The extrusion adapter includes a breaker plate (16) placed between the tip (17) of the extruder screws and the pressure-equalising chamber (18). The downstream side of this breaker plate, coming before the pressure-equalising chamber, has a plane face whereas the upstream side has a recess which has the shape of a cone whose apex (opening) angle is the same as that of the tip of the screws. This breaker plate is formed by two series of parallel-axis channels (20). This extrusion adapter is intended especially for equipping a line for manufacturing products in the form of sheet (strip) by the cooking-extrusion-expansion process, in particular for the manufacture of food products. <IMAGE> |
