打葉器框欄形狀及尺寸對(duì)打葉復(fù)烤葉片結(jié)構(gòu)的影響

摘要 ［目的］優(yōu)化打葉復(fù)烤葉片結(jié)構(gòu)，降低大片率，提升中片率。［方法］以會(huì)理B3F為供試材料，以打葉器一打四聯(lián)框欄為研究對(duì)象，研究了打葉器框欄形狀、尺寸對(duì)打葉復(fù)烤葉片結(jié)構(gòu)的影響。［結(jié)果］處理A2B2綜合表現(xiàn)較好，能有效降低大片率，提升中片率，且保持其碎片率、碎末率無(wú)顯著增加。當(dāng)采用7.62 cm框欄尺寸時(shí)，正六邊形框欄較菱形框欄，大片率顯著降低6.87百分點(diǎn)，中片率顯著提高3.90百分點(diǎn)，但是大中片率會(huì)明顯下降且碎片率、碎末率較高。當(dāng)采用8.89 cm框欄尺寸時(shí)，正六邊形框欄較菱形框欄，大片率顯著降低8.10百分點(diǎn)，中片率顯著提高5.72百分點(diǎn)，大中片率顯著下降，兩者的碎片率、碎末率無(wú)顯著差異。當(dāng)采用菱形框欄時(shí)，8.89 cm框欄尺寸較7.62 cm框欄尺寸，大片率、中片率、大中片率無(wú)顯著變化，碎片率、碎末率出現(xiàn)一定程度的下降。當(dāng)采用正六邊形框欄時(shí)，8.89 cm框欄尺寸較7.62 cm框欄尺寸，大片率無(wú)顯著變化，中片率提高2.23百分點(diǎn)、大中片率提高1.36百分點(diǎn)，碎片率、碎末率顯著下降。［結(jié)論］打葉器一打四聯(lián)打葉框欄采用8.89 cm尺寸、正六邊形框欄，能夠優(yōu)化煙葉葉片結(jié)構(gòu)，降低大片率，提高中片率，同時(shí)還能保持較低的煙葉造碎。

Abstract ［Objective］ In order to optimize the leaf structure， reduce the long particle and improve the medium particle in tobacco leaf processing. ［Method］ Taking Huili flue-cured tobacco B3F as test materials and taking the basket shape and size of first stage thresher as the object， effects of threshing machine basket shape and size on leaf structure in tobacco leaf processing were studied. ［Result］ The results showed that： the treatment A2B2 was best， which can effectively reduce the long particle rate， improve the medium particle rate， and maintain the fine particle rate and tobacco dust rate without significantly increasing. When using the 7.62 cm basket size， compared to diamond basket shape， regular hexagon basket shape significantly reduced the long particle rate by 6.87%， significantly improved the medium particle rate by 3.90%， reduced the long particle rate and medium particle rate， the fine particle rate and tobacco dust rate were higher. When using the 8.89 cm basket size， compared to diamond basket shape， regular hexagon basket shape significantly reduced the long particle rate by 8.10%， significantly improved the medium particle rate by 5.72%， reduced the long particle rate and medium particle rate， the fine particle rate and tobacco dust rate were no significant difference. When using the diamond basket shape， compared to 7.62 cm basket size， 8.89 cm basket size long particle rate， medium particle rate， long particle rate and medium particle rate were no significant difference， significantly reduced the fine particle rate and tobacco dust. When using the regular hexagon basket shape， compared to 7.62 cm basket size， 8.89 cm basket size long particle rate was no significant difference， improved the medium particle rate by 2.23%， improved the long particle rate and medium particle rate by 1.36%， significantly reduced the fine particle rate and tobacco dust rate. ［Conclusion］ Comprehensive comparison suggested that using the regular hexagon basket shape and 8.89 cm size of first stage thresher， can optimize the leaf structure， reduce the long particle rate， improve the medium particle rate and maintain low tobacco crushing.
