clean the extracted liquid.</p> |
