Method for Decreasing Difference of Moisture Content in Output Strips from Strip Casing System Between Batches

In order to reduce the difference of moisture content in output strips from the strip casing machine between batches,the casing machine was improved.To reduce the temperature fluctuation of and the casing droplets in circulated hot air,the inserted exhaust screen was replaced by a screen belt supported by side chains,a self-cleaning device for the screen belt was installed,and a set of casing droplets collecting and cleaning device was added.The results showed that the difference between moisture contents in cased strips of different batches,the extreme difference between batches decreased from 1.47 to 0.46 and was mostly controlled within ±0.5;the extreme difference of input cut tobacco to thin plate dryer between batches reduced from 1.98 to 0.58 and was mostly controlled within ±0.6.The intrinsic quality of cigarette was promoted.
