Because of the versatility of twin-screw extruders, flaked or expanded products made from various grains are easily produced in the same plant using the same twin-screw extruder, barrel configuration and ancillary equipments upstream and downstream. This article describes the main components of a complete line built around the twin-screw extrusion technology, including a raw-materials handling and premix station, preconditioning, twin-screw extrusion, tempering and flaking, toasting/drying, coating, and packaging. It also describes the versatility of the twin-screw extrusion technology and its ability to produce a wide variety of products in terms of shape, texture, bulk densities, taste, and colors.
