Document Type and Number:

WIPO Patent Application WO/2013/136487

Kind Code:

A1

Abstract:

Provided is a humidification method which comprises supplying a starting tobacco material and steam into a rotor and humidifying the starting tobacco material during the passage of the starting tobacco material through the rotor. The humidification method involves: a main control step for determining a deviation between the outlet material temperature of the starting tobacco material at the outlet of the rotor and a target temperature and then cascade-controlling the flow rate of the steam to be supplied into the rotor so as to eliminate the deviation, wherein multiple control areas exist in the cascade-control and the supply flow rate is controlled on the basis of a standard flow rate in each of the control areas; and a side control step, said side control step being performed in parallel to the main control step, for changing the standard flow rate on the basis of the average deviation during a definite period.
