abstract:
Results of conditioning treatments of some fodder materials on the moisture content of resulting material before pelleting and after it are presented in the study. A strong linear relationship was observed, both between temperature of treatments and steam pressure, and the resulting moisture of powdered material (R = 0.994). Average moisture ranged from 15.19 to 22.03%. It was observed, for a majority of the materials under study, that steam conditioning results in lower moisture level of material obtained after pelleting in comparison when the procedures using addition of water were employed only. For the two compared treatments, the average moisture of pellets ranged from 13.51 to 18.43% for steam conditioning, and from 10.23 to 21.22% for water addition.
