Abstract: Butterfly type solar dryer can be use for drying various products in a rural area under hygienic conditions. Present paper deals with the drying of ginger using butterfly type solar dryer. Solar drying system was constructed, consisting of two parts (solar collector and solar drying dishes). A frame required for this experiment was made from iron or steel. It was observed that, the moisture content of ginger was reduce from 25 grams (initial moisture content ) to 3 grams ( equilibrium moisture content) within the drying period of 120 min.
