Most plastics processors know the basic pillars of resin drying — temperature, airflow, time, and dew point. But what’s actually happening inside a drying hopper is far more complicated than most people realize. In Novatec All-In #105, Conrad Bessemer, Greg Washburn, Tim Noggle, and Joshua Belisle dive deep into the science behind resin drying and how modern simulation tools are helping turn decades of industry “black magic” into measurable, visualized engineering. Topics discussed include: • Why all dryers are NOT created equal• The hidden importance of delivered airflow• Why airflow velocity matters more than most processors think• The relationship between pressure, airflow, and heat transfer• Why inconsistent airflow creates inconsistent resin• The difference between air temperature and actual resin temperature• How CFD and DEM simulation tools reveal what’s happening inside the hopper• Why simply hitting “-40 dew point” doesn’t guarantee optimal drying• The real challenge of achieving uniform, consistent dry resin This episode also explores how Novatec is using advanced engineering simulation technologies to better understand airflow, particle movement, heat transfer, and drying efficiency across a wide range of resin drying applications.
