Characterization of Medicinal Plants Sorting Process by Planar Sieving through Mechanical Oscillations Analysis

The mechanical sorting process of granular and vegetal materials is a complex technological process influenced by a series of factors from which we remind: mechanical vibratory motion, geometrical measures of the sorting equipment and technological factors. Based on correlations between the presented elements one can establish the technological parameters of the sorting process so that to realize a quality separation.In the paper we present a method for determination of mechanical oscillations influence on the quality of the sorting process with planar sieves. The experiments performed on a dimensional sorter with planar sieves aimed at identification of an optimum working set-up in terms of frequency and amplitude of the sorter’s vibrators, for a quality separation degree.
