摘要： The present invention relates to a system (70) comprising at least one coffee machine (10) and at least one accessory device (30) associated with said coffee machine, as well as to a method for controlling operation of such system, which allow to adjust the characteristics of the panel of coffee powder that are required for preparing a coffee-based beverage in order to obtain a high quality beverage. The invention provides for storing in a memory, for each coffee-based beverage that can be prepared by the coffee machine, a reference profile of the water flow rate flowing through the panel of coffee powder as a function of time, detecting the actual profile of said flow rate, and comparing the actual profile of the flow rate with the reference profile in order to ascertain deviations that are higher than a predetermined threshold. If deviations that are higher said threshold are ascertained, the invention provides for identifying and implementing suitable corrective actions before the subsequent brewing of a same beverage.

摘要： 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. Furthermore, if several brewing groups are provided, the water temperature during the brewing step can be advantageously controlled and adjusted in an autonomous and independent manner for each brewing group.
