The results were
mathematically modelled to show the advantages of the Solar Greenhouse Dryer for both, to reach the
10% of relative humidity and fewer days were dedicated for this. Thus, these analyses reveal that the Solar
Greenhouse Dryer is a useful and vital technology for the improvement of wood chips as biofuel, it
reduces moisture, and it can be applied in many countries because of the fact that it only uses solar
energy; it is a renewable energy resource which is both free and clean
