An agricultural scientist at Purdue University aims to change that. Klein Ileleji has developed two technologies for drying food quickly and hygienically. The first is the Dehytray, a food dehydration tray with a protective cover that concentrates solar energy for faster drying times. The second is the Dehymeleon, a solar dryer that can hold 10 Dehytrays, and that can store extra solar energy for use as a power generator at night.
