格盘套装针插式烟框的烤烟烘烤效果研究

Effects of grid plate package pin-plugging tobacco loading frame on quality of flue-cured tobacco in bulk curing barn

为了探索格盘套装针插式烟框散叶烘烤设备对烟叶品质的影响,以散叶插签装烟方式为对照,进行了下、中和上部烟叶烘烤对比试验.结果显示,框宽为500 mm的格盘套装针插式烟框设备,每座密集烤房的装烟容量在7 000 kg左右,高于散叶插签烘烤;烤房平均每h耗煤量和每kg干烟用煤量低于散叶插签烘烤,在烘烤过程中需要较大的通风量;烟框设备烘烤出的烟叶颜色和散叶插签相同,但是烟框烟叶的外形叶片平展、主脉挺直,与对照烟叶叶片弯曲形成鲜明对比;烟框烘烤的烟叶具有高的两糖比和糖碱比,在0.05水平上达到显著水平,但是中性致香物质总量含量低于散叶插签烘烤.

In order to investigate the effects of grid plate package pin-plugging tobacco loading frame （GPTF） on quality of tobacco leaves in bulk curing barn, the experiment was conducted with loose leaf curing by the nicotine-reducing stick（LCRS） as control. The results showed： I. Loading tobacco leaves of capability of GPTF whose width was 500 mm, was about 7,000 kg, far more than that of the control of LCRS. Coal consumption of per kg dry leaves and per h of each bulk curing barn with GPTF was lower than that with LCRS. II. There wasn＇ t difference between GPTF and LCRS on appearance quali- ty in color distinguish, but the leaf shape of the cured tobacco leaves of GPTP was similar to peaks in curing with flat leaves and the straight main vein. III. GPTP with higher value of the ratio of total sugar to reducing and ratio of sugar to nicotine was significantly different at P 〈 0.05. IV. The content of the neutral aroma components was less than that of LCRS.
