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.

The beverage preparation unit comprises a mixing chamber having a beverage outlet, a liquid flow path for supplying a liquid to the mixing chamber, and an air flow path for supplying air to the liquid flow path. The mixing chamber is arranged for receiving a beverage related ingredient, such as concentrate, preferably from an exchangeable supply pack. The liquid flow path is arranged for generating a hollow jet of liquid having an outer liquid portion extending in a flow direction of the jet and an inner air portion extending in a flow direction of the jet wherein the outer liquid portion surrounds the inner air portion.

A brewing apparatus including a group head and a portafilter shaped to engage the group head such that the group head forms a seal on the portafilter when the portafilter is in a locked position within the group head. The brewing apparatus further including a first vessel in fluid communication with the group head and a second vessel in fluid communication with the group head. The brewing apparatus also includes a vacuum pump configured to pump fluid from the first vessel through the group head and the portafilter and into the second vessel.

A system and method. The system may include a beverage machine including a pump, heater, a sensor, and a processor. The pump may be configured to pump fluid including gas or liquid. The heater may be configured to heat the fluid. The sensor may be implemented downstream of the pump and the heater. The sensor may be configured to sense a pressure, a flow rate, a steam quality, or a temperature of the heated fluid and to output sensor data including information of the pressure, the flow rate, the steam quality, or the temperature of the heated fluid. The processor may be communicatively coupled to the heater, the pump, and the sensor. The processor may be configured to: receive the sensor data; control operation of the pump or the heater; and based on the sensor data, adjust an operational parameter of the pump or the heater.

Methods and apparatuses for brewing beverages. A brewing system in accordance with an aspect of the present disclosure comprises a fluid conduit system, an air conduit system, a valve, and a pump. The valve is coupled to the fluid conduit system and the air conduit system. The pump is coupled to the valve. The valve selectively accesses the fluid conduit system and the air conduit system such that the pump selectively pumps fluid and selectively pumps air.

A water boiler for dispensing units of espresso coffee machines. It is composed of a first hollow body (2) having an upper end (12) and a lower end (3), in which conventional means are placed for attaching and detaching a portafilter (4), the latter being operable via a handle (5).

The boiler comprises a second hollow body (11) sealingly connected to the upper end (12) of the first body (2), and an electric heating serpentine resistor (13) accommodated in the cavities (9, 10) formed by the two hollow bodies (2, 11). A bottom wall (16) adjacent to the lower end (3) of the first body (2) has a plurality of ducts (22, 23, 24, 25, 29) which are part of the hydraulic circuit of the dispenser unit for supplying the beverage-forming hot water to the dose of pressed coffee contained in the filter.

The boiler includes a tubular element (19), having a predetermined volume capacity, inserted in at least one (25) of the plurality of ducts that are part of said hydraulic circuit for supplying hot water to the dose of coffee. This tubular element acts as a pre-infusion chamber for the dose of coffee and is removably mounted in said bottom wall (16) of said first body (2), to be able to be replaced with another one having a different capacity.

A method and an apparatus are disclosed for brewing hot beverages, such as African green tea or Ataaya, including using a software-controlled electromechanical teapot to control and direct the beverage through various stages of mixing, boiling, cooling, and dispensing with multiple pumps, while monitoring the appropriate temperatures and time to take various actions or transition to various stages of brewing. In various embodiments, the electrical-electronic teapot includes various indicators such as buzzers, information display, lights, and the like to inform the user of various events and states, such as when the beverage is ready for serving. Additionally, a processor or microcontroller may be utilized in the teapot to run the software that controls the operation of the teapot. In some embodiment, the software is configurable, updatable, and/or changeable to alter the operation of the teapot for improved performance or to change the brewing method for different beverages.

A hot beverage maker manifold assembly is disclosed integrating components into the manifold body minimizing leak paths and creating efficient overall drain and vent performance of the aircraft hot beverage maker. A top vent valve is integrated into the manifold body for complete venting and draining performance in the manifold assembly as well as in an associated hot water tank and tank lines. An incorporated flow regulator housing within the manifold body at a tea line exit fitting limits the number of downstream leak paths and complexity. An integrated lower manifold clean out port allows for efficient bi-directional service of the manifold and efficient descaling and flushing.

A liquid extract production system capable of efficiently producing a liquid extract. The system comprising an extractor for extracting a liquid extract from extraction raw materials, a liquid extract tank for storing the liquid extract, a flow path of liquid extract that connects the extractor and the liquid extract tank, a flow meter for measuring the flow rate of the liquid extract provided in the flow path, a density meter for measuring the solid content concentration of the liquid extract provided in the flow path, a solid content calculation unit for calculating the solid content included in the liquid extract that flowed through the flow path based on the measured flow rate and solid content concentration, and a liquid transfer controller for controlling the transfer of liquid extract from the extractor to the liquid extract tank based on the calculated solid content.
