The subject of the invention is a method and installation for manufacturing a composite food product using an extruder comprising at least one screw 20 driven in rotation inside a barrel 1. According to the invention, at the exit of the first treatment zone I formed by the extruder, the material is firstly passed into a second zone II limited by a second barrel 5 equipped with bores 50-51 separating the material into several independent flows A, B..., each flow being subjected to a particular treatment, then the independent flows A, B..., are grouped together again into a single flow in a third zone III formed by a die 6 comprising at least one extrusion channel 60, the extrusion conditions being determined so that, in the extrusion channel, the independent flows are applied to one another and are joined together. The invention makes it possible to produce composite products extruded from the same material and using the same machine, and applies especially to the cooking/extrusion of food products. <IMAGE> |
