A fan unit provides an airstream acting on the crop as it falls from the upper end (14) to a lower end (16) of the separation chamber (12) and an agitation device (24) is provided adjacent the upper end (14). The agitation device (24) acts on 10 particles of the crop feed entering the separation chamber (12) to cause the distribution of particles horizontally across of the separation chamber (12) to be varied according to the physical characteristics of the particles.
