  • METHOD AND APPARATUS FOR PRODUCING FULLY COOKED EXTRUDATES WITH SIGNIFICANTLY REDUCED SPECIFIC MECHANICAL ENERGY INPUTS
    Publication number: 20110091627
    Abstract: Improved extruders and methods for the extrusion cooking of comestible products such as human foods or animal feeds are provided wherein the products may be produced with very low specific mechanical energy (SME) inputs as compared with conventional processing. The methods preferably involve introduction of very high levels of steam into the extruder barrel (12) during processing, which concomitantly reduces necessary SME inputs required to achieve desired cook and expansion levels in the products. In accordance with the invention, fully-cooked pet foods can be fabricated with SME inputs of up to about 18 kWhr/T, whereas aquatic feeds can be fabricated with SME inputs of up to about 16 kWhr/T.
    Type: Application
