In this paper a comparative study of drying methods in four samples of passion fruit wastes (peel and albedo) in two dryers: a solar bioreactor-dryer (BSS) and a solar tray dryer with flat plate collector (SSBCP). In two of the samples it was added molasses corresponding to 5% of the total mass. The four samples, separated two by two (passion fruit with and without molasses) were subjected to the enrichment procedure with 2% yeast species Saccharomyces cerevisiae for 24 hours in the BSS with aeration. Subsequently they were dried for 240 minutes in both driers, two in the BSS and the remaining in the SSBCP. For finishing the drying process they were placed in a oven for 50min at 80 ° C for the samples that were in the BSS and at 10 5° C for the samples from the SSBCP drier. It was observed that the samples dried in the BSS attaint final moisture of 26.07% and 12.92% for passion fruit wastes with and without molasses, respectively, whereas in SSBCP samples these values were 60.99% and 67.80% for passion fruit samples with and without molasses, all on wet basis (Xbu).
