摘要
为改善微波松散设备的处理效果,将微波腔体分为进料端、中间区域及出料端3个区域,采用正交实验设计、极差分析和方差分析方法分析了各区的加工参数对配方烟叶的影响。结果表明:①在试验范围内,微波一区磁控管微波功率14 kW,微波二区磁控管微波功率15 kW,微波三区磁控管微波功率16kW以及微波加工时间330 s为最优方案;②采用优化参数进行微波松散,烟包平均温度降低1.4℃,烟包的片层温差降低2.3℃,松散回潮后烟叶松散率提高0.21%,碎片率降低0.17%。
In order to improve the processing effects of microwave loosening machine,the microwave chamber of the machine was divided into three sections,namely the first section（input end）,the second section（intermediate zone）,and the third section（output end）.The effects of processing parameters of each section on blended tobacco were analyzed with orthogonal experiment,extreme difference analysis and variance analysis,the results showed that： 1） within the test range,the optimal microwave powers of magnetrons in the 1st,2nd,and 3rd sections were 14,15 and 16 kW respectively,the optimal microwave processing time was 330 seconds;2） with the optimized parameters,the loosening rate of tobacco increased by 0.21%,the mean temperature and temperature difference between tobacco layers reduced by 1.4 ℃ and 2.3 ℃ respectively,and tobacco breakage reduced by 0.17% after processing.
