Analisis Kinerja Pengering Surya Tipe Rak Menggunakan Heat Absorber Pelat Gelombang dengan Aliran Udara Natural

The current study aims to determine the performance of a rack-type solar dryer. dryer uses heat absorber in form large wave plate and small which is placed collector room. dried material cassava. system used natural air flow due density differences. research was carried out by making two collectors, difference being used, one other wave. test simultaneously between dryers. In this study, results large-wave dryers with an average efficiency 9.24% had better than small-wave 7.68%. dryer, on rack 1 1.33%, 2 3.83% 3 5.93%. 1.50%, 3.88% 2.30%.
