Abstract
The main objective of this work is to model heat transfer in Kraft paper during drying. The model developed takes into account BIOT's assumptions regarding a uniform temperature environment; the paper used is assumed to be thermally thin (BIOT number Bi < 0.1). The results obtained are experimentally validated. They allowed us to show that the two drying phases of Kraft paper can be modeled by a thermal capacitor that charges upon contact with the drying cylinder (phase 1) and discharges into the free space (phase 2).
