Optimization of Long Stem Yield in Tobacco Leaf Processing Based on DOE Analysis Method
[Objective]In order to optimize the process of long stem yield and improve the long stem yield in tobacco leaf processing.[Meth-od]Taking the middle leaf of Shaanxi-Gansu flue-cured tobacco as test materials and taking flow rate,three beating roller speed,four beating roller speed as the objects,by the principle of full factor experiments and DOE analysis method,mathematical regression models between long stem yield and flow rate,three beating roller speed,four beating roller speed were constructed.[Result]The results showed that:flow rate,three beating roller speed,four beating roller speed and interaction of flow rate with three beating roller speed had significant influence on the long stem yield,the interaction of flow rate with four beating roller speed and the interaction of three beating roller speed with four beating roll-er speed had no significant influence on the long stem yield.There was an effective regression model between long stem yield and flow rate,three beating roller speed,four beating roller speed and interaction of flow rate with three beating roller speed.When flow rate was 9500 kg/h,three beating roller speed was 650 r/min,and four beating roller speed was 750 r/min,the average long stem yield reached the maximum value of 15.2850%and the best.[Conclusion]Comprehensive comparison suggested that there is a certain regression relationship between long stem yield and flow rate,three beating roller speed,four beating roller speed,the optimal parameters of flow rate,three beating roller speed,four beating roller speed for long stem yield were determined through the certain regression relationship.
