The demands on throughput and harvesting quality of combine harvesters are still growing,
so that improvements of the functional components are necessary. The tangential threshing
device, which is used in conventional and hybrid combine concepts, is known for its high
installation space and energy efficiency. Mostly there are just one or two parameters for
adjusting the concave clearance of tangential threshing devices which is not adequate for
describing the position of the concave and the analysis of the threshing process. With the
mathematical description of the curve characteristic over the separation length it is possible
to analyze especially multi-drum threshing devices, which is basis for further experimental
research.
