A device for the production and distribution of cold products, in particular for machines for the production of soft ice-cream, comprises a cylindrical chamber (12) equipped at one end with an inlet mouth (13) for a liquid food mixture and at an opposite end with an extraction tap (14) for the distribution of the cold food product, wherein said cylindrical chamber (12) is externally enveloped by an evaporation chamber (15) for the cooling of the liquid food mixture and contains in its interior a mixer (17). According to the invention, said extraction tap (14) is positioned on a closing flange (21) of said cylindrical chamber (12), wherein said flange (21) comprises an annular wall (22), which can be complementarily coupled with a front annular wall (31) of said evaporation chamber (15), and a housing (25) of the opening and closing organs of a nozzle (29), wherein said annular wall (22) and said housing (25) are made of a metallic material and put in thermal contact with each other for the cooling of the extraction tap (14).
