ABSTRACT:
A drying control system and method for obtaining a substantially uniformly dried low moisture content web efficiently with reduced energy usage in a papermaking process is provided. The drying rate of the web in this process is precisely controlled by detecting and monitoring the web or felt low and high cross-direction temperature profiles and then actuating drying rate modulators as required to increase or decrease the drying rate to produce a substantially flat temperature profile in response to temperature profile information provided to an automatically or manually controlled central control system by web high temperature and low temperature sensors.
