摘要
为了优化烟丝产品加香均匀性,在线试验改变加香工序的香精流量、物料流量、喷嘴数目、喷嘴位置和雾化压力,并用超声提取-气相色谱质谱联用法对加香工序引入的目标致香化合物进行定性和定量分析:当加香比例一定时,香精流量越小,致香化合物的绝对施加量越大;当香精流量和物料流量一定时,香精的雾化程度越高,致香化合物的绝对施加量越小.用主成分分析法对加香工序加香均匀性进行分析,结果显示:当香精流量为30 kg/h时,加香均匀性随着雾化程度的增高而降低;当香精流量≥50 kg/h时,加香均匀性均随着雾化程度的增高而提高.当单喷嘴加香时,停留时间长、雾化程度高,加香均匀性最优;当双喷嘴加香时,加香均匀性最优的条件为香精流量50 kg/h,物料流量4500 kg/h.
Essence flow,material flow,nozzle group and atomizing pressure were adjusted in production-experiments.Ultrasonication-extraction-gas-chromatography-mass-selective method(UE-GC/MS)were used for qualitative and quantitative tests of the samples:at determinate flavoring rate,the absolute quantity of essence in tobacco grows with essence flow rate decreasing;at determinate essence flow rate,the absolute quantity of essence in tobacco decreases with fogging degree increasing.The total uniformity coefficient calculating by principal component analysis(PCA)was used to evaluate the flavoring uniformity in tobacco primary processing.Experimental results shows that the flavoring uniformity decreased when the fogging degree increasing at low essence flow(30 kg/h);and increased with fogging degree increasing at high essence flow(≥50 kg/h).The flavoring uniformity calculation result increase with standing time and fogging degree increasing,when using single nozzle.The maximum flavoring uniformity calculation result turns up at essence flow rate of 50 kg/h and material flow rate of 4500 kg/h.
