shows the measured values of each pile. It is observed that solar greenhouse dryer piles reach less humidity in less time, being the best method for the pile 5-I-SC (Shaped cordoned), thus inside the solar greenhouse dryer, for the best pile (5-I-SC) it can reach 10% of relative humidity in 8 days, instead of the best pile outdoor reach 20% of RH this day, of course this pile has the disadvantage that occupies 8 times more surface than the others
