CIP Comparison¶
FUERST WIACEK Side-by-side comparison of all CIPs in the brewery
This page is a comparison/scheduling tool — it does not replace the actual SOPs. Decision values (concentrations, conductivity targets, ATP thresholds, soak times) live inline in each CIP SOP where the operator can see them at the moment they need them. Use this page to plan the week, train someone, or check that you're not running parallel CIPs that will starve hot water or chemical supply.
Comparison Table¶
| CIP | Frequency | Method | Up-con | Conductivity | SOP |
|---|---|---|---|---|---|
| Wortway CIP | Per brew + end-of-week | Botec auto: caustic → acid → PAA (sani only) | Tank 1 | < 0.15 mS | SOP |
| Wortway Sani | Each brew, at boil start | Botec auto: PAA | — | — | SOP |
| Brewhouse CIP | Weekly + post-dark-malt | Botec auto: caustic → acid | Tank 1 | < 0.15 mS | SOP |
| HLT CIP | Annual | Manual: acid only (descale), 30 min + soak | — | < 0.15 mS | SOP |
| Fermentation Tank CIP | After every tank emptying | Manual mobile pump: pre-caustic → main caustic → acid → PAA, 20 min each | Dosing tank | < 0.15 mS, ATP < 20 RLU | SOP |
| Cellar Piping CIP | Before tank-to-tank transfers; ad-hoc | Botec auto (CIP Piping Cellar), ~90 min |
Tank 2 | < 0.15 mS | Botec 003 → CIP (no SOP yet) |
| Yeast Brink CIP | Before every harvest | Manual: caustic → acid → PAA, 20 min each | Dosing tank | < 0.15 mS | SOP |
| Kegger Line CIP | Before every KeyKeg run | Manual: caustic → acid → PAA, 20 min each | Dosing tank | < 0.15 mS | SOP |
| Canning Line CIP | Start of packaging week + before every filling run | Botec auto: caustic → acid → PAA (sani before filling) | Tank 2 | < 0.15 mS | SOP |
| Canning Foam-down | After each daily run | Manual foamer (surface clean) | — | — | SOP |
Note
Quick-reference only. The CIP SOP itself is authoritative — chemical doses, recirculation pressures, vent valve handling, panel rebuild steps, and edge cases all live there.
Up-Concentration Tank Map¶
| Up-con tank | Supplies | Triggered by these CIPs |
|---|---|---|
| CIP Tank 1 | Brewhouse + Wortway | Brewhouse CIP, Wortway CIP |
| CIP Tank 2 | Canning + cellar lines | Canning Line CIP, Cellar Piping CIP |
Up-concentration must complete before the CIP that needs it. Same-day is required, not back-to-back. See CIP Up-Concentration SOP.
Mid-CIP Stop Priority (Tank CIP only)¶
If a Tank CIP cannot be completed in one session, the safe stopping points in order of preference:
| Priority | Stop point | Restart with |
|---|---|---|
| 🟢 Best | After Acid + Rinse | Short rinse → PAA → use |
| 🟡 Acceptable | After Main Caustic + Rinse | Acid → Rinse → PAA |
| 🟡 Conditional | After Acid (acid still in tank) | Drain → Rinse → PAA. Don't repeat — degrades gaskets. |
| 🔴 Not recommended | After Caustic (caustic still in tank) | Caustic damages seals — use only in emergency. |
| 🟡 After PAA | Use within 24 h of PAA | If > 24 h: full re-CIP without pre-caustic. |

Conflicts to Avoid¶
| Don't run in parallel | Why |
|---|---|
| Up-con + Mash-in | Hot water demand drops mash-in flow → temperature error or brew abort |
| HLT CIP + Brew | HLT is offline during the clean — can't supply mash water |
| Two simultaneous CIPs on the same up-con tank | Second CIP will run with depleted caustic |
| Wortway CIP + Wortway Sanitisation on the same brew | Sanitisation must follow CIP, not run alongside |
