    Watermelon fruit contains large quantities of seeds, and these seeds are under-utilized. It contains a reasonable amount of oil (22%) which if expressed will serve as vegetable oil for human consumption or biodiesel for powering agricultural machines and boost the income of the farmers. The main objective of this research work is to study the interaction effect of operating parameters on the mechanical oil expression from the seed. The variables considered include applied pressure (85.00, 90.00, 95.00, 100.00 and 105.00 kN/mm2 ), roasting temperature (70.00, 80.00, 90.00, 100 and 110 °C) and moisture content (6.00, 8.00, 10.00, 12.00 and 14.00 %). A total sum of 20 batch experiments were carried out and the maximum oil yield was 13.49% (at corresponding moisture content of 6.00%, roasting temperature of 85.00 ⁰C and applied pressure of 105.00 kN/mm2 respectively) and minimum oil yield obtained was 9.41%. (at corresponding moisture content of 14.00%, roasting temperature 80 °C and applied pressure of 85.00 kN/mm2 respectively). While the optimum oil yield of 12.42% was obtained from the expression at corresponding moisture content of 6.00%, roasting temperature of 80.00ºC, and applied pressure of 105.00 kN/mm2. The result showed that the three independent variables had significant effect on oil yield and regression model equation was developed to predict the oil yield from watermelon seeds at known variables.

    SELECTED ENGINEERING PROPERTIES OF PALM NUT (ELAEIS GUINEENSIS) REQUIRED IN THE DESIGN OF PALM KERNEL-SHELL SEPARATOR.
    (Published by Faculty of Engineering and Technology, Ladoke Akintola University of Technology, Ogbomoso, Oyo State, Nigeria., 2020) Akande, F. B; Ogunremi, I. O; Ola, F.A; Balogun, A. L; Busari, R. A
    Based on high dependence of many companies on palm kernel products for soap making vegetable oil and body cream, an efficient palm kernel-processing machine is therefore not only necessary but also important to regenerate the production of palm kernel oil in order to meet up with the ever increasing demand for the industries. Therefore, the knowledge of engineering properties becomes very important in the design of suitable and appropriate palm kernel-shell separator. The parameters investigated were linear dimensions, arithmetic mean and geometric mean diameters, surface area, sphericity, true and bulk densities, angle of repose, drag coefficient and terminal velocity of palm nut and kernel at 7.19 % and 9.5 % (d.b.) moisture content, respectively. The results revealed that average arithmetic mean diameter, geometric mean diameter, sphericity, surface area, angle of repose, drag coefficient and terminal velocity were 20.88/12.55 mm, 20.08/12.41 mm, 0.69/0.84 %, 104.67/485.31 mm2, 19.33/19.17 °, 1.93/1.22and 5.72/3.21s m/s, respectively for nuts/kernel seeds. Some of the properties of the palm nut have been determined and found useful in the design and construction of palm kernel shell separator. These properties were needed as input to models or predicting the behaviour of agricultural produce in pre-harvest, harvest, and post-harvest conditions, to aid better understanding of processing and design of machines.
