Giant Portable Crop Dryer GRAIN DRYERS Grain Dryers (29E) 20-1-21 We spotted photos of this striking-looking machine in a recent issue of Two Cylinder Magazine (P.O. Box 219, Grundy Center, Iowa 50638) and decided to find out more about it. Two Cylinder shared the photos and some archival Deere information.
The space-age looking machine was a first-of-its-kind pto-driven portable crop dryer that burned LP gas to dry corn, hay, grain, or peanuts, according to a 1959 Deere & Co. brochure.
"The Model 88 Crop Dryer has a capacity of from 200,000 to more than 4 million BTU's per hour," the brochure stated.
A big 34-in. dia. fan provided up to 37,800 cfm and had adjustable pitch blades to meet varying crop drying requirements. The dryer had two thermostats - one for high-limit safety shutdown, the other to keep drying air temperature constant.
Three 18-in. deep wagonloads of shelled corn could be dried from 30% moisture to market grade in about 2 1/2 hours. Oats could be dried from 20% moisture to safe storage level in about 1 hour. Wheat, sorghum, and barley, 1 1/2 hours. Four wagonloads of baled hay at 40% moisture took 12 to 14 hours.
The dryer required at least a Deere 430 tractor to power it.
