Description

ABSTRACT:
A pair of rotatable shafts are mounted within a housing. The shafts are spaced apart along the same plane with each shaft having a plurality of longitudinally spaced disks mounted thereon. The space between the shafts and the dimensions of the disks are such that disks on each shaft extend into the space between adjacent disks on the other shaft to provide pressing areas. One shaft is rotated clockwise; the other shaft is rotated counterclockwise.
A slurry or semi-solid is fed into the in-running sides of the disks. A cake forms on the disks by the flow of liquid through liquid passageways in the disks. Pressing to a high consistency takes place in the pressing areas. The cake thus formed is removed from the disks at the out-running sides of the disks.
