Abstract

Making wood fibers from wood chips by feeding the chips through a tamping screw into a boiler, where they are exposed to high pressure and temperature, and discharging the chips under rapid expansion so that they separate into fibers, comprises measuring the conductivity of a plug of chips leaving the screw and using the result as a control parameter for controlling downstream processing of the chips and/or fibers. An independent claim is also included for apparatus for making wood fibers from wood chips, comprising a tamping screw (1) for feeding the wood chips into a boiler, where they are exposed to high pressure and temperature, and a discharge device for discharging the chips under rapid expansion so that they separate into fibers, comprises a sensor (11) for measuring the conductivity of a plug of chips leaving the screw.
