Khan's Solar Food Dryer was designed by Mr. Muhammed Yasin Khan, who lives in Chichawatni, Pakistan. He has been involved with several solar cooking related projects.
His solar food dryer uses a proven technique of stacked open trays, with the upper trays stepping back to allow for maximum light. Additional heat is gathered via a lower solar collector in front. The dryer is accessed from the rear through hinged doors and vented with electrical fans in front.
