体27に弁29が接続されている。The fine powdery raw material 23 supplied from the raw material supply port 22 of the cylinder 21 is plasticized and kneaded by a kneading screw 24, and a filter of an exhaust port 25 provided on the downstream side of the raw material supply port 22. Since the member 26 is provided at a position separated from the inner wall surface 21a of the cylinder 21, a certain thickness t is provided between the inner wall surface 21a and the filter member 26.
Raw material layer 23a is formed. The filter member 2
A lid 28 is provided on the cylinder 6 via a cylinder 27, and a valve 29 is connected to the cylinder 27.

題がある。In the case of the conventional degassing device, in order to operate for a long time without the filter member being clogged, the thickness of the raw material layer is 3 mm depending on the cylinder diameter.
The above is necessary. However, there is a problem that the stagnant raw material layer mixes with the raw material and exerts an adverse effect. Further, when this degassing device is used for dehydrating a rubber raw material, there is a problem that clogging is caused because microscopic voids between powder bodies are not formed unlike powder. Further, when cleaning the filter member clogged with the filler or the like, it is necessary to stop the extruder, so that there is a problem that productivity is reduced, time is lost, and time and effort for replacement are generated.
