20.500.12556/RUL-187609 Analiza delovanja dveh sušilnic za sušenje koruznega zrnja Analysis of the operation of two dryers for drying corn husks Diplomsko delo obravnava analizo delovanja dveh sušilnic za sušenje koruznega zrnja, in sicer pretočne sušilnice (PS) in skladiščne sušilnice (SS). Namen raziskave je bil primerjati učinkovitost obeh sistemov glede na čas sušenja, porabo goriva, doseženo končno vlažnost koruznega zrnja in zmogljivost sušenja. Poskus smo izvedli leta 2025 na Kmetiji Malešič v Radovičih na hibridu koruze P9610 (Corteva Agriscience). Spremljali smo maso koruznega zrnja, začetno in končno vlažnost, temperaturo sušilnega zraka, relativno vlažnost zraka, čas sušenja in porabo goriva. Zbrane podatke smo obdelali v programu Microsoft Excel. Rezultati so pokazali, da je bila PS učinkovitejša od SS. Za sušenje 29,2 t koruznega zrnja je PS potrebovala približno 6,98 h, SS pa približno 71 h. Poraba goriva na tono posušene koruze je znašala 7,13 L/t pri PS in 10,12 L/t pri SS. Obe sušilnici sta dosegli enako končno vlažnost koruznega zrnja, ki je znašala 13,2 %. V času izvajanja poskusa je bilo s PS posušenih 972 t koruznega zrnja, s SS pa 116,8 t. Ugotovili smo, da konstrukcija sušilnice in način njenega delovanja pomembno vplivata na čas sušenja, porabo goriva in skupno učinkovitost procesa sušenja. Na podlagi rezultatov sklepamo, da je PS primernejša za sušenje večjih količin koruznega zrnja, saj omogoča hitrejše sušenje, večjo zmogljivost in manjšo porabo goriva na tono posušene koruze. This diploma thesis deals with the analysis of the operation of two dryers for drying corn husks, namely a continuous-flow dryer (PS) and a storage dryer (SS). The aim of the study was to compare the efficiency of both systems with regard to drying time, fuel consumption, final grain moisture content and drying capacity. The experiment was conducted in 2025 at the Malešič Farm in Radoviči using the maize hybrid P9610 (Corteva Agriscience). During the experiment, grain mass, initial and final moisture content, drying air temperature, relative air humidity, drying time and fuel consumption were monitored. The collected data were processed using Microsoft Excel. The results showed that the PS was more efficient than the SS. To dry 29.2 t of corn grain, the PS required approximately 6.98 h, while the SS required approximately 71 h. Fuel consumption per tonne of dried corn amounted to 7.13 L/t for the PS and 10.12 L/t for the SS. Both dryers achieved the same final grain moisture content of 13.2%. During the experiment, 972 t of corn grain were dried using the PS and 116.8 t using the SS. We found that the construction and operating principle of the dryer significantly affect drying time, fuel consumption and the overall efficiency of the drying process. Based on the obtained results, we conclude that the PS is more suitable for drying larger quantities of corn grain, as it enables faster drying, higher capacity and lower fuel consumption per tonne of dried corn. koruzno zrnje sušenje koruze pretočna sušilnica skladiščna sušilnica poraba goriva učinkovitost sušenja corn grain corn drying continuous-flow dryer storage dryer fuel consumption drying efficiency true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-12 07:15:19 2026-09-12 07:15:42 2026-09-15 10:46:29 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 288645 291119363 61496.pdf 61496.pdf 1 CCC7B716F13B47D54AD86774AE4F3979 4a155eabc769059efc211da3582bb9c9c716593aadfee82ec34472f66902fe60 0202bfba-ae69-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247300 Biotehniška fakulteta 0 0 0
