Kevin Eichorn of Eden Prairie, Minnesota, has found a radio frequency that can be used to dry grain.
It requires no heat, but electricity to generate the radio waves and run a fan to blow water out of the grain bin.
He explained that the radio waves separate water molecules from grain and from each other so they can be easily removed with air movement generated by a fan.
It dries grain from the inside out whereas heat works from the outside into the grain kernels.
But the system is expensive to install, so it only pays over time. The electricity costs less than propane in his area of the United States, he said.
He markets his invention as Dry Max Solutions.
