A food extruder uses a rotating screw inside a temperature-controlled barrel to convey, compress, heat, and cook raw material before forcing it through a shaped die. In direct expansion (puffing) extrusion, the rapid pressure drop as the cooked starch exits the die causes moisture to flash to steam, expanding the product. The expanded extrudate is cut by a rotating knife at the die face to the required piece length. In low-moisture extrusion (below 20% moisture), the product expands strongly and is immediately dried; in high-moisture extrusion (30–70%), the product does not expand and is used for texturised vegetable protein (TVP), meat analogues, and pet food. After extrusion, most snack products pass through a conveyor dryer (to reduce moisture and develop crispness) or a fryer (for fried extruded snacks), followed by a seasoning drum and packaging.
Single-screw versus twin-screw extruders
Single-screw extruders use one rotating screw and are best suited to processing dry, starchy raw materials such as corn grits, wheat semolina, and rice flour into simple expanded shapes (puffs, rings, sticks). They are lower in capital cost, simpler to operate and maintain, and widely used in Africa, Southeast Asia, and other markets where corn and grain-based snacks dominate. Twin-screw extruders use two intermeshing screws (co-rotating or counter-rotating) and offer substantially greater flexibility: they can process raw materials with higher fat, sugar, or moisture content; produce co-extruded filled products; create a wider range of textures; and are required for high-shear processing such as TVP and meat analogues. Twin-screw extruders are the standard for industrial breakfast cereals, pet food, texturised protein, and premium snack ranges. They cost more to purchase and maintain but offer greater product range.
