Drying Hoppers for Plastic Resins
Drying hoppers are part of most drying systems. They are usually sized to hold about four times the hourly throughput of the dryer they serve. At a glance, they look much the same but there are certain basic features you should look for to ensure efficient drying and processing convenience.
Full insulation is the most important feature to ensure energy efficiency. The insulation should be at least 2” thick and should be included in the cone area as well as the sides of the hopper.
