ABSTRACT:
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.
