Vpliv sušilnih pogojev na konvekcijsko sušenje bukovine : diplomsko delo - univerzitetni študij = Impact of drying condition on convective drying of european beechwood : graduation thesis - university studiesMazi, JankoNa vzorcih bukovine (Fagus sylvatica L.) smo proučevali vpliv procesnih parametrov sušenja na hitrost masnega kapilarnega toka in na vzpostavljeni vlažnostni profil po prerezu lesa. Poskuse smo ... izvedli na radialno orientiranih preizkušancih debeline 6 mm, 12 mm, 18 mm in 24 mm. Konvekcijsko sušenje lesa smo simulirali v laboratorijskem sušilnem kanalu pri konstantni temperaturi (T = 30 °C) in konstantni relativni zračni vlažnosti (85 %), z variiranjem hitrosti zraka (h) od 0,6 m/s do 2,1 m/s. Med sušenjem smo v zaporednih časovnih intervalih gravimetrično določali povprečno lesno vlažnost (u), vlažnostni gradient in masni tok vode iz lesa vzorcev v okolico. Sušilna hitrost se je povečevala s hitrostjo gibanja zraka v sušilni komori ter zmanjševala z večanjem debeline preizkušancev. Povečanje začetne sušilne hitrosti je povzročilo krajšanje faze konstantne sušilne hitrosti. Prevelika začetna stopnja sušenja je povzročila takojšnjo nepovratno zaustavitev začetnega masnega toka vode in znatno podaljšala postopek sušenja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
