DOME-EX System

The DOME-EX System provides continuous wet granulation/pelleting of pharmaceutical powder blends for subsequent tableting.

The unique features of the DOME-EX allow it to continuously produce micro-granules of uniform diameter and hardness. This continuous processing concept eliminates the need for slow, batch granulation (e.g. high shear, and fluid bed granulators), and yields a streamlined, high capacity, more consistent (minimal variability) process.

The DOME-EX System:

  • Dry mixes
  • Feeds (meters)
  • Wet mixes (kneader)
  • Extrudes
  • Dries continuously

Pre-blended powders are continuously metered into the DOME-EX using a powder feeder (sold separately).  Liquid is added using a peristaltic pump. The DOME-EX twin screws intimately knead/mix the material and transport it continuously into the inlet of the vertical extruder equipped with a dome die.  The wet mass is gently wiped though the dome die producing fine, dense, cylindrical granules of a specific diameter. The prepared wet material is manually fed.
