dc.description.abstractPrikazana 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.sr
dc.description.abstractThis research shows the procedure of modeling the intermittent drying of sphereshaped materials in a thin-layer, after which the computer simulation was done, based on the proposed model. Тhe experimental investigation has been done, where the fresh collected in-shell walnuts had served as the main drying material. As the model reliability was experimentally confirmed, it was used as а basis for creating а model for deep-bed drying simulation. Afterwards, the experimental investigation was done for other materials as well (potato, pumpkin and chestnuts), in order to draw the conclusions concerning the possibility of energy saving in convective drying processes, as it depends on physical properties of a material. This research showed that, from the perspective of energy saving, it is more advisable to use an intermittent regime if a material has a higher effective diffusivity.en
