A descending spiral-shaped snack made by extrusion using an accessory additional to the extruding system, which enables a product or snack to be manufactured with flour of any cereal, the product having a descending spiral or whipping top shape. A conventional extruding system includes a diffuser or distribution disc for distributing the flour into a peripheral inner channel of an extrusion die, which is modified for making the strip of dough to emerge in an oblique or lateral manner, a peripheral containment element being arranged after the die, which consists in parallel tubes mounted over a disc, the tubes being coupled to the die by the near end portion thereof, while the far end portion is fastened by a disc, a hot air stream being circulated inside the tubes in a counter flow manner by intermittent pressure, which provides an intermittent resistance strength that causes the decrease and variation of the diameter of the extruded dough, which is coiled inside the wall of the perip heral containment element, the accessory including a cutting blade located in front of the disc intended to fasten the containment tubes. |
