Core Functional Characteristics
High-Efficiency Freezing: Rapid temperature reduction is achieved through refrigeration systems and airflow circulation; liquid nitrogen models can complete the core freezing process within 5 minutes, with some models reaching cooling rates of up to 50°C/min, keeping moisture loss (shrinkage) below 1%.
Low-Loss Preservation: Rapid freezing significantly minimizes ice crystal formation within food cells, preventing cell damage and juice loss; compared to traditional cold storage freezing, it reduces dehydration loss by over 15% and better preserves the food's original flavor and nutritional value.
Versatility Across Food Types: Suitable for almost all common food categories, including meat, seafood, fruits and vegetables, ready-made meals, and pastries; specialized models can be tailored for high-value or fragile food items.
Structural and Technical Characteristics
Compliant Materials: The main body is typically constructed from food-grade 304 stainless steel, while components in contact with food utilize wear-resistant, food-grade polymer materials, fully meeting HACCP food safety standards.
Diverse Technical Approaches: Systems generally fall into two categories-compressor-based refrigeration and liquid nitrogen phase-change refrigeration; some new liquid-based quick-freezers utilize an immersion design, consuming only 60% of the energy required by traditional equipment.
High Automation: Most models feature PLC intelligent control systems that allow for preset freezing curves tailored to specific foods; they automatically manage the entire process-including cooling, holding, and defrosting-while monitoring temperature fluctuations in real-time.
Performance Parameter Characteristics
Standard Operating Parameters: Core operating parameters for standard models include a freezing temperature of -32°C ± 2°C, a production capacity of 300–500 kg/h, and an operating power consumption of 4.4–7.1 kW; capacity and dimensions can be flexibly adjusted across different models to meet specific requirements.
