Blast Freezer Room
Specially designed for slaughterhouses and seafood factories, this blast freezer achieves fast quick-freezing at ultra-low temperature about -30C~-40C. It effectively retains product freshness and quality.
With durable food-grade materials, excellent insulation and reliable refrigeration system, it runs stably under 24-hour heavy load. Intelligent control and complete safety devices guarantee safe, efficient and hygienic operation.
✅ Ultra-Rapid Freezing & Zero-Quality-Loss
- Maintains a consistent air temperature of -35°C to -40°C (down to -60°C for ultra-low-temp options).
- Delivers powerful, uniform airflow to ensure every product is frozen evenly, eliminating thaw drip loss and preserving juiciness.
✅ Energy-Efficient & Superior Insulation
- Constructed with 150–200mm thick high-density PU/PIR insulated panels (≥40kg/m³), offering ultra-low thermal conductivity to minimize cold loss.
- Equipped with high-efficiency compressors and intelligent PLC controls, reducing energy consumption by over 30% compared to traditional cold rooms.
✅ Hygienic, Durable & Safe Design
- Interior panels are made of food-grade 304 stainless steel, ensuring easy cleaning, corrosion resistance, and compliance with HACCP/ISO standards.
- Heavy-duty cold room doors with high-performance gaskets and built-in safety release locks prevent accidental lock-ins and maintain airtight sealing.
✅ Customized & Flexible Solutions
- Fully customizable in size, temperature range, and freezing capacity (2 to 50 tons per batch) to meet specific production needs.
- Designed for forklift or trolley operations, with optional accessories like sliding doors, racking systems, emergency lighting, and remote monitoring.
✅ Reliable Performance & Quick Installation
- Factory-prefabricated modular design allows for on-site assembly in just 1–2 weeks.
- Features top-tier components from Bitzer, Danfoss, and Schneider, ensuring stable 24/7 continuous operation and a service life of over 20 years.
