Abstract: In a coffee extracting apparatus in which coffee essence is extracted from coffee powder (200) in a container (51), an air feeding arrangement (43) is provided for feeding pressed air into the container. After the coffee essence is extracted from coffee powder, coffee grounds (200') are remained in the container. It is assumed that the coffee grounds are adhered to an inner surface of the container. In order to expel the coffee grounds from the container, the air feeding arrangement is controlled so that the pressed air is fed into the container after extracting the coffee essence from the coffee powder.

Abstract: In a coffee extracting apparatus in which an extracting container (51) extracts coffee essence from coffee powder with being supplied with hot water of substantially normal pressure and elevated temperature, a water control valve (48) controls a feed of the hot water to the extracting container. The hot water is fed to the extracting container with being pressed in a water feeding device (43). The coffee essence is taken out from the extracting container together with the hot water through a filter member (53, 54) supported by a support member (52).

Abstract: A coffee brewing apparatus has a first cylinder for containing hot water having a top opening, a vertically extending shaft fixedly connected to the first cylinder, the shaft having a hot water release channel vertically therethrough and a pressure-operated hot water release valve disposed in the channel, a vertically movable piston, a vertically movable second cylinder for holding ground coffee therein having top and bottom openings and disposed below the first cylinder coaxially therewith, and a vertically movable plunger sealingly and slidingly connected with the shaft. The plunger has an internal cylindrical chamber and a shallow hot water spreading chamber in a bottom section thereof. When the plunger is lowered, the bottom section thereof enters the second cylinder and compacts the ground coffee therein.
