Abstract

The present invention discloses an extractor suitable for extracting chemical through cleaning of waste (30) comprising a plurality of longitudinally aligned drums (3) for rotary movement about a horizontal axis, each drum (3) having a pair of spaced end walls (7), wherein the juxtaposed end walls of adjacent drums (3) provide openings (3) for waste 30 communication between the adjacent drums (3), and each drum (3) includes a transfer means (9) including a shaped wall for scooping the waste (30) so that the waste (30) is transferred from one drum (3) to an adjacent successive drum (3) through said openings (3) during rotation of the drums (3), characterised in that wherein the shaped wall of the transfer means (9) comprises an interrupted contact surface (5) to reduce contact time between the waste (30) and the transfer means (9) during waste transfer from drum (3) to drum (3).
