Abstract: The primary objective of this work presents the drying kinetics of forced convection solar dryer aided with evacuated tube collector for chemically untreated red apple under the climatic conditions of Thanjavur, India. The outlet temperature of evacuated tube collector (59 – 108 ̊C) is found to be much greater than the ambient temperature (33.5 – 35.5 ̊C). This enhances the rate of drying in the evacuated tube collector based solar dryer. It takes 5 hours for apple to reach the equilibrium moisture content whereas it takes 8 hours for natural sun drying. The quality of the dried sample is observed to be better. The use of conventional fuel is minimized and the dryer is found to be eco – friendly.
