Drying Kinetics of Poplar (Populus Deltoides) Wood Particles by a Convective Thin Layer Dryer

Drying of poplar wood (Populus Deltoides) particles was carried out at different drying conditions using a laboratory convective thin layer dryer. Drying curves were plotted and in order to analyze the drying behavior, the curves were fi tted to different semi-theoretical drying kinetics models. The...
