  • Patent number: 7879377
    Abstract: Pet food products and methods of manufacture are provided, the pet food product comprising a helical body having a first material formed to include an outer surface, and a second material having a striping portion deposited on the outer surface of the first material and positioned to lie along a length of the first material, the pet food product optionally having a stuffing portion positioned within a cavity in the first material. Illustratively, the second material has a composition that provides lubrication during an extrusion process to manufacture the food product.

  • Publication number: 20100047401
    Abstract: A method for forming a pet food product includes supplying a basal formula to a feed section of an extruding system, passing the basal formula through the extruding system, supplying a particulate dough to the basal formula downstream of a compression section of the extruding system, mixing the basal formula and the particulate dough to form a pet food product, and forming the pet food product into discreet pieces. The formed pet food product includes an extruded basal portion and a granular portion mixed throughout the extruded basal portion.

  • Patent number: 6270820
    Abstract: A process for making a dry, stable intermediate pet food including meat includes the steps of combining a plurality of ingredients specified by a basal pet food formula, wherein the plurality of ingredients includes a slurry of meat, mixing the plurality of ingredients to form a basal mixture, extruding the basal mixture, cutting the extruded basal mixture into flakes, and drying the flakes to a moisture content of less than about 10% by weight. In one embodiment, to make a finished pet food composition, the flakes are shipped for final processing to a processing facility having finishing equipment including grinding, extruding and coating equipment.

  • Patent number: 6261081
    Abstract: An adjustable variable flow restriction element and an extruder containing the same are provided for mechanically controlling the bulk density of an extruded material. The adjustable flow restriction element is located in an extruder proximate to the die of the extruder in position to partially block the downstream flow of material through the extruder. The adjustable flow restriction element is structured to be capable of assuming one of a plurality of uniquely flow restrictive positions, where the degree of restriction of flow controls the bulk density of an extruded material. A method of mechanically controlling the bulk density of an extruded material by restricting the flow of the material through an extruder is also provided.
