ABSTRACT:
A device for expelling the gas liberated within a viscous-material treating apparatus such as a kneader, an extruder or the like. The device basically consists of a cone-shaped rotor and a cone-shaped cover member covering the rotor. The cone-shaped rotor is provided with volute protrusions on its coned surface, while the cone-shaped cover member is provided with a gas exhaust orifice to which a vacuum system is to be connected. With the cone-shaped rotor kept rotating, the volute protrusions act so as to prevent the viscous material from being swallowed up together with the liberated gas to be pumped out.
