OEE & Downtime in Food & Beverage Manufacturing
Key takeaways
- In F&B, the packaging and filling end usually sets the line's OEE, not the process side.
- The big three losses: changeovers, CIP/sanitation, and filler/capper micro-stops.
- Perishable WIP makes a stoppage more expensive than the lost minutes alone.
- Micro-stops are the most under-counted loss on filling and packaging lines.
Food & beverage is a perfect storm for hidden losses: high-speed lines, frequent changeovers, strict hygiene, perishable product, and thin margins on high volume. The result is that measured OEE often looks acceptable while real output, and real cost, tells a different story.
What's a good OEE in food & beverage?
One published study of 23 Swedish companies found the food and beverage group averaging 74% OEE, measured automatically in a system where most machines reported the default 100% for speed and quality (source: Hedman et al., 2016). The usual reference is 85% world-class (traced to Nakajima, Introduction to TPM, 1988), and published plant studies found average OEE of about 55% to 65% (sources: Ljungberg, 1998; Hedman et al., 2016); the more useful target is your own line's trend. The process side (mixing, brewing, cooking) can run high, but the packaging and filling end drags the line average down because many machines run in series: a stop anywhere starves or blocks everything downstream.

The biggest losses in F&B
| Loss | Why it's big in F&B | OEE factor |
|---|---|---|
| Changeovers | Format, flavour and allergen changeovers with mandatory cleaning between runs | Availability |
| CIP & sanitation | Clean-in-place cycles and washdowns are non-negotiable and eat scheduled time | Availability |
| Filler / capper / labeller micro-stops | Jams, misfeeds, foaming, mis-caps: short, frequent, rarely logged | Performance |
| Speed loss | Running below rated speed to control foaming, fill accuracy or product variation | Performance |
| Startup & giveaway | Scrap and over-fill (product giveaway) after every changeover and washdown | Quality |
The standout is the micro-stop. Filling and packaging lines generate dozens an hour, each cleared in seconds, none logged. That's the hidden factory, and in F&B it's often a large recoverable loss.
F&B filling/packaging lines are micro-stop heavy. See what yours is costing in units and euros.
One filler shift, worked through
Illustrative numbers for a bottling line, so you can check the math against your own shift. Planned production time is 450 minutes (an 8-hour shift minus a 30-minute break). The shift log records a 25-minute flavour changeover and a 40-minute CIP: 65 minutes of downtime. The filler is rated at 200 bottles a minute but runs at 180 to keep foaming down, and it stops about 90 times for 20 seconds each, which nobody logs.
| Step | Calculation | Result |
|---|---|---|
| Availability | run time 385 min (450 - 65) / 450 | 85.6% |
| Bottles made | 355 running min (385 - 30 of micro-stops) x 180 a minute | 63,900 |
| Performance | 63,900 x 0.005 min / 385 | 83.0% |
| Quality | 62,700 good of 63,900 (1,200 underfills and startup rejects) | 98.1% |
| OEE | 85.6% x 83.0% x 98.1% | 69.7% |
The log explains 65 lost minutes. The line lost 136.5: 65 of changeover and CIP, 30 of micro-stops, 35.5 of running below rated speed and 6 of rejects. More than half of the loss never reached the log, and none of it looks like a breakdown. That is how an F&B line can look fine on paper and still miss its volume.
Reason codes for a filling and packaging line
A short list everyone uses beats a long one nobody does. A starting set:
- Changeover: format, flavour, allergen (keep allergen separate, it carries its own cleaning time)
- Cleaning: CIP, washdown, unplanned clean after a spill
- Filler: bottle jam, foaming, fill weight out of tolerance
- Capper and labeller: misfeed, mis-cap, label jam
- Starved or blocked: no bottles from the depalletizer, case packer or palletizer backed up
- Quality hold: QA check, seal or date code issue
Log them in the free OEE tracker and the downtime Pareto ranks them for you; the downtime log template does the same on paper.
What a camera shows on a filling line
A stop code tells you the filler stopped, not why the bottle tipped over in the seconds before. Where cameras are fitted, Fabrico's camera-based OEE software syncs camera video with machine data, so you can replay the moment the line stopped. Cameras also catch short stops and a line that is switched on but not producing, the losses nobody writes down: in the shift above, that is the 30 minutes the log never saw.
What downtime costs in F&B
Two things make a stopped F&B line costlier than the math first suggests: perishable WIP (product in the line may be scrapped on a long stop) and thin margins on high volume (you make the money on throughput, so lost throughput hurts disproportionately). Add idle labour and restart giveaway and the per-hour figure climbs fast. Estimate your downtime cost →
How leading F&B plants cut the losses
- Measure automatically from the line, not from operator logs: the micro-stops never make the logs.
- Get the true cause of each short stop (which machine, what condition) so fixes target the real failure mode.
- Attack changeover time with SMED, and treat CIP scheduling as a planning lever.
This is where Fabrico fits F&B specifically: it reads OEE straight from the line and shows camera video of stops (where cameras are fitted) with a suggested cause, automatically. For EU food producers, it's also EU-built, with data hosted in the AWS EU region.
What OEE should a food & beverage line target?
Start by beating your own trend: attack micro-stops and changeovers before chasing big breakdowns. 85% is the world-class north star (traced to Nakajima, Introduction to TPM, 1988).
Why are micro-stops so bad in food & beverage?
High-speed serial lines amplify them: every short stop on one machine starves or blocks its neighbours. And product factors (foaming, sticky labels, variable natural product) cause stops that don't happen in other industries.
Does this apply to beverage and brewing too?
Yes, the filling/packaging hall is where most beverage OEE is lost, for the same micro-stop and changeover reasons.
