Today in 1972, US Patent 3647473 A was issued, an invention of Peter Michael Howlett, and Keith Christopher Stowell, for their “Malting Grain.” Here’s the Abstract:

A process and apparatus for dehusking cereal grain by a dry mechanical method at a temperature not above about 105 DEG F., and wherein the moisture content of the grain is above about 8 percent by weight in order to damage the grain so that substantial rootlet growth is prevented without substantially damaging the aleurone layer. The dehusked grain is subsequently malted and there are advantages compared with conventional malting of husked grain.
