【摘要】 进行了过热蒸汽干燥过程物料温度变化规律的试验研究。结果表明 ,常压下无论进口温度如何 ,恒速干燥阶段物料表面的温度均为 1 0 0℃。因此 ,恒速段可使用更高的温度而不增加对物料的热损伤程度 ,而提高介质的温度可明显提高干燥速度。更多还原

【Abstract】 The experimental research on material surface temperature during superheated steam was carried out. The results showed that the material surface temperature in normal atmosphere was 100℃ during constant drying rate anyhow superheated steam temperature. A high steam temperature was adapted to raise drying rate at the meantime thermal damage of material can not be increased.更多还原
