1. A particulate separating mechanism for an appliance, the particulate separating mechanism comprising:
a fluid inlet that receives an inlet fluid, wherein the inlet fluid includes particulate matter;
a labyrinth separator positioned to generate a first turbulence of the inlet fluid, wherein the first turbulence separates a first portion of the particulate matter into a particulate collector disposed within a base of the labyrinth separator;
a main filter positioned downstream of the labyrinth separator and having a constricting portion and opposing turbulence chambers that are vertically oriented to produce a second turbulence of the inlet fluid, wherein the second turbulence separates a second portion of the particulate matter from the inlet fluid; and
a fluid outlet that delivers the inlet fluid having the first and second portions of the particulate matter removed into a processing chamber for processing articles, wherein
the labyrinth separator includes a plurality of labyrinth chambers that are positioned in a horizontal configuration;
a drain channel is positioned below the plurality of labyrinth chambers for collecting the first portion of the particulate matter from the particulate collector; and
the plurality of labyrinth chambers includes at least one operable particulate membrane that delivers the first portion of the particulate matter from the particulate collector to the drain channel.
