When embarking on process optimisation, Miraka called on the specialist process control capabilities of Rockwell Automation. Leveraging Rockwell Automation’s Pavilion8® model predictive control (MPC) software platform and their decades of experience in delivering solutions in the dairy industry, Miraka teamed closely with Rockwell Automation engineers to specify and deploy a system to optimise their milk powder production plant.
“There was a high level of engagement from all the key stakeholders which facilitated a fast paced and successful implementation,” said Lynn Medich, Pavilion regional technical manager, Rockwell Automation.
“Leveraging our expertise in deploying model predictive control solutions in dairy standardisation, evaporation and spray drying we worked closely with Miraka to engineer a solution that generates operational improvements and business value.”
Model Predictive Control
All manufacturing processes have variability that can be caused by many factors. The primary objective of the Rockwell Automation Model Predictive Control (MPC) solution is to enhance stability in the process unit through the reduction of variability of key process parameters and optimal control to desired targets.
The Rockwell Automation Pavillion8 system includes modules to control, analyse, monitor, visualise and integrate information and processes. This system encompasses and manages dynamics and changing disturbances that occur minute by minute.
This delivers enhanced process stability so that defined control objectives can be achieved. In the case of powdered milk production, reducing the variability of key process parameters enables plants to drive to their processing and specification limits optimising yield and capacity.
Optimising Milk Powder Production in a Holistic Approach
The Miraka Pavilion8 solution was implemented in phases to effectively introduce model predictive control technology to operators while delivering value. Real time key performance indicators were deployed quantifying the value being delivered as each unit was commissioned.
