干冰烟丝膨胀过程的机理研究
Study on the mechanism of dry ice tobacco expansion process
摘要
Abstract
Dry ice expanded tobacco(DIET)technology is an important process in tobacco industry,and the moisture content of DIET is an important technical index.A mathematical model for tobacco outlet temperature,return air temperature and moisture content of DIET was established based on mass and heat balance and appropriate engineering simplification after considering the change of heat transfer coefficient between two phases.The average absolute percentage errors of the return air temperature and the moisture content are 0.24%and 1.99%,and the maximum absolute percentage errors are 0.83%and 6.33%,respectively.The mathematical model can be used to describe the effect of process conditions and has good guiding significance for moisture content regulation of expanded tobacco.关键词
