Abstract[Objective] To study effects of SH9 feed moisture content on tobacco comprehensive quality after drying. [Method] The change of tobacco comprehensive quality under different feed moisture content was studied. [Result] The results showed that, different feed moisture content has significant effects on tobacco, filling value and sensory quality, while has no significant effects on whole tobacco rate and broken tobacco rate. [Conclusion] The study can provide reference basis for adopting proper control parameters in tobacco processing with SHP online expansion equipment.

SH9在線高速膨脹系統(tǒng)是我國自主研發(fā)的一種煙絲干燥設(shè)備,國內(nèi)有較多應(yīng)用[1]。在卷煙加工過程中,干燥工序?qū)頍熂庸べ|(zhì)量有重要影響,一般情況下干燥工序的進料含水率、工藝氣流溫度是SH9在線高速膨脹系統(tǒng)的主要參數(shù)[2-3]。該種干燥設(shè)備在干燥煙絲過程中由于系統(tǒng)熱損失的變化,工藝氣流溫度變化明顯,在控制過程中常常通過調(diào)整進料含水率來影響工藝氣流溫度。為此,筆者研究了SH9進料含水率對干燥后煙絲綜合質(zhì)量的影響,以期為卷煙企業(yè)在用該設(shè)備對煙草加工時選擇合適的控制參數(shù)提供依據(jù)。
1材料與方法
1.1材料
長春卷煙廠生產(chǎn)的A牌號三類烤煙型配方煙絲,SH92在線高速膨脹系統(tǒng)系統(tǒng)(常州智思),InfraLab710實驗室用紅外水分儀,YDZ430智能填充值測定儀,YQ2煙絲振動分選篩。
1.2方法
在正常生產(chǎn)過程中,調(diào)整進料含水率,滿足工藝氣流溫度在標準中心(190±5)℃范圍內(nèi)波動,其他工藝指標
控制穩(wěn)定,以進料含水率為變量因素,取4個試驗水平,水平1~4的進料含水率(平均值)依次為24.50%~24.3%、2410%~24.3%、23.90%~24.10%、23.70%~23.90%,以煙絲填
充值、整絲率、碎絲率為考察結(jié)果指標,評價干燥后煙絲的綜合質(zhì)量狀況。
依據(jù)試驗要求,對所選批次煙絲在貯絲時間滿足工藝標準(4 h)后,在貯絲柜取樣(取樣時避開柜頭、柜尾300 kg,剝?nèi)ケ韺?0 cm),每批次取樣1 500 g。檢測煙絲整絲率、碎絲率、填充值,整絲率、碎絲率檢測1次,填充值檢測3次取平均值,每個水平取9批次。另每個水平選1個批次按上述方法取樣15 kg,制作品吸樣品。
2結(jié)果與分析
2.1進料含水率對煙絲整絲率的影響每個水平9個批次煙絲的整絲率見表1。對表1中試驗數(shù)據(jù)進行單因素方差分析,得每個含水率水平9個批次的煙絲整絲率平均數(shù)與標準差,Levene檢驗顯示方差齊,F(xiàn)(3,32)=1.39,P=0.264,不同
2.2進料含水率對煙絲碎絲率的影響4個進料含水率水平9個批次煙絲碎絲率見表2。對表2中試驗數(shù)據(jù)進行單因素方差分析,得每個含水率水平9個批次的煙絲碎絲率平均數(shù)與標準差,Levene檢驗顯示方差不齊,事后多重比較Dunnett T3檢驗顯示處理間差異不顯著。
2.3進料含水率對煙絲填充值的影響4個進料含水率水平9個批次煙絲填充值見表3。對表3中試驗數(shù)據(jù)進行單因素方差分析,得每個含水率水平9個批次的煙絲填充值平均數(shù)與標準差,Levene檢驗顯示方差齊,F(xiàn)(3,32)=7.57,P=0.001,方差分析顯示,不同試驗水平結(jié)果差異顯著。
2.4進料含水率對煙絲感官質(zhì)量影響
從不同試驗水平的品吸樣品與標準樣品三點檢驗結(jié)果(表4)可以看出,24.50%~24.30%進料含水率水平的品吸樣品與標準對比樣差異顯
3結(jié)論
該試驗條件下,進料含水率對煙絲加工質(zhì)量有一定影響,尤其對填充值及感官質(zhì)量影響顯著。
SH9在線高速膨脹系統(tǒng)生產(chǎn)過程中為保證煙絲質(zhì)量的穩(wěn)定,應(yīng)盡量保持進料含水率穩(wěn)定;當工藝氣流溫度有大范圍波動時,可小范圍調(diào)整進料含水率來干預(yù)工藝氣流溫度,進料含水率調(diào)整范圍不宜大于0.3%。
