Abstract
Abstract An apparatus for continuously producing a slab of fibrous, meatlike product in which amorphous heat coagulable dough is forwarded from a hopper by converging conveyors which induce substantially unidirectional transverse distension of the dough which distended dough, upon being heated sufficiently to induce coagulation, is transformed into a meat-like slab of substantially parallel, bonded, fibers.
