Patent ID: 7951419

Claim:
A method of manufacturing a batch of oxygen-scavenging particles, comprising steps of: mixing oxidizable component particles together with activating component particles to form a mixture; compressing the mixture of oxidizable and activating component particles to force collisions between the oxidizable and activating component particles for attaching the activating component particles to surfaces of the oxidizable component particles; shearing the mixture of oxidizable and activating component particles to remove irregular accretions of the activating component on the surfaces of the oxidizable component particles; and repeating the steps of mixing, compressing, and shearing the mixture of oxidizable and activating component particles to more evenly coat the surfaces of the oxidizable component particles with the activating component, wherein the oxidizable component particles and the activating component particles have substantially different hardnesses, and the collisions between the different particle components deform at least one of the component particles.
