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.

A full immersion brewing system includes an immersion chamber; an extraction material mechanism for introducing extraction material into the immersion chamber; an infusion mechanism for introducing heated liquid and pressurized air into the immersion chamber; and a drain/dispensing mechanism for dispensing, through a filter, infused liquid from the immersion chamber and for enabling removal of extraction material from the immersion chamber. The filter prevents extraction material from being dispensed from the immersion chamber. When the drain/dispensing mechanism is in a first position, infused liquid is dispensed through the filter, and when the drain/dispensing mechanism is in a second position, the filter is positioned so that extraction material and liquid is dispensed without going through the filter. The full immersion brewing system includes a cleaning mechanism for cleaning the immersion chamber and the filter.

A portable, battery-operated vacuum infusion machine includes a top container assembly with a compartment that houses an air pump, a battery, and a controller. The top container assembly couples to the top opening of a separate bottom container. When coupled together, the top and bottom containers are connected by flow holes superimposed by a filter in the top container. An air pump switched on or off by a controller exerts negative pressure in the bottom container by means of a suction port and induces liquid in the top container to enter the bottom container under pressure while the filter in the top container ensures that the infusion residue is separated from the liquid and only the prepared infusion has passage to the bottom container. The bottom container can be opened by means of removing the top container in order to allow for serving the prepared infusion.

A beverage preparation machine for preparing at least one beverage from a beverage material includes a modem for communication with a remote resource such as a server, and is configured to send machine remote management data to the remote resource. The machine comprises location system configured for automatic geolocation of the machine, and is configured to send to the remote resource location information determined by the location system. This for example makes it possible to confirm or correct the location of a machine, to correct mistakes that can occur when a machine is installed or moved, or to take appropriate measures when a machine is stolen. In another embodiment, a system includes such a beverage preparation machine and a remote resource with which it is configured to communicate. In a further embodiment, a method is provided for remote management of a beverage preparation machine.

A brewer system includes a reservoir, a steeping chamber movable relative to the reservoir and positioned over a mouth of the reservoir, and a filter tape positioned between the chamber and the reservoir. Brewing substance and water are added to the chamber and can be controllably agitated using a controllable gas pump coupled to the reservoir to form a brewed beverage. The brewed beverage can be drawn through the filter tape and into the reservoir through the mouth under the influence of a controllable vacuum pump coupled to and controllably communicating with the reservoir.

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.
