Abstract
An improved rotary head extruder incorporates an auger system comprising more than one auger to create asymmetrical, substantially cylindrical extruded products having a density within the range of about 3.0 to about 6.0 lbs./cu ft. A wide variety of fine particles such as flour and powder can be successfully introduced into and conveyed within a rotary head extruder to the die assembly, where the materials are cooked to form hard, dense extruded collets with randomly asymmetrical shapes. A transition piece at the downstream end of the augers allows for continuous, uniform flow to the die assembly, where cooking takes place. Using the equipment described, raw materials other than the typically used corn meal are produced, while maintaining the desired bulk density, texture, and crunch of random extruded products.
