Great cold chain project in the Southwest region: Ca Mau is the shrimp capital of the country with an export turnover of billions of dollars. The 10,000 ton cold storage complex project in Dam Doi is a key project to help improve processing capacity, storage and stabilize raw shrimp prices for thousands of high-tech shrimp farmers in the area.
1. Turnkey EPC Project Scope & Facility Scale
- Main cold storage cluster: Volume 45,000 m³ divided into 4 independent chambers with temperature -22°C ÷ -25°C, equipped with Drive-in high-rise shelf system containing 10,000 standard pallet positions.
- High-capacity freezing equipment complex: Including 2 Stainless steel mesh IQF conveyor belts with a capacity of 1,000 kg/h/line, 4 Air Blast Freezers with a temperature of -40°C specializing in freezing whole shrimp and peeled shrimp for export to the EU, US, and Japan.
- NH3 central refrigeration compressor station: 4 Mycom Kobelco 2-stage screw compressor clusters driving VFD inverter, combined with 3 combinations of 304 stainless steel evaporative condenser saving 25% of monthly electricity consumption.
2. Heavy-Duty Insulation Engineering Against Coastal Saline & Acidic Soil
- Camlock molded PIR panel warehouse shell made in Long An: 150mm thick PIR panel density 42 kg/m³, 2 sides covered with Colorbond corrugated iron C5M salt resistant and B1 fire resistant according to QCVN 06:2022/BXD.
- Reinforcing pile foundations to prevent muddy geological subsidence: Ca Mau's ground has a weak clay mud layer 15-20m thick. Tan Long designed the D500 centrifugal pile foundation system deeply immersed in the compact sand layer, combined with ventilated concrete beams to raise the floor 1.2m above the ground to prevent frost heave.
- Absolutely airtight insulated door system: Install T-Light cold sliding door 304 stainless steel frame and PVC quick rolling door at the loading and unloading dock area.
3. Coastal Anti-Corrosion Protection for Refrigeration Coils
Geographic location near the sea with very high salt concentration and air humidity makes outdoor metal equipment susceptible to rust and rot after only 2-3 years. Tan Long has synchronously applied high-end material solutions:
- Evaporative condenser shell and heat exchanger tube beam: 100% made from seamless SUS304L stainless steel, hot-dip galvanized steel support frame with coating thickness > 85 µm withstands ASTM B117 salt spray test of over 2,000 hours.
- Indoor fan blades and connecting screws: The fan blades are cast in aluminum alloy, electrostatic epoxy coated to prevent salt adhesion, all bolts and screws are made of SUS316 stainless steel.
- Freezing room panel: Use PVDF painted corrugated iron surface resistant to sea salt and industrial chlorine cleaning chemicals of seafood factories.
4. Functional Zoning Plan of Ca Mau Cold Storage Complex
| Functional Division | Area / Capacity | Design Temperature | Applied Refrigeration Technology |
|---|---|---|---|
| Raw material receiving & processing area | 650 m² | +12°C to +15°C | The central cooling unit blows softly, avoiding dehydration of fresh shrimp |
| IQF conveyor freezing chamber | 250 m² | -40°C to -45°C | Stainless steel mesh IQF conveyor belt 1,000 kg/h |
| Air Blast Freezer | 180 m² | -35°C to -40°C | Freezing whole fish and shrimp blocks for export |
| Commercial total freezer warehouse (4 chambers) | 45.000 m³ | -22°C to -25°C | Indoor unit with fan blowing 40m away, Drive-in shelf system |
Technical FAQs on the Ca Mau Seafood Processing Project
1. What anti-subsidence foundation engineering was deployed for a 10,000-ton cold storage on soft clay soil in Ca Mau?
Tan Long applies D500 pre-stressed centrifugal concrete pile technology deeply embedded in the compact gravel layer at a depth of 38m, combining cross-braced pile cap and naturally ventilated hollow raised floor, preventing 100% of the risk of differential settlement and ground swelling due to soil freezing.
2. Does the shrimp IQF tunnel freezing line in Ca Mau comply with European Union (EU Code) export standards?
The IQF line is made entirely of food-standard SUS304 stainless steel by Tan Long, the CIP system automatically cleans and disinfects the ice mesh surface, and meets HACCP certification, US FDA and strict standards of the EU market.
