Extrusion is a very common process in the food industry, in animal feed but also in the plastics industry.
The extruder takes the form of a sheath in which an Archimedes screw turns.
The product is incorporated by gravity into the screw then is compressed and heated using one or two endless screws.
The CROIX company has been manufacturing single-screw extruders for over thirty years. We also design preparers and maturation tanks to be installed upstream of the extrusion process.
