ABSTRACT:
A tray assembly for use in receiving and retaining used moist brewing substances and the like from a beverage brewing apparatus and separating a liquid portion therefrom. The tray assembly is in communication with an entry port which deposits moist brewing substances therein. A drain line in the brewing apparatus carries separated liquids away from said tray assembly. The tray assembly includes a tray body, a liquid separation portion retained in said tray body for drawing off liquids from moist brewing substances, and a controllably sealable tray valve assembly attached to the tray body and operatively engaging the drain line for draining liquids from the tray assembly. A first area in the tray body between the entry port and the liquid separation portion communicates with the entry port and defines a receiving and retaining space. A second area in the tray body between the liquid separating portion and the valve assembly communicates with the tray valve assembly and defines a liquid collection space. Drained brewing substance is retained in the receiving and retaining space for removal at a later time. Liquid drawn off of the brewing substance into the liquid collection space flows from the tray assembly out through the tray valve assembly when engaged with the drain line.
