The drying process of paddy in a cross-flow heat pump dryer with a stirring device to mix paddy was studied.The influence of temperature and drying rate on quality and the specific energy consumption was investigated.A falling drying rate period was visible during heat pump drying.The result showed that it took about 7.5h to dehydrate 300kg of fresh paddy from moisture content of 25% w.b.to 14% w.b.Meanwhile,the specific energy consumption during the drying process was 2022kJ/kg water,and the crack addition...
