Conclusions
The total drying time when operating in solar mode is in average 31.2% longer (2 hours) than when the
dryer operated in hybrid mode, taking into account similar conditions, especially when related to
pineapple moisture content.
Initial moisture content is a determining factor in the pineapple drying velocity. The higher the
moisture content, the longer it will take to complete the drying process.
Under similar operating conditions (last 4 from table 2) the solar mode process is almost twice as
efficient as the hybrid mode;
