With the steadily increasing installed engine output of the combine as well as the increasing
market share of hybrid and axial threshing systems, further optimization of the functional
assemblies in the combine cleaning unit is necessary. All the more a high rate of MOG
(material other than grain) discharged from the residual grain separation is related to the
hybrid and axial threshing system, which makes the cleaning more difficult. A crucial influence
on a high cleaning performance is exerted by the pre-separation of the crop flow consisting
in grain and MOG in the preparation pan (pp). To achieve this aim - a high cleaning performance
– an investigation was realized in collaboration with the company CLAAS Selbstfahrende
Erntemaschinen GmbH. A serial preparation pan was replaced by a partially ventilated step to
create a fluidised bed.
