ABSTRACT:
A disposal device for disposing of spent beverage brewing substances for use with a beverage brewing apparatus. The beverage brewing apparatus is the type which produces a brewed beverage from a beverage brewing substance disposed in a brewing chamber and infused with a liquid. A drain conduit extends from the brewing chamber and communicates with the substance disposal device for removing a slurry of moist beverage brewing substance and liquid waste from the brewing chamber of the apparatus into the disposal device. The disposal device includes a housing and a filter assembly which are controllably displaceable relative to each other. When the housing and filter assembly are assembled, they define a chamber. The filter assembly has a filter material which drains a liquid component out of the slurry when the slurry is dispensed into the chamber. A drain port communicates with the chamber for removing the liquid component from the chamber. An evacuating device communicates with the chamber and creates a vacuum on the chamber when activated to assist in removing the liquid component from the slurry. Once a substantial portion of the liquid component is removed from the slurry under the influence of the evacuating device, the housing and filter assembly are disengaged to remove the drained component of the slurry from the chamber.
