Steam injection into a thermoplastic extrudate as it leaves an extruder followed by mixing of the steam with the extrudate to raise the temperature and moisture content of the extrudate and lower viscosity forms a suitable product from a thermoplastic dough at an increased output. This is accomplished by extruding a thermoplastic dough, adding steam through an injection means into the extrudate as it exits from the extruder followed by mixing of the steam with the extrudate using a mixing means. The steam injection means and the mixing means are located in an enclosed transfer means between the extruder outlet and the actual outlet of the product from the enclosed transfer means. The increased output may be handled by any suitable recovery means.

A process for producing a food by extrusion at an increased rate comprising: (a) forming a thermoplastic dough having a moisture content sufficient to render the dough extrudable; (b) extruding the dough through an orifice to form an extrudate having a temperature when it exits the extruder low enough to cause steam to condense thereon; (c) injecting steam into the extrudate as the extrudate exits the extruder; (d) admixing the steam and the extrudate to thereby condense at least part of the steam to water and uniformly distribute the water throughout the extrudate to thereby raise the temperature and increase the moisture of the resulting processed extrudate; (e) shaping the resulting processed extrudate into the product; and (f) recovering the product.
