Abstract
Food products particularly of meat are extruded cased under pressure. The extrusion pressure, and the energy in the extrudate, makes the circular cross-section the only stable one on emergence from the extrusion head. In accordance with the present invention, two unstable shapes, D-shaped as described, are extruded each cased from its own extrusion head. The heads are disposed closely adjacent back to back so as to have a generally circular overall profile. An outer casing is fitted over the two heads. On extrusion the two D-shaped pieces abut one another and the outer casing to preserve their shapes until stabilized by freezing.
