Title (EN) METHOD IN DRYING OF PAPER
(FR) PROCEDE DE SECHAGE DU PAPIER
Abstract: front page image
(EN)A method in consolidation and drying of paper. A wet web (2) is contacted with superheated steam, whose temperature is 200-600 °C, for the purpose of reducing, by heat transfer from the superheated steam, the water content of the web (2) by evaporation of a substantial part of the water in the same. The wet web (2) is supported and transported by means of a heat-conductive, gas-impermeable belt (4) 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 (2) facing away from the belt (4).
(FR)Cette invention concerne un procédé de consolidation et de séchage du papier. Ce procédé consiste à mettre une bande de papier mouillé (2) en contact avec de la vapeur surchauffée à une température de 200-600 °C, afin de réduire sensiblement la teneur en eau de la bande par évaporation. La bande de papier mouillé (2) est maintenue et acheminée au moyen d'une bande transporteuse thermoconductrice imperméable aux gaz (4) dont la largeur est égale ou supérieure à celle de la bande de papier, cependant que des jets de vapeur surchauffée sont projetés sur le côté de la bande (2) opposé à la bande transporteuse (4).
