ligne pelletsClextral renowned twin-screw cooker-extruder with versatile integrated die-face forming and cutting devices are widely integrated in snack pellet lines. These offer significant productivity and quality advantages compared to conventional food pellet making machine, with continuous production, greater flexibility, precision thermo-mechanical parameter control and automation options to produce consistent and innovative products. 


How does a snack pellet production line work ?

Starches, fibers and liquids are introduced into a batch mixer according to the recipe for the end product and the dough is then conveyed continuously and uniformly to the heart of the twin-screw system where it is cooked, formed and cut to extrude a homogeneous and controlled product under pressure. This combined cooking, forming and cutting process in a single integrated unit is the critical advantage of Clextral system over traditional pellet making machine. Multiple shapes are produced by the die inserts at this point, including stars, wheels, cones, animals and other 2D and 3D variations. Wet pellets are then sent to a drying line where the product is smoothly dried.
