| The use of inappropriate equipment to crack bush mango nut and obtain the kernel has adversely affected the efficiency of its processing operations. The manual method, which involves cracking the nut with stone or pestle and mortar, is not only slow and risky, but also wasteful. In order to develop appropriate processing equipment for the nut, knowledge of its mechanical properties is necessary. This study was undertaken to determine some strength properties of the nut at different moisture contents under lateral and longitudinal loading orientations, using Universal Testing Machine (UTM). In the moisture range of 7.52% - 20.6% (d.b) under both lateral and longitudinal loading orientations, results of tests showed that all the strength properties (bioyield... |

| The effect of moisture content on some physical properties of Bush Mango (Irvingia gabonensis) nut was studied at four moisture levels in the range of 7.52% - 20.6% (d.b). Results showed that the length, width and thickness of nut increased from 37.84 to 50.16 mm, 30.23 to 42.62 mm and 19.25 to 28.15 mm respectively, as moisture content increased in the above range. Nut sphericity decreased from 76.2% to 69.5% as moisture content increased. One thousand seed weight, bulk density, true density and angle of repose increased from 6.634 to 9.158 kg, 756.7 to 1095 kgm-3, 984.4 to 1095kgm-3 and 25.3 to 38.9o respectively, in the above moisture range. Static coefficient of friction on different surfaces increased in the order of fiber glass (0.378 to 0.394),... |

| This research work involves the design and fabrication of Irvingia nut cracking machines. It operates using impact technique which involves collision between the seednut and stationary wall. The procedures employed the design stage, fabrication and testing. The machine components are: impact drum, shaft, impeller (rotor), electric motor, driver and driven pulley and hopper. The cracking chamber consists of the impeller and impact drum. The seednuts were pre-treated before testing by sun-drying to improve its crackability. The machine gave a better performance at the speed of 2600 revolution per minute with average cracking efficiency, percentage kernel breakage and capacity of 88%, 17.5% and 916 nuts/hr. The improvement in the design can be achieved by... |
