Mathematical Model for Residence Time of Cut Tobacco in Rotary Cylinder
摘要
Abstract
The residence time of cut tobacco in a rotary cylinder was studied with an in-house cold state experimental platform,the variations of residence time at different rotating speeds and inclination of the cylinder,air velocities,cut tobacco infeed rates and moisture contents were investigated separately.Basing on Friedmam-Marshall model,a mathematical model for predicting cut tobacco residence time was developed by introducing moisture content as a correction factor and the incorporation of all influencing factors,and the developed model was validated.The results showed that:1) The moisture content in tobacco was an important factor in the determination of residence time of cut tobacco in a rotary cylinder,however,it was exclusive of the conventional predicting model.2) When the conventional model modified with moisture content was used to predict the residence time of cut tobacco,the deviation between predicted value and tested value decreased,while the precision of model increased.关键词
