Solar Collector Cuts Drying Cost
Under ideal sunlight conditions, the new Kern'L Komfort solar grain drying system collects upwards of 300,000 btu's of free heat per hour. Its maximum drying output is equivalent to 4 gals. of LP gas per hour, says Don Schmidt, vice president of marketing for Specialty Metal Fabricators, Minonk, Ill., manufacturer of the solar collector.
Even on overcast days it still operates at 50% or better efficiency, and also reduces rain intake through the aeration fan on rainy days, Schmidt points out. A single solar drying system handles a 10,000 to 12,000 bu. capacity storage unit. Multiple units are recommended for storage of over 12,000 bu.
The Kern'1-Komfort system has a triangular shaped, solid steel rod support frame resting on black polyethylene film which is used as the collector. Clear polyethylene film, with ultra-violet light inhibitor, is used for the cover and collector enclosure. Special patented fasteners attach polyethylene to the frame. A flexible adapter is used to fit any size fan housing and a manually operated proportional airflow control is standard equipment.
The complete unit is 100 ft. long, 8 ft. wide and 26 in. tall, providing 800 sq. ft. of collector area. When not in use, the unit stores in an 8 by 8 ft. area.
Retail cost of the 100 ft. long collector is $1395. During the off season for crop drying, it can be used to provide supplemental heat for your farm shop or other buildings. Takes about 4 hours to assemble or tear down. Estimated annual cost for replacing the 100 ft. plastic cover is right at $50, according to Schmidt.
