ABSTRACT:
An apparatus for beverage brewing using heated liquid to infuse a beverage brewing substance during a brewing cycle. The apparatus includes a brew chamber which is positioned for communication with a reservoir having a filter positioned between the brew chamber and the reservoir. A quantity of beverage brewing substance is placed in the brew chamber and a quantity of heated water is placed in the reservoir. A pumping device pumps the water in the reservoir to the brew chamber to infuse the beverage brewing substance and produce a brewed beverage. The brewed beverage created in the brew chamber drains through the filter between the brew chamber and the reservoir and is captured by the reservoir. The brewed beverage and any remaining heated water are recirculated through the beverage brewing substance in the brew chamber for a period of time. At a desired period in the brewing cycle, a valve connected to the reservoir is operated to open the reservoir and drain the brewed beverage therefrom. The pump device drains the recirculation path between the reservoir and the brew chamber and forces air through the spent beverage brewing substance thereby expelling moisture from the spent beverage brewing substance. A plunger is used to enclose the beverage brewing substance in the brew chamber and deposit water from the pump to infuse the brewing substance. At the end of the cycle, the brew chamber is displaced from the filter and reservoir and the plunger expels the spent beverage brewing substance.
