Abstract

An infusion chamber has a top perimeter cover that defines an aperture to pass air to an air vent and receive fluid from fluid outlets. The infusion chamber has an outer chamber and an inner chamber positioned within the outer chamber, where the spacing between the outer chamber and the inner chamber defines a void. An air manifold is positioned at the base of the inner chamber. The air manifold includes air inlet channels, air exit channels and an interior solids filter. The infusion chamber also has a base housing positioned at the bottom of the infusion chamber, and a plunger positioned in the base housing to selectively evict liquid from the inner chamber.
