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.

Method, machine and boiler for the preparation of beverages, in particular infusions such as coffee or tea; wherein the boiler has a central tank which delimits a superheating area for a liquid and an outer tank positioned around the central tank so as to delimit a heating area for the liquid and to allow the heating of the liquid in the heating area by means of the heat generated in the superheating area; the heating area having a first outlet for supplying hot liquid, the superheating area having a second outlet for the supply of steam.

The present invention provides a boiler structure, for use with a coffee machine and capable of automatic depressurization, comprising a lid, a sealing member, a boiler body, and a position-limiting support frame. The lid is configured with a water inlet pipe and a water outlet pipe and the water outlet pipe. The sealing member is fitted in an inner side of the lid and having a pressure relief ring, wherein the pressure relief ring has one or a plurality of pressure relief apertures at a pressure relief height. The boiler body is on one side of the lid, wherein the boiler body comprises a receiving space and an opening. The receiving space is in communication with the water inlet pipe and the water outlet pipe, and the opening is on one side of the receiving space. A heating device is on one side of the boiler body. The boiler body is movable downward by pressure while being heated by the heating device; and, when the opening of the boiler body reaches the pressure relief height, the pressure is relieved. The position-limiting support frame is on the side of the lid such that the boiler body lies between the position-limiting support frame and the lid and is limited in displacement.

A cyclic preheating coffee pot includes a main body, a brewing cavity, a water supply apparatus, a heating apparatus, a water inlet pipe and a water outlet pipe mounted on the main body, and a control apparatus, a driving apparatus and a flow dividing structure mounted on the main body. The water supply apparatus is communicated with the heating apparatus, the water supply apparatus is configured to supply water to the heating apparatus, and the water outlet pipe is communicated with the heating apparatus and the flow dividing structure. The flow dividing structure includes a first branch. The water outlet pipe is communicated with the water supply apparatus via the first branch, such that the water supply apparatus, the water inlet pipe, the heating apparatus, the water outlet pipe and the first branch are communicated and form a cyclic pipeline provided with a one-way valve apparatus or a water pump.

A coffee maker and method of operating the same is disclosed. The method includes deactivating a heating plate of the coffee maker when a drip pan is positioned thereon, soliciting a user-selection of a serving size from a plurality of serving sizes when the drip pan is positioned on the base, and operating a pump of the coffee maker to advance fluid to a filter basket in accordance with the selected serving size.

The invention concerns a unit for controlling transmission of power to a thermal conditioning device e.g. for coffee machine, comprising a controller with a start-up profile for starting-up the device from a temperature of inactivity to an operative temperature for bringing to a target temperature a fluid circulating through said device at start-up end, the controller being arranged to allow circulation of fluid through the device at start-up end and to compare the determined temperature of fluid circulated at start-up end to the target temperature and derive a temperature difference therefrom. The start-up profile has at least one parameter and in that the controller has a self-learning mode for adjusting the parameter as a function of the temperature difference and to store the adjusted parameter for a subsequent starting-up of the device. The invention concerns in particular a method for optimized heating up of a coffee machine.

A drinks preparation machine for preparing brewed drinks from a portion package with an extraction material includes a water tank, a pump, a water heater and a brewing chamber for receiving the portion package. The pump delivers water from the water tank into the brewing chamber via the water heater. A temperature sensor measures a temperature along the fluid path including an initial temperature at the location of the temperature sensor at least in one operating condition after a switching-on procedure or waking-up procedure and before a possible heating-up procedure of the water heater, and, after the water heater has reached an operating temperature, to carry out a rinsing procedure of the brewing chamber with water from the water heater, when and only when the measured initial temperature corresponds to a certain condition, and only subsequently to effect an introduction of the portion package into the brewing chamber.

A two-stage water boiler for a hot beverage vending machine, comprising a storage water heater and a continuous-flow water heater fluidically connectable in series; wherein the storage water heater is configured to contain water at atmospheric pressure, and the continuous-flow water heater is configured to be supplied, through a water pump, with water drawn from the storage water heater.

The invention concerns a unit (1000) for controlling transmission of power to a thermal conditioning device (100) e.g. for coffee machine, comprising a controller (2) with a start-up profile for starting-up said device (100) from a temperature of inactivity (TI) to an operative temperature for bringing to a target temperature (TT) a fluid circulating through said device (100) at start-up end, said controller (2) being arranged to allow circulation of fluid through said device (100) at start-up end and to compare the determined temperature (SOT) of fluid circulated at start-up end to the target temperature (TT) and derive a temperature difference therefrom. It is characterized in that the start-up profile has at least one parameter and in that said controller (2) has a self-learning mode for adjusting said parameter as a function of said temperature difference and to store the adjusted parameter for a subsequent starting-up of said device (100).
