About this write-up
This case study describes the engagement as recorded. The client is not named; figures and outcomes are as reported by the client and have not been independently audited.
The challenge
The brewery's brewhouse and packaging lines lost 28 hours weekly to conservative fixed-timer Clean-In-Place (CIP) wash routines. Standard SOPs ran 90-minute cleaning cycles on every fermentation tank regardless of soil levels, consuming excessive hot water, caustic soda, and boiler steam.
Objectives
- Connect CIP skid PLC historians and return line conductivity/turbidity sensors.
- Dynamically validate hygiene milestones (temperature, caustic concentration, turbidity clearance).
- Conclude wash rinse steps the exact second hygiene standards are met to recover production uptime.
Discovery
Sanitation sensor analysis showed that return rinse water reached zero chemical conductivity and clear turbidity 20–25 minutes before fixed SOP timers expired, indicating massive opportunity for dynamic cycle shortening.
What was built
- CIP Skid Return Conductivity & Turbidity Data Bridges. Streams return line conductivity, pH, flow, and optical turbidity tags in real time.
- Thermal Lethality (Fo) & Kinetic Soil Clearance Models. Algorithmic validation verifying microbiological hygiene criteria dynamically.
- Siemens SIMATIC & GEA CIP Controller Integration. Sends dynamic rinse completion triggers directly to automated CIP circuit valves.
- Automated SQF & 3-A Sanitation Compliance Dashboard. Logs timestamped sensor logs and audit records for digital quality assurance.
Outcomes as reported
Reported summary: +24h Weekly Line Uptime & -19% Wash Chemicals.
| Figure | What it refers to |
|---|---|
| +24h Line Uptime | Weekly production line uptime recovered across brewhouse and cellaring vessels |
| -19% Wash Chemicals | Caustic soda and sanitation rinse water saved through precision endpoint triggers |
| 100% Hygiene Score | Zero microbiological swab failures across 12 months of continuous brewing |
| -14% Steam Energy | Boiler thermal energy saved by eliminating redundant tank heating cycles |
Figures as reported in the engagement record; not independently audited.
Lessons
- Dynamic step conclusion based on optical turbidity and conductivity achieves higher microbiological consistency than arbitrary timers.
- Clear compliance dashboards showing automated 3-A sanitary logs satisfy external FDA and SQF quality auditors immediately.
Next steps
Integrating fermentation exothermic heat curves to optimize glycol chiller refrigeration cycles.
Implementation questions
Sanitation cycles only conclude when return conductivity confirms zero chemical residue and optical turbidity matches clear water benchmarks.
We support GEA, Tetra Pak, SPX Flow, Krones, and custom Siemens/Rockwell CIP skids.
No. The system connects to existing return-line conductivity transmitters, RTD temperature probes, and turbidity meters.
