<p>The Hohenheim type solar dryer was invented by the Hohenheim University of Germany. Professor B.K. Bala, Department of Farm Power and Machinery, BAU, Mymensingh, Bangladesh was developed and constructed this dryer with locally available material in the country. This dryer was used for drying fruits, vegetables and fishes. In this paper the jackfruit juice were dried in four experimental runs. The total 22.60 kg of fresh juice were dried in two ways; 15.16 kg was dried inside the dryer and another 7.44 kg was dried in the open sun light outside the dryer. The moisture contents for both cases were 76.84% (wb). The dried weights of jackfruit leather were 3.42 kg and 2.62 kg with moisture contents of 13.23% (wb) and 26.47% (wb) respectively after 3 to 4 days of drying operations. The temperature raised 10^o C to 39^o C over ambient temperatures at the range of solar radiation of 0 to 350 W/ m². The moisture removal rates were 124.96 gm/hr by the dryer and 65 gm/hr from the sample kept outside the dryer. The jackfruit juice for first three runs were extracted by the electric blender machine and the juice for run 4 by traditional hand method used. The dried leather from electric blender machine was seen more attractive. This study was done in Farm Machinery work shop, BAU, Mymensingh in 2002.</p>
