Application

Packaging System

Meters a repeatable dose per cycle into weigh hoppers and bag fillers at up to 60 cycles per minute.

Pain points

Dose drift as the hopper empties
Pocket fill depends on head pressure, so batch weights drift as the bin runs down. A helical rotor gives a near-linear output per revolution and the drive is trimmed to within 1 % of setpoint.
Breakage of fragile product
Fast rotors break product against the knife edge at the discharge. A shear-protector profile with tip speeds below 0.5 m/s keeps breakage low.
Bridging in the small feed hopper
A narrow inlet and steep cone bridge over, so the last 20 % of the hopper will not flow. An oversized rectangular inlet with vertical walls at the pocket entry keeps it moving.

Standard drop-through airlock for gravity discharge and vacuum feeding.
