Title:
PELLET PRODUCTION APPARATUS AND PELLET PRODUCTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/003773
Kind Code:
A1
Abstract:
Provided are: a pellet production method for thermoplastic resins that, even when production is performed continuously for long periods, limits the occurrence of connected pellets and pellet cut surface tails and defects, suppresses the generation of fines, and improves pellet quality and productivity; and a pellet production apparatus useful for said production method. More specifically, a pellet production method and production apparatus are provided, wherein the production method comprises, after melting a composition comprising a thermoplastic resin and an additive, a step for conveying strands obtained by discharge from a feeder with a belt conveyor, a step for spraying a liquid on the strands on the belt conveyor, a step for blowing a gas on the strands on the belt conveyor, a step for measuring the surface temperature of the strands, and a step for cutting the strands conveyed by the belt conveyor into pellets. The production method adjusts the sprayed liquid volume or liquid temperature according to the measured surface temperature of the strands.
