Zusammenfassung:Single screw extruder (E) for the extrusion of food or feed, comprising in the direction of flow of a product to be extruded: a processing section (8), a bypass outlet (B), a valve plate (V), a die plate (D), and a cutter (6). The flow of product can be directed through the valve plate under normal operating conditions of the extruder, and through the bypass outlet during start-up of the extruder or for maintenance purposes downstream of the valve plate. The valve plate is arranged on or in a mounting plate (M); the cutter and the mounting plate are provided with interacting guiding means that prevent rotation of the cutter vis-à-vis the mounting plate; and the cutter and the mounting plate are mechanically fastened to each other with rotational locking means.
