<P>PROBLEM TO BE SOLVED: To provide a multi-stage thermoplastic resin extrusion apparatus, which is capable of producing recycled resin having higher quality, by substantially perfectly removing volatile components included in the recycled resin. <P>SOLUTION: In the multi-stage thermoplastic resin extrusion apparatus A including a first thermoplastic resin extrusion machine 10 and a second thermoplastic resin extrusion machine 60 into which molten resin extruded from an extrusion port of the first thermoplastic resin extrusion machine flows, a resin extrusion port 50 of the first thermoplastic resin extrusion machine 10 and a resin intake port 71 of the second thermoplastic resin extrusion machine 10 are connected by a connection 100 allowing the molten resin to pass therethrough without being brought into contact with ambient air, and a depressurization chamber 120 is formed in at least part of the connection 100. <P>COPYRIGHT: (C)2012,JPO&INPIT |
