<p>An apparatus and method for making center-filled chewing gum, in which product having up to at least 35-40% by weight of center fill can be produced. The apparatus comprises an extruder barrel and nozzle arrangement (11) which extrudes a tubular rope of gum (G) through an annular orifice (30), and at the same time supplies a center-fill material (F) to the hollow interior (V) of the tubular rope through a central nozzle (20,21) concentric with the orifice. The center-fill material (F) is fed into the hollow interior (V) of the gum rope (G) at a rate sufficient to just fill the void produced in the gum rope (G) as it is extruded through the nozzle (20,21), and without exerting a compressive pressure thereon. With this apparatus and method, center-filled chewing gum can be produced with up to at least 35-40% by weight of center-fill material and at the same time uniform wall thickness and consistency for the center-filled product can be maintained.</p> |
