Design of hybrid type mixed-mode solar dryer for fruits and vegetables

For solving problems in traditional drying technology of fruits and vegetables and advancing crop product quality, a kind of fruits and vegetables dryer was designed based on characteristics of climate and agricultural products in Xinjiang province. Energy collection system, control system and drying system were designed with parameters setted and experimentation of drying grape was carried out. Comparing with the traditional drying ways, the drying time was shortened 66.7% and the rate of green-class products increased from less than 35% to 79.19%. The equipment can improve the efficiency of drying crops and promot agricualtural development of Xinjiang province.
