65 results about "Extrusion cooking" patented technology

Extrusion cooking is a short time process in which food (feed) material is cooked by a combination of temperature, moisture, mechanical shear and pressure, as it is forced through a die. 1 As products exit the die, the release of pressure causes them to expand in different shapes, based on the die geometry.

Method and apparatus for producing fully cooked extrudates with significantly reduced specific mechanical energy inputs

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. In preferred forms, the extruder (10) includes specially configured, intermeshed extrusion screws (18, 20) and a plurality of obliquely oriented steam inlets (48, 50), and an upstream, dual-shaft preconditioner (90) is used having individual variable frequency drives (98, 100) which allow infinite variablility in the speed and rotational direction of the preconditioner shafts (94, 96).
