1. Food-Grade Materials
The tank is typically constructed from 304 or 316L stainless steel, with an interior surface highly polished to a roughness average (Ra) of ≤ 0.4 μm, meeting China's national standard GB 4806.9 for food-contact metal materials and products.
Non-toxic, corrosion-resistant, and easy to clean—minimizing milk residue and bacterial growth.
2. Insulation and Refrigeration
The tank features a polyurethane foam insulation layer (typically 50–80 mm thick) between its walls for effective thermal protection.
Most models are equipped with an onboard refrigeration unit capable of maintaining internal temperatures between 0°C and 4°C, suppressing microbial growth and preserving milk quality.
High-end models may support real-time temperature monitoring with remote data transmission.
3. Hygienic Design
Fully enclosed structure prevents contamination from dust, rain, insects, etc.
Integrated CIP (Clean-in-Place) system enables automated cleaning cycles—including acid wash, alkaline wash, and rinse—to ensure thorough sanitation.
All components (manholes, discharge outlets, breather valves, etc.) use sanitary quick-connect fittings compliant with food hygiene standards.
4. Multi-Compartment Option (Optional)
To accommodate milk from different farms or sources without cross-contamination, some models feature 2 to 4 independent compartments within the tank.
5. Safety and Compliance
Complies with China's "Administrative Measures for Raw Milk Production and Acquisition" and dairy product traceability requirements.
Equipped with GPS tracking, driving recorders, and electronic seals to enable full journey traceability and secure cargo integrity.
This specialized vehicle plays a critical role in the dairy supply chain, ensuring that raw milk maintains its freshness, safety, and nutritional value from farm to factory.
