The optimization of cycle temperature stability for leaf feeding in cigarette production

The effects of preheat temperature, cyclic hot air temperature setting value and the P value of PID control were investigated in cigarette production based on the comprehensive evaluation which were guided by the Sigma level of cyclic temperature. The optimum conditions obtained by single factor and orthogonal methodology were as follows: preheat temperature and cyclic temperature setting value were its standard value, the P value of PID control was 500. Under these conditions, the temperature control program of WQ3318-SJ1525 was optimized, and the Sigma level of cycle temperature in leaf feeding increased from 2.0 to 3.94.
