AMES, Iowa – High-temperature grain dryers can dry grain at high speed to better accommodate Iowa’s increasing grain yields and farm sizes. However, both dryer design and management play a role in achieving maximum grain drying energy efficiency. A new publication from Iowa State University Extension addresses some of the factors farmers should consider when deciding to install new or update existing grain drying equipment.
“Managing High-Temperature Grain Dryers for Energy Efficiency” (PM 2089F) is available to download from the Extension Online Store, www.extension.iastate.edu/store/.
This publication specifically addresses energy-related dryer design and management considerations for high-temperature systems. Topics include wet grain holding capacity, drying temperature, adequate airflow, cooling, heat recovery and sensor calibration.
“Last year’s exceptionally wet harvest raised a lot of issues regarding grain drying and storage capacity,” said Shawn Shouse, ISU Extension agricultural engineer. “This fact sheet offers some tips for increasing efficiency.”
“We plan to address other grain drying topics, such as field drying and dryeration, in upcoming fact sheets,” said Dana Petersen, ISU Extension program coordinator with the Farm Energy Conservation and Efficiency Initiative.
The publication is part of a series of farm energy conservation and efficiency educational materials being developed through the Farm Energy Conservation and Efficiency educational initiative. The purpose is to increase farmers’ awareness of opportunities for improving efficient use of farm energy. The initiative also will help farmers explore alternatives to reduce farm energy demand and to improve their farms’ overall profitability in a rapidly changing energy environment.
