Abstract: An infusion bag is disclosed wherein granular coffee is contained in a water-permeable portion which is attached to a water-reservoir portion whereby water passes downwardly in a positive manner from the reservoir into the receptacle to contact the granules and then the coffee brew is passed outwardly from the receptacle. Strings attached to the receptacle permit positive opening and closing of the receptacle with positive water action through the bag. The infusion bag is particularly suited to brewing coffee from ground coffee beans.

Abstract: A heat exchanger comprises an outer chamber having an inlet and outlet for passing a flow of air through the outer chamber. An inner chamber is disposed within the outer chamber and has a second inlet and a second outlet for passing a flow of gas through the inner chamber. Heat exchange tubes are arranged in the inner chamber whereby the flow of gas contacts the outer surface of the tubes. A baffle device is disposed between the inner and outer chamber for directing the flow of air from the inlet, through a first section having heat exchange tubes, into the outer chamber and back into a second section having heat exchange tubes, so that air passes through the heat exchange tubes in the first and second sections.
