Abstract

The inflow line to the drying cylinder is provided with a quantity measuring means to determine the amount of steam being delivered to the cylinder as well as a pressure-regulating means for controlling the pressure prevailing in the cylinder. A signal emitter receives a measurement signal from the quantity-measuring means and transmits a control signal to the pressure-regulating means to bring about an adjustment in the pressure. Use is also made of a bypass line and a thermocompressor to draw steam from the condensate-separator to maintain a constant flow of steam in the drying cylinder.
