Cassava pulp is a waste product from the cassava starch industry. It can be used for various purposes i.e. biomass fuel, animal feed, and soil nourishing fertilizer, etc. However, to take advantage of cassava pulp, moisture removal is required to facilitate management. Therefore, the objective of this research is to study the optimum conditions for drying cassava pulp by a double drum dryer which is a type of dryer for drying viscous materials. In the study, 1 kg of cassava pulp samples with average initial moisture content of 84.55% (wet basis) were used. The drum dryer temperature was set at 130, 140 and 150oC, the distance between rollers 0.15, 0.30 and 0.50 mm and the speed of the drying rollers set at 0.19, 0.34 and 0.51 rpm. Evaluation of the drying performance of cassava pulp was made in terms of the final moisture content, the specific energy consumption (SEC), the drying rate (DR), and the drying capacity. The results showed that drying at 140oC, the distance between the rollers of 0.30 mm, the speed of 0.34 rpm are the optimum conditions for cassava pulp drying; this was reflected in the final moisture content at 8.03% (wet basis), SEC of 4.17 MJ/kg, DR of 3.00 kg/h and drying capacity of 59.85 g/min.
