The apparatus comprises a unit for storing materials to be distributed, a storage unit, a dispensing nozzle (2) interchangeable with outlet by which the two associated food materials come out, a sheath (3) within which an interchangeable central tube (4) is provided with side openings as holes or slits for supplying secondary material towards the main material, and units for angular indexing of the central tube with respect to the sheath and/or to the dispensing nozzle. The central tube is provided, at its end, with a unit for angle indexing with respect to the sheath. The apparatus comprises a unit for storing materials to be distributed, a storage unit, a dispensing nozzle (2) interchangeable with outlet by which the two associated food materials come out, a sheath (3) within which an interchangeable central tube (4) is provided with side openings as holes or slits for supplying secondary material towards the main material, and units for angular indexing of the central tube with respect to the sheath and/or to the dispensing nozzle. The central tube is provided, at its end, with a unit for angle indexing with respect to the sheath and a unit for locking on the sheath close to the dispensing nozzle. The unit for indexing and locking is present in the form of spur or bosses obtained by molding during the preparation of the tube, which cooperates with additional conformations such as indexing and blocking notches provided at a base of the sheath. The dispensing nozzle comprises an outlet of a flattened section, a unit for angle indexing with respect to the sheath and/or the central tube for matching the angular position of the tube, and lateral openings of the holes or slits with the angular position of the dispensing nozzle. A thread is arranged in the nozzle for connecting with an additional thread carried by the sheath. The indexing angle of the nozzle with respect to the sheath is made at the end of screw by the thrust of the nozzle against a flange (9) of the sheath. |
