Case Studies

Real plants. Real results.

Every engagement is different — different plants, different problems, different solutions. What's consistent is the outcome: measurable improvement in plant performance. Here are some examples of what we've delivered.

Automation TuningDairy Processing

Pasteuriser throughput increased 18% through control loop optimisation

Challenge

A dairy processing facility was running their pasteuriser at 82% of design capacity. The plant had been commissioned 18 months prior and operators had accepted the conservative control settings as 'how the plant runs'.

Approach

SDA conducted a full control loop audit across the pasteuriser and associated CIP circuits. We identified 14 PID loops operating with excessive integral action causing oscillation, and three cascade loops that had never been properly tuned.

Outcome

Following retuning and control narrative revision, the pasteuriser achieved 97% of design throughput — an 18% improvement. Product quality variability also reduced by 40% as measured by out-of-spec batch rate.

CIP programme redesign reduced water consumption by 30% and cycle time by 25%

Challenge

A beverage manufacturer was experiencing excessive CIP cycle times that were limiting production availability. Water and chemical costs were also significantly above industry benchmarks.

Approach

SDA performed a detailed CIP programme review including conductivity profiling, temperature mapping, and flow velocity analysis across all circuits. We identified oversized pre-rinse volumes, incorrect chemical concentrations, and inefficient recovery sequencing.

Outcome

Redesigned CIP programmes reduced total cycle time by 25%, freeing up an additional 2 hours of production time per day. Water consumption dropped 30% and chemical costs reduced by 22%.

Centrifuge vibration resolved — eliminating unplanned shutdowns and restoring design capacity

Challenge

A food processing facility was experiencing recurring unplanned shutdowns on a critical centrifuge due to high vibration trips. The issue had persisted since commissioning and had been attributed to product variability by the OEM.

Approach

SDA conducted a vibration analysis and mechanical inspection that identified a combination of rotor imbalance and a resonant frequency in the support structure that coincided with the operating speed range. The OEM's diagnosis was incorrect.

Outcome

Following rotor rebalancing and a structural modification to detune the support frame, the centrifuge has operated without a vibration trip for 14 months. Design capacity has been fully restored.
