对“低温慢烤”的思考

Discusion on "Low Temperature Redrying"

烟片的“低温慢烤”来源于《低卷曲干燥》。认为烟片在复烤过程中，降低干燥段循环气流的干、湿球温度，提高冷却段循环气流温度，即可减少热冲击，减少烟片卷曲，提高回潮效率。这实际是延长烟片干燥时间、增加能耗、取消冷却段的复烤工艺，其理论依据似乎不能成立。“低温慢烤”的烟片复烤方法值得商榷。

The 'Low temperature redrying'technology reduces the impact of heat on lamina,lowers the curl of lamina, and improves the conditioning effectiveness of lamina by lowering the wet and for bulb temperatures of the circulating air in the drying zone and raising the temper- ature of the circulating air in the cooling zone during redrying. In fact, the technology prolongs the drying time of lamina, increases power consumption and removes the cooling zone in the redrying of lamina. It is suggested that the technology concept seems to be incorrect.
