Abstract: 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.

Abstract: A procedure for the production of granulated food, applicable especially to the production of granulated baby and infant food, such as infant food most analogously resembling mother's milk is disclosed. The process provides a new composition of matter consisting of a stable, well dosable, granulated food product, of defined formula, which after reconstitution does not cream up, and which, in the case of the closest approach to the composition of mother's milk, will inhibit intestinal putrefaction. In the process, selected pulverized components are fed into a fluidized bed granulator and remaining fluidized components are sprayed simultaneously, successively or in mixtures, at a product temperature of 30.degree. to 80.degree. C. whereby granulates are obtained. The granulates are dried in the fluidized bed and cooled with air.
