The NWB, or Net Weigh Bagger, is used for bagging BBQ wood smoker pellets at a rate of 20 tons per hour into open mouth bags. It is a great solution to accurately fill bags to a set target weight of 25 – 60 pounds.
This system is designed to pre-weigh the material before discharging into the bag. This allows the system to weigh out the material while the operator is placing an empty bag on the fill spout. Once the empty bag is spouted, the operator will depress the foot switch to discharge the contents of the weigh hopper into the bag.
The filled bag is then released and drops onto the bag closing conveyor where a hot air sealer will close the top.
This system could also be set up with duplex net weigh bag filling machine to achieve filling rates near 20 bags per minute.
For lower packaging rates, we recommend using the GWB or GB bagging machines.
