Overview

Randomized trial evaluated drying performance of indirect solar dryer for dehydrating tomatoes, suggesting improved efficiency with higher solar radiation.

Key Points

This study aims to assess the efficiency of a forced convection-assisted indirect solar dryer in dehydrating sliced tomatoes.
Evaluated a solar dryer over five months, testing different air temperatures and solar radiation levels.
Loaded 10 kg of fresh tomato slices daily, drying from 9:00 a.m. to 6:00 p.m. until moisture content reached approximately 6%.
Measured direct normal irradiation (DNI) ranging from 200 W/m2 to 850 W/m2 during drying tests.
Drying time reduced from 35.5 hours in December to 19 hours in April, indicating a 46.47% reduction.
Thermal efficiency increased from 20.95% in December to 27.43% in April.
Average drying rate improved from 7.27 × 10−5 kg/s in December to 10.91 × 10−5 kg/s in April.
