Abstract

Starting from the influencing parameters of threshing and separation and implicit seed losses that occur within this process, this paper searched for and identified the optimal threshing regimes to minimize losses depending on the process parameters. The evacuation losses ( p ev ) depend on threshing rotor speed ( n ) and implicit rotor peripheral speed ( v p ), material feed speed ( v a ), the space between the rotor and counter-rotor ( δ ), material feed flow ( Q ), material density ( ρ ), and the length of the threshing apparatus ( L ). As the parameters ρ and L are constant, the variation of losses in relation to each of the arguments was followed: v p , Q , ρ , and v a , respectively, for the minimization of losses by the variation of the loss function by two arguments each (represented graphically); the four arguments targeted being: v p , v a , ρ, and Q . Using these input parameters, it was possible to determine the optimal threshing regimes for the variation of losses in relation to the rotor peripheral speed, the feed flow, the space between the rotor and the counter-rotor, and the feed speed, so as to obtain a seed separation percentage ( S s ) as close as possible to 100% (and implicitly the smallest threshing losses—towards zero) in relation to these parameters.
