Weighers

There’s a lot of concern about weight these days. It’s also a long-held concern in packaging production where precise weighing into packs or containers is needed for regulatory reasons per label declarations. Where weight control makes for healthier humans, it also makes for healthier, better-run lines. Weighing accuracy is also important because packagers don’t want to give away any more product as overfill than can possibly be achieved. Otherwise it goes to waste.

 

John Henry, CPP, notes in the “Packaging Machinery Handbook" that there are two broad, general classifications of bulk dry fillers:

 

  • Weight-based fills determine the product net weight either before or after it is in the container. If the weighing takes place in the container, it is similar in many respects to the weight fill used for liquids:  The container weight is tared and product is introduced into the container at a fairly high flow rate until it is nearly full; then the flow rate is slowed to top off to the desired weight.
  • Another technique is to weigh the product externally prior to introducing it into the container. Product is fed in to a hopper mounted on a load cell or scale, typically using a similar combination bulk-and-dribble technique.  When the hopper is full, it is dumped into the container. External weighing will be faster since the scale doesn't have to await container movement. It can be filling while the full container indexes out and the following container indexes in.
