    Jun 01, 2000 The basic idea of the control scheme we propose is to fully exploit the fact that switching from standard mode to overdried-mode results in the change of the sign of the gain from input moisture content to output sugar temperature; in other words, when the dryer is working in over-drying conditions adding water at the dryer inlet results in a temperature decrease at the output, whereas when the dryer
