Extrusion of Snacks
Snacks are made from a wide variety of starchy raw materials and vary in color, appearance and taste. They are often produced on an extruder and cut directly at the nozzle.
Snack products are so versatile and varied that there is something for everyone. They come in a wide variety of shapes and colors, with different flavors and seasonings and vary in texture depending on how they are made. They often have one thing in common: they are produced by extrusion. To achieve this, various starchy raw materials can be used, which are modified in their structure by means of a twin-screw extruder and thus under the influence of temperature and shear in such a way that a snack product is subsequently created. A variety of raw materials can be extruded with a wide range of results. Extrusion technology is a process in which a material or a mixture of materials is pressed through an opening or die with a defined shape. The shear force required for this is generated mechanically via the pressure caused by the rotation of the screws.
