PROCESS AND APPARATUS FOR DEPOSITING AND SPREADING PIZZA SAUCE ONTO A PIZZA BASE

摘要

An applicator head (2) in a housing (3) has a lower sauce-engaging porous metal plate (10) and an upper plate (11) which define an air chamber (13) therebetween through which compressed air is passed from an inlet (14) to exit through the porous metal plate. A block (4) in the housing (3) is spaced-apart from the upper plate (11) to define a sauce chamber (18). Nozzles (25) lead from the sauce chamber (18) to deliver sauce through a plurality of outlet openings (21) in the porous metal plate (10). Sauce is deposited in a plurality of spaced-apart separate dollops which are spread by compressed air across the face of a pizza base (50). The applicator head (2) may be rotated to further spread the sauce.
