Contributions to the Optimization of the Medicinal Plant Sorting Process into Size Classes

This study aims to optimize and assess the quality of sorting process into homogeneous size classes dried chopped medicinal plants, by obtaining multivariate regression functions polytropic polynomial forms. Assessment was carried out calculating average coefficient separation. The influence several important factors (material feed rate on sieve, sieve dimensions, inclination angle, oscillation frequencies) followed. Research nettle herb (Urtica dioica) using a plant sorter with plane sieves, which allowed for modifying some constructive functional parameters, making it possible obtain optimal values. results showed that dry in bulk at 4 mm, moisture 11.45%, optimally sorted (index separation coefficient, 0.922) if following parameters were met: drive mechanism speed n = 1000 rpm; angle α 12.08°; material-specific flow q kg/dm·h; recommended length L 1.4 m. It observed high rates, decreased decrease speed, when decreased, increased. maximum deviation 5.5% function. new advanced processing technologies plants involve short-term production quality-finished products, thus supporting processors consumers phytotherapeutic products beneficial effects health.
