Abstract: A coffee machine is provided that comprises one or more brewing groups and that has a system for delivering water under reduced pressure at a step of pre-infusion of the coffee panel before the step of actual infusion and brewing of the coffee-based beverage. Each brewing group (3a, 3b) of the coffee machine (1), a secondary feeding duct (9a, 9b) in which water under higher pressure flows, and a secondary bypass duct (11a, 11b), in which water under reduced pressure flows, can selectively be communicated with the respective brewing group. The pre-infusion system of the coffee machine (1) allows effecting pre-infusion in each brewing group in a separate and independent manner.

Abstract: The invention relates to an arrangement comprising a coffee machine (100) and a coffee grinder (200), wherein said coffee machine is able to prepare a plurality of different coffee-based drinks according to several recipes. In order to avoid errors when preparing a specific recipe, the coffee machine (100) comprises a plurality of brewing groups and a corresponding plurality of filter holder assemblies (1), and at least one filter holder assembly (1)—preferably each filter holder assembly (1)—comprises an electronics (11) equipped with a memory (15), in which the parameters of one or more of said recipes are stored, and with communication devices (13) that allow said filter holder group to communicate on one hand with the electronics (101) of the coffee machine (100) and, on the other hand, to communicate with the electronics (201) of the coffee grinder (200), whereby said filter holder assembly communicates to each device the data necessary for preparing the selected recipe.

Abstract: The present invention relates to a coffee machine, more particularly to an espresso coffee machine. The coffee machine according to the invention comprises at least one hot water generator (1, 3), at least one brewing group (5) for brewing coffee, and a thermosiphon circuit between said hot water generator and said brewing group including a hot water supply pipe (13) and a hot water return pipe (15). According to the invention, one or more additional hot water supply pipes (13?), separate from said main hot water supply pipe (13), are provided between said hot water generator (1, 3) or another hot water source and said brewing group (5). Thanks to this arrangement, it is possible to guarantee a greater steadiness in the water temperature during the steps of brewing coffee, and possibly the capability of quickly adjusting, even in real time, said temperature.

Abstract: The present invention relates to a component configured to be associated with a pipe arranged to supply a pressurized fluid into a beverage in order to admix the fluid to the beverage. The component includes a venturi having a first, upstream region at high pressure and low kinetic energy, and a second, downstream region at low pressure and high kinetic energy for said fluid. In the component, a first plurality of throughholes forms the venturi and puts the first region into communication with the second region, and a second plurality of throughholes is arranged so as to converge towards the second region. The present invention also relates to a device including the component and to a method of admixing a fluid to a beverage.
