What is an IQF System?

IQF (Individual Quick Freezing) is an industrial freezing technology that rapidly freezes food products individually, without them sticking together. Unlike conventional bulk freezing methods, IQF systems freeze each product piece separately, making them easy to separate during storage and use.

How Does IQF Work?

In IQF systems, products travel on a conveyor belt exposed to high-velocity cold air flow. The product surface freezes rapidly first (crust freezing), then freezing is completed to the core. This process preserves the cell structure and maximizes quality after thawing.

IQF vs. Conventional Freezing

In conventional freezing, products are frozen in bulk, forming large ice crystals that damage cell structure. IQF technology forms small ice crystals through rapid freezing, preserving the product texture, color, aroma and nutritional values.

IQF Applications

  • Seafood: Fish fillets, shrimp, mussels, octopus
  • Meat products: Chicken pieces, meatballs, sausage slices
  • Vegetables: Peas, corn, broccoli, carrots, spinach
  • Fruits: Strawberries, raspberries, blueberries, cherries
  • Bakery: Dough products, croissants, pastries
  • Ready meals: Pizza toppings, ready meal components
