The research looked at some selected physical properties of <I>Brachystegia eurycoma</I>, such as axial dimension, roundness, sphericity, surface area, bulk density, solid density, porosity, and volume which are essential in the design and construction of the processing and handling equipments of <I>Brachystegia eurycoma</I>. All the above physical properties measured showed some deviations from the average values which is typical of agricultural biomaterials. Solid density showed the highest deviation of 4.04 g/mm<sup>3</sup> while the volume showed the least deviation of 0.01 mm<sup>3</sup> when compared to those of other physical properties. The angle of repose increased with the increase in the moisture content with a coefficient of determination of 0.98.

The demand for plantain flour has increased in recent years due to its health benefits and industrial applications and information on the effect of drying methods on the physicochemical and functional characteristics of plantain flour in literature is limited. This present study was conducted to determine the effect of drying methods on the chemical, colour, functional and pasting properties of plantain flour were investigated. The results revealed that drying methods significantly (p&lt;0.05) affected all the parameters studied. The moisture content of the flours ranged between 8.18 – 11.50%, fibre 2.56 – 3.21%, ash 3.00 – 3.30% and carbohydrate 76.18 – 80.49%. The L* of the samples ranged between 95.90 – 96.98, while the peak viscosity ranged between 432.04 - 461.37 RVU, final viscosity 320.40 – 484.58 RVU and pasting temperature 81.25 – 83.20°C across the drying methods used. Bulk density values varied between 0.68 – 0.70g/ml, WAC between 115.5 – 149.8%, OAC between 110.55 – 115.55% and swelling power 31.85 – 3.54%. Determination of suitable drying method is necessary for production of good quality plantain flour and the result suggest that any drying method could be used to produce good quality plantain flour.

Three particular geometrical shapes, parallelepiped, cylindrical and spherical, were selected from potatoes (aspect ratio = 1:1, 2:1, 3:1), cut beans (length:diameter = 1:1, 2:1, 3:1) and peas respectively. The density variation of food particulates was studied in a batch fluidised bed dryer connected to a heat pump dehumidifier system. Apparent density and bulk density were evaluated with non-dimensional moisture at three different drying temperatures of 30, 40 and 50 oC. Relative humidity of hot air was kept at 15% in all drying temperatures. Several empirical relationships were developed for the determination of changes in densities with the moisture content. Simple mathematical models were obtained to relate apparent density and bulk density with moisture content.
