Research on the Fragmentation Rule during Cut Tobacco Processing
In order to explore the law of broken cut tobacco during processing,different widths and lengths of cut tobacco were designed,and the structural changes of cut tobacco before and after the key processing links such as roller,fluidization and mechanical transportation were studied.The results showed that with the process of cut tobacco processing,all specifications of cut tobacco were broken continuously,the characteristic size of cut tobacco decreased,and the degree of breakage increased,mainly the mass fraction of cut tobacco with longer sizes of>7.10 mm and 4.50-7.10 mm decreased significantly,and the mass fraction of cut tobacco with<2.00 mm increased continuously.The difference of cut tobacco quality fraction of 3.35-4.50 mm was the largest among different treatments.The change rate of cut tobacco mass fraction in the process of drum processing was large,among which the process of drum drying was the largest,followed by the processes of vibration conveying,lifting conveying after drying and wind conveying,and the processes of wind cleaning and lifting before drying were smaller.After the whole processing,the characteristic size variation of 1.0 mm width cut tobacco,1.0 mm width apocoptic cut tobacco,0.8 mm width cut tobacco and 0.8 mm width apocoptic cut tobacco reached 1.86 mm,1.09 mm,1.65 mm and 1.08 mm,respectively,and the crushing degree reached 33.51%,26.35%,33.39%and 27.43%,respectively.The cut tobacco with larger feature size of>7.10 mm and 4.50-7.10 mm and narrower cut tobacco width is more likely to be broken during processing,so the quality change law of specific size of cut tobacco should be paid attention to according to the needs of processing,and the structure regulation and process optimization of tobacco should be carried out within the scope of raw material consumption.
