Abstract
On an extruder for extruding foodstuffs a cutting means consisting of rotatable blades (36, 38, 40, 41) is provided. With the aid of these blades an extruded strand emerging from the nozzle (12) can be cut off or structured at the surface. The cutting blades are driven synchronously.
Claims8
Apparatus for extrusion of foodstuffs comprising an extruder screw for feeding the material to be extruded, a nozzle head having a nozzle opening and a cutting means for treating the extruded material, characterized in that on the nozzle head (10, 80) a plurality of cutting blades (36, 38, 40, 42;
- 92, 94) are rotatably mounted and that the cutting blades are led past the nozzle opening (12, 82) with one said cutting blade being movable over the entire nozzle opening and with each remaining cutting blade being movable over the nozzle opening only at the periphery.
Apparatus for extrusion of foodstuffs comprising an extruder screw for feeding material to be extruded, a nozzle head having a nozzle opening and cutting means for treating the extruded material, said apparatus being characterized by four shafts disposed about said nozzle head and rotatably mounted relative thereto via bearings in at least one bearing plate, a first toothed wheel fixedly mounted to each said shaft, a first toothed belt in engagement with the respective first toothed wheels such that movement of the first toothed belt effects rotation of each said first toothed wheel and the corresponding shafts, a second toothed wheel securely mounted to one said shaft, a second toothed belt in engagement with said second toothed wheel, a drive unit in engagement with said second toothed belt for effecting movement of said second toothed belt and corresponding rotation of each said shaft, and a cutting blade mounted to each said shaft for rotation therewith, said cutting blades being dimensioned to be led past the nozzle opening upon rotation of the respective shafts.
