摘要: 為解決打葉復烤加工過程中因把頭未解把和煙葉過長使煙葉相互纏繞及煙葉與設備纏繞造成的堵料,、物料流量不均勻等問題,，對打葉復烤預處理段工藝進行了創(chuàng)新——把葉分離工藝。該工藝改變了以往打葉復烤工藝中對煙把進行機械或人工解把的概念,，直接將煙把把頭部分切斷單獨處理,，實現把葉分離，分類加工,。應用結果表明,，解把率可達99％以上，堵料故障停機率,、設備有效作業(yè)率顯著改善,，煙葉主要打葉質量指標得到不同程度改進，經濟效益得到提高,。Abstract: In order to resolve the problems that unloosening butts and long leaves tend to tangle together or twisted around machine, which results in jamming, tobacco flow interruption, and machine halt frequently, a process of pretreatment in the threshing and redrying line was designed and tested. This process changed the conception of manual or mechanical bundle loosening in threshing and redrying process, cutting off the butts of tobacco bundles directly as individual treatments. Some problems of the process of bundle loosening were resolved. The treatment of individual tobacco bundles by classification was discussed for improving purity of lamina and easing the load of previous process. The results showed that ratio of bundle loosening was above 99%, ratio of jamming breakdown and operation rate of machine were improved greatly, main quality indexes of threshing improved, and economic benefit increased.
