A laboratory scale forced convection mirror booster based solar dryer was designed & developed for drying red chilli (Capsicum annum) under the climatic condition (Composite Climate Zone) of Malwa region , Indore ( Latitude-22.44°N, Longitude-75.5°E) of Madhya Pradesh, India. The Solar dryer consists of a box type absorber & drying chamber enclosed with glass cover, fitted with one fan operated by a photovoltaic module. The north face of the dryer was kept insulated, and having door to load and unload material in trays. The experimental results show that reduction of drying time of chillies was nearly 83% in comparison to open sun drying. The average time required to dry 1.5 kg chillies from moisture content of 89.09% to 4.36% on wet basis was found to be 16 hours.
