oisture removed for a given set of dryer dimensions.
In order to verify the models, experiments were performed on a prototype solar
dryer under a solar simulator at the University of Newcastle upon Tyne (UK). The
solar simulator uses Compact Source Metal Halide Lamps (Iodide) often called CSI
type. The CSI simulator is recommended for indoor testing of solar collectors and
although it does not provide the exact natural conditions, it produces radiant energy
that has a spectral distribution, intensity, uniformity in intensity, and direction close
to that of solar radiation, and is very reliable [18]. The solar simulator was set at
a constant radiation of 635.0 W/m2 and the mean ambient temperature during the
experiments was 27 °C
