The process of always producing sugar crystals of a defined size in large volumes requires a robust process control strategy. With sustainability a key focus of most sugar producers, the challenges are to maintain consistency (reduce wastage, rework) and reduce dependence on human interaction as staffing levels in all operations are already stretched. Siemens is working with sugar manufacturers both in Australia and around the world to help with process control strategies whether in continuous vertical or horizontal pans, or in vacuum batch pans. This presentation aims to show through case studies and reference examples how Siemens has helped by implementing process control technologies to maximise the consistency of the crystallization process whilst at the same time delivering benefits around energy efficiency and overall plant reliability. We address topics including: crystallization with NAHMAT PCS7 Pan Control solution; Digitalisation tools; Energy efficiency monitoring with IoT Suite and drive application technology. Key words Digital transformation, crystallization, energy efficiency
