PROCESS AND APPARATUS FOR THE PRODUCTION OF EDIBLE WREATH-SHAPED FOOD CASINGS, ESPECIALLY SAUSAGE CASINGS

摘要

Edible wreath shaped food casings are produced by a blow-extrusion method in which the inflated extruded tube is fed onto a series of rotating carrier elements whose peripheral velocity is the same as the rate of discharge of the tube from the extrusion nozzle. The carrier elements may be shaped in a variety of ways but the extruded tube is always led onto the first one tangentially. Lifting guides ensure proper transfer of the tube from one carrier element to the next. The method permits the production of thin-walled casings.
