It is also evident that the change inmoisture content through time is quite faster in the small tray 1,
located at the entrance of the dryer, than for small tray2, placed at the end of the dryer. This fact remains
until the end of the process for the hybrid test shown on figure 2 showing that this process was not
homogenous (Mf
values in the figure). This is due to the previously mentioned situation in which the trays
were located towards the end of the dryer, making the sample have contact with the external colder air,
thus slowing down the process. On the other hand, figure 3 shows a final homogeneous process, this time
the trays were placed 0.03 m towards the middle of the dryer, causing both trays to end their process at
the same time. This was also observed throughout the rest of the tests which drying curves are not shown.
