Although, outside temperature did not change so much, temperature in the collector part of the solar dryer varied in accordance with solar irradiation. Solar irradiation values ranged from 585 to 950 W/m2. The highest value for solar irradiation was recorded at 13:00 while the highest temperature in the collector was at 15:00. Air temperature in solar collector was almost the same during solar-assisted spouted bed drying experiments.
