Seafood and fish are highly perishable. Rapid freezing in a blast freezer prevents the formation of large ice crystals, which can damage cell structure. This helps maintain natural texture, flavor, and nutritional quality after thawing.
Blast Freezer: Used for quick freezing of fresh catch, typically reducing the product core temperature to -18°C or lower within a few hours.
Freezer Room: Designed to store already frozen seafood at-18°C to -25°C for long-term preservation and distribution.
Frozen seafood and fish should be stored at a constant temperature of-18°C or below. Some high-value products like tuna may require ultra-low temperatures (up to-60°C) for premium quality storage.
With proper freezing and storage conditions, seafood can be stored for 6–12 months, depending on the type of fish, packaging quality, and handling practices.
Blue Cold offers both Ammonia (NH₃) and Freon-based refrigeration systems. Ammonia systems are suitable for large processing plants due to efficiency and cost-effectiveness, while Freon systems are ideal for smaller facilities or decentralized operations.
High-velocity air circulation in blast freezers ensures uniform and rapid cooling of seafood, reducing freezing time and maintaining product quality. Blue Cold designs systems to optimize airflow for faster processing.
Yes. Blue Cold designs tailor-made solutions based on plant capacity, type of seafood processed, and customer requirements, ranging from small fishery units to large industrial seafood exporters.
We design systems with strict compliance to international food safety standards. Key measures include maintaining stable temperatures, hygienic construction materials, corrosion-resistant equipment, and reliable temperature monitoring.
Our systems use advanced compressors, efficient heat exchangers, and high-quality insulation to minimize energy consumption while maintaining fast freezing times, helping processors reduce operational costs.
Routine maintenance involves:
* Cleaning evaporators and condensers to prevent salt deposits
* Inspecting refrigerant levels and compressor performance
* Checking door seals and insulation integrity
* Ensuring fans and motors operate efficiently
Yes. We provide complete after-sales support, including preventive maintenance, spare parts supply, and technical guidance, ensuring uninterrupted freezing and storage operations.
