    Abstract: A finisher assembly includes a finisher agitator having a spiral ribbon. The spiral ribbon includes an exterior edge that wipes a polymer fluid from an inner vessel wall of a finisher vessel of the assembly. One or more mixing struts are coupled along the spiral ribbon. An agitator ring is coupled with one or more of the spiral ribbon or the one or more mixing struts. The agitator ring and the one or more struts are recessed from the inner vessel wall compared to the exterior edge of the of spiral ribbon in close proximity to the inner vessel wall. When the agitator is rotated the one or more mixing struts and the agitator ring mix the polymer fluid without disturbing gel along the inner vessel wall or the mixing struts according to the recessing of the agitator ring and the mixings struts from the inner vessel wall.

    Abstract: A polymer finisher assembly having a finisher nozzle includes a vessel including an outlet orifice and an inlet orifice. The finisher nozzle extends through the inlet orifice of the vessel. The finisher nozzle includes an isometric barrel extending between a nozzle inlet port and a nozzle outlet port. A separator helix is within the isometric barrel. The separator helix separates a mixed flow of steam and polymer fluid and directs steam toward a barrel inner perimeter and directs the polymer fluid separated from the steam toward a helix axis and the nozzle outlet port. The isometric barrel and the separator helix cooperate to confine spattering of polymer fluid separated from steam to the melt pool and isolate an inner vessel wall of the vessel from spattering.
