A loosening device was installed above the vibration screen to loosen tangled tobacco and optimize its size composition ，and a spreader was installed at the discharge end of the proportioning weigher to avoid tobacco jam and ensure the continuity of tobacco flow. The results showed that ：1） Tobacco loosening ，the uniformity and stability of instantaneous flow were the key factors influencing the consistency of tobacco makeup in a cigarette ；2 ）After improvement ，the instantaneous blending precision reduced from 1.84% to 1.09% and the deviation of actual makeup in cigarettes decreased from 1.30% to 0.79%. Tobacco was well loosened and tobacco jam avoided ，the quality control and process control in cigarette manufacturing were effectively improved. Keywords ：Cut tobacco ；Blend
