Patent

CA 2248172

A method and an apparatus for drying a load of moist fibrous material, particularly a load of laundry washed and placed in a washer/drier machine or a clothes drier, wherein a closed-circuit flow of superheated steam at 102-180 ·C and substantially at atmospheric pressure is passed through the load of fibrous material. The method is characterized in that, prior to the superheated steam drying step, the air in the closed circuit is flushed therefrom by means of steam.

La présente invention concerne un procédé et une installation de séchage d'une masse de matière fibreuse humide, notamment d'une masse de linge lavée et placée dans une machine lavante-séchante ou un sèche-linge, dans lequel on fait passer à travers la masse de matière fibreuse, en circuit fermé, de la vapeur d'eau surchauffée à une température comprise entre 102~ et 180 ~C et sensiblement à la pression atmosphérique. Ce procédé est caractérisé en ce qu'il comprend, avant la phase de séchage avec de la vapeur d'eau surchauffée, une phase préalable de chasse de l'air, présent dans le circuit fermé, au moyen de vapeur d'eau.
