Papermaking PAPERMACHINE – DRYING Introduction
· "web" at the dry end of a paper machine is only half that at the wet end. Thus, the "falling rate" stage is due in part to diminished heat transfer. This occurs because water evaporation away from the hot surface creates a layer of dry paper in contact with the roll. Dry paper is a poor conductor of heat; indeed, it is a good insulator.
