Method and apparatus for forming a fibrous and layered structure

摘要

A method and apparatus for forming a proteinaceous mass into a fibrous and layered structure, including imparting a gross fibrous structure to the mass by passing the mass through a helical conveyor and layering the fibrous structure by extruding the same through a slot and changing the direction of movement of the mass as it emerges from the slot into an opening, the compression and extrusion being carried out at elevated temperature to heat set the mass.
