Quick Freezing Equipment

Quick Freezing Equipment – Industrial IQF Freezer Solutions for Fruits, Vegetables, Seafood, and Meat

HSYL’s Quick Freezing Equipment, also known as IQF (Individual Quick Freezing) machines, is designed for rapid and uniform freezing of food products, including fruits, vegetables, seafood, meat, and prepared foods. This equipment is widely used in commercial food processing facilities, cold storage warehouses, and industrial food production lines. By utilizing advanced airflow design and precise temperature control, HSYL IQF freezers ensure that each product freezes individually, maintaining product quality, texture, color, and nutritional value.

Quick freezing is critical in the modern food industry because it prevents the formation of large ice crystals, which can damage cell structure and reduce shelf life. HSYL’s IQF solutions combine efficiency, hygiene, and versatility, meeting the requirements of high-volume frozen food production.

Process Flow of Quick Freezing

The IQF process is a multi-step operation designed to freeze food products rapidly while preserving quality:

1. Pre-Cooling or Blanching (Optional)

• Vegetables & Fruits: Certain vegetables and fruits undergo blanching before freezing to deactivate enzymes that may affect flavor, color, and texture.

• Seafood & Meat: Products are pre-cooled to ensure uniform freezing. Ice water sprays or chilled air may be used.

2. Feeding and Spreading

• Products are evenly distributed on the conveyor belt or mesh tray to ensure maximum exposure to freezing air.

• Overlapping is avoided to prevent partial freezing and to ensure uniform individual freezing.

3. Rapid Freezing

• Products enter the IQF freezing chamber, where high-velocity, cold air circulates through the freezing tunnels.

• Air temperatures can range from -30°C to -50°C, depending on product type and capacity.

• The freezing time is controlled precisely to prevent large ice crystal formation, preserving product integrity.

4. Product Separation

• The high-speed airflow ensures products are individually frozen, preventing clumping or sticking.

• This step is critical for downstream processing such as portioning, packaging, and IQF storage.

5. Discharge & Packaging

• Frozen products are discharged onto a collection conveyor.

• Depending on production needs, products may be packaged immediately or stored in cold storage at -18°C or below.

6. Optional Secondary Freezing / Hard Freezing

• Some high-moisture products undergo secondary freezing to stabilize the internal structure and ensure extended shelf life.
