A heating apparatus and method of heating. The embodiments of the invention relate to coffee machine heating apparatuses for providing heated brew water for passing through coffee grounds. The apparatus and method involves using low pressure steam (i.e. less than 1 bar absolute) at a saturation temperature that is substantially equal to the desired brew water temperature. Advantageously, improved temperature control of the brew water is achieved in a manner which is more convenient to an end user. The operating temperatures are more stable (the need for a “cooling flush” is removed) and the operating temperatures is reached in a quicker manner than with conventional machines.

A machine and method for preparing a hot beverage includes a device for producing and conveying hot water; a holding device into which a filter holder can be releasably inserted; a feed for the hot water, the feed having an outlet arranged above the filter holder in order to dispense hot water onto the filter holder from above into a receiving area which is open towards the top and comprises an extraction material; and a drive device in order to move the feed for the hot water relative to the filter holder. The filter holder has a chamber for water, the chamber being fillable via an opening, and the feed can be moved relative to the filter holder between a position substantially vertically above the opening and another position substantially vertically above the receiving area comprising the extraction material.

The coffee maker of the present invention includes a housing, a water reservoir disposed in the housing and a shower head in fluid communication with the water reservoir. The coffee maker also include a first heating element for heating water from the water reservoir and being controllable between and ON state and an OFF state, and a second heating element located downstream from the first heating element and being controllable between an ON state and an OFF state. The first and second heating elements are operable in at least a first mode and a second mode, the second mode being different from the first mode.

A machine for preparing beverages includes at least one tank for water fluidly connected to a filtering container suitable to contain an aromatic mixture and to an outlet for the beverage associated with selective delivery devices; a pump to feed the water from said tank; a heating device to heat the water in transit, and a control and command unit connected to a user interface.

A beverage brewing system includes a case, a reservoir, a pump, a heating element, and a holder. The case defines a cup reception bay for receiving a cup and a nozzle assembly positioned above the cup reception bay. The reservoir is positioned within the case for containing a fluid. The pump is positioned within the case for pumping the fluid from the reservoir to the nozzle assembly. The heating element is positioned within the case for heating the fluid as the fluid is pumped to the nozzle assembly. The holder holds a pour over bag that has an opening configured to receive a beverage precursor. The nozzle assembly pours the fluid into the pour over bag through the opening, and the fluid flows through the beverage precursor and through the pour over bag into a cup positioned within the cup reception bay.

Coffee machine (1) for preparation of a hot beverage with a heating system for dynamic thermal management, comprising a housing frame (2), in which are accommodated a water module (100) for providing brewing water, which comprises a first heating device (120), having a boiler (121) with a fresh water inlet (12) and with a first heating element (123) for providing water heated to a first temperature T.sub.1 and a brewing module (200), whereby the brewing module (200) comprises a brewing device (220) for brewing a predefined amount of coffee with brewing water and a dispensing unit (230) for dispensing brewed coffee, as well as, disposed in a brewing water feed line (260), a second heating device (250), to heat the water heated to the first temperature T.sub.1 to a second temperature T.sub.2. The coffee machine provides for the second heating device (250) accommodated in the brewing module (200) being a thick film heater (252) designed as continuous flow heater.

In order to reduce limescale formation on the continuous flow heater during operation of an apparatus for preparing freshly brewed hot beverages which has a hot water generator, which is embodied as a continuous flow heater, and a brewing apparatus, to which hot water from the hot water generator can be supplied, a controller for actuating the continuous flow heater is provided, which controller switches on the continuous flow heater for the purpose of drawing a pre-specified quantity of hot water and switches off said continuous flow heater shortly before the quantity of hot water is completely output, so that the temperature of the hot water at the output of the continuous flow heater is declining at the end of the drawing operation.

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 extraction apparatus includes: a first burr grinding supplied whole beans, a first burr through-hole defined in the first burr, a first burr inlet receiving the whole beans, a first burr outlet discharging coffee powder, a second burr inserted into the first burr through-hole through the first burr outlet to define a grinding space for grinding of the whole beans with the first burr, a burr coupler coupled to the second burr to move the second burr, a first rotary part coupled to the first burr to rotate the first burr, a second rotary part connected to the burr coupler and rotating to move the burr coupler in an axial direction of the first burr to adjust a depth of insertion of the second burr into the first burr, an extractor that receives and mixes the coffee powder and water to extract coffee liquid.

Device and methods for brewing a beverage from a heated liquid chamber are disclosed in which the kinetic energy of rising air bubbles injected into a water heating chamber or delivery tube entrains the liquid in the water heating chamber to a delivery spout.
