Influence of HT Steam Flow Rate on Physical Properties of Expanded Cut Tobacco Stem
This research is to study the influence of HT steam flow rate on physical properties of expanded cut tobacco stem,adopting uniform design and stepwise regression methods to analyze the amount of the HT temperature,the moisture content of expanded cut tobacco stem,filling value,and other aspects under different steam flows.The indications are made:as steam flow increases prior to the drying process,the variation of moisture in dryer outlet is greater than the filling value,and the sample's filling value is not necessarily high with low moisture content.In the steam flow range of 150~450 kg/h,with each additional steam now of 50 kg/h,the filling value of expanded cut tobacco stem after storing increases by about 0.11 cm3/g.The filling value of expanded cut tobacco stem does not increased unlimitedly as steam flow rises prior to the drying process,but slowly increases to reach a certain extent before staying constant.
