Beschreibung
Zusammenfassung:	A gel reduction device 1 of the present invention includes a gel reduction mechanism 8 provided in a polymer flow duct 5 in which a polymer kneaded compound flows and adapted to reduce gel present in the polymer kneaded compound. The gel reduction mechanism 8 includes at least one or more squeezing flow paths 10 having a flow path cross-sectional area smaller than the polymer flow duct 5, and a squeeze ratio S1/S2 of the squeezing flow paths 10 is set to be 25 to 180 so as to be able to generate an extensional flow in the kneaded compound flowing in the squeezing flow paths 10.
