A method for continuous production of extruded and/or coextruded potato and cereal flour-based snacks, including the steps of preparing a dough (D) from food flours (F) having a predetermined residual moisture, extruding the dough (D) to form one or more continuous strips (2), coupling said one or more extruded strips (2) for forming an elongate continuous semifinished product (3), extending along a substantially longitudinal axis (L), deforming in a controlled manner the continous semifinished product (22), cutting the continuous semifinished product (3) into segments having a predetermined length to form semifinished snacks (1), drying the semifinished snacks (1). After the extrusion step and before the cutting step, the extruded strips (2) are subjected to a spinning and controlled deformation action, in such a manner as to take a substantially helical shape, and to provide the continuous semifinished product (3) with a substantially twisted or multiple thread screw shape, with a wavy and spiraled outer surface (4). |
