    Determination of Selected Physical Properties of Fluted Pumpkin Seed (Telfairia Occidentalis) Related to Machine Design
    (University of Ilorin, Nigeria, 2016) Odewole, MM; Adesoye, OA; Adeyinka-Ajiboye, O; Shadare, OA
    Some engineering parameters needed in the form of physical properties of fluted pumpkin seed to design, construct and analyse processing, storage and handling machines/facilities are not readily available. Therefore, this study was done to determine the following physical properties of the seed for three different varieties: size (major diameter, intermediate diameter and minor diameter), mass, surface area, volume, density and geometric mean diameter. Mature pods (13 weeks old) were procured from the National Horticultural Research Institute (NIHORT) Ibadan, Nigeria and were classified as NHTo-1, NHTo-2 and NHTo-3 by NIHORT. One hundred (100) seed samples were selected from each variety after sun drying to an average moisture content of 67.734% (wb). In summary, the following range of mean values (± standard deviation) of results were obtained: major diameter (29.968 ± 2.146 mm – 37.320 ± 2.867 mm); intermediate diameter (9.184 ± 2.061 mm – 31.020 ± 3.892 mm); minor diameter (5.421 ± 3.757 mm – 37.156 ± 2.859 mm); mass (0.992 ± 0.236 g -7.870 ± 1.318g); volume (4.400 ± 1.653 mm³- 8.399 ± 0.600 mm³) x ); density (0.136 ± 0.125 g/mm³- 2.010 ± 0. 827 g/mm³) x ); surface area (1013.16 ± 534.552 mm2 – 1584.788 ± 197.61 mm2), and geometric mean diameter (22.267 ± 1.402- 25.359 ± 2.873 mm). The values of physical properties obtained are relevant in designing machines for the handling, processing, packaging and storage of fluted pumpkin seeds.

    Determination of Some Mechanical Properties of Ugu Seed (Telfairia occidentalis) in Relation to the Design of Cracking Machine.
    (Wollega University, Ethiopia, 2015) Odewole, MM; Adesoye, OA; Shadare, OA
    Ugu (Telfairia occidentalis) seeds contain valuable Before the oil can be extracted, it has to pass through some processes like depoding, size reduction, cracking etc. The parameters needed in form of seed to design and construct the processing, storage and handling equipment are not readily available. Therefore, this study was done to determine the following mechanical properties; force at break, energy to break, strain at varieties of seeds (NHTo-1, NHTo-2 and NHTo Research (NIHORT) Institute Ibadan, Nigeria were used. 50 samples from each variety were selected at moisture content 67.734% (wb) and use (Testometric M500-100AT, 100kN) was used to determine all the mechanical properties. Result showed that the range of mean values at different orientations of diameters were as stated in the brackets: on the major diameter, for 224.857±129.892N); energy at break (0.097±0.044Nm to 0.526± (2.209±0.841% to 11.079±6.672%) and stress at break (0.133± 0.837 N/mm²). On the intermediate diameter, th to 2043.857±1050,785 N), the energy at break was (0.520±0.054 Nm to 2.604± Nm), the strain at break was (3.739 ±1.345% to 35.069± (0.225±0.111 N/mm² to 2.040±0.964 N/mm²). On the minor diameter, t was (53.500± 47.964 N to 363.857±107.606 Nm to 1.040 ± 0.548 Nm), the strain at break was (1.909± the stress at break was (0.412±0.421 N/mm gave the best crack and did least damage to the kernel on the minor diameter with the mean values of force at break of 53.500±47.964 N.
