  • Fully automatic pressure batch type process operation. Automatic dosing of raw material.

  • Expander design provides efficient operation for EPS

  • High throughput yielding more processed beads per pre-expander, providing lower operating and capital cost.

  • Vacuum conveyance of raw material to upper storage hopper.

  • Stainless steel raw material storage and weighing hoppers.

  • Transparent raw material dosing funnel allows visual inspection of material flow.

  • Transparent expansion chamber enables visual monitoring of the material expansion.

  • Variable speed, stainless steel agitator stirrer with Teflon wipers insures delicate bead treatment while in the expansion chamber.

  • Live steam, controlled by a pneumatic proportional slide valve using an I/P positioner for remote control via the HMI, is introduced into expansion chamber through vent plates in bottom door. Direct steam contact on raw material provides uniform expansion of beads.

  • Purge valve on expansion chamber allows continuous cross flow of steam through raw material for more uniform temperature throughout the expansion chamber.

  • Photoelectric eye senses pre-expanded bead level in chamber which stops the expansion process at a known volume to assure precise density control.

  • Quick evacuation of expanded beads through fully open expansion chamber bottom.

  • Fluidizing bead drying bed allows precision cooling and stabilizing of expanded beads.

  • Manually adjusted weir at discharge end of drying bed allows infinite adjustment of bead residence time according to required moisture content and output volume.

  • Screen type bead de-lumping system.

  • Blower and  enture vacuum transport system provides gentle conveyance of fresh beads to local storage site.

  • Programmable logic controller containing fully functional integrated software for machine control allowing operator easy and simple adjustment of all process timers.

  • All process variables are entered via an operator interface.

  • Optional pre-expanded bead density monitoring system.
