Abstract: A device for cooling one or more delivery ducts (1a, 1b, 1c, 1d, 1e) for liquids in a beverage dispensing apparatus of a type comprising at least one tubular body (2), the delivery ducts and at least one conveying duct (3) for a forced flow of a cooled fluid being housed therein. Said tubular body (2) of the device comprises at least one inflow section (7) for the cooled fluid, which is fluidically communicated with this conveying duct, and at least one outflow section (6a, 6b, 8) for the cooled fluid, which is placed at a higher height than the inflow section.

Abstract: A post-mix beverage dispensing device of a type comprising at least two sources for the liquids to be mixed, which are fluidically communicated with at least two respective ducts, at least one delivery tap for a beverage, which is fluidically connected to said ducts, as well as for at least one of these ducts, means for adjusting the flow rate and/or pressure of the liquid, which are placed upstream of the delivery tap. The device also comprises, for each of these ducts, a bypass channel being provided with a relative plug, these bypass channels being provided with a respective outlet opening, which is placed downstream of the relative plug, and being interposed between the delivery tap and said means for adjusting the flow rate and/or pressure.
