Continuous Flow Grain Dryer
"Lots of people come to see it and several have also built their own," says Walter Glynn, Delhi, Ontario, happy with his home-built continuous flow grain dryer
Glynn decided to build his own dryer after pricing used dryers. Using all new parts, except for the fan and burner, he estimates his total cost at $4,000.
The dryer combines features from commercial units with Glynn's own ideas. Corn is augered into the top of the unit and divided into two streams. The corn falls over perforated metal sections through which warm air is forced. Glynn explains that his dryer can dry 100 bu. of corn from 30% moisture down to 17% in one hour. He notes that larger capacity dryers could easily be built.
The bin is 17 ft. tall, and 5 ft. wide. The drying columns are each 8 ft. long, 1 ft. wide and 10 ft. tall. He built the sides of the drying columns from perforated metal that's commonly used in bulk kiln floors to cure tobacco.
One energy saving feature of the dryer is that air from the heating columns is recycled through flexible tubing back to the fan. The thermostat on the unit controls the unloading motor so corn can't be fed out until it has dried down to the proper moisture.
