| The economic situation in most developing countries has left farmers and processors operating at small scale and under unhygienic environment. The productivity is often too low to justify labor and time investment. With respect to the challenges particularly associated with roasting of corn, a roaster was designed, constructed and its performance evaluated. The mechanized charcoal fuelled corn roaster consists of a frame, roasting unit, charcoal tray, air blowing unit and a power transmission system. The functional efficiency of the machine at different roasting temperatures of 100, 130 and 150 oC ranged between 88 and 94%, while the roasting capacity and roasting time ranged between 40 and 54 fresh corns per hour in 22 and 30 min, respectively.

| A bush mango (Irvingia gabonensis) nut handling machine was developed to ease the tedium involved in the cracking operation and enhance the efficiency of separating the kernels from hulls. The machine consists of a hopper, cracking unit barrel, electric motor, blower, tool frame, hull outlet and kernel outlet. It operates on the principle of impact using centrifugal force from the baffles on a spinning disc. Results of performance tests carried out using nuts at four moisture levels in the range of 7.52-20.6% (d.b) showed that percent effective cracking decreased, while percentage kernel breakage increased with increase in feed rate, moisture content and resident time of nuts in the cracking chamber. Winnowing efficiency increased with feed rate and... |
