Design and Development of Solar and Infrared Dryer
Keywords:
Solar dryer, Infrared dryer, Chili dryingAbstract
The development of the solar and infrared dryer with ventilation comprised installing a solar module and battery for electricity storage and supply. There were assemblages of infrared lamps and reflectors, a 60–degree tilt, to the dryer for supporting low solar radiation. The experiment was Chinda chili drying by the ventilated solar dryer with the infrared heaters 650 and 1,150 W. The initial moisture contents of chili peppers were 320.08–285.47 %db., and final moisture contents were 19.99–14.41 %db. Assessing dryer performance and energy consumption, dried Chinda chili from the solar dryer with the ventilation fan could decrease the moisture in the drying chamber. The drying time by solar was longer than by infrared. As a result of drying with infrared heaters 650 and 1,150 W, the higher infrared power showed decreased drying time, increased thermal efficiency, and lowered specific energy consumption.
