The pasta is produced in a small commercial fresh pasta machine using an extrusion die. The machine mixes and kneads the raw materials to form a dough. The dough is pushed through the die, with the holes in the die forcing the dough to twist out naturally under high presure. An automatic rotating knife in front of the die cuts the pasta extrusion into short spirals. The die can produce about 600 bags of fresh pasta every hour. Pasta is an important source of carbohydrate in the diet. Made by Pasta Reale.
