Project Introduction

Shantou Fengle Foods, a Guangdong-based manufacturer of vacuum-packed seafood and ready-to-eat meals, faced mounting recalls in 2023 due to inconsistent steam sterilization from its aging oil-fired boilers. During peak shifts, steam pressure drops below 0.8MPa caused batch sterilization temperatures to fluctuate between 118°C and 126°C – breaching China’s GB 29923-2013 food safety standard. With Guangdong’s 2024 mandate requiring ≤15 mg/m³ particulate emissions and seafood processing lines demanding 121°C±1°C steam for 30-minute cycles, the company deployed the ​​WNS2-1.25-Q θ6 gas steam boiler​​ to synchronize with HACCP-critical thermal processes.

Product Advantages

The θ6-series boiler’s rapid-response combustion system achieves ​​95.2% thermal efficiency​​ – 22% higher than legacy units – through helical corrugated furnace tubes that accelerate heat transfer to 2t/h steam output. Its three-stage steam purification system (mechanical separation + centrifugal drying + microporous filtration) ensures 99.95% dryness for eliminating bacterial biofilm risks in retort chambers. Customized for food-grade operations, the boiler’s 316Ti stainless steel construction resists chloride corrosion from seafood blanching vapors, while integrated CIP spray balls enable automated weekly cleaning cycles compliant with SSOP protocols. Real-time steam quality tracking via FDA 21 CFR Part 11-compliant software reduced sterilization deviations by 89% during audits.
