TRY IT, DRY IT: The Propane Council has worked with three companies on a joint project to develop improved technology to boost the energy efficiency of grain dryers.

Fuel-efficient grain drying

New grain dryer technology provides energy savings for farmers.

The Propane Education & Research Council partnered with three different companies to develop new fuel-efficient grain drying technologies that will help agricultural operations save money. PERC invested in the research and development of GSI’s heat reclamation system, Mathews Co.’s redesigned Legacy Series grain dryers and Sukup Manufacturing Co.’s new burner design. PERC provided industry expertise and financial support through the research, development and testing process for the new technologies.

“PERC prioritizes the development of new technology that advances energy efficiency,” says Cinch Munson, director of ag business development for the council. “By working with leading manufacturers to advance efficient grain drying technologies, we can help ensure farmers operate as cost-effectively as possible.”

Saving energy saves money
Energy savings were the driving force behind PERC and GSI’s development of a new heat reclamation system for tower dryers. The reclaimer is engineered to capture air from the lower part of the drying portion, above the cooling section. It separates out the hot dry air from wet air, and carries very little chaff or other debris back into the dryer. The result is a system that saves up to 30% of propane at 32 degrees F during the drying season. The system is available now and can be installed on any new tower dryer or retrofitted to any Zimmerman-style dryer built since 2001.

PERC also worked with Mathews Co. to achieve energy savings through innovation. The firm completely redesigned the fan, burner and control system found in its profile-style Legacy Series product line. The newly redesigned profile-style dryer offers many of the same tech advantages and operational efficiencies as a tower dryer. By introducing tower dryer elements to a profile-style dryer, Mathews has created a more efficient dryer with lower operating costs.

Take control of your harvest
Sukup and PERC partnered to increase energy savings by redesigning a grain dryer burner. The highly efficient Octagon Burner uses less propane to achieve the temperature rise needed to dry grain. The result is increased fuel savings and lower carbon dioxide emissions. An added benefit is the burner’s aluminum manifold, which increases durability and longevity of the burner. All Sukup 2017 axial-fan dryers will use the new Octagon Burner. They are also available as replacement burners for older dryers.

“These new technologies result in a highly efficient, cost-effective grain-drying process,” Munson says. “Drying your own grain is more viable than ever. With propane prices remaining low, now is an excellent time to take more control of your harvest with a new grain dryer.”
