Preferably, the cross section of said vertical drying tube is square.
Preferably, the top of said cyclone separator is communicated with said flow type calorifier through a backwind tube.
Preferably, said backwind tube connects an air exhauster near a side of flow type calorifier, and the air outlet of said air exhauster connects a humidity discharging pipe.
Preferably, said flow type calorifier is a combustion furnace.
Preferably, the spray vapour gas direction of said steam jet is vertical with the blanking direction of feed pipe.
Preferably, said steam jet is between said feed pipe and said flow type calorifier.
Preferably, said feed pipe is provided with the charging gas lock.The charging gas lock is set, makes barrel air-flow and outer gas stream isolated, keep internal heat stable, be more conducive to the pipe tobacco charging simultaneously.
Preferably, said discharge nozzle is provided with the discharging gas lock.The discharging gas lock is set, makes barrel air-flow and outer gas stream isolated, keep internal heat stable, be more conducive to the pipe tobacco discharging simultaneously.
Pneumatic drying device of the present invention through at feed pipe steam jet being set, carries out warming and humidifying to pipe tobacco; Through the distance between feed pipe and the dry tedge is provided with; Make pipe tobacco can be evenly dry,, avoid conglomeration occurring at the arc connecting portion after making pipe tobacco get into because of the injection of steam through the distance between steam jet and the dry tedge is provided with; Cause the pipe tobacco loss; And used drying tube only needs take bending setting at arc connecting portion place, therefore, practices thrift tubing.
