Ca Mau is Vietnam's number one "shrimp capital," with brackish water shrimp farming area exceeding 280,000 hectares and shrimp export revenue exceeding 1 billion USD per year, concentrated in... Nam Can, Ngoc Hien, Dam Doi, Cai Nuoc, along with the bustling fishing grounds of the Western Sea in the fishing port town. Doc River (Tran Van Thoi). To preserve the quality of exported shrimp and meet the stringent standards of the most demanding markets such as the US, Japan, the EU, and Australia, the cold storage and deep-freezing system is a crucial factor determining the success or failure of seafood processing plants in Ca Mau.
Tan Long Refrigeration and Electrical Engineering Joint Stock Company We are a leading industrial EPC general contractor specializing in consulting, design, and construction. Cold storage for shrimp larvae, deep-freeze tunnels, and a complex of seafood cold storage facilities in Ca Mau.. Tan Long's system is designed to be integrated with Mycom/Bitzer compressors, B1/B2 fire-retardant PIR panels, and a 24/7 SCADA control system, resulting in energy savings of up to 30%.
1. Specific Cold Storage Requirements of the Ca Mau Shrimp Farming and Processing Region
- Ultra-fast freezing of tiger prawns and whiteleg prawns (Nam Can, Ngoc Hien, Dam Doi): After initial processing, shrimp should be immediately transferred to an IQF conveyor belt or a blast freezer. -35°C to -40°C Within 45-60 minutes, the core temperature of the shrimp reaches -18°C. This extremely rapid freezing speed ensures that the fine ice crystals do not tear the cell membranes, so when thawed, the shrimp meat retains its firmness and crispness, the shell remains shiny, and the head does not turn black.
- Long-term frozen storage for export (-22°C to -25°C): Maintain a stable deep-freeze temperature with an error of $pm 0.5^circ ext{C}$, humidity 85% – 90% To prevent water sublimation, which causes surface freezing (freezer burn) that makes shrimp spongy and dark yellow in color.
- Saline environment and weak coastal soil: The air in Ca Mau has a very high salt content, combined with the muddy soil along the riverbanks, requiring load-bearing pile foundations and heat exchangers to be coated with a high-grade chemical anti-corrosion layer.
