Scenario summary
You operate a hub-airport airline catering center: 40,000–150,000 meals/day, 600–2,000 IATA standard catering trolleys recycled per day. Trolleys are full-size ATLAS or KSSU, returning from intercontinental, regional and short-haul flights with mixed soil profiles.
The cleaning challenge
IATA / IFSA sanitization standards require documented 82°C thermal exposure on every trolley. Throughput must keep pace with arrival batches (200+ trolleys/hour at hub peak). Per-trolley traceability is required for airline customer reporting.
Recommended PTW-1900 setup
Configuration: 2–4 PTW-1900 machines in parallel lanes, shared booster water tank.
Chamber: Custom 900 × 1100 × 2000 mm to accommodate full-size ATLAS trolley footprint.
Heating: Electric 70 kW per machine, supplemented by shared 200 kW booster bank for sustained throughput.
PLC profiles:
- Standard 6-min — daily trolley sanitization
- Heavy 8-min — heavy protein meal trolleys (intercontinental long-haul)
- Dietary Reset 8-min — sanitization-only between Halal/Kosher/vegan/Hindu meal cohorts
Critical accessories: Barcode reader (trolley ID scan before load), MES integration via OPC-UA, dual chemical dispensing, steam-exhaust heat recovery for centers in residential proximity.
Throughput: 70 trolleys/hour per machine × 3-machine parallel install = 210 trolleys/hour sustained.
Expected ROI
- Labour savings: replaces 8 wash workers across two shifts → ~$340,000 annual
- Net annual savings: ~$310,000
- 3-machine install cost: ~$140,000 FOB + freight
- Payback: ~5–6 months
Airline catering FAQ
Q: Per-trolley traceability for airline customer reporting? A: Barcode reader scans trolley ID before load. PLC links cycle data to trolley ID. Export per-airline cycle reports as CSV monthly.
Q: How is steam exhaust handled for centers near residential areas? A: Optional steam-condensation heat exchanger captures exhaust before discharge. Reduces visible plume and recovers ~10% energy.
Q: We need IFSA documentation for our airline audits. Does the PTW-1900 produce it? A: Yes. CSV cycle log + machine specification + chemical dose log + operator audit log together constitute IFSA documentation.
