The present disclosure provides a beverage dispenser and a beverage brewing method. The beverage dispenser is formed with a liquid chamber, a brewing chamber, a heating chamber that can heat up liquid, and a pressure chamber that can pressurize the liquid. The liquid chamber, the heating chamber, the pressure chamber, and the brewing chamber form a circulating liquid circuit, in which the liquid formed in the liquid chamber enters into the heating chamber. The liquid is heated in the heating chamber and then enters into the pressure chamber. The liquid is pressurized in the pressure chamber and then enters into the brewing chamber, and then flows out of the brewing chamber and enters into the liquid chamber. The beverage dispenser and the beverage brewing method provided in the present disclosure overcomes the drawbacks of manually adding hot water and manually pressurizing for producing beverage.

A portable coffee brewing system includes a container, a lid assembly, a pump positioned within a hollow interior of lid assemble, a basket configured to hold an amount of coffee grounds and a tube fluidically connecting the pump to the basket. The lid assembly is connected adjacent the upper end of the container. The tube has an upper end of the tube fluidically connected to the pump and a lower end fluidically connected to the basket. When activated, the pump moves fluid via the tube to cause liquid in the hollow interior of the container to be moved through the amount of coffee grounds in the hollow interior of the basket thereby brewing coffee.

A portable coffee brewing system includes a top housing containing a pump and a tube. Portable coffee brewing system also includes a basket housing having a punch operatively connected to the top housing and having a receiving member; the basket housing having a receiving member configured to receive a basket. The basket being capable of holding a coffee grounds holding device which is capable of holding coffee grounds. A nozzle is attached to the lower part of the basket to create an opening for fluid to flow through. The system providing a user with a means of brewing coffee by inserting a coffee grounds holding device into a basket. A punch within the basket punctures the coffee grounds holding device; the basket then being operably connected to the rest of the system so fluid can move through the system when the system is activated to brew coffee or other beverages.

A kitchen appliance includes a first reservoir for receiving a liquid to be used for preparing a beverage. A hot water generator (HWG) has an inlet end, an outlet end and a passageway extending therebetween. The inlet end of the HWG is connected to the first reservoir. Liquid from the first reservoir flows into the HWG through the inlet end. A selector valve is connected to the outlet end of the HWG. At least a portion of the selector valve is movable by a user between a first valve position and a second valve position.

A professional coffee machine includes a supporting frame; a boiler mounted thereon with a tank of at least 8 liters receiving water and heating it to a temperature of about 122-130 C. for the thermo-controlled production of pressurized steam; a preheater having a first heat exchanger associated to the boiler so that the boiler water heats, by heat exchange, the supply water crossing the first exchanger to a first temperature T.sub.1 that is lowerly close or substantially equal to a second temperature T.sub.2, optimal for preparing a coffee infusion; a dispensing unit of the coffee infusion having its own thermo-controlled heating element, configured to bring the water outlet from the preheater to the second temperature T.sub.2, if T.sub.1 is less than T.sub.2; a thermal insulating member that mechanically constrains the dispensing unit to the supporting frame; and a dispenser of pressurized steam in communication with the tank.

A professional coffee machine includes a supporting frame; a boiler; a preheater to prepare a coffee infusion having a first heat exchanger with the boiler to heat the supply water crossing the first exchanger to a first temperature T.sub.1 close or substantially equal to a second temperature T.sub.2 corresponding to the optimal temperature for a coffee infusion; a dispensing unit of the coffee infusion having a thermo-controlled heating element that brings the water released from the preheater to the second temperature T.sub.2 if T.sub.1 is lower than T.sub.2; a thermal insulator that mechanically constrains the dispensing unit to the frame; a heater for preparing a tea infusion or the like having a second heat exchanger with the boiler to heat the supply water crossing the second heat exchanger up to a third temperature T.sub.3 corresponding to the optimal temperature for preparing a tea infusion or the like.

A portable coffee brewing device includes a lid pivotally connected to an upper end of the container by a hinge and button. A heating element housing and an electrical component housing is connected to a lower end of the container. A drain is positioned in a bottom wall of the container and is fluidly connected to a heating element positioned within the heating element housing. The heating element is controlled by electrical components positioned in the electrical components housing. A drip tube is fluidly connected to the heating element and the lid. A single serve coffee holding device is positioned below the lid. When the container is filled with fluid and the heating element is powered, heated fluid is forced up the drip tube through the passageway in the lid and into the coffee grounds holding device in a continuous cycle. The device is connectable to an external power source.

A method of operating a tankless beverage brewing apparatus that includes a digital controller for dynamically varying the water temperature and/or the brew flow rate of the dispensed beverage is shown. In some embodiments, a main supply line of the tankless beverage brewing apparatus includes a pressure reducer, a pressure sensor, a linear heater, a temperature sensor, and a spray valve; all supplying a hot water spray head and/or a hot water spigot. The inlet of the main supply line of the tankless beverage brewing apparatus may be connected directly to the local cold water supply. The controller uses feedback from the temperature sensor and/or the pressure sensor to dynamically vary the water temperature and/or the brew flow rate depending on the type of beverage being brewed.
