不同机械调控方法和贮存楼层对片烟养护的影响

Effect of different mechanical control methods and storage floors on the maintenance of flue-curd tobacco

在湖北省选取具有代表性的武汉乐道物流有限公司醇化库,分析不同楼层(1、2、3、4楼)的环境温湿度变化,进一步分析3种机械调控方法(整仓除湿、1次/周密封烟垛除湿、1次/2周密封烟垛除湿)对不同楼层片烟在醇化过程中的相对含水率、化学成分、感官质量的影响,最终分析3种方法的能耗。结果表明,4楼的箱芯温度在高温月份比1~3楼平均高0.91~2.18℃;pH降低幅度比1~3楼平均高0.29%~0.91%;香气质显著好于1~3楼;香气量、刺激味、余味优于1~3楼。3种方法对片烟的相对含水率、化学成分和感官质量无显著影响,但密封烟垛除湿能更好地维持各楼层垛内相对湿度的稳定和一致,且1次/2周密封烟垛除湿的能耗最低且工作量最少,其为各处理中最优的机械调控方法。

The representative alcoholization storehouses of Wuhan Ledao Logistics Co.,Ltd.in Hubei Province was selected,and the changes in ambient temperature and humidity on different floors(the 1st,2nd,3rd and 4th floor)were analyzed.Then the effects of three mechanical control methods(whole storehouse dehumidification,once a week sealed stack dehumidification,once two weeks sealed stack dehumidification)on the relative moisture content,chemical composition,sensory quality of flue-curd tobacco on different floors during the aging process were analyzed.Finally,the energy consumption of the three methods was analyzed.The results showed that the box core temperature on the 4th floor was 0.91~2.18℃ higher than that on the 1st~3rd floor in high temperature months;the decrease of pH was 0.29%~0.91% higher than that on the 1st~3rd floor;the aroma quality was significantly better than that on the 1st~3rd floor;the aroma quaneity,pungent taste and aftertaste were better than those on the 1st~3rd floor.The three methods had no significant effect on the relative moisture content,chemical composition and sensory quality of flue-curd tobacco,but the sealed stack dehumidification could better maintain the stability and consistency of relative humidity in stacks on each floor.The energy consumption and workload of once two weeks sealed stack dehumidification were the lowest.Consequently,it was the optimal mechanical control method.
