520			_aWe examined various methods of solar drying of restaurant leftovers. Open air as well as forced air drying gave bacteriologically inadequate products. We therefore constructed a solar boiler-dryer working at 105 degrees celcius. To prevent the observed heating to higher temperatures at the later stages, drying was extended to two days. While sterilization and removal of most of the water are achieved by boiling in the solar boiler-dryer on the first day, open air drying on the second day allowed us to obtain a light brown, colored product with trace amounts of bacteria and mold. The energy efficiency for vapourization was 85 percent. Heat losses of the whole dryer due to reflection, convection, and radiation were calculated to be thirteen percent, seven percent, and twenty percent, respectively. The product obtained from the mixture over five successive days had a composition close to recommended values for chicken feed (e.g., broiler).
