Plant Floor Walk-Through
Six stages. Every failure mode. One audit.
Scroll through each processing stage. Left panel shows what we find. Right panel shows what we deliver. The ratio of red to green shifts as you walk the line.
01 / 06Milk Reception
Stage 01Current State
What we find in aging reception circuits
Common failure points at the silo and intake manifold
- ✗Silo temperature fluctuating ±2°C above 4°C threshold
- ✗No automated CCP logging — manual paper records only
- ✗Inlet valve seals last replaced >18 months ago
- ✗Somatic cell count monitoring: weekly batch only
- ✗FDA 21 CFR 131.110 temperature records: non-compliant
2.1°CAvg. temp deviation in unmonitored silos

✓ All points resolvedAudit documentation included
Stage 02Current State
The 6% yield loss nobody can explain
Where your margin disappears at the separator bowl
- ✗Separator bowl running at factory default — never recalibrated
- ✗Fat standardization ±0.4% above target: product giveaway
- ✗Discharge interval set to 30 min — sludge buildup reducing efficiency
- ✗No inline fat measurement — lab checks every 2 hours
- ✗Bearing vibration above 4.5 mm/s RMS: failure within 90 days
+6.2%Yield recovered after separator recalibration
03 / 06HTST Pasteurization
Stage 03Current State
Thermal audit flags your HTST is not hitting spec
Common deviations that trigger regulatory action
- ✗FDD (flow diversion device) last tested 14 months ago — EU limit 6 months
- ✗Plate heat exchanger: 3 plates fouled, reducing LMTD by 18%
- ✗Holding tube thermocouple calibration expired — log invalid
- ✗No continuous phosphatase test since last audit — compliance gap
- ✗Regeneration section efficiency at 67% — energy waste of €18k/yr
14moAvg. gap since last FDD certification at audited plants
HTST PasteurizationEngineered Solution
HTST requalified: 72°C / 15s with full FDD documentation
Flow diversion valve testing, plate inspection, and thermal validation
- ✓FDD tested and certified on 6-month schedule with signed documentation
- ✓Plate inspection and regasketing: LMTD restored, +12% energy efficiency
- ✓Thermocouple calibration traceable to NIST/NPL standards
- ✓Continuous alkaline phosphatase monitoring: real-time compliance signal
- ✓Regeneration efficiency at 95%: €18k/yr energy saving locked in
✓ All points resolvedAudit documentation included
04 / 06Homogenization
HomogenizationEngineered Solution
Stabilized at 200 bar: shelf-life validated, label compliant
Valve seat inspection, pressure profiling, and product texture testing
- ✓Pressure profiled and stabilized at 200 ± 5 bar — fat globule D(v,0.9) < 1 µm
- ✓Valve seat inspection on 500-hour schedule: wear tracked and trended
- ✓Cream-line test passed at 28 days: UHT shelf-life claim fully supported
- ✓Pressure data logged to batch record — shelf-life documentation complete
- ✓Piston seal replacement: 80 L/hr loss eliminated, €28k/yr recovered
✓ All points resolvedAudit documentation included
Stage 04Current State
Pressure inconsistency is destroying shelf-life claims
What fluctuating homogenizer pressure does to your product
- ✗First-stage pressure varying ±25 bar — fat globule size inconsistent
- ✗Homogenizer valve seats last inspected >12 months ago
- ✗Cream-line forming in UHT product within 3 days: customer complaint risk
- ✗No pressure recording in batch record — shelf-life claim unsupported
- ✗Pump piston seals leaking: 80 L/hr product loss unaccounted
±25 barTypical pressure deviation in unchecked homogenizers
05 / 06Aseptic Filling
Stage 05Current State
Filling line contamination events are a recall waiting to happen
Sterility failures at the filler that never make it to the audit report
- ✗H₂O₂ sterilization concentration not validated since commissioning
- ✗Sterile air overpressure in filling zone dropping below 10 Pa
- ✗Environmental monitoring: 2 positive Listeria swabs in last 6 months
- ✓Carton seam integrity: visual check only — no leak test protocol
- ✗Filler CIP cycle not validated for biofilm removal in dead legs
100%Carton integrity when automated seam testing installed
Aseptic FillingEngineered Solution
Validated aseptic zone: zero positive environmental tests in 12 months
H₂O₂ concentration profiling, sterile air validation, and environmental monitoring
- ✓H₂O₂ concentration profiled at 35% ± 1% — validated and documented
- ✓Sterile air system rebalanced: 25 Pa maintained across all filling heads
- ✓Environmental monitoring program: 0 positive results for 12 consecutive months
- ✓Automated seam tester: 100% carton integrity check, reject rate <0.1%
- ✓Dead-leg CIP validation: biofilm elimination confirmed by ATP bioluminescence
✓ All points resolvedAudit documentation included
06 / 06CIP Circuits
CIP CircuitsEngineered Solution
CIP validated, documented, and audit-ready in 30 days

Stage 06Current State
Your CIP is the last item checked and the first thing that fails audit
Documentation gaps and chemical concentration drift that inspectors find immediately
- ✗NaOH concentration drifting ±0.3% from target — biofilm risk
- ✗CIP circuit map last updated when plant was commissioned in 2014
- ✗No conductivity monitoring on return leg — cleaning efficacy unverified
- ✗CIP log: paper-based, illegible, 3 months missing from records
- ✗Spray ball coverage in 400 L buffer tank never validated
