　　Extruders are the machinery used to produce extruded petfood, (floating) extruded aquatic feeds and extruded animal feeds.
　　The extrusion cooking process, because it causes a high level of gelatinisation of starches, results in feeds with good water stability. It can produce 'expanded' floating feeds as well as sinking pellets. The process also improves the digestibility of the product. However, extrusion cookers are usually very large and expensive to purchase and operate
