A beverage maker includes a body and a cover movably attached to the body. The body includes therein (among other components), a hot liquid generator (HLG) having a tank, an inlet for receiving liquid into the tank and an outlet, at least one heater in thermal communication with the liquid in the HLG tank, and a discharge port in fluid communication with the outlet of the HLG for discharge of the liquid. The cover is movably attached to the body between a closed position and an open position. At least one valve permits the discharge of the liquid via the discharge port in a closed position of the cover. The at least one valve is mechanically actuated by the cover in the open position of the cover to substantially prevent the discharge of the liquid via the discharge port.

Device and methods for brewing a beverage from a heated liquid chamber are disclosed in which the kinetic energy of rising air bubbles injected into a water heating chamber or delivery tube entrains the liquid in the water heating chamber to a delivery spout.

A technique allows display of a state in a process of extracting an extract from an ingredient. An extraction device includes a supply unit that supplies a liquid to an extraction vessel for extracting an extract from an ingredient, a control unit that controls the supply of the liquid by the supply unit, and a display unit that displays a state in the extraction vessel when the extract is extracted under the control of the control unit.

A beverage supply apparatus includes: a grinder configured to grind an ingredient; a hot-water supply unit configured to supply hot water; an extractor, to which the ingredient ground by the grinder, the hot water supplied by the hot-water supply unit, and pressurized air to stir the ingredient and the hot water are supplied; and a control unit configured to perform control to supply the pressurized air to the extractor to stir the ingredient and the hot water and, after the stirring, further supply pressurized air for extraction to the extractor to extract and supply beverage to a container. Further, the control unit controls the hot-water supply unit to add the hot water to the extractor during extraction of the beverage when a supply amount of the beverage to the container is equal to or larger than a volume of the extractor.

An air compressed coffee or tea making machine includes an air tank storing high pressure air; the air tank being connected to an air compressor for compressing external air so as to drive the high pressure air within the air tank; at least one liquid storage tank for storing liquid therein; a filtering tank installed below the air tank and connected to the liquid storage tank; a receiving tank installed below the filtering tank; the receiving tank serving for receiving coffee powders or tea powders therein. The liquid of the liquid storage tank is filled into the filtering tank; by the high pressure air from the air tank, liquid within the filtering tank suffers from a uniform air pressure and then flows to the receiving tank; as a result, the liquid is uniformly mixed with the coffee or tea powders within the receiving tank.

The present invention presents a pumping system (1) with a preheated reservoir (2), a main pump (4) for pumping a preheated liquid (3) from the reservoir (2), and pressurizing means (5) for pressurizing the reservoir (2). Preferably, the pressurizing means set an absolute pressure of 0.5 to 1 bar in the reservoir (2). The liquid (3) in the reservoir (2) can be heated up to 90 C. or more. The present invention achieves a nearly complete suppression of the phenomenon of cavitation at the main pump entrance, and thus achieves an increased pumping performance at elevated liquid temperatures.
