Abstract :
The hybrid sun drying method combines sun
drying with additional heating, namely LPG. So that the
drying process can take place more quickly and effectively.
The three drying methods that will be compared are Open
Sun drying, solar dryers, and solar hybrids. The open sun
drying operation is carried out using only direct sunlight.
The solar drying operation was carried out using a solar
dryer without additional heating, while the drying
operation with a hybrid solar dryer varied the drying
temperature at 40, 50 and 60 °C. The results showed that
the average moisture content of corn grains was 13.95%
for 10.5 hours, 13.75% for 6 hours, 13.65% for 7 hours,
13.45% for 5 hours, and 13.65 % for 4.5 hours in Open Sun
drying, drying without additional sunlight. heater, and
solar drying hybrid with temperature variables of 40, 50
and 60oC. The average drying rates were 0.212 g/minute,
0.364 g/minute, 0.318 g/minute, 0.439 g/minute and 0.477
g/minute. The results of the thin layer modeling show that
the Two Term model is the most accurate and suitable
model for describing the drying characteristics of corn
grains for all variables.
