A nozzle for spraying food ingredients including an inner orifice for the ingredients and an outer orifice for spray air. A piston is reciprocable in a cylinder within a housing above the orifices. Attached to the piston is a clean-out plunger that extends through an ingredient delivery tube into the inner nozzle orifice as the piston reciprocates, thereby cleaning and unclogging the inner orifice. Displacement of the piston is caused by compressed control air supplied through two air ports in the cylinder on opposite sides of the piston. Reciprocation of the piston can be initiated by a timer or by a manual override.
