  • Patent number: 4275647
    Abstract: Apparatus for producing a tubular centerfilled food product having a rigid, friable baked outer shell and a core of edible filling material by a continuous, straight-through process. A semi-liquid batter having a relatively high content of mono-and/or disaccharides is carried between a pair of spaced apart heated moving surfaces and baked to form a continuous, elongated flat thermoplastic sheet having a controlled thickness. The continuous thermoplastic sheet is rolled around its longitudinal axis while warm and pliable to form a continuous tube having a closed longitudinal, non-overlapping seam. As the baked sheet is rolled around its longitudinal axis, a viscous edible filling material is injected into the core of the continuous tube as it is formed. The filled tube is cooled until the outer shell becomes rigid and is then cut into pieces of a desired length.
