The variations in moisture content of chilli that different positions inside the dryer compared to the control sample dried by natural sun drying were showed in Fig. 6. The moisture content of chilli in the solar dryer was reduced from an initial value of 74 (wb) to a final value of 9% (wb) within 3 days whereas the moisture content of the natural sun-dried samples was reduced to 66% (wb) in the same period. There is no significant difference in solar drying of the products in the different positions inside the solar greenhouse dryer. In addition, the chilli dried in this dryer was completely protected from insects, animals and rain.
