Abstract

Et apparat for dehydrering av materialsuspensjoner under deres passering mellom to pressvalser (10), hvor væske presses inn ved overtrykk gjennom skalloverflate- ne til valsene, og den endelige dehydreringen foregår ved pressing i en klemme (11) mellom valsene (10). Det øvre partiet av valsene (10) er omgitt av en forihg (12) med et innløp (14) for suspensjonen. Et utløp for materialbanen er plassert under klemmen (11), og doktorblad (16) er plassert i forbindelse med begge val- sene (10) under klemmen (11), Overføringen av det dehydrerte materialet foregår ved hjelp av tyngdekraft.
