摘要： A nozzle for spraying liquids is provided, especially high viscosity liquid media used in the food and chemical industries. The nozzle finds particular use in fluidized bed spray granulators. A fine spray of high viscosity liquid media is attained. A nozzle head is arranged inside a nozzle housing. The nozzle head has a cylindrical portion terminating in a truncated, cone-shaped portion. A plurality of first flow ducts are arranged like the threads on a screw along the surface of the cylindrical portion for guiding a pressure medium such as air. A plurality of second ducts are arranged between the cylindrical portion and truncated, cone-shaped portion of the nozzle head and supply high viscosity liquid medium to the pressure medium exiting the downstream ends of the plurality of first ducts. The mixing high viscosity liquid and pressure media are supplied to a nozzle outlet via the truncated, cone-shaped portion of the nozzle head, which is mated by the inner surface of a nozzle cap, both of which are hardened and polished to a mirror-finish.
