Application of an Automated Cascade Temperature Control System in a Fluidized Bed Spray Dryer
Year: 2025
Type: article
Abstract: This article analyzes the temperature control in the fluidized bed of a drying plant, using a cascade automatic controlsystem, studied in ideal and production conditions. The system provides high quality control indicators while maintaining goodstability and meeting the set technological requirements. For automatic control of the fluidized bed dryer, a DeltaV - Emersondigital automatic process control system was used. The control object was approximated to a model, with the help of whichnumerous simulations were implemented in order to select the most effective structure and parameters of the control regulators.The adjustment of the automatic control system in production conditions improves the quality of control, allowing to track,analyze and compensate for disturbing effects. The commented system has been implemented in real operating conditions,works well and provides an opportunity to optimize the drying process, in search of the best technical and economic indicatorsof the specific production.
