    • A humidifying cylinder (21) includes a first rotatable cylinder (23) having an inlet end (25) and an outlet end (27) and plurality of first blades (29) extending substantially radially outwardly from an exterior surface (31) of the first cylinder (23). The humidifying cylinder (21) further includes a second rotatable cylinder (33) having an inlet end (35) and an outlet end (37) and a plurality of second blades (39) extending substantially radially inwardly from an interior surface (41) of the second cylinder (33), the second cylinder (33) being substantially coaxial with the first cylinder (23) and the first cylinder (23) being disposed inside of the second cylinder (33) such that the exterior surface (31) of the first cylinder (23) and the interior surface (41) of the second cylinder (33) define an annular space (43). At least one drive (45) is provided for rotating the first cylinder (23) and the second cylinder (33). At least one conduit (47) is disposed in the annular space (43) for introducing moisture into the annular space (43). A method of humidifying material is also disclosed.

    • A moisture conditioning method is provided in which tobacco material and steam are supplied to the interior of a rotor to condition the moisture of the tobacco material while the tobacco material passes through the rotor. In the conditioning method, a deviation between the temperature of the tobacco material at the outlet of the rotor and a target temperature is obtained, and cascade control is performed on the supply flow rate of the steam supplied to the rotor so as to eliminate the deviation. The cascade control includes a main control process having a plurality of control areas for controlling the supply flow rate based on a reference flow rate in the individual control areas, and a sub-control process executed in parallel with the main control process for changing the reference flow rate in accordance with an average value of the deviations within a fixed period.
    • 提供了一种湿度调节方法,其中烟草材料和蒸汽被供应到转子内部以调节烟草材料的湿度,同时烟草材料通过转子。 在调节方法中,获得转子出口处的烟草材料的温度与目标温度之间的偏差,并且对供给到转子的蒸汽的供给流量进行级联控制,以消除偏差 。 级联控制包括主控制过程,其具有多个控制区域,用于基于各个控制区域中的参考流量来控制供给流量,以及与用于改变参考的主控制处理并行执行的子控制处理 流量根据固定时间内的偏差的平均值。
