In this study solar energy supported, swirling flow new drying system is designed and artificial drying of
grapes grown around Elazığ/Turkey is investigated. With the developed swirling flow dryer with airy solar
collector it is examined that drying occurs homogenously and lower moisture values are obtained in when
compared with classical drying system. Also it is found that with an increase in the drying air velocity
decreases drying time. When air directing elements are placed inside drying chamber and rotating element
to the entrance, it is examined that drying time gets shorter compared to that of natural drying. Thus, drying
time which is 200 h in natural conditions decrease to 80 h with an air velocity of 1.5 m/s with the developed
solar energy supported swirling flow dryer.
