ABSTRACT:
Methods and an apparatus for filling doughnuts or like edible products with a filling in which the product is extruded over and through a hollow, annular filling nozzle such that the product material flows closely past radially, outwardly directed discharge openings in the filling nozzle. The product material forms a solid annular ring where it is rejoined, and filling material is injected into the ring by applying positive pressure to the filling material in the filling nozzle. The filling flow is stopped by applying negative pressure from within the filling nozzle to draw the filling material back from the discharge openings of the nozzle. The negative pressure allows the product material to move toward the discharge openings, sealing the openings.
