A Unique Approach to Micronization

Resonance destruction occurs when the vibration of a certain material exceeds its natural resonance frequency, such as when the Tacoma Narrows Bridge failed in 1940. This research reports the use of this resonance destruction phenomenon to process grain. In cooperation with Dr. Jeff Gwirtz, KSU, we used a Pulsewave™ Technology machine with a capacity range of 500-8,000 pounds per hour to reduce wheat grain to flour. The Pulsewave™ Technology has the ability to reduce a very high percentage of clean endosperm into flour in a single pass and thus potentially uses significantly less energy than a conventional mill. This technology causes grain to break into fractions differently than a conventional mill, and thus produces flour with different, possibly superior, quality traits.
