Advanced Control of a Rotary Dryer ScienceDirect
Sep 01, 1998 Two kinds of intelligent, hybrid control systems for a rotary dryer are presented. The main controlled variable is the output moisture of solids and the main manipulated variable is the input temperature of drying air which correlates to the fuel flow. The main disturbances of the process are the input moisture of solids and the feed flow.

Advanced control of a rotary dryer University of Oulu
The control of a rotary dryer is difficult due to the long time delay, which means that accidental variations in the input variables can disturb the process for long periods of time before they are reflected in the output variables. To eliminate such disturbances at an early stage, increasing interest has been shown in more sophisticated control systems such as model-based
Best practices manualdryers SlideShare
Mar 03, 2016 The above control systems manual and automatic do not effectively tackle the disturbances at the input. For example, a 1 Tph dryer suddenly operates at 50 of the load and if the inlet moisture content is higher, in the above control systems, though work hard to give desired moisture content, the energy consumption is not optimised.
