National Geographic : 1943 Apr
The National Geographic Magazine USDA by Knell "Yes, from This Pile of Fresh Meat Comes as Much Water as You See in That Bottle!" The pile of pork weighs 60 pounds. By dehydration in a vacuum rotary dryer at Uncle Sam's Food Research Center, Beltsville, Maryland, 41 pounds of water are taken from it. Dried meat residue, like the dark pile at left, will weigh only 19 pounds. This saves weight and space in cargo ships taking food to armies and allies overseas (page 451). more pork than any year in history, and Uncle Sam is asking for a still larger number of hogs in 1943 (pages 441, 446, 453). Cows Give a Milk Lake 75 Miles Long To provide needed milk, butter, and cheese for Army, Navy, and Allied use, and still feed some 130 million civilian Americans, is one of the hardest jobs farmers now face. "How many farm cows does Uncle Sam milk?" I asked of Mr. L. A. Van Bomel, Pres ident of the National Dairy Products Corpo ration. "About 25 million. Last year they gave a lake of milk big enough to float all the navies of the United Nations-a lake 75 miles long, 150 feet wide, and 31 feet deep." "What share of our dairy products goes now to our Army and Navy, and, through Lend Lease, to our friends overseas?" "Quantities change, month to month. We're now sending overseas to our Lend-Lease friends, and to our own armed forces who are outside this country, about half our cheese; from 45 to 70 percent of all dried skim milk; 25 to 40 percent of evaporated milk; 70 to 90 percent of all dried whole-milk powder, and from 10 to 20 percent of our butter. "Then the boys in our own training camps here drink incredible tank-car loads of fresh milk. Fresh milk, however, cannot be shipped overseas; they use dried milk over there. "Much dried milk is made by a spraying process. In that method, we just turn a Niagara of skimmed milk into a hot captive cyclone that roars inside a vast iron tent. The dried milk falls to the floor like snow, and we gather it up. Mixed with water, it makes a nourishing drink that soldiers like. "You can take 100 pounds of skimmed milk and reduce it to slightly more than eight pounds by drying."
