Patent number: 4470171Abstract: Disclosed is a composite casing article comprising two or more shirred casing lengths. The two lengths are arranged end to end in tandem with each rearward length in the arrangement having an unshirred portion laced through the bore of each forward length in the arrangement. This allows all lengths to deshirr simultaneously during stuffing to form a multilayered casing wall. Also disclosed is a method for making the article and a stuffing method utilizing the article to produce a food product encased in a multilayered casing.Type: GrantFiled: September 30, 1982Date of Patent: September 11, 1984Assignee: Union Carbide CorporationInventors: Jerome J. M. Rusmussen, William F. Yearout, Jr.

Patent number: H70Abstract: A method of producing a nutritionally dense, freeze dried food item usually n bar form in which uncooked food ingredients are mixed together and then cooked until about 40% to about 60% of the water content is removed by evaporation. Then the partially dried mixture is formed into the desired shape, then frozen and dehydrated to a moisture level which would produce a shelf-stable product. The freeze dried bars are packaged in impermeable containers. Food bars prepared by this method rehydrate faster and to a greater extent than food bars prepared by processes incorporating a compression step.Type: GrantFiled: April 16, 1984Date of Patent: June 3, 1986Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Daniel Berkowitz, Gary W. Shults, Agnes G. Russell
