Through-Drying of Tissue Paper - Experiments and Modelling
In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). Therefore, the drying rates achieved in through-drying are often several times higher than in contact drying proc
