Unit for manufacturing titrated mixtures, for mixing at least one first liquid component with at least one second liquid component, comprising: a plurality of mixing vessels each provided with a respective drawing-off outlet (40s-43s); for each first component: - a storage vessel dedicated to said first component; - an intermediate weighing vessel dedicated to said first component, mounted on an intermediate weighing device, suitable for determining variations in weight of a content of said intermediate weighing vessel; - double-direction pumping means, arranged to transfer some of the first component between the storage vessel and the intermediate weighing vessel both dedicated to the first component; and - a set of first pipes capable of transferring content from the intermediate weighing vessel dedicated to the first component selectively to each mixing vessel; for each second component: - a heat-regulated storage vessel (20, 30) dedicated to said second component; and - a set of second pipes (21, 31) capable of transferring quantities of said second component from the storage vessel (20, 30) dedicated to said second component selectively to each mixing vessel; characterised in that it is suitable for the mixing vessels to be dedicated respectively to different concentrations of the or one of the first components in the mixtures, and in that the mixing vessels are disposed at respective distances with respect to the intermediate weighing vessel of said first component, so that said distances increase according to said concentrations of the first component in the mixtures. a plurality of mixing vessels each provided with a respective drawing-off outlet (40s-43s); for each first component: - a storage vessel dedicated to said first component; - an intermediate weighing vessel dedicated to said first component, mounted on an intermediate weighing device, suitable for determining variations in weight of a content of said intermediate weighing vessel; - double-direction pumping means, arranged to transfer some of the first component between the storage vessel and the intermediate weighing vessel both dedicated to the first component; and - a set of first pipes capable of transferring content from the intermediate weighing vessel dedicated to the first component selectively to each mixing vessel; - a storage vessel dedicated to said first component; - an intermediate weighing vessel dedicated to said first component, mounted on an intermediate weighing device, suitable for determining variations in weight of a content of said intermediate weighing vessel; - double-direction pumping means, arranged to transfer some of the first component between the storage vessel and the intermediate weighing vessel both dedicated to the first component; and - a set of first pipes capable of transferring content from the intermediate weighing vessel dedicated to the first component selectively to each mixing vessel; for each second component: - a heat-regulated storage vessel (20, 30) dedicated to said second component; and - a set of second pipes (21, 31) capable of transferring quantities of said second component from the storage vessel (20, 30) dedicated to said second component selectively to each mixing vessel; - a heat-regulated storage vessel (20, 30) dedicated to said second component; and - a set of second pipes (21, 31) capable of transferring quantities of said second component from the storage vessel (20, 30) dedicated to said second component selectively to each mixing vessel; characterised in that it is suitable for the mixing vessels to be dedicated respectively to different concentrations of the or one of the first components in the mixtures, and in that the mixing vessels are disposed at respective distances with respect to the intermediate weighing vessel of said first component, so that said distances increase according to said concentrations of the first component in the mixtures.
