ABSTRACT:
Objects constituted by a porous web-like material, such as a paper web, a granular material, such as peat, or a solid material such as wood, are dried by placing the same in contiguity with a fine porous liquid suction surface which itself is in liquid communication with a liquid volume with the latter being in communication with apparatus by which the liquid in the liquid volume is maintained at an underpressure relative to the pressure of the liquid in the object to be dried so that liquid flows from the object into the fine porous suction surface. The liquid flow can be enhanced through the application of an over pressure or through the direction of radiation onto the object to be dried. In one embodiment, the fine porous liquid suction surface comprises the surface of a rotatably mounted cylinder whereby a web-like object, such as a paper web, can be dried as the same is carried on the cylinder surface.
