| Abstract:
Sundrying is the main method for drying cassava chips dried in Ghana. The method is time-consuming, unreliable, inefficient and labor intensive. It is also difficult to control the quality of the dried product; contamination sometimes resulting. In this report, the performance characteristics of a wood-fired deep-bed crop dryer with a maximum capacity for one tonne of fresh cassava chips was evaluated. Comparing the dryer to sundrying, the deep-bed dryer dries cassava chips from 64.57% to 10.83% moisture content wet basis in 34 h, sundrying took 150 h to dry chips from 59.63% to 10.83% moisture content wet basis. Firewood consumption per kilogram dry matter produced decreased as the quantity of fresh cassava chips fed into the dryer increased from 250 kg to 1000 kg. | |
