  • Patent number: 5830746
    Abstract: An apparatus for growing anaerobic microorganisms is provided having a dish top that contains a sealing ring upon which the media surface in the dish bottom rests when the apparatus is inverted. The contact between the sealing ring and the media surface forms a seal that traps the gas in the headspace between the media surface and the inside of the dish top. A oxygen reducing agent can also be incorporated into the media together, in some instances, with a substrate which react with oxygen in the media and with oxygen in the headspace thereby creating an environment suitable for growing anaerobic, microaerophilic and facultative anaerobic microorganisms.

  • Patent number: 5811146
    Abstract: Methods are disclosed for producing substantially flat processed meat products and, more specifically, flat casingless hot dogs. In the disclosed methods a material containing substantial amounts of the meat protein is formed prior to cooking into a flat form of a predetermined thickness by pressing the uncooked material. The flat form is then heated either simultaneously with the forming or thereafter to a temperature and for a time sufficient to congeal a sufficient amount of the protein to stabilize the shape of the flat form but insufficient to cause any substantial rendering of the material. The surface of the congealed flat form is then treated by smoke, drying or both to establish its texture and flavor, and the treated flat form is then finally cooked into the food product. The flat form is cut into discrete flat shaped patties either at the beginning of the method or subsequent to cooking or chilling.

  • Patent number: 5795610
    Abstract: The invention provides a molding apparatus and process of molding formable materials which comprises at least one supply manifold for receiving a formable material and plungers or pistons for applying pressure to the formable material within the manifold. A mold plate including at least one mold cavity is driven between fill and discharge positions, with the at least one mold cavity selectively exposed to the supply manifold when in the fill position. A clamp member is positioned adjacent the mold plate when in the fill position, and pressure is applied on the clamp member to clamp the mold plate against the supply manifold. The clamp member and associated structure apply pressure to the clamp member compensating for deflection of these structural members which maintains the mold plate in firm clamping relation relative to the supply manifold.

  • Patent number: 5792498
    Abstract: A method for processing a food product is disclosed which overcomes problems associated with coagulation of food products (mostly meat products) undergoing aseptic processing. The method coagulates the food product prior to aseptic processing. The coagulated food product is then separated into smaller particles using various methods. The food product is then subjected to aseptic processing and packaging. The method is especially applicable to thawed meat products such as lamb or beef. The method allows for the aseptic shipment of food products to overseas markets where previously the food product had been frozen to prevent spoilage during shipment.

  • Patent number: 5792497
    Abstract: A cheese processing machine includes an extruder assembly for forming the cheese into a string. The disclosed assembly has two extruders each forcing a different type of cheese in a plastic state into separate chambers of an extrusion head. The extrusion head has a series of apertures with each one communicating with both the first and second chambers, wherein cheese from each chamber is extruded simultaneously through each aperture to produce a string with both types of cheese. The extruded cheese string travel along brine filled troughs while a tube over each trough directs a plurality of brine streams which strike each cheese string and apply a torque which twists the string lengthwise. The cheese cools as it moves along the trough fixing the twisted shape of the string.

  • Patent number: 5786016
    Abstract: Dough shaping devices for shaping baker's dough pieces include a pair of cooperating shaping members, such as concave rounder bars (27) placed over a surface conveyor (16). The concave surface of the rounder bars is formed with a metal base plate (45) that includes a concave dough shaping surface (46) formed of stainless steel. Metal particles are formed on the dough shaping surface by the sputtering of metal plasma, to form a roughened texture, and a slick material, such as a fluropolymer, is applied thereover, to form a grainy but slick surface against which the dough pieces move. The grainy surface retards sliding friction of the dough pieces, while the slick surface permits immediate release of the dough from the dough shaping surface.

  • Patent number: 5783240
    Abstract: A method of producing extrudates such as high protein, high fat sinking aquatic feeds is provided wherein a high protein starting material is initially preconditioned and passed through an extruder; in the extruder barrel a zone of reduced pressure is created upstream of the die for densifying the final extrudate. Fat may be added to the starting mixture at any desired point in the process, and/or may be added as a surface coating to the final extrudate. Preferably, the method further involves measuring a density value of the extrudate such as bulk density, and adjusting the magnitude of the reduced pressure conditions in the barrel in response to such measurement.

  • Patent number: 5783241
    Abstract: A method for producing food products made from a basic alginate or pectin gel by means of gelatinization extrusion. A cylinder is extruded from an extrusion die with a predetermined section. The cylinder has a basic mixture, including a natural food ground product such as a fruit or vegetable, a gelatinizing agent: e.g. alginate or pectin and water. The cylinder is extruded directly from the extrusion outlet die into a vertically elongated receiving bath that contains free calcium ions which ensure the immediate gel setting of an outer wall of the extruded cylinder. The bath has a density such that the extruded cylinder remains free from any stress which might cause the cylinder to warp before the cylinder has sufficiently hardened.
