<p>An air-tight vat (10) under pressure completely encloses a rotatable drum (12). The vat (10) is constructed so that it may be completely submerged in liquid. The vat has a liquid filled take-off chamber (32). The pulp is fed to the vat through a pulp inlet (14). The pulp is formed and compacted to form a pulp mat. Directly following the forming and compacting of the pulp is a washing zone for washing the pulp mat. After washing the pulp mat is again compacted. The pulp mat is removed from the drum at a removal point located in the liquid filled take-off chamber, thus providing a pulp suspension in the take-off chamber. The suspension is removed from the vat through a pulp outlet (61) extending from the liquid filled take-off chamber (32).</p> |
