การออกแบบเครื่องอบแห้งพลังงานแสงอาทิตย์แบบไฮบริด

This research is to develop and experiment the hybrid solar dryer by using cultivated banana as the ingredient in the experiment. The objective is to design create and test the hybrid solar dryer that using heat energy with infrared heater. The result from the experiment of drying cultivated banana at night-time by using heat energy from infrared heater is found that at night-time experiment cultivated bananas moisture is decrease more than at day-times experiment for 61.25 %. The temperature inside the hybrid solar dryer at night when using heat energy from infrared heater is at 49.1-55.0°C. Using heat from sunlight together with infrared heater cause the cultivated bananas moisture to decrease better approximately 27 % when compare to drying with heat energy by only sunlight.
