Fig. 1 or air blower, as in active mode. The skeleton and frames of the solar collector and the dryer cabinet was
fabricated from 5cm wood thick. Solar collector of 1m long, 0.5m width and 0.1m height was mounted fixed at
30° inclined with the horizontal datum. Flexible movable drying chamber of 1 m long, 0.5 m width and 0.15 cm
height were used in this study. Polyethylene foam of 5cm thick was used as insulation material underneath the 1mm
thick Aluminum absorbing metal material. Aluminum sheet of 1mm thick with dimensions of 1m x 0.5m was used as
absorbing material. Matt black paint was applied to the absorber plate paint. One absorbing plate was used for
the solar air collector and another one with the same dimensions and material was used for the drying cabinet
A glass pane of 4mm thick with dimensions of 0.5 x 1.0m was used as a transparent cover; another pane with the
same dimensions and thick was used for the cabinet cover to intensify the incident solar flux on the drying product.
Meanwhile two slabs of 0.10 x 1.0 m were used for the collector side. The dryer cabinet sides slabs were, each of
0.15 x 1.0m dimension and it were used as hatch or window to spread the dried materials and collect data within the investigation.
