Closed/Expired: Increasing the Bulk Density of Powders Innovation challenge

Increasing the Bulk Density of Powders Innovation challenge

Manufacturers have been known to label containers with statements such as, “Product sold by weight, not by volume.” or “Contents may settle during shipping and handling.” Consumers may also be advised to mix the powder or to shake the container for best results before using. To improve product uniformity and improve consumer perception related to fill volume in container, the Seeker desires new ways to minimize changes in bulk density of powders from time of manufacture until consumer use.

The bulk density of a given powder sample is the ratio of it mass to its volume. Upon tapping the sample, the bulk density increases due to the removal of air, allowing the powder to settle and reducing the total volume. Bulk density is primarily affected by the size and distribution of the powder particles, moisture content, and temperature. As part of the manufacturing process, powders undergo aeration to improve the flow of the product during the filling stage. Canisters are filled to 90% of capacity and then packaged, shipped, and sold. During this time the powder settles, making it appear as though some of the product is missing when the canister is opened. Therefore, the Seeker desires a method to minimize changes in bulk density of powders from time of manufacture until consumer use.

This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker.
