The invention relates to a method for producing a solids cake created in filtering performed by a suction drier provided with a fine porous liquid suction surface, in which method there is created, in order to produce said solids cake, a pressure difference in between the filter surface of the fine porous filter medium and the surface opposite to said filter surface. According to the invention, in connection with the filter cake formation, the pressure difference between the filter surface of the fine porous filter medium and the surface opposite to said filter surface is controlled in order to adjust the cake formation speed, and the slurry surface of the suction drier filtering tank is advantageously maintained on a level that enables the use of at least one filter surface cleaning member, essentially throughout the whole filter cake formation process.
