6-Point Wet Paste, 85 °C Hot-Fill, Vacuum Cap & CIP FAT Protocol

Verify ±0.2%–0.5% viscous weight repeatability, solid-to-oil uniformity, 35–55 kPa lug-cap vacuum, clean jar threads, and 15-minute sanitary CIP teardown.

Check Compatibility

Never Approve a Sauce Filler on Cold Water Alone!

Cold tap water hides cavitation on 45,000 cP BBQ paste, stringing on sweet chili glaze, solid settling in chili crisp, and seal expansion at 85 °C! Grounded in sauce line sizing and guides and hot-fill viscosity and sanitary specs, insist on a heated viscous + particulate Factory Acceptance Test using food-grade CMC/xanthan gel, vegetable oil + chili/bean solids, or actual batch sauce.

Verify all six checkpoints below before authorizing ocean freight.

Six-stage 85 °C hot-fill sauce jar line from pre-warm rinsing through rotary-valve piston filling, vacuum capping, cap inversion, and cooling
Tilting capped hot-fill bottles 90–180° for 20–30 seconds sterilizes cap headspaces using the sauce's own 85 °C thermal energy.

Six-Point Sanitary Sauce Line FAT Matrix

Quantitative acceptance tests executed prior to crating:

FAT Checkpoint Test Method Pass Criterion
1. Multi-Head Weight Cpk Weigh 10 consecutive cycles across all nozzles (500 g paste) Within ±0.2%–0.5% (±1.0–2.5 g); Cpk >= 1.33
2. Solid-to-Oil Ratio Drain & weigh solids from Jar #1, #100 & #300 (chili oil) Drained solid weight variance <= ±3% across batch
3. Thread & Neck Cleanliness Inspect 100 filled jars under UV/bright light before capper 0 sauce drops on exterior neck threads; clean drip tray
4. 85 °C Thermal & Seal Hold Circulate 85–90 °C heated media continuously for 60 min 0 PTFE piston/spool leaks; hopper holds ±1.5 °C
5. Vacuum Lug Integrity Cool 30 steam-capped glass jars to 30 °C; pierce w/ gauge 35–55 kPa internal vacuum; 100% dud-detector reject test
6. Timed Sanitary Strip/CIP Flush CIP manifold + strip 1 cylinder/rotary valve by hand Full tool-free strip & reassembly <= 15 minutes

Technical pairing matrix matching thin high-salt soy/vinegar, smooth emulsions, and >8 mm chunky sauces to pump physics and SUS316L steels
High-acid vinegar + salt sauces (pH 2.8–3.8, 3–15% NaCl) pit SUS304 welds rapidly—always specify SUS316L wetted manifolds.

Sanitary Sauce & Hot-Fill Notes

  • Verify SUS316L With Handheld XRF Analyzer: Confirm 2.0%–2.5% Molybdenum (Mo) content on hoppers, pistons, rotary spools, and diving nozzles during FAT—separating genuine SUS316L from SUS304 instantly.
  • Test Worst-Case Squeeze Bottle Stability: Empty top-heavy inverted PET squeeze bottles tip easily at conveyor transfers—run 200 empty + filled squeeze bottles at 115% line speed to verify guide rails and pucks.
  • Save Per-Nozzle Servo Calibration Offsets: Export touchscreen recipe backups recording dive stroke mm, bottom-up rise curve, suck-back delay, and agitator RPM.
