  • Method in drying of paper
    Patent number: 6742280
    Abstract: A method in consolidation and drying of paper. A wet web is contacted with superheated steam, whose temperature is 200-600° C. for the purpose of reducing, by heat transfer from the superheated stream, the water content of the web by evaporation of a substantial part of the water in the same. The wet web is supported and transported by means of a heat-conductive, gas-impermeable belt whose width is equal to or exceeds the width of the web, and jets of the superheated steam are directed towards the side of the web facing away from the belt.
