Heat Capture System Saves Drying Costs GRAIN HANDLING Accessories 24-3-18 When Jerry Coatsworth put a plastic barrel around the 15 hp. electric motor on his natual air drying blower, he was merely trying to protect the motor from snow and rain. But then he got the idea of siphoning off heat from the motor to help dry grain.
Although he figures he saves just a fraction of a cent per bushel by capturing the wasted heat, he spent only a few dollars on the idea and figures the savings will add up over the years.
He estimates the heat produced by the motor at about 6,886 btu's per hour. He cut a hole in the top of the barrel and inserted a piece of 8-in. dia. non-perforated drain tile which runs up over the fan housing to the intake side of the blower. Coatsworth was careful not to restrict airflow on the intake side.
The idea won first prize in this year's Environmental Farm Plan contest which is sponsored by the Canadian government.
