Equally important is that bags should be opened individually and immediately loaded into a hopper dryer
. Opening several bags to allow air conveyors to transfer the resin to the hopper as needed allows the resin to pick up moisture.
This classification shows that a part of the enthalpy rise can in principle be realized outside the (twin-screw) extruder by using preheating equipment such as an oven or a hopper dryer
(assuming that the pellets will not stick together when coated with additives, and remain free-flowing at increased temperature).
To extend the life of the desiccant bed and retain its efficiency, an after-cooler is necessary to cool air returning from the hopper dryer
to the drying unit.

That is based on estimates that the IRD dryer uses 33% less energy than a conventional crystallizer, while the buffer hopper dryer
uses 74% less than the larger companion dryer that would ordinarily be used.

market is likely to grow owning to the growing demand of hopper dryers
in the well-established and emerging regions, technological advancements, and the growing penetration of the end-use industries.
[USPRwire, Fri Dec 07 2018] Hopper dryers
are also called hot air dryers, and they make the perfect choice for eradicating moisture from the surface of pellets of non-hygroscopic resin, before melting them.
