Grain drying turned upside down Use fans only at night | Throw what you thought you knew about drying grain out the window BY KAREN BRIERE REGINA BUREAU
MELVILLE, Sask. — Farmers can dry their binned grain more quickly by running aeration fans only at night, new research has found. That contradicts decades-old wisdom that suggested fans should run continuously until grain is dry.
In fact, that practice can actually damage grain by heating it and adding water to the kernels, said Ron Palmer, a retired University of Regina professor, who is best known for developing auto steering. About 18 months ago, Palmer began looking at data gathered in 2007 in Saskatchewan at the Indian Head Agricultural Research Foundation.
The information recorded bin temperature and relative humidity hourly, but it had never been analyzed. “It shocked the hell out of me,” Palmer told farmers gathered at an IHARF seminar. “This is too weird to make up.” The combination of temperature, relative humidity and grain moisture are all at play, but Palmer said it comes down to the basic idea that
drying is occurring if more moisture is leaving the bin than entering. “By using a black box approach, we don’t really care about all the complications that are going on inside that bin,” he said. “The only thing we’re concerned about overall is are we taking water out of that bin or not.” access=subscriber section=news,crops,none
