**Extrusion technology** is a manufacturing and food processing method in which raw materials are **forced through a specially designed die under controlled temperature, pressure, and shear** to produce products with specific shapes, textures, and compositions. In the food industry, it is widely used for making **snacks, cereals, pasta, pet food, and textured protein products**, while in other industries it is applied to **plastics, rubber, and metal shaping**. The process involves feeding raw material into an **extruder** with one or two screws, where it is **heated, mixed, and pressurized** before being forced through a die and subsequently **cut, expanded, or dried**. Extrusion offers **continuous high-volume production**, uniform shapes and textures, versatility with different raw materials, and improvements in **digestibility and shelf life** of food products. Its adaptability and efficiency make it a key technology in both food and industrial manufacturing.
