FAQ: Drying

How to dry resins?

Proper drying requires attention to detail in the following areas: temperature and moisture content (dew point) of the inlet air, volumetric flow rate of the air across the pellets, time the material is in the drying hopper, and temperature of the return air coming back from the hopper to the drying unit. There are other areas of concern related to the design and maintenance of the system. This also assumes that a desiccant dryer is being used.

How can I achieve more consistent resin drying?

  1. Control Initial Moisture Levels in Undried Resin

  1. Size Dryers Properly

  1. Dry at Correct Temperature

  1. Keep Drying Hoppers Full

  1. Limit Machine-Side Material Inventory

  1. Keep Airflow Clean and Consistent

  1. Invest in a Moisture Analyzer
