ABSTRACT:
A device for manufacturing expandable polystyrene (EPS) pellets includes a continuous process extruder, a die, a pelletizer and a hot water annealing quencher assembly. The pelletizer cuts strands of EPS material extruded from the extruder and die into uniform EPS pellets. The annealing quencher assembly includes a quencher tank, a water vortex substantially immersed therein for generating a slurry of water and EPS pellets discharged from the pelletizer, a quenching loop, and a slurry pump for pumping the slurry from the water vortex through the quenching loop to thereby anneal the EPS pellets.
