Abstract:
1. A machine ( 10 ) for the preparation and distribution of cold food products, used in particular but not exclusively for the production of soft ice-cream, comprising a cylindrical chamber ( 12 ) equipped at one end with an inlet mouth ( 14 ) for a liquid food mixture and at an opposite end with an extraction tap ( 18 ) for the distribution of the cold food product through at least one distribution nozzle ( 36 ), wherein said cylindrical chamber ( 12 ) is externally enveloped by an evaporation chamber ( 20 ) for the cooling of said liquid food mixture and contains in its interior, a mixer ( 24 ), and wherein underneath said distribution nozzle ( 36 ) there is a protection door ( 62 ) for said distribution nozzle ( 36 ), characterized in that said machine ( 10 ) comprises at least one continually switched on ultraviolet-ray lamp ( 48 ) positioned on the main body of said machine ( 10 ) in correspondence with said distribution nozzle ( 36 ) and inserted inside a metallic casing ( 50 ) integral with said main body, said ultraviolet-ray lamp ( 48 ) being positioned to sterilize said distribution nozzle ( 36 ) of the machine ( 10 ) wherein said ultraviolet-ray lamp ( 48 ) is inserted inside a hollow cylindrical body ( 54 ), which is in turn contained inside said casing ( 50 ), said hollow cylindrical body ( 54 ) being equipped with at least one slit ( 56 ), said hollow cylindrical body being positioned axially over said ultraviolet-ray lamp ( 48 ) in order to direct ultraviolet rays, emitted from said at least one slit ( 56 ) of said hollow cylindrical body ( 54 ), exclusively in the direction of said distribution nozzle ( 36 ), wherein said hollow cylindrical body ( 54 ) is rotatable around its own axis so that the ultraviolet rays emitted from said lamp ( 48 ) do not emerge from said metallic casing ( 50 ) when it is not necessary to effect the sterilization of said distribution nozzle ( 36 ); wherein said metallic casing ( 50 ) comprises a part facing said distribution nozzle ( 36 ), wherein said part extends along said distribution nozzle ( 36 ) and comprises at least one transparent wall ( 52 ) which allows the passage of ultraviolet rays towards said distribution nozzle ( 36 ) and protects said ultraviolet-ray lamp ( 48 ) from possible damage from spurts of product ( 16 ) or foreign bodies.
