How using a vibratory compaction table can reduce packaging and transportation costs

Packaging and transporting a free-flowing dry product without first compacting it can be costly: packaging and storing the uncompacted product uses more containers and more storage space than necessary, transporting the partially empty containers raises freight charges, and in-transit settling can create voids in the containers, resulting in container damage. This article explains how you can save money by using a vibratory compaction table during packaging to compact dry product in containers before they're transported.

You've probably noticed the following label on a breakfast cereal package: "This package is sold by weight, not by volume. Some settling of contents may have occurred during shipment and handling." As the package is handled and trans- ported on its way from the production line to your table, it's vibrated, causing the uncompacted dry cereal to fall into a compact heap in the package's bottom. As more cereal falls to the bottom, a void or dead space forms in the package's top, which means that the package is larger than the product requires and consumes extra space on the grocer's shelf and in your kitchen cabinet. The package is also more likely to be damaged.
