Multiple reusable tubular casing, and apparatus and process for using same in the production of caseless (skinless) parboil or raw sausages

摘要: A resuable tubular casing is made of porous polytetrafluoroethylene (PTFE) membrane for the production caseless (skinless) parboil or raw sausages. The has a micro-structure comprising PTFE nodes connected by fibrils with porosity about 70-80%, Gurley No. less than 28 seconds, Bubble Point Pressure greater 13, and Water Entry 40 psig. contacted on at least part its circumferential area support such as cylindrical lattice. new process sausage involves heating in formed reusable non-adherent, vapor permeable to drive off moisture other volatile materials, removing from casing. can subsequently be smoked reused.
