A manually powered beater type mixer was designed, constructed and tested.
The mixer was constructed to effectively mix milled shea nut with little ef
fort and at minimal initial capital. It has a conical shape located located
inside a hemispherical mixing bowl. It has an output capacity of 120 kg/h
and the capacity of the mixing bowl at full load is 20 kg. The product obta
ined from the mixer was compared with the product from the traditional meth
od. The results of the comparative economics of milled shea mixer indicated
that the cost of mixing one tonne of milled shea nuts using the mechanical
mixer costs about $ 2.2 (N 220) as compared to $ 6.5 (N 650) for manual mi
xing. Hence, the high cost requirement of mixing milled shea nut through tr
aditional method and the high tabour requirement were considerably reduced.
