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(guó)自主研發(fā)的一種煙絲干燥設(shè)備,國(guó)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(jìn)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(jìn)料含水率來影響工藝氣流溫度。為此,筆者研究了SH9進(jìn)料含水率對(duì)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(duì)煙草加工時(shí)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

1.2方法
在正常生產(chǎn)過程中,調(diào)整進(jìn)料含水率,滿足工藝氣流溫度在標(biāo)準(zhǔn)中心(190±5)℃范圍內(nèi)波動(dòng),其他工藝指標(biāo)
控制穩(wěn)定,以進(jìn)料含水率為變量因素,取4個(gè)試驗(yàn)水平,水平1~4的進(jìn)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(biāo),評(píng)價(jià)干燥后煙絲的綜合質(zhì)量狀況。
依據(jù)試驗(yàn)要求,對(duì)所選批次煙絲在貯絲時(shí)間滿足工藝標(biāo)準(zhǔn)(4 h)后,在貯絲柜取樣(取樣時(shí)避開柜頭、柜尾300 kg,剝?nèi)ケ韺?0 cm),每批次取樣1 500 g。檢測(cè)煙絲整絲率、碎絲率、填充值,整絲率、碎絲率檢測(cè)1次,填充值檢測(cè)3次取平均值,每個(gè)水平取9批次。另每個(gè)水平選1個(gè)批次按上述方法取樣15 kg,制作品吸樣品。

2.1進(jìn)料含水率對(duì)煙絲整絲率的影響每個(gè)水平9個(gè)批次煙絲的整絲率見表1。對(duì)表1中試驗(yàn)數(shù)據(jù)進(jìn)行單因素方差分析,得每個(gè)含水率水平9個(gè)批次的煙絲整絲率平均數(shù)與標(biāo)準(zhǔn)差,Levene檢驗(yàn)顯示方差齊,F(xiàn)(3,32)=1.39,P=0.264,不同
2.2進(jìn)料含水率對(duì)煙絲碎絲率的影響4個(gè)進(jìn)料含水率水平9個(gè)批次煙絲碎絲率見表2。對(duì)表2中試驗(yàn)數(shù)據(jù)進(jìn)行單因素方差分析,得每個(gè)含水率水平9個(gè)批次的煙絲碎絲率平均數(shù)與標(biāo)準(zhǔn)差,Levene檢驗(yàn)顯示方差不齊,事后多重比較Dunnett T3檢驗(yàn)顯示處理間差異不顯著。
2.3進(jìn)料含水率對(duì)煙絲填充值的影響4個(gè)進(jìn)料含水率水平9個(gè)批次煙絲填充值見表3。對(duì)表3中試驗(yàn)數(shù)據(jù)進(jìn)行單因素方差分析,得每個(gè)含水率水平9個(gè)批次的煙絲填充值平均數(shù)與標(biāo)準(zhǔn)差,Levene檢驗(yàn)顯示方差齊,F(xiàn)(3,32)=7.57,P=0.001,方差分析顯示,不同試驗(yàn)水平結(jié)果差異顯著。
2.4進(jìn)料含水率對(duì)煙絲感官質(zhì)量影響
從不同試驗(yàn)水平的品吸樣品與標(biāo)準(zhǔn)樣品三點(diǎn)檢驗(yàn)結(jié)果(表4)可以看出,24.50%~24.30%進(jìn)料含水率水平的品吸樣品與標(biāo)準(zhǔn)對(duì)比樣差異顯
3結(jié)論
該試驗(yàn)條件下,進(jìn)料含水率對(duì)煙絲加工質(zhì)量有一定影響,尤其對(duì)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(jìn)料含水率穩(wěn)定;當(dāng)工藝氣流溫度有大范圍波動(dòng)時(shí),可小范圍調(diào)整進(jìn)料含水率來干預(yù)工藝氣流溫度,進(jìn)料含水率調(diào)整范圍不宜大于0.3%。
