Effect of moisture content and loading orientation on some strength properties relevant in the design of snake gourd (trichosanthescucumerina. l) seed handing device CIGR Journal
IDOWU, David Oluwafemi; Owolarafe, Oseni Kehinde.
The knowledge of mechanical properties under applied forces is very important to engineers during the design and handling of agricultural products. This study was carried out to evaluate the effect of moisture content and loading orientation on some strength properties of snake gourd (Trichosanthes cucumerina. L) seed. The strength properties measured are compressive extension at yield, compressive strain at yield, compressive load at yield, compressive load at break and energy at yield. These properties were evaluated at five moisture levels (6.3, 8.6, 12, 14, and 17% dry basis) under the three loading orientations (length, width and thickness). The results show that loading orientation has great effect on the compressive properties of the seed. At all...

A STUDY OF SOME HYDRO-THERMAL PROPERTIES OF SANDBOX (HURA CREPITANS) SEED CIGR Journal
IDOWU, David Oluwafemi; Abegunrin, Peter Toyin.
ABSTRACT Thermal properties of crops are very important in the design of drying, processing and storage equipment. The availability of thermal properties data on Hura creptance seed will assist in machine design, equipment manufacturing and the seed processing where they required heat treatment. The specific heat, thermal conductivity and thermal diffusivity of Hura creptance seed were determined as a function of moisture content which varies from 6 to 20% (d.b). The results of the experiment on the moisture content-related thermal properties were analyzed using regression analysis. The specific heat capacity of the seed was found to be in the range 0.0681- 0.2949J/Kg oC with temperature range of 40 to 80oC, while the thermal conductivity was found to be...
