Extrusion has become a common process in the feed industry and allows the production of feed
types that simply are not possible with pelleting or any other process we have available. In general,
single screw extruders provide adequate operating ranges and are more economical to operate than
twin-screw extruders. With the availability of low cost extrusion equipment, processing of oilseeds
such as soybeans is feasible. There is no doubt that the application of extrusion to the development
of new and novel feed products will continue and will result in increased usage of the technology in
the future of the feed industry.
