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.

An espresso coffee dispensing machine includes a preheating boiler with temperature control, at least one hydraulic pump, and at least one dispensing assembly with systems for heating and temperature control of the water. The machine includes at least one balance for weighing the ground coffee in a filter and the dispensed product. Manual or electronic components for controlling the thermal power delivered within the preheating boiler and by the dispensing assembly are also included in the dispensing machine. The machine performs, following a rise in the temperature of the water, a pre-infusion and a post-infusion at constant pressure and for a preset volume of water calculated via a volumetric meter. Between pre-infusion and post-infusion, a brewing or infusion at constant pressure occurs wherein a presettable water volume is dispensed following calculation of the weight of the ground coffee in the filter and the product dispensed according to a brew ratio.

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 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 method for generating a coffee beverage in an automatic coffee machine brewing device supplies pressurized brewing water at a brewing device brewing water inlet according to a first brewing water supply mode during a first time period. During a second time period, a brewing water parameter is determined correlating with the volume flow and/or pressure of the supplied brewing water. A mode adjustment variable is set for a second brewing water supply mode using the brewing water parameter. Brewing water is supplied at the brewing water inlet during the second time period according to the second brewing water supply mode. The mode adjustment variable defines at least one continuous mode for the second brewing water supply mode, in which the brewing water is continuously supplied, and a pulse mode for the second brewing water supply mode, in which the brewing water is supplied in pulses.

A brewer for brewing beverages in a brew basket, such as loose coffee or tea, is provided, where the flow of water to the brew basket alternates between water brewing phases and steam brewing phases during a single brew cycle, resulting in comparatively higher temperatures of water in the brew basket than conventional brewers. The frequency and duration of the water brewing phases and steam brewing phases during a brew cycle can be electronically controlled according to one or more predetermined programs. A reinforcing band is also provided for the lighted brew basket interior to strengthen the brewer head bowl in this area, and a single cup insert is also provided.

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 second reservoir is connected to the outlet end of the HWG. The second reservoir includes a discharge port, a gas vent and a skirt extending from a wall of the second reservoir further than the gas vent. The skirt at least partially surrounds the gas vent. At least a portion of the skirt is spaced laterally inwardly from an outer sidewall of the second reservoir.

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 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 disclosed. 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.
