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 (), at least one brewing group () for brewing coffee, and a thermosiphon circuit between said hot water generator and said brewing group including a hot water supply pipe () and a hot water return pipe (). According to the invention, one or more additional hot water supply pipes ('), separate from said main hot water supply pipe (), are provided between said hot water generator () or another hot water source and said brewing group (). 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.
