Abstract

Extrusion machine, esp. for the food industry has >2 material-ad ancing screws inside a barrel, a feed opening for raw material, and material outlet spinnerets provided in the downstream base of the barrel in the axis of each screw. Each spinneret has an outlet core separated from the conical point of the screw by an annular conical space converging towards an axial channel itself prolonged by a diverging space up to the material outlet orifices, that are distributed regularly in two series, each centered on the axis of a screw. Good control over the pressure on the prod. up to the machine outlet, and thus good homogenisation of e.g. starch contg. superheated steam.
