  • Patent number: 4450131
    Abstract: This relates to a die assembly for extruding tubular casing films wherein there are counter-rotating die members. One of the die members is mounted for shifting relative to its base under the influence of hydrodynamic pressures of the flowing extrudate so as to be self-centering relative to the other die member. This provides for a high shear cylindrical area leading into the die orifice which is of uniform thickness and which will provide for uniform fiber orientation due to the zero runout of the rotating dies.

  • Patent number: 4446167
    Abstract: The invention relates to the formation of basic smoke flavorant and colorant from natural liquid smoke and food casings and food products utilizing the basic smoke. In accordance with the invention, the known acidic liquid smokes which are formed by contacting burning wood smoke with water are neutralized with an alkaline material to form a precipitate and the addition of alkaline material is continued until at least a portion of the precipitate returns to solution. The alkaline smoke solutions are suitable for impregnating regenerated cellulose sausage casings such that during cooking the meat is colored. The invention solutions form a casing that is storage stable after impregnation.

  • Patent number: 4436625
    Abstract: A method for removing residual cresidine from impure p-cresidine sulfonic acid which impure p-cresidine sulfonic acid contains from above about two parts per billion to about 1500 parts per million of cresidine. The method comprises contacting an aqueous solution of the impure p-cresidine sulfonic acid with sufficient liquid hydrocarbon of from five to eighteen carbon atoms for a sufficient time to extract the cresidine from the p-cresidine sulfonic acid to a concentration of less than two parts per billion of cresidine in the p-cresidine sulfonic acid.

  • Patent number: 4417368
    Abstract: This relates to the filling and forming of food product units such as sausage links, wherein a flowable fill is introduced into a shirred casing through a conventional filling head and wherein a controlled underfilling of the preselected circular cross section casing is automatically maintained by modifying the cross section of the casing from circular to oval. In this manner the required underfilling of the casing is automatically effected so that the necessary space for the product fill is automatically supplied to permit the necessary crimping and twisting of the casing to define links of uniform size and weight or other changes in volume due to processing. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

  • Patent number: 4390490
    Abstract: This relates to the formation of sausage casings formed of a fibrous tube by penetrating the tube or web with viscose. A specific coating and extrusion die is provided together with a statement of the discovery that where there is laminar flow the penetration of the viscose is not controlled by the orifice size per se, but by the relative application of the viscose with respect to a column of viscose passing through the same orifice at the same rate.

  • Patent number: 4317805
    Abstract: A method of removing hydrogen fluoride from gaseous mixtures of hydrogen fluoride and hydrogen chloride, which contain up to about 5 percent by weight of hydrogen fluoride, is described. The method comprises initially contacting the gaseous mixture with a particulate, substantially anhydrous, bed of alkaline earth metal chloride material, for example, calcium chloride, to produce an effluent gas mixture having a substantially reduced hydrogen fluoride content. The effluent gas is then contacted with a secondary treatment bed of particulate, substantially anhydrous, alkaline earth metal chloride material, for example, calcium chloride, to produce a product gas containing less than 20 ppm of hydrogen fluoride. The temperature of the secondary treatment bed is maintained in the range from about -20.degree. to about +20.degree. C., and, more preferably, in the range from about 0.degree. to about 5.degree. C.
