Ugandan Student’s Invention Speeds Drying Of Fruits, Vegetables

August 14, 2018: 12:00 AM EST
A 23-year-old Ugandan engineering student has invented a produce drying device that he believes could help solve a serious food waste problem in Africa and beyond. Dubbed the Sparky Dryer, the dehydrator runs on garden waste – not electricity, which is scarce. It dries fruit and vegetables quickly so they last months instead of days, cutting down on food waste. Lawrence Okettayot’s device – starting price $80 – looks like a small refrigerator and can dehydrate 10 kg of mangoes in two hours. A small chamber contains a gas fire that heats a separate drying chamber above where the sliced produce is stacked in shelves. A catalytic converter prevents harmful gases from being released during the drying process. The device is a better option than traditional methods because it doesn’t rely on scarce electricity and can operate during the rainy season. [Image Credit: © www.Nhillfilms.com]
