What is weighing and filling equipment?

Weighing and filling equipment weighs a product and fills it into a bag, box or tote to a set weight. It covers bagging scales for open-mouth bags, valve bag packers, bulk bag fillers and automatic baggers. Vistasort supplies 29 weighing and filling models for bags from 2 oz to 3,000 lb.

What is the difference between a gross weigh and a net weigh bagging scale?

A gross weigh scale weighs the product in the bag while it hangs on the spout. It is simple, handles sluggish products well and costs less. A net weigh scale weighs the product in a hopper first and then drops it into the bag, so it can weigh the next bag while the last one is changed. Net weigh is faster and suits free-flowing products at high rates.

Which bag filler is best for powders?

Powders that aerate, bind or bridge need a forced feed. For open-mouth bags, the Magnum APO uses a variable speed auger and the Hamer VLR-B automates powder bagging with dust capture and de-aeration. For valve bags, the Model A air packer handles powders and mixes and the APV auger packer handles hard-to-feed products. For small bags, the TE-10 handles powders from 2 oz to 5 lb.

How many bags per minute can a bagging scale fill?

Weighing and filling speed depends on the scale, the product and the bag. Mechanical gross weigh scales fill 6 to 8 bags a minute, digital gross weigh scales up to 16, and the Hamer 600NW+ net weigh scale up to 26 to 30 per scale, or 80+ weighments a minute in multi-scale versions. Automatic open-mouth baggers run 14 to 20 bags a minute and vertical form, fill and seal machines up to 90.

How accurate is weighing and filling equipment?

Accuracy depends on the scale and the product. Electronic scales like the TE-10, TE-100 and Magnum valve packers are rated up to 0.4%, the Hamer 600NW+ to about 0.5 oz on a 50 lb bag with gravity feed, and bulk bag fillers to 0.1%. Multi-head weighers weigh to fractions of a gram.

Can a bagging scale work without electricity?

Yes. The Hamer HGB is a mechanical gross weigh scale that needs no electrical power. It fills 10 to 150 lb bags at 6 to 8 bags a minute, which makes it a good fit for seed cleaning plants, farms and remote sites.

What is a valve bag and when should I use one?

A valve bag is closed on both ends and fills through a sleeve, or valve, in one corner. The product pressure closes the valve when the bag is full, so there is no sewing or sealing step and the bag stacks square on the pallet. Valve bags suit powders and fine granular products such as cement, minerals, flour and chemicals.

Do you have equipment to fill bulk bags or repackage seed into totes?

Yes. The Magnum IBC3000 fills bulk bags from 100 to 3,000 lb, the JEM Super Sack Filler gives dust-tight filling with weight records, and the KSi BulkPack repackages seed into mini-bulk bags or boxes. The Magnum IBC2000 unloads bulk bags at the other end.

Does Vistasort install and service weighing and filling equipment?

Yes. Vistasort sells, installs and services weighing and filling equipment across Canada from Saskatoon, Saskatchewan, and can tie your bagging scale into bag closing, palletizing and pallet wrapping as one packaging line.
