Abstract

Method of cooling and moisturising tree fibres comprises conveying the fibres through a treatment chamber (1) with the aid of transport air, wherein finely-distributed drops of cooling and moisturising liq. are sprayed to evaporatively cool the transport air and fibres, as well as to moisturise the fibres, and then sepg. the cool, moist fibres from the transport air and obtd. vapour. (Reissued of the entry advised in week 9420 based on complete specification)
