Hopper Dryers

Hopper Dryers

The moisture in the Plastic Resins (Hygroscopic and Non-Hygroscopic) will effect the surface finish and quality of the molded component. We have designed a compact and economical HOT AIR HOPPER DRYER to overcome this problem.
Features
  • Drying capacities ranges from 25 Kgs to 100 kgs
  • Direct Machine mounting
  • Tubular type heaters for longer heater life
  • Solid state temperature controller for reliability
  • Process air temperatures to 150°C and higher with options
  • Fiber glass insulation optional
  • Low power consumption
  • Specially designed diffuser cone for uniform heating and drying
  • Detachable air distribution system for easy cleaning

Frequently Asked Questions

Hopper Dryers are devices designed to remove moisture from plastic resins before they are processed in injection molding or extrusion machines.

Hopper dryers help prevent moisture-related defects such as bubbling, poor surface finish, or structural weakness. They also enhance product consistency, cycle time efficiency, and energy savings.

Use a hopper dryer before injection molding, blow molding, or extrusion when the plastic granules are stored in humid conditions or naturally absorb moisture from the environment.

Temperature is managed by a solid state or PID temperature controller, which ensures precise and reliable heating. Some models offer thermostatic control and over-temperature protection for added safety.

A hopper dryer should be used whenever plastic resins are at risk of absorbing moisture from the environment, especially before injection molding or extrusion. This is crucial for maintaining product quality and preventing defects caused by moisture
