  • Low wet pressure drop limiting orifice drying medium and process of making paper therewith
    Patent number: 6021583
    Abstract: An apparatus for drying a cellulosic fibrous structure. The apparatus comprises a micropore medium having pores therethrough. The pores are the limiting orifice in the air flow used in the drying process. The micropore medium has a relatively low wet pressure drop therethrough. This relatively low wet pressure drop advantageously reduces the energy costs used in drying, and/or allows for greater drying to be obtained at constant energy costs.
