Insulated Milk / Food-Grade Tank Semi-Trailer
The Insulated Milk / Food-Grade Tank Semi-Trailer is a specialized sanitary transport trailer engineered specifically for the safe, hygienic, and temperature-controlled hauling of fresh milk, liquid dairy products, fruit juices, edible oils, and other liquid foodstuffs. Built with high-grade food-grade austenitic stainless steel (AISI 304 or AISI 316L) featuring a mirror-polished interior (Ra ≤ 0.4μm), an ultra-thick high-density polyurethane foam thermal insulation layer, and a protective mirror-finish stainless steel outer cladding, it ensures strict hygienic compliance and minimizes temperature fluctuation (less than 1°C rise per 24 hours). Equipped with automated Clean-in-Place (CIP) rotating spray balls, sanitary butterfly valves, specialized manholes, and multi-compartment configurations, it guarantees absolute food safety and zero bacterial contamination. Paired with 3 commercial axles, adjustable air suspension, and dual-line WABCO ABS/EBS pneumatic braking, it delivers superior highway stability, thermal retention efficiency, and sanitary performance. Fully certified under FDA, 3-A sanitary standards, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Sanitary Stainless Steel Finish & Zero-Contamination Design
- Pristine Internal Hygiene: Fabricated from certified food-grade stainless steel (AISI 304/316L) with mechanically mirror-polished and electropolished interior surfaces achieving an ultra-smooth finish (Ra ≤ 0.4μm) to prevent bacterial growth and milk residue retention.
- CIP Cleaning Integration: Each compartment is equipped with high-efficiency Clean-in-Place (CIP) rotating spray balls, enabling automated, thorough internal washing and sanitization between transports.
- Sanitary Valve & Pipe Assembly: All discharge lines, fittings, and sanitary butterfly valves utilize food-safe Tri-Clamp connections and non-toxic seals to maintain absolute purity during loading and unloading.
2. High-Efficiency Polyurethane Insulation & Thermal Control
- Advanced PU Foam Layer: Encased in an 80mm–100mm high-density polyurethane foam insulation core that restricts heat transfer, ensuring temperature variation remains under 1°C over a 24-hour journey.
- Mirror-Finish Outer Cladding: Protected by a polished stainless steel outer shell that reflects solar radiation and resists environmental weathering and corrosion.
- Internal Anti-Surge Baffling: Fitted with dished sanitary baffles featuring smooth radii to dampen liquid sloshing during transport without creating hard-to-clean corners.
3. Structural Chassis Integration & Air Ride Smoothness
- Precision Air Ride Suspension: Paired with adjustable air suspension to absorb high-frequency road vibrations, protecting delicate liquid food emulsions (such as fresh milk) from agitation and separation.
- Robust Q345B Backbone Frame: The cylindrical insulated tank is securely mounted to a high-yield structural steel sub-frame protected by stainless shielding, delivering high torsional stiffness and load stability.
- WABCO ABS/EBS Pneumatic Braking: Dual-line air braking system incorporating WABCO ABS and emergency relay valves, ensuring smooth, synchronized stopping power under full liquid cargo loads.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the stainless steel tank shell and insulation structure; 1-Year warranty for axles, valves, and running gear.
- Delivery Lead Time: 30 – 35 working days upon order confirmation and engineering drawing approval.
