Solar dryer, Dragon fruit, Mathematical modeling


The solar dryer was constructed in Loei province. The dimension of the dryer is 1.50 m wide, 4.50 m long and 1.20 m high. All sides of the dryer are covered with polycarbonate sheets. Five drying experiments for drying red dragon fruit were conducted. For each experiment, 30 kg of red dragon fruit were dried in the dryer. A system of partial different equations describing heat and moisture transfer during drying the red dragon fruit in the dryer was formulated. This system of partially differential equations was solved numerically using the finite difference method. The simulation results agreed well with the experimental data for solar drying of the red dragon fruit.
