“…Controlling the process in which the material is organic is difficult because these materials change their properties over time. Such processes are usually nonstationary and nonlinear, for such processes advanced control algorithms must be used [38].…”

“…Response surface methodology (RSM) was used to plan experiment [37]. Cereal grain cleaning is a nonlinear process that requires advanced control algorithms [38], therefore a nonlinear controller was connected to the system [39]. The measurements were performed for five angles, with five repetitions for the entire range of the sieve drum rotational speed.…”

The article presents some of the research on the wider work related to testing and improving a new rotary cleaning device. The new cereal grain cleaning and separation device can support the development of sustainable agriculture in terms of seed purity and quality. This device is especially useful for small and medium-sized farms. This device has the characteristics of a multi-stage screen aided by an air stream (i.e., by pneumoseparation). The prototype was constructed at the University of Life Sciences in Lublin. The research was conducted at a test stand, which allowed changes in the operating parameters of the cleaner and their measurement. The scope of the tests included determining the influence of the inclination angle of the sieve unit (α) on the effectiveness and efficiency of oat grain cleaning. The experiment was carried out using two rotational spindle speeds: 5 and 75 rpm. The quality of the separation and cleaning of oat grains was evaluated using six cleaning process parameters: plump grain mass separation coefficient (Spg), fine grain separation coefficient (Sfg), fine impurities separation coefficient (Sfi), chaff separation coefficient (Sch), total coefficient of cleaning effectiveness (E), plump grain cleaning efficiency (qpg). Results showed the significant effect of the sieve drum inclination angle on the efficiency and effectiveness of oat grain cleaning.
