11485298 · 2022-11-01 · ·

A planetary roller extruder section forms a feed part of an extruder. The planetary roller extruder has an internally toothed housing and an externally toothed central spindle disposed centrally within and at a distance from the housing. Planetary spindles are arranged to rotate in a void between the central spindle and the housing. Each planetary spindle has an external toothing meshing with both the housing and the central spindle. At least one planetary spindle has two axially spaced areas with less than a full set of teeth. Those axially spaced areas include a first area having a first number of teeth and a second area having a second number of teeth. The second number of teeth is less than a full set of teeth and more than the first number of teeth.

KNEADING APPARATUS WITH FIRST AND SECOND EXTRUDERS

A kneading apparatus includes a processor, and a 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.

SAPONIFIED ETHYLENE-VINYL ESTER COPOLYMER COMPOSITION, AND PRODUCTION METHOD THEREFOR

An EVOH resin composition excellent in inorganic compound dispersibility and a method of producing an EVOH resin composition excellent in productivity and inorganic compound dispersibility are provided. The EVOH resin composition contains an EVOH resin (A) and an inorganic compound (B), and has a crystallinity of not lower than 36%. The EVOH resin composition is produced by: feeding an EVOH resin (A), an inorganic compound (B) and water (C) into a kneading apparatus including a screw-type side feeder (3); melt-kneading the resulting EVOH resin mixture while driving the screw-type side feeder (3); and expelling water vapor from the screw-type side feeder (3) to reduce the water content of the EVOH resin mixture to lower than 5 weight % while suppressing leakage of the EVOH resin kneaded body from the screw-type side feeder (3).
