Evaluation of material uniformity in cigarette spinning process

  • Received Date: 2021-09-14
  • The product of sugar-base ratio and potassium content in tobacco samples was used as the property value,and the normal distribution test of sample property value in cigarette making process and the calculation of tobacco mixing uniformity were conducted. Through the analysis of control chart, process capability index and tobacco mixing ability, the quality stability and variation law of tobacco in each process were explored. The results showed that the mixing uniformity of tobacco in loose moisture regain process was 67. 04%, the coefficient of variation was 32. 96%, and the mixing uniformity was poor. Premixing contributed the most to the improvement of tobacco mixing uniformity, with the variance reduction index of 17. 59 after first-order feeding premixing, and the tobacco mixing uniformity reached 94. 30%. The processing quality stability of tobacco materials in loose moisture regain and primary feeding premixing process was poor. The mixing uniformity of tobacco materials in the subsequent four processes was more than 95%, and the process capability index CP value was close to 2. 0. The processing quality stability was better. According to the results, the mixing uniformity and quality stability of the material could be improved by increasing the number of cigarette cutters and increasing the premixed cabinet in the cigarette making process.
