An atomizer for coating materials is provided. The atomizer includes two opposing discs connected by a central hub. Each disc includes an inwardly extending flange about its perimeter. The central hub has an exterior surface defining a v-shaped surface. When assembled in a coating apparatus, a fluid material, such as batter, may be dispensed toward the exterior surface of the hub while the disc is spinning. The resulting spray of fluid may be used to coat material effectively, while minimizing waste.
