Figures 2 and 3 show the drying curves for March 6
th
and April 17
th
when the dryer operated in hybrid
mode and solar mode respectively. Both figures show the moisture content on dry basis (X), in water kg/
dry solid kg vs. drying time measured in hours. On the graph’s legends final moisture content wet basis
(Mf) for each small sample tray is shown for the total process time (t) fromtable 1; at the entrance (1) and
exit (2) ofthe dryer. The X value of moisture wet basis content of 24% corresponds to a 0.32 water kg /
dry solid kg.
