Abstract
A substantially air-tight vat completely encloses the rotatable cylinder. The pulp slurry fed into the vat is compacted to form a mat of high consistency. The differential pressure across the circumferential wall of the rotatable cylinder washes the mat with liquid contained in the wash chamber. The mat is removed from the cylindrical wall of the rotatable cylinder to provide a low consistency pulp slurry.
