Abstract
A method and an apparatus for dividing a liquid into droplets is disclosed. One or several disks (35) rotate about an axis (A) and are provided, at their outer peripheral edges, with circumferentially equidistant, uniform cusps. A distributing device (20) is adapted to distribute the liquid uniformly and circumferentially on the disks (35), whereby the liquid discharged onto the disks (35) is formed into a uniform thickness film which spreads radially outwardly towards the cusps (36) and is divided thereby into uniform size droplets. The distributing device (20) may comprise a dosing container (21) which is rotationally independent of the disks (30) and from which the liquid is dosed through one or several dosing openings (26) onto the disk or disks (35), the disks (35) preferably being rotated relative to the dosing openings (26).
