The invention relates to a filter element and its manufacture to be used in removal of liquid from solids containing material to be dried in a capillary suction dryer which filter element contains a ceramic microporous layer having the pore size under 5 micrometer and supported by a ceramic internal layer having recess areas for liquid flowing. The rotor includes a center chopping section and a pair of fans respectively positioned at longitudinally outboard ends of the center chopping section. This can shorten the processing time needed for the generation of the vector font character image.
