摘要: 氣流平移式密集烤房是在現(xiàn)有密集烤房結(jié)構(gòu)的基礎(chǔ)上，對裝煙室,、供熱室,、循環(huán)送風(fēng)道進(jìn)行重新布局改進(jìn)后形成的烤房。同現(xiàn)有密集烤房相比,，風(fēng)機(jī)運(yùn)行環(huán)境得到了優(yōu)化,，烤房內(nèi)空間得到了充分利用,，裝煙量增加，熱能利用率得到了提高,，烘烤成本有所降低,。試驗結(jié)果表明，氣流平移式密集烤房空載條件下烤房內(nèi)同層及兩側(cè)風(fēng)速均勻穩(wěn)定,，烤房升溫速度比較快,，平均為7.04 ℃/h。同密集烤房相比,，煙葉外觀質(zhì)量與等級質(zhì)量沒有明顯差異,，但裝煙量增加685.5 kg；干煙葉耗煤1.26 kg/kg,，較對照減少0.25 kg,，總耗能減少0.49 元/kg,，節(jié)能效果比較明顯,。Abstract: Air translational bulk curing barn was invented by re-arrangement of loading room, heating room and cycling supply air duct of bulk curing barn. Results showed that under the unload condition, the wind speed of same layer and both sides were uniform and stable; the temperature increased more rapidly, while heating rate was 7.04 ℃/h. The comparative test of tobacco curing showed no significant difference occurred between the two types of barns with regard to sensory quality and grading quality of tobacco leaves. However, loading capacity of the new barn increased by 685.5 kg; coal consumption was reduced by 0.25 kg/kg dry leaves. Total energy consumption was reduced by 0.49 yuan/kg dry leaves. Effect of energy saving was evident.
