A washer or hydro-extractor comprising a cylindrical basket adapted to be rotated about its longitudinal axis for liquid extracting operations on wet material placed therein. A plurality of rigid flaps within the basket are selectably pivotable about respective axes extending longitudinally of the basket. The flaps normally lie substantially flat against the inner cylindrical surface of the basket. A respective cam follower is rigidly coupled to each flap via a respective crank arm. In order to selectably pivot the flaps for stripping caked material from the inner surface of the basket, a stripper cam is selectably displaceable into a position in which it engages the cam followers of those flaps which, at any instant during stripping, lie in what is, at that time, the upper part of the basket, whereby the latter flaps are pivoted from their normal positions for effecting stripping. |
