Abstract

Abstract: In order to recycle and re-used waste heat during curing stage, which could achieve the purpose of energy-saving and reduce the cost of baking, ten barn building were improved at Pantong village, Zhaiji town, Kaiyang county of Guizhou province. The waste heat recycling installation of flue gas in tobacco bulk barn was designed and a contrast experiment was carried out for the baking tobacco leaves between the improved bulk curing barn and the conventional bulk curing barn. The results showed that, the improved bulk curing barn had obvious coal-saving effects of fuel consumption, its average coal consumption for 1 kg dry tobacco leaves was 1.09 kg, being 0.305 kg and 21.86% less than the conventional bulk curing barn. The improved bulk curing barn also could save the cost by 0.4 CNY each kg dry tobacco leaves, average power saving of 0.165 kW·h, the power saving rate of 18.44%, and its cost-saving rate was 20.94%. In total, it could save the cost of 160 CNY in baking every times. The appearance quality, grade structure and average price of flue-cured tobacco leaves of the improved bulk curing barn were slightly improved than those of control-cured barn. In addition,the waste heat recovery device was conducive to yellowing of tobacco leaves dry, resurgence. This recycling installation has a good promoting efficient.

Key words: tobacco, bulk curing barn, surplus heat sharing, reuse
