Sausage casing

Most of the artificial sausage casing worldwide is produced from cellulose. Cellulose, usually from cotton linters or wood pulp, is processed to make viscose, which is then extruded into clear, tough casings. They also are shirred for easier use and can be treated with dye to make "red hots". The casing is peeled off after cooking, resulting in "skinless" sausages.

Cellulosic viscose solutions are combined with wood pulp to make large diameter fibrous casings for bologna, salami, smoked ham and other products sliced for sandwiches. This type is also permeable to smoke and water vapor.

They can be flat or shirred, depending on application, and can be pretreated with smoke, caramel color, or other surface treatments.

Production of rayon fiber

The production of rayon fiber involves the use of spinning bath that are essentially composed of diluted sulfuric acid. These baths are obviously highly corrosive and shall be maintained at a suitable temperature to ensure the process efficiency.

GAB Neumann’s process equipment

GAB Neumann annular groove graphite heat exchangers, graphite heaters, graphite coolers, and graphite block heat exchangers are used for the heating of spinning bathes. GAB Neumann’s impervious graphite is an FDA approved material.
