Abstract
A kneading apparatus includes a processor and an extruder. The extruder includes a screw. The screw includes a screw main body. A conveyance portion, a barrier portion, and a path are provided at places of the screw main body. In at least one of the places, the path is provided inside the screw main body and includes an entrance and an exit. The raw materials, pressure on which is increased by the barrier portion, flow in from the entrance. The raw materials flowing in from the entrance flow through the path toward the exit. The exit is positioned to be remote from the entrance in an axial direction. A method of using the kneading apparatus includes continuously melting and mixing materials in the processor, using the melted materials as the raw materials, and continuously discharging kneaded materials produced by kneading the raw materials with the screw in the extruder.
