  • Patent number: 7022357
    Abstract: A method of preparing smoke-impregnated tubular casings is described. The process comprises: (a) providing a tubular casing having interior and exterior surfaces, the tubular casing being selected from cellulose fiber tubular casings and synthetic tubular casings, and the tubular casing being suitable for encasing food fillings having a form selected from one of liquid and paste; (b) applying to the interior surface of the tubular casing a mixture comprising, (i) liquid smoke, (ii) browning agents, and (iii) optionally water; (c) allowing the mixture to remain in contact with the interior surface of the tubular casing for at least 5 days; and (d) optionally shirring and watering the mixture treated casing. The smoke-impregnated tubular casings prepared in accordance with the method of the present invention are suitable for liquid or paste-like food fillings, such as sausagemeat emulsions.

  • Patent number: 6395356
    Abstract: Regenerated cellulose food packaging film, including fibrous food casings which has modified cling properties for packaging sausage products. The cellulosic food casings have a fibrous reinforcement impregnated with regenerated cellulose composition which contains from about 0.01 to 2.5 weight percent of admixture of a viscose solution and a food grade cationic resin adhering agent and from about 0.001 to 2.5 weight percent of a protein. The film is prepared by impregnating a tubular fiber reinforcement with a viscose composition containing the resin and protein. The impregnating composition is applied in a single step by injecting the resin and protein into the viscose solution before being extruded into the fibrous web. This assures both even distribution of the polymeric adhering agent and protein in the web, as well as maintenance of a constant level of polymer and protein being applied during the coating process.

  • Patent number: 6283846
    Abstract: An apparatus for applying liquid smoke to the outer surface of an extruded sausage strand has a frame with an elongated stationary outer tube thereon. A rotatable tube is concentrically mounted within the outer tube. Power components are on the frame for extruding a meat emulsion through the inner tuber while it is rotating, and for winding a strip material into a casing on the outer tube wherein the formed casing slides and rotates as it progresses down the stationary tube to receive meat emulsion from a discharge end of the inner tube. A fluid, such as liquid smoke, is introduced between the rotating casing and the rotating strand of meat, which rotate in the same direction and at the same speed to prevent any turbulence from developing in the meat emulsion. A meat strand linker creates the extruded strand into links. A conveyor takes the link strand to a heating station for cooking.

  • Patent number: 6264541
    Abstract: What is described is an apparatus for stuffing casings or similar receptacles with paste, in particular with sausage meat or other foods in the form of paste, using a portioning means (16) that stuffs adjustable portions of the paste through a stuffing horn (14) into a casing (62) of a pre-defined caliber or caliber group, wherein said casing is pulled portion-wise during stuffing from a casing holder (casing brake 24). A guide tube (26) is disposed after and as an extension to the casing holder (24), the internal diameter of said guide tube 26 being approximately the same as the smaller outer diameter of the pre-defined casing caliber and/or the pre-defined casing caliber group, such that the guide tube 26 has a coating of lubricant on its inner surface and that the casing is pulled into and through the guide tube 26 in the process of being stuffed.

  • Patent number: 6056634
    Abstract: Apparatus for applying a thin liquid coat to muscle meat comprises a conduit of generally constant cross-section along which the muscle meat is forced under pressure. The conduit has an entry port for the introduction of the liquid, and fixed structure is provided for promoting the relative movement of the meat chunks within the conduit to cause the liquid material to be smeared over the surface of the meat chunks. Suitably the fixed structure comprises at least one zone wherein the cross-section differs from that of the conduit. The cross-section of the zone may be characterized by one or more of an increased cross-section area, or by a decreased cross-sectional area, or by a different aspect ratio. The liquid may be one part of a two part settable adhesive; the other part of which is applied to the meat separately from the one part.

  • Patent number: 5019012
    Abstract: The encased product of the present invention comprises an elongated flexible casing cylindrically shaped substantially along its length and having opposite end closures. A product material fills the cavity formed by the flexible casing and maintains the casing in a cylindrical shape. The cylindrical casing is formed from a elongated strip of flexible material having opposite side edges, the strip being formed into a finished tubular casing with the side edges of the strip within each casing frictionally overlapping and engaging the side edges thereof. The product is formed by continuously applying an elongated flexible ribbon to the outer cylindrical surface of a stuffing tube at a canted angle with respect to the longitudinal axis of the tube and rotating the flexible ribbon at the point where it is applied to the stuffing tube so that it will wrap around the tube in a plurality of helical revolutions to form a cylindrical casing on the tube.
