Apr 01, 2000 This paper describes the modelling and the PID control of a drying process. The plant uses a co-current rotary dryer to evaporate moisture of a waste product generated by olive-oil mills, called alpeorujo or two phase cake.The paper shows the development of a model based upon first principles combined with experimental results. Yliniemi, Leena, Advanced control of a rotary dryer Department of Process Engineering, University of Oulu, FIN-90570 Oulu 1999 Oulu, Finland (Manuscript received 31 May, 1999) Abstract Drying, especially rotary drying, is without doubt one of the oldest and most common unit operations in the process industries.

Transactions of the Institute of Chemical Engineers 40, I83 Tihua, W. (1986) Modelling and design of an adaptive control system for a rotary dryer. *** Head, Control Engineering Laboratory, University of Oulu Abstract: The control of the drying process in a rotary dryer is difficult due to delay time and the very complex process that includes the movement of the solids in addition to thermal drying. Thus, even today rotary dryers are partly manually Nov 12, 2014 The selection and design of dryers with an appropriate process control system can maximize product quality, throughput, and dryer safety, and can minimize production cost and environmental pollution.
