<p>Prikazana je procedura modelovanja prekidnog sušenja materijala sfernog oblika u tankom sloju, nakon čega je pokrenuta računarska simulacija procesa na osnovu predloženog modela. Zatim, odrađeno je eksperimantalno istraživanje, za šta su korišćeni svježe ubrani orasi u ljusci, bez komine. Nakon što je statistički potvrđena pouzdanost modela, on je iskorišćen kao baza formiranje modela za simulaciju sušenja u debelom sloju. Posle toga su urađeni eksperimenti i za druge materijale različitih osobina (krompir, bundeva i kestenje), da bi se izveli zaključci o mogućnosti energetske uštede u procesima konvektivnog sušenja u zavisnosti od fizičkih osobina materijala. Ovim istraživanjem pokazano je da su sa stanovišta uštede energije prekidni režimi konvektivnog sušenja preporučljiviji kod materijala koji imaju veću efektivnu difuzivnost.</p> / <p>This research shows the procedure of modeling the intermittent drying of sphereshaped<br />materials in a thin-layer, after which the computer simulation was done, based<br />on the proposed model. Тhe experimental investigation has been done, where the<br />fresh collected in-shell walnuts had served as the main drying material. As the model<br />reliability was experimentally confirmed, it was used as а basis for creating а model for<br />deep-bed drying simulation. Afterwards, the experimental investigation was done for<br />other materials as well (potato, pumpkin and chestnuts), in order to draw the<br />conclusions concerning the possibility of energy saving in convective drying processes,<br />as it depends on physical properties of a material. This research showed that, from the<br />perspective of energy saving, it is more advisable to use an intermittent regime if a<br />material has a higher effective diffusivity.</p>
