For less than $2O, you can build this energy-efficient device. All you need for the project are simple handtools hammer, drill, pliers, clamps, and handsaw; inexpensive materials—string, aluminum foil, glue, and wood for a frame; and a little bit of do-it-yourself ingenuity. Free, detailed instructions are available from the U.S. Citrus and Subtropical Products Laboratory in Winter Haven, Fla., where SEA researchers designed built and tested the driver as part of a cooperative effort with the Department of Energy. The unique feature of the dryer is a low-cost, curved focusing surface that concentrates radiation from the sun just enough to dry foods but not enough to cause them to overheat or burn. The focusing surface is made ffom ordinary household aluminum foil drawn over strings held taut by a framework of laminted wood curves or parabolas. These parabolas are' glued into a framework designed to support the dryer at an angle that best catches the sun’s rays. The dryer focuses 16 sq. ft. of insolation—incoming solar radiation—onto 5.3 sq. ft. of drying surface. The dryer is covered with polyethylene (clear plastic) with slit openings arranged at the top and bottom to allow controlled air to flow upward from the base, through a perforated aluminum shelf on which the food is dried, and then -out the top. This plastic covering protects die food from dust, birds, insects, rain, and IDEAL FOR GRAIN - OR MACHINERY STORAGE LEASE IT See Your Agri Builder For Details. These Buildings Engineered for Self-Erection (Butler wilt furnish Erection and Foundation Drawings) Build a backyard solar dryer prevents the re-entry of moisture. Chemical engineer Charles J. Wagner and research chemist Richard L. Coleman (project 'leader) have simplified what might have been a difficult phase of the construction by forming the parabolic curves with thin wooden strips placed according to pattern, then glued and secured with clamps. “The parabolic aluminum reflector increases the drying rate of foods,” says chemist Robert E. Berry, laboratory director. “Some products that previously took 3 to 5 days for solar drying can be dried in 1 to 1% days. With this model, ..we have beaten the high cost of previous designs which used parabolic solarooncentratmg mirrors.” “Parabolic reflectors have been used as solar energy focusing devices throughout history,” says Coleman. “Now, as the cost of fossil fuels continues to climb, the application of solar energy is not only popular, but necessary.” CHAMBERSBURG - Ob jectives for 1982 were set at the June 4 meeting of the Franklin County Conservation District Board of Directors. One of the major changes was the district’s responsibilities under Level 5 of the Bureau of Soil and Water Conservation’s erosion and sedimentation control program.

Wagner has found that peaches, mangos, green peppers, onions, mushrooms, plantains, and grapes can be successfully preserved by home drying. Some food products need pretreatment, such as blanching and/or slicing. Coleman and Wagner have also studied the effect of focused in solation on moisture content of muscadine grape varieties, which make excellent, raisins. The researchers expect to find some differences in drying tunes bet ween fresh, deseeded, and pretreated grapes. Information on pretreatment for sundrying foods is available from the researchers, along with detailed, illustrated directions on the construction of the solar dryer.
