h shows thee results off the dryingg kinetics off mango as a first Th
sttep of prettreatment ffor biofuelss production. This method explo
oits the po
otential of the carbohydrate pressent in the raw materiial, which consists off 20 g/L of ssimple ferm
mentable suggars based o
on 10 g dry matter out of 100 m
mL of distilleed water. D
Dehydration
n was carrieed out by n
natural convvection ussing a solarr dryer. Thee dehydratio
on achieved
d 95.6% mo
oisture removal in 28
8 h and reached m
maximum ttemperaturres of 52 °C and 56 5 °C, co
orrespondin
ng to first and secon
nd phases, respectively. The minimum teemperature reached w
was 21 °C. TThis paper sshows the d
drying rate, drying teemperature, and grams water rem
moved on grams of dryy mass. Thee speed off drying waas obtained
d in the firrst stage, between b
0 to 4 hourss, with raadiation maaximums off 991 and 1014 1
W/m2
2 for that d
day. The sp
peed of drying, observed at thee peak of raadiation, waas 0.060 g H2O/ H
g dryy mass/ m
min. A solar dryer in transparent acrylic a
was used, whicch had an in
nternal vo
olume of 0
0.125 m3. TThe dehydration was performed
d through natural n
co
