Abstract

A dispensing apparatus is provided for application of a viscous sauce to a pizza shell. The apparatus includes a distribution roller system in combination with a waterfall dispensing device to form a thin sheet of the sauce that is discharged onto the roller which then throws the received sauce in droplet form onto the pizza shell in a uniform thickness layer. The distribution roller system in one embodiment of the apparatus includes a single roller formed with a plurality of conical projections arranged in angularly spaced axially extending rows for receiving the sauce from the waterfall dispensing device and revolved at a speed to throw the sauce in a generally downward direction in a shower of droplets. Another embodiment of the apparatus includes a pair of these rollers revolved in opposite directions and disposed in a generally horizontal plane with the second roller intercepting sauce thrown horizontally and upwardly from the first roller and then throwing the collected sauce in a downward direction resulting in confinement of the band of dispersion. A shield is provided in combination with the second roller to aid in the confinement process. In a further embodiment of the ap…
