The scale hoppers receive materials by a closed-loop Aeropass system, filter receivers, cyclones or screw feeders.

Material can be delivered to the scale hoppers by a closed-loop Aeropass system, filter receivers, cyclones or screw feeders. When a receiver is used, an Aerolock meters material into the scale hopper until the set point is reached.

  • Continuous or batch weighing
  • Conveying rates up to 30,000 lb/hr
  • Recipe, formula and inventory capabilities
  • Gate valve allows scale hopper to discharge material on demand

The closed-loop Aeropass scaling system feeds multiple scale hoppers with a common material line, eliminating the need for separate filtering on each hopper.

  • 2, 3, 4 and 5 inch line sizes
  • Valve mounts directly on scale hopper, simplifying system design and cost
  • Separate conveying lines for applications sensitive to cross-contamination
  • Aeropass diverts material into the hopper until ingredient set point is reached.
  • After the set point is reached, the valve purges the material and air to the source
  • Scale hopper's unique internal scroll improves material/air separation to achieve good filling efficiency, even with fine powders
