Abstract
The invention relates to a method for making the drying of materials, particularly finely divided materials, more effective, in which method, of a slurry containing liquid and solids there is made a filter cake (2,12,22) onto the surface of the filter medium (1,11,21). According to the invention, the filter cake (2,12,22) and the oscillator (6,15,25) are arranged, in relation to each other, so that in between the filter cake (2,12,22) and the oscillator (6,15,25), there is generated an acoustic field by virtue of a mechanical contact between the filter cake (2,12,22) and the oscillator (6,15,25) or a structural element (7,16,26) connected to the oscillator.
