An instantiation of material moisture regain method is described below.

Expanded cut tobacco moisture regain method, comprises the following steps：

Moisture content scope [the first preset value, the second preset value] according to expanded cut tobacco after the moisture regain of technological requirement, it is determined that Expanded cut tobacco needs to improve moisture regain parameter of how many moisture content to set substep moisture regain each operation, it is preferable that humidification funnel 21 increases Plus expanded cut tobacco moisture content 0.8%~1.2%, get damp again the increase expanded cut tobacco of groove 22 moisture content 2%~4%, drum-type moisture regain of shaking Machine 3 increases expanded cut tobacco moisture content 2%~3%.

Moisture content scope [the first preset value, the second preset value], refers to that moisture content is more than or equal to the first preset value, and Moisture content is less than or equal to the second preset value.

Expanded cut tobacco humidification ratio according to technological requirement, calculates moisture regain and shakes the humidification requirements of groove 22, it is determined that opening moisture regain Shake the quantity of jet pipe 41 on groove 22：When needing humidification 0.8%~1.2%, first jet pipe 41 is opened, close second jet pipe 41st, on the 3rd jet pipe 41, the 4th jet pipe 41 manual modulation valve 7, it is necessary to be humidified 1.6%~2.4% when, open first Jet pipe 41 and the 3rd jet pipe 41, the manual modulation valve 7 closed on second jet pipe 41, the 4th jet pipe 41 is, it is necessary to be humidified When 2.4%~3.6%, first jet pipe, 41, second jet pipe 41 and the 3rd jet pipe 41 are opened, closed on the 4th jet pipe 41 Manual modulation valve 7,4 standard-sized sheets of the manual modulation valve of jet pipe 41 7 of remaining situation.
