Abstract

The drying of kraft paper at forced air conditions is provided and the influence of the drying air operational conditions on the process behavior is analyzed through the generalized drying curves proposal. The experimental apparatus consists of a metallic box where hot air was canalized over both surfaces of the paper sample. The influence of the samples thickness and the drying air temperatures and velocities in the drying curves and drying rate curves behavior is studied through the methodology of generalized drying curves and normalized drying rate curves, respectively. Finally, the possibility of fitting these curves is discussed.
