FAQ

What types of products can this quick freezer handle and what freezing speed can be achieved?
Our quick freezer is ideal for fish fillets, shrimp, squid, vegetables, fruit and other products requiring rapid freezing. Depending on model and product thickness, it can reach core temperatures of −18 °C or below within 30-90 minutes. We can customize the tunnel length, belt width and capacity to match your throughput needs.
How does the quick freezer preserve product quality and reduce freezer burn?
The unit uses high-speed cold air circulation and optimized airflow design to freeze products rapidly and evenly. This minimises ice crystal formation and preserves texture, color and nutrient content. Proper freezing also reduces drip loss during thawing, improving yield.
What energy-saving features and maintenance requirements apply to this quick freezer?
The machine includes flash-freeze zones, insulated panels, variable-speed fans and optional defrost systems to minimise energy use. Routine maintenance involves checking air filters, cleaning condenser coils and verifying belt alignment. With correct setup, energy consumption can be significantly lower than older freezing systems.
