AIXBOILER, a leading A-GRADE boiler and pressure vessel manufacturer in China with over 45 years of expertise since 1978, offers state-of-the-art sterilization tank equipment (also known as retorts or autoclaves). These specialized pressure vessels are designed for thermal sterilization processes, effectively eliminating microorganisms through high-temperature steam, water spray, or immersion methods while preserving product quality and extending shelf life.
Produced in our advanced facility in Taikang Industrial Park, Zhoukou City, Henan Province, AIXBOILER sterilization tanks are ideal for the food and beverage industry (canned goods, pouches, bottles), pharmaceuticals (medical devices, solutions), and other sectors requiring aseptic processing. Our equipment supports batch sterilization with precise control over temperature, pressure, and cycle time to achieve commercial sterility (F0 value compliance).
Committed to sustainability, these tanks feature energy-efficient heat recovery systems, water recycling options, and robust construction for minimal environmental impact.
Key Features and Benefits
- Uniform Heat Distribution — Ensures consistent sterilization without overcooking.
- Automated Control Systems — PLC-based for precise cycle management and data logging.
- Versatile Processing Modes — Steam, water spray, immersion, or rotary for different packaging.
- High Safety Standards — Multiple safety valves, interlocks, and pressure monitoring.
- Easy Maintenance — Quick-opening doors and sanitary design for CIP cleaning.

Design and Construction Standards
AIXBOILER sterilization tanks are built to rigorous standards:
- Primary Standards: GB150/151 (China Pressure Vessel Code), ASME Section VIII (optional), PED 2014/68/EU, FDA-compliant for food contact
- Welding & Inspection: Automated TIG welding with 100% NDT (RT, PT, UT)
- Surface Finish: Internal polishing Ra ≤ 0.4 μm for hygienic applications
- Heat Transfer: Indirect steam via jackets or direct injection with air overpressure
CFD analysis optimizes flow patterns for uniform temperature distribution.
