Shea butter processing using traditional technology and tools faces several challenges which are among others: physically demanding, low productivity. With respect to that, women are very often subject to heat and pain. The objective of this study is to construct manual rotary roaster and the manual stove roaster and evaluate their technical efficiencies. Technical efficiencies of the two new manual roasters tools compared with the traditional cooking pot are evaluated on the basis of following parameters: hourly capacity; technical capacity; thermal balance; work duration; water content of shea almond; extraction rate. Results showed that the rotary roaster has a throughput of 24.5 kg/h against 22.3 kg/h for the stove roaster and 9.41 kg/h for the traditional cooking pot. The needed time to cook 25 kg shea almond was 1.02 Man-Hour (MH) for the rotary roaster against 1.12 MH for the stove roaster and 2.65 MH for the traditional cooking pot. The roasting temperature reaches 118 °C in the stove roaster against 115 °C in the rotary roaster and 114 °C in the traditional cooking pot. The water content of the roasted almonds was 5.3% for the stove roasters against 5.65% for the rotary roasters. Women who were involved in the experimentation estimate that manual roasters are highly efficient because they are fast and protect against the heat and the smoke. |
