Sait water pond helps dry grain ARGONNE, 11. A pond of water that can store enough heat during the summer to dry a far mer’s grain crop in the fall was the subject of a workshop this week at the Department of Energy’s Argonne National Laboratory, near Chicago. Argonne has developed a system to remove heat from its ex perimental salt gradient Solar pond for use in drying grain, heating barns and houses or supplying domestic hot water. Salt water is the key to the pond’s ability to collect and store COMPARE DeLAVAL® New Century l * Series of Bulk Coolers For Performance Quality, Value AllDeLaval Coolers Feature: • 5 year warranty • All stainless steel construction • Oval enclosed for structured strength and high performance Foam-in-place insulation to keep down operating cost and maintain milk quality Dependable efficient automatic washing Wall mounted stainless steel control panel Most popular sizes available. 600 to 5,000 Gallon Capacity.

Salt concentration increases with depth, forming layers that suppress convection circulation within the pond. Sunlight penetrates the surface, warming the lower layers. Because the lower layers are heavier than those above them, they cannot rise, and their heat remains trapped. The pond can produce useful heat day and night, all year round, even when covered with winter ice. Peak water temperatures at the bottom of the solar pond exceed 170 degrees F at the end of summer, SEE GRAHAM’S DAIRY SUPPLY RD 3, Box 382 Greensburg, PA 412-834-3162 1.6. AG SALES Silverdale, PA 215-257-5136 low winter temperatures are about 100 degrees F. » The quarter-acre pond is about 12 feet deep. It holds 700,000 gallons of water and about 700 tons of salt. The heat removal system developed by Argonne uses a heat exchanger to tap the hot water at the bottom of the pond. Air passes through the heat exchanger at 8000 cubic-feet-per-minute and is warmed by the hot water to about 40 degrees above the temperature of the surrounding air. This temperature and airflow is suf ficient for grain drying operations. YPAR POUND PERFORMANCE Super Ro-Vu Clow The DeLaval® Super Flo-Vu™ milking claw is the newest thing in milking.
