Improvement of Flow Control at Initial Stage of Tobacco Feeding for HXD

The tobacco entering HXD pneumatic cut tobacco drier increases gradually at the initial stage of tobacco feeding,the unsteady tobacco flow results in over-dried or under-dried cut tobacco,therefore,the running of front belt conveyor is modified.When DCC cylinder starts up,the thickness of tobacco carpet on the belt is kept at a normal level by lowering the speed of subsequent belt conveyer until the conveyer reaches its normal speed.After improving,the dried cut tobacco approaches to targeted moisture content quickly,the over-dried or under-dried cut tobacco is avoided,the consumption of cut tobacco decreases,and the stability of tobacco flow in HXD is improved.
