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

    摘要： An extruder configured to extrude a solid raw material containing moisture includes a barrel, a hopper coupled to one side of the barrel, a discharge port, a screw, vent disposed between the hopper and the discharge port to discharge vapor generated within the barrel; and a heater mounted on the barrel to heat the raw material. Raw material introduced into the barrel through the hopper is heated by the heater while being transferred within the barrel through the screw. A kneading zone, in which raw materials transferred by the screw threads are compressed, is formed on the screw. Since the raw material is melted within the barrel, a heating temperature of the heater and an axial rotation speed of the screw are controlled so that a sealing membrane that shields an inner transverse section of the barrel is formed from the liquid raw material in the kneading zone.

    摘要： Mixing and plasticating machine (100) for continuous conditioning processes, comprising: a housing (10) in which a hollow interior (18) is formed that is delimited by the interior peripheral surface of the housing (10) and extends in the longitudinal direction of the mixing and plasticating machine (100); a screw shaft (12) which extends through the interior (18) of the housing (10), rotates in the interior (18) of the housing (10) during operation and simultaneously moves translationally back and forth; a drive which rotates the screw shaft (12) during operation; and a filling device (36) arranged on the housing (10), for feeding at least one starting material into the interior (18) of the housing (10), the filling device (36) extending through a cut-out (42) that extends through the housing wall (40) or being connected to a cut-out (42) that extends through the housing wall (40), the filling device (36) comprising at least two cavities (54, 54′) that each extend over the height of the filling device (36), which cavities are separated from one another by at least one separating wall (52, 52′).
