摘要 [目的]優(yōu)化皖南B2F煙葉葉片復烤工藝參數(shù)。[方法] 以皖南煙葉為研究對象,對葉片復烤的關鍵工藝參數(shù)進行正交設計試驗,從葉片結構、感官質(zhì)量和含水率控制3個方面進行質(zhì)量分析,運用極差分析,并進行驗證,確立影響煙葉品質(zhì)的主次因素和最優(yōu)的參數(shù)組合。[結果]在試驗條件下,影響大中片率的主要因素是熱風溫度,隨著熱風溫度的提高,大中片率呈下降趨勢;影響感官質(zhì)量的主要因素是進料含水率、熱風溫度,其次是熱風風速、底帶頻率,進料含水率越大或熱風溫度過高、過低對感官質(zhì)量不利;熱風風速對含水率控制影響較大,風速過大,含水率控制越不穩(wěn)定;葉片復烤工序最優(yōu)參數(shù)組合為進料含水率16.0%、底帶頻率35 Hz、熱風溫度80 ℃、熱風風速30 Hz。[結論]研究可為焦甜香煙葉原料打葉復烤工藝參數(shù)設計提供一定的參考依據(jù)。

Abstract [Objective] To optimize Southern Anhui B2F tobacco leaf threshing and redrying technical parameters. [Method] With Southern Anhui as study object, the orthogonal design test was conducted on key technical parameters of tobacco leaf threshing and redrying. The quality was analyzed from three aspects of leaf structure, sensory quality and moisture control. Using range analysis to verify, the influencing factors and optimal parameters combination were determined. [Result] The results showed that: in the experimental conditions the main factor affecting the rate of large and medium-sized sheet is hot air temperature, hot air temperature increases with the large piece rate, decreased; the main factors affecting the sensory quality of feed moisture content, air temperature, air velocity, the velocity of the belt, feed moisture content is higher or the hot air temperature is too high, too low on the sensory quality of the negative; wind speed has a great influence on the moisture control, high speed wind, moisture control is more unstable; the leaf redrying process optimal parameters for the feed moisture content 16.0%, bottom frequency 35 Hz, hot air temperature 80 ℃, velocity of hot air 30 Hz. [Conclusion] The study can provide a certain reference basis for design of tobacco leaf threshing and redrying technical parameters.

葉片復烤是打葉復烤工段的關鍵工序之一,對煙葉原料的品質(zhì)構成顯著影響[1-2]。皖南煙葉作為具有焦甜香風格特征煙葉的代表,近年來,在“黃山”品牌葉組配方中起著舉足輕重的作用,其使用的比例也呈逐年遞增趨勢。目前,對打葉復烤環(huán)節(jié)的工藝參數(shù)優(yōu)化報道較多[1-3],而對于葉片復烤工序的關鍵工藝參數(shù)優(yōu)化,尤其是針對皖南煙葉的卻鮮有報道[3-4]。因此,筆者以皖南煙葉為研究對象,對葉片復烤的關鍵工藝參數(shù)進行正交設計試驗,運用極差分析,并進行驗證,確立影響煙葉品質(zhì)的主次因素和最優(yōu)的參數(shù)組合,旨在為焦甜香煙葉原料打葉復烤工藝參數(shù)設計提供一定的參考依據(jù)。
