Abstract

Et apparat for behandling av masse med en be- handlingsvæske omfatter en beholder (1) med en sylindrisk vegg (2), et innvendig silorgan (3) for uttrekk av væske fra massen, sammen med et antall fordeltngsrar (5) på utsiden av beholderen for til- førsel av behandlingsvæske til beholderen via et antall innløpsforbindelser (6). Ifølge oppfinnelsen er hvert fordelingsrør (5) dannet av et ringformet profil (20) og et motstående parti (21) av sylinder- veggen (2), idet profilet er innsveiset direkte på sylinderveggen, og profilet og sylinderveggpartiet mellom seg omslutter en fordelingskanal (22). Videre har hver innløpsforbindelse (6) en åpning (23) som strekker seg gjennom sylinderveggpartiet og forbinder fordelingskanalen med det indre av beholderen.
